Derivatives Based on Independent Claim 1: Urinal Anti-Splash Device with Tapered Protrusions

Claim 1: A urinal anti-splash device comprising: an anti-splash body sized and shaped to couple to at least a portion of a urinal, the anti-splash body including: a first portion; a second portion opposite the first portion; a length extending from the first portion to the second portion; and an upper surface extending the length; a base couplable to the first portion and configured to extend in a direction substantially perpendicular from the first portion; a first plurality of protrusions extending outwardly from the upper surface of the anti-splash body and which taper downwardly in a direction toward the upper surface of the anti-splash body; and a second plurality of protrusions extending outwardly from the base, the second plurality of protrusions configured to extend in the direction substantially perpendicular from the first portion of the anti-splash body.

1. Material & Component Substitution

  • Derivative 1.1: Hydrophilic Fabric Protrusions with Bio-Enzymatic Core
    • Enabling Description: The anti-splash body and base are fabricated from a thermoplastic elastomer (TPE) matrix, such as styrene-ethylene-butylene-styrene (SEBS), molded with an integrated network of microfluidic channels. The protrusions consist of a woven, quick-wicking polyester or polyamide microfiber fabric, heat-bonded or ultrasonically welded to the TPE matrix. Each fabric protrusion encapsulates a microcapsule containing a lyophilized bio-enzymatic cleaning agent. Upon contact with urine and subsequent flushing water, the microcapsules slowly degrade, releasing enzymes (e.g., urease, protease) that break down uric acid and odor-causing organic compounds. The fabric's high surface area and hydrophilic nature rapidly absorb urine droplets, preventing ballistic splash, and then release the absorbed liquid downward through the microfiber structure and into the urinal drain.

  • Derivative 1.2: Viscoelastic Polymer with Tunable Stiffness Protrusions
    • Enabling Description: The anti-splash body and base are formed from a semi-rigid, high-density polyethylene (HDPE) for structural integrity, with the protrusions individually molded from a silicone-based viscoelastic polymer (e.g., polydimethylsiloxane, PDMS) with a Shore A hardness tunable between 10 and 30. These viscoelastic protrusions are mechanically anchored into recesses on the HDPE body/base. The tapering geometry of the protrusions allows for a gradient in stiffness along their length, with the tips being more flexible to absorb kinetic impact energy and the bases stiffer to maintain structural uprightness. The surface of the PDMS protrusions incorporates a superhydrophobic coating (e.g., fluorinated silanes) to prevent urine adhesion, minimize residual film, and promote rapid droplet shedding, further reducing splash and accumulation.

2. Operational Parameter Expansion

  • Derivative 1.3: Cryogenic Urinal Anti-Splash Device
    • Enabling Description: This device is designed for specialized industrial or scientific facilities where cryogenic fluids (e.g., liquid nitrogen, liquid helium) are handled, and incidental splashing of biological waste or laboratory liquids needs immediate solidification and containment. The anti-splash body and base are constructed from a cryo-resistant composite material (e.g., carbon fiber reinforced polymer with low-temperature epoxy resin matrix) with protrusions also made from the same material. The device incorporates internal microfluidic channels connected to a closed-loop refrigeration system circulating a non-corrosive, low-temperature heat transfer fluid (e.g., fluorinert liquid). When activated, the system lowers the temperature of the protrusions to below -150°C. Any urine or liquid striking the surface instantly freezes, encapsulating splash particles, and is then directed into a specialized cryo-waste collection system, preventing traditional liquid splash and aerosolization.

  • Derivative 1.4: High-Throughput Public Venue Anti-Splash System with Dynamic Protrusion Actuation
    • Enabling Description: Intended for extremely high-traffic public venues, this system utilizes an anti-splash body and base with electroactive polymer (EAP) or shape memory alloy (SMA) based protrusions. Each protrusion (or discrete cluster of protrusions) is individually controllable via a low-voltage electrical signal. Integrated ultrasonic sensors continuously monitor urine stream impact points, velocity vectors, and droplet size distribution. A localized microcontroller, programmed with predictive splash dynamics algorithms, dynamically adjusts the stiffness, angle, and resonant vibration frequency of specific protrusion clusters in real-time (e.g., at >100Hz frequency) to optimally dissipate kinetic energy and direct urine flow. This minimizes splash-back across a wide range of impact velocities and angles characteristic of varied user habits in high-throughput environments.

3. Cross-Domain Application

  • Derivative 1.5: Industrial Chemical Spill Containment Pad
    • Enabling Description: The anti-splash body and base are scaled to industrial dimensions (e.g., 2m x 2m) and constructed from chemically resistant fluoropolymer (e.g., PTFE, PFA) for the main structural elements, and perfluoroelastomer (e.g., Kalrez) for the resilient protrusions. This system is designed to line industrial sumps, bund walls, or temporary spill containment areas for highly corrosive chemicals (acids, bases, solvents). The large, robust, tapered protrusions break the kinetic energy of falling or flowing chemical streams, preventing hazardous aerosols, secondary splash, and directing the liquid safely into a collection sump or drain. The chemical resistance ensures material integrity and extended operational lifespan in harsh environments. Fasteners include magnetic adhesion plates for rapid deployment on metallic surfaces or heavy-duty chemical-resistant anchors for concrete.

  • Derivative 1.6: Livestock Water Trough Splash Minimizer
    • Enabling Description: This anti-splash device is adapted for large communal livestock watering troughs. The anti-splash body, constructed from food-grade, UV-stabilized polypropylene with integrated antimicrobial additives, is designed to be secured along the inner perimeter of a trough via non-corrosive clips. The base, also molded polypropylene, extends horizontally over a filtered drain or recirculation pump intake. Large, flexible, hollow rubber protrusions (e.g., EPDM rubber) with varying lengths and internal baffles are coupled to both the body and base. These protrusions dampen water movement caused by animals drinking vigorously, preventing excessive spillage outside the trough, maintaining consistent water levels, and reducing water waste. The antimicrobial additives inhibit biofilm growth.

  • Derivative 1.7: Microfluidic Droplet Dispensing Array
    • Enabling Description: On a microscopic scale, the "anti-splash device" serves as a precision microfluidic array for controlled droplet generation and delivery in laboratory settings (e.g., for high-throughput DNA sequencing, drug screening, or cell culture). The "anti-splash body" is a silicon or glass substrate with precisely etched microchannels. The "protrusions" are micromachined pillars or arrays of tapered nozzles (e.g., fabricated from SU-8 photoresist or etched silicon) that guide and break up fluid streams from a micro-pump or syringe, ensuring uniform droplet size, precise deposition, and preventing aerosol contamination or cross-well splash in multi-well plates. The "base" is a micro-collector for directed droplet deposition into target wells.

4. Integration with Emerging Tech

  • Derivative 1.8: AI-Optimized Adaptive Anti-Splash System with IoT Sensors
    • Enabling Description: The anti-splash body and base are embedded with an array of piezoelectric impact sensors and pH sensors positioned to cover the entire splash zone. These IoT sensors continuously stream real-time data (impact force magnitude, spatial location, liquid pH, temperature) via a low-power wireless module (e.g., LoRaWAN) to a central gateway. An edge AI processor analyzes this data to identify individual user patterns, quantify splash events, and detect degradation of splash-reducing efficacy over time. The AI can then dynamically recommend predictive maintenance (e.g., "replace device within 7 days," "clean high-impact zone") or, in a more advanced version, adjust embedded micro-actuators (e.g., electroactive polymer filaments) within the protrusions to subtly alter their shape, stiffness, or vibration frequency for optimal splash reduction based on real-time usage profiles and environmental conditions. Data analytics on usage patterns also optimizes replenishment schedules for integrated scented modules.

    H -- Dynamic Shape/Stiffness Adjust --> A;
  • Derivative 1.9: Blockchain-Integrated Anti-Splash Device Lifecycle Management
    • Enabling Description: Each anti-splash device incorporates a tamper-proof RFID tag or NFC chip encoded with a unique globally unique identifier (GUID) linked to a decentralized blockchain ledger. Upon manufacturing, its precise material composition, batch number, and production date are recorded as an immutable transaction on the blockchain. During deployment, the installation location (e.g., GPS coordinates, facility ID) and date are timestamped on the blockchain by authorized maintenance personnel via a secure mobile application. Integrated passive sensors (e.g., thermochromic material or simple optical usage counters) detect cumulative usage cycles or visible degradation, triggering automated updates to the blockchain for maintenance logging or automated replacement requests. This provides immutable proof of product authenticity, transparent tracking of environmental compliance (e.g., recycling efforts), and verifiable service history for warranty claims and comprehensive supply chain transparency.

5. The "Inverse" or Failure Mode

  • Derivative 1.10: Low-Power Indicator Anti-Splash Device
    • Enabling Description: The anti-splash device incorporates a passive optical indicator system for visualizing impact zones. The anti-splash body and base are constructed from a clear or translucent polymer. The protrusions are designed with internal microchannels containing a low-cost, non-toxic, reversible pH-sensitive liquid indicator (e.g., bromothymol blue, cresol red). As urine (typically acidic pH) contacts the indicator liquid within the protrusions' microchannels, a localized, temporary color change occurs (e.g., blue to yellow). This color change provides a visual "hit map" of the most frequently impacted zones, which fades over time or with subsequent flushing with neutral water. This entirely passive system provides maintenance personnel with a visual guide for targeted cleaning without relying on active electronics or external power sources, ensuring efficient resource allocation and reducing unnecessary cleaning of unaffected areas.

    C -- Localized Color Change --> E[Visual Hit Map];
    E -- Fades with Time/Flush --> F[Cleaning Guidance];
    F --> G[Efficient Maintenance];
  • Derivative 1.11: Scheduled Deterioration Anti-Splash Device for Controlled Disposal
    • Enabling Description: The anti-splash device is manufactured from a biodegradable polymer blend (e.g., PLA/PCL copolymer) with engineered degradation kinetics tailored to a specific lifespan (e.g., 90 days). The protrusions are designed to progressively soften, lose their structural integrity, and eventually detach (or become functionally ineffective) after a predetermined number of usage cycles or prolonged exposure to typical restroom humidity, temperature, and microbial conditions. This lifespan can be calibrated via an embedded passive timer or a simple environmental exposure sensor. When the device reaches a critical degradation threshold, a permanent, visible color change (e.g., an inert dye released from a degrading sacrificial layer) alerts maintenance personnel that the device is due for replacement and simultaneously indicates it can be composted or recycled via a specific designated biodegradable waste stream, preventing over-usage of ineffective devices and promoting sustainable end-of-life management.

Derivatives Based on Independent Claim 11: Urinal Anti-Splash Device with Coupling Region

Claim 11: A urinal anti-splash device comprising: an anti-splash body configured to couple to a urinal wall, the anti-splash body including a first portion, a second portion opposite the first portion, and a longitudinal length separating the first portion from the second portion; a base couplable to the first portion of the anti-splash body, the base sized and shaped to cover at least a portion of a urinal drain; a coupling region configured to translate the base between a first position including the base oriented in a direction parallel to the anti-splash body and a second position including the base oriented in a direction substantially perpendicular from the base; and a plurality of protrusions coupled to the anti-splash body and the base.

1. Material & Component Substitution

  • Derivative 11.1: Multi-Durometer Thermoplastic with Integral Living Hinge Coupling Region
    • Enabling Description: The anti-splash body and base are co-molded from a multi-durometer thermoplastic elastomer (TPE), such as a blend of soft (Shore 30A) and rigid (Shore 80D) thermoplastic polyurethane (TPU). The anti-splash body and the central structural elements of the base utilize the rigid TPU for robust support, while the protrusions are formed from the softer TPU for optimal impact absorption and flexibility. The coupling region is an integrally molded, fatigue-resistant living hinge made from a highly flexible elastomer (e.g., thermoplastic polyolefin, TPO, or a lower durometer TPU), allowing repeated manual translation of the base between the parallel (storage/shipping) and perpendicular (deployed) positions without mechanical failure or the need for a separate perforated edge. This design significantly enhances durability for multiple deployments and removal for cleaning.

  • Derivative 11.2: Shape Memory Polymer Coupling with Heat Activation
    • Enabling Description: The anti-splash body and base are fabricated from a robust, UV-resistant polypropylene. The coupling region consists of a shape memory polymer (SMP) strip (e.g., a polyurethane-based SMP with a glass transition temperature (Tg) of approximately 60-70°C) embedded or co-molded between the anti-splash body's first portion and the base. The SMP is pre-programmed to assume a substantially perpendicular configuration when heated above its Tg. In its relaxed state (below Tg), the SMP allows the base to remain parallel to the anti-splash body for compact packaging and transportation. A localized heat source (e.g., a portable heat gun, hot water application) applies thermal energy, triggering the SMP to deform and hold the base in the perpendicular position, effectively "locking" it into place for deployment in the urinal.

2. Operational Parameter Expansion

  • Derivative 11.3: Marine Environment Anti-Splash Filter for Bilge Sumps
    • Enabling Description: The device is designed for marine bilge sumps to minimize splash-back of oily water during rough seas and pre-filter solid debris before pump intake. The anti-splash body is constructed from marine-grade, UV-stabilized ABS plastic, sized to fit a bilge wall, and secured with corrosion-resistant titanium fasteners. The base is also marine-grade ABS, shaped to cover a bilge pump intake, and features an integrated fine-mesh filter screen (e.g., 316L stainless steel mesh, nominal pore size 500 microns). The coupling region is a robust, lockable hinge mechanism allowing the base to be securely deployed perpendicular to the body. Protrusions are stiff, injection-molded nylon-6/6 filaments designed to deflect incoming water and reduce splash, while also preventing large debris (e.g., rags, plastic bags) from clogging the filter and pump.

  • Derivative 11.4: High-Temperature Industrial Slurry Splash Guard with Modifiable Configuration
    • Enabling Description: This device is applied in industrial processing plants to manage splash from high-temperature (up to 200°C), abrasive, and corrosive slurries or waste streams. The anti-splash body and base are precisely machined from a high-performance thermoplastic, such as PEEK (Polyether ether ketone), known for extreme chemical and thermal resistance. The protrusions are solid PEEK rods, integral to the structure, also maintaining high resistance. The coupling region is a robust PEEK-hinged mechanism equipped with high-temperature, chemically inert ceramic locking pins, allowing the base to be securely configured either parallel for compact storage/transport or precisely perpendicular for deployment around drains, tank overflows, or conveying belts. This modularity allows for on-site adaptation to varying industrial configurations and critical containment needs.

3. Cross-Domain Application

  • Derivative 11.5: Horticultural Nutrient Runoff Deflector for Hydroponics
    • Enabling Description: This device is scaled for hydroponic grow trays to efficiently direct excess nutrient solution runoff to a recirculation system while minimizing splash onto plant foliage or sensitive control equipment. The anti-splash body is a thin, flexible, UV-resistant PVC sheet designed to attach securely to the inner wall or perimeter of a hydroponic grow tray. The base, also PVC, is configured to extend over a nutrient collection channel or reservoir inlet. A flexible, waterproof coupling region (e.g., a molded elastomer hinge or a continuous flexible strip) allows the base to be bent and retained in position. Soft, tapered silicone "protrusions" (Shore A 40) facilitate the laminar flow of excess nutrient solution downwards, preventing turbulent splash, reducing nutrient waste, and optimizing collection efficiency.

  • Derivative 11.6: Automotive Underbody Fluid Deflector for Repair Shops
    • Enabling Description: This large, multi-segment device protects shop floors, mechanics, and other vehicles from splash-back during high-pressure automotive underbody washing or fluid draining operations (e.g., oil, coolant). The anti-splash body comprises articulated, interlocking panels of oil-resistant, high-impact polypropylene, configured to be magnetically or clamped to vehicle underbodies, lift arms, or hoists. The base, also polypropylene, is hinged to these panels and extends downwards to direct fluids into a collection pan or drain. The coupling region is a series of robust, quick-release locking hinges enabling rapid deployment and reconfiguration. The protrusions are large, flexible, segmented rubber flaps (e.g., nitrile rubber, Shore A 60) designed to absorb kinetic energy from high-pressure water jets or rapidly draining fluids, preventing wide-area splash.

  • Derivative 11.7: Biological Culture Media Aerosol Containment Grid
    • Enabling Description: Designed for use within biosafety cabinets or laminar flow hoods, this micro-scale device minimizes aerosol generation and cross-contamination during manual pipetting or automated dispensing of biological culture media. The "anti-splash body" is a sterile, autoclavable polycarbonate grid attached to the inner wall of a work area with quick-release clips. The "base" is a similar polycarbonate grid, hinged to the body, extending over a waste collection port. The "coupling region" is a sterile, chemical-resistant living hinge. The "protrusions" are fine, tapered, antimicrobial-coated polymer filaments (e.g., silver-ion impregnated polyoxymethylene, 50-100 µm diameter) that gently break the surface tension of dispensed droplets, preventing their rebound and directing them safely into the desired receptacle or waste container, maintaining sterility and user safety.

4. Integration with Emerging Tech

  • Derivative 11.8: AI-Guided Robotic Assembly for Adaptive Urinal Anti-Splash Devices
    • Enabling Description: This manufacturing process employs AI-guided robotic arms for precise assembly and configuration of adaptive anti-splash devices. The anti-splash body and base are produced separately using injection molding. The coupling region, a smart hinge with embedded micro-sensors (e.g., strain gauges) for feedback, is then robotically attached. AI vision systems inspect each component for optimal fit and function, ensuring geometric accuracy. For on-site installation, a separate autonomous service robot, equipped with a 3D LiDAR scanner and an articulated manipulator, analyzes the specific geometry of an individual urinal in real-time. The AI then calculates the optimal configuration (e.g., precise angle of the base relative to the body, whether to engage a removable feature) and directs the robot to articulate the coupling region to the precise perpendicular angle or to detach the base if required, ensuring a perfect, adaptive fit for any urinal model, including non-standard or aged fixtures.

  • Derivative 11.9: IoT-Enabled Self-Sanitizing Anti-Splash Device with Predictive Maintenance
    • Enabling Description: The device features integrated IoT sensors (e.g., proximity sensors to detect user presence, optical sensors to monitor surface cleanliness, pressure sensors at protrusion tips for impact data, airflow sensors for odor detection) that wirelessly transmit usage and environmental data to a cloud-based AI platform. The AI algorithm analyzes this data to predict optimal cleaning cycles and device replacement needs based on actual usage and degradation. Upon reaching a predefined usage threshold, detecting accumulating grime, or sensing elevated ambient odors, an integrated micro-sprayer system within the anti-splash body automatically dispenses a measured dose of an enzymatic cleaner. Alternatively, UV-C light emitters integrated into the device activate for localized sterilization. The coupling region is a robust, waterproof, solenoid-actuated hinge, allowing the base to automatically retract or extend for cleaning cycles, enabling unobstructed access to the drain, or adjust its position based on user preference or urinal flushing dynamics, all controlled by the IoT system.

5. The "Inverse" or Failure Mode

  • Derivative 11.10: Self-Disengaging Anti-Splash Device on Drain Blockage
    • Enabling Description: The device is designed to automatically disengage the base from covering the urinal drain if a plumbing blockage occurs. The base includes an integrated pressure sensor or water level sensor (e.g., capacitive or ultrasonic) that continuously monitors the drainage rate or water accumulation within the urinal bowl. If a blockage is detected (e.g., water level exceeds a predefined threshold for more than 10 seconds, or drainage rate drops below a minimum threshold), the coupling region, which is a tension-release mechanism (e.g., a frangible link or a spring-loaded detent activated by a solenoid), automatically releases. This allows the base to either float away or pivot clear of the drain, preventing the anti-splash device itself from exacerbating a plumbing blockage and providing immediate, unobstructed access for maintenance personnel to clear the drain. An integrated visual indicator (e.g., a brightly colored dye released from a sealed chamber) signals this disengagement.

  • Derivative 11.11: Reduced-Functionality Mode for Water Conservation
    • Enabling Description: The anti-splash device incorporates a passive, environment-responsive flow-restriction mechanism within the base, specifically designed to activate during periods of water scarcity or for optimization with ultra-low-flush urinal models. The base's apertures include a bimetallic strip or a hydrogel element that expands to partially restrict urine flow to the drain when exposed to low flow rates of flushing water (or prolonged dry conditions). This mechanism intentionally reduces the overall splash-reduction efficacy slightly by slowing drainage, but minimizes residual water pooling at the base and encourages more complete, albeit slower, evacuation of liquid, thus contributing to water conservation in specific operational modes. The protrusions on both body and base remain functionally active for splash reduction, but the base's internal flow dynamics are actively altered.

1. Material & Component Substitution

  • Derivative 18.1: Method using Hydrogel-Adhesive Backed Device
    • Enabling Description: The method comprises providing a urinal anti-splash device where the anti-splash body is backed with a reusable, repositionable hydrogel adhesive layer (e.g., based on polyacrylamide or polyvinyl alcohol, with a tack strength of 5-10 N/cm²) instead of traditional suction cups or permanent pressure-sensitive adhesive. The mounting step involves first cleaning and drying the back wall of the urinal, then firmly pressing the hydrogel-backed anti-splash body against this clean, dry surface, allowing the hydrogel to form a temporary, yet strong, adhesive bond. The placing step involves manually unfolding or attaching the base, which also features a hydrogel perimeter or localized hydrogel patches, over the urinal drain screen. The hydrogel provides robust adhesion when dry, yet allows for residue-free removal and repositioning after rinsing with water, enhancing reusability and simplifying installation and routine maintenance cycles.

  • Derivative 18.2: Method using Thermally-Activated Polymer Fasteners
    • Enabling Description: The method involves providing a urinal anti-splash device with integrated fasteners made of a thermally activated shape memory polymer (SMP) (e.g., a segmented polyurethane with a shape recovery temperature of 80°C). These SMP fasteners are initially molded to be soft and pliable. The mounting step includes positioning the anti-splash body against the clean urinal back wall and then applying localized heat (e.g., via a portable hot air tool or inductive heating element) to the SMP fasteners. Upon heating and subsequent cooling to ambient temperature, the SMP fasteners undergo a programmed shape recovery, rigidifying and contracting to form a secure, high-strength mechanical interlock with surface irregularities or pre-installed anchor points (e.g., small studs, hooks) on the urinal wall. The base is then configured and placed over the urinal screen. This provides a robust, semi-permanent attachment suitable for high-vandalism or heavy-duty environments.

2. Operational Parameter Expansion

  • Derivative 18.3: Rapid Deployment Method for Emergency Response Facilities
    • Enabling Description: This method is optimized for rapid deployment in temporary or emergency facilities (e.g., field hospitals, disaster relief zones, temporary shelters) where sanitation must be established quickly. It involves providing a pre-assembled urinal anti-splash device, where the coupling region is a quick-release snap-fit mechanism (e.g., molded from a flexible polycarbonate) that holds the base parallel to the body for compact storage and transport. The mounting step utilizes integrated high-tack, single-use, pressure-sensitive adhesive strips (e.g., VHB tape) on the anti-splash body for immediate, strong attachment to any clean, smooth vertical surface (e.g., temporary wall panels, portable urinal units). The placing step involves a single swift action to disengage the snap-fit and articulate the base into the perpendicular position over a pre-fabricated drain insert or temporary liquid collection point. The entire installation process is designed to take less than 30 seconds per unit, enabling rapid sanitation setup in critical situations.

  • Derivative 18.4: Automated Robotic Installation Method for High-Volume Restrooms
    • Enabling Description: This method employs an autonomous mobile robot equipped with a multi-axis manipulator arm, a 3D LiDAR vision system for environmental mapping, and an automated structural adhesive dispensing module. The robot navigates autonomously to a designated urinal, scans its interior to precisely map contours, and identifies the drain and optimal mounting points. It then retrieves a pre-configured anti-splash device (with body and base initially aligned parallel for compactness) from an onboard magazine. The robot precisely applies a fast-curing structural adhesive (e.g., UV-cured acrylic adhesive) to the rear surface of the anti-splash body, positions it on the urinal back wall, and applies controlled pressure until initial adhesion is sufficient (mounting step). Next, the robot articulates the coupling region, bending the base to the precise calculated perpendicular position, and ensures correct placement over the urinal drain screen using its vision system (placing step). This method ensures consistent, high-quality, and labor-efficient installations across large numbers of restroom units.

3. Cross-Domain Application

  • Derivative 18.5: Method for Configuring Acoustic Dampening Panels in Studios
    • Enabling Description: This method configures modular acoustic dampening panels in recording studios, concert halls, or home theater environments. It involves providing an acoustic panel (equivalent to the anti-splash body) with a hinged acoustic baffle (equivalent to the base). The panel includes primary sound-absorbing foam protrusions (e.g., anechoic wedges). The coupling region is an adjustable friction hinge that allows the baffle to move from a parallel position (flat against the main panel for transport or minimal absorption) to a perpendicular position (extending outward for increased absorption, corner bass trapping, or diffusion). The mounting step involves attaching the main acoustic panel to a studio wall or ceiling using specialized acoustic mounting hardware (e.g., Z-clips, impalers). The placing step then involves manually articulating the hinged baffle to a desired perpendicular angle to optimize sound absorption characteristics for specific frequencies or to address room modes.

  • Derivative 18.6: Method for Deploying Articulated Protective Guards for Machinery
    • Enabling Description: This method focuses on deploying articulated protective guards on industrial machinery to deflect debris or splash from coolants/lubricants. It involves providing a machine guard comprising a main shield (equivalent to the anti-splash body) fabricated from high-impact polycarbonate, and a hinged extension flap (equivalent to the base) with integral impact-absorbing rubber protrusions. The coupling region is a durable, adjustable friction hinge with detent positions for precise angle control. The mounting step attaches the main shield to the machinery frame using heavy-duty bolt-on brackets. The placing step involves bending the extension flap at the friction hinge to a desired perpendicular angle, positioning it to effectively deflect high-velocity metal shavings, cutting fluids, or other process by-products away from operators and sensitive machinery components, preventing splash and ensuring safety in the workspace.

It involves providing a main channel segment (equivalent to the anti-splash body) constructed from UV-stabilized HDPE, with a hinged collection spout (equivalent to the base) that includes integrated flow-directing fins (protrusions). The coupling region is a robust, click-lock hinge mechanism. The mounting step involves attaching the main channel segment to a rainwater downspout or a dedicated collection tank inlet using clamps or integrated mounting points. The placing step then configures the collection spout by snapping it into a perpendicular, downward-pointing position, ensuring efficient capture and direction of rainwater into a storage reservoir, while minimizing splash-out or overflow during heavy rainfall events.

    • Enabling Description: This method utilizes an Augmented Reality (AR) application running on a tablet or smartphone, capable of spatial mapping. The providing step includes the anti-splash device itself. The mounting step involves the user holding the device, while the AR app overlays a virtual holographic guide onto the live camera feed, indicating the precise optimal placement, vertical alignment, and angle for the anti-splash body on the urinal back wall, dynamically accounting for different urinal models and installation tolerances. Visual cues and audible instructions guide the user to press the device firmly into place. For the placing step, the AR guide shows how to bend the coupling region and accurately position the base over the drain screen, with real-time feedback on alignment and coverage, ensuring correct installation even for inexperienced personnel or complex urinal geometries.

  • Derivative 18.9: Smart Inventory Management & Just-in-Time Robotic Resupply
    • Enabling Description: The method integrates with a smart inventory management system. The providing step is triggered by IoT sensors embedded in the urinal detecting low anti-splash device efficacy (e.g., increased splash-back, odor metrics) or a predefined usage threshold, which automatically initiates an order for a replacement device. This order is routed to a robotic warehouse system which autonomously retrieves, packages, and dispatches the device. For installation, an autonomous last-mile resupply robot delivers the device directly to the restroom. Maintenance personnel then follow standard manual mounting and placing steps, but the system logs the installation via NFC tap on the device's embedded tag, automatically updating inventory levels, warranty records, and service history. This ensures just-in-time replacement, minimizes stockouts, and optimizes labor allocation for maintenance.

5. The "Inverse" or Failure Mode

  • Derivative 18.10: Self-Folding/Retracting Method for Cleaning Access
    • Enabling Description: The method describes a self-folding anti-splash device specifically designed to facilitate cleaning. The providing step involves an anti-splash device whose coupling region incorporates a heat-sensitive shape memory alloy (SMA) spring (e.g., Nitinol, with an activation temperature of 50-60°C). The mounting step is performed as usual, securing the anti-splash body to the urinal wall. For the placing step, the base is engaged in its perpendicular position. During routine cleaning operations, hot water (above the SMA activation temperature) is intentionally applied to the device. The SMA spring in the coupling region then automatically contracts or expands, causing the base to fold upwards and temporarily retract parallel to the anti-splash body, providing completely unobstructed access to the urinal drain and the lower bowl for thorough cleaning. Upon cooling to ambient temperature, the SMA spring relaxes, allowing the base to be manually returned to its perpendicular, deployed position.

  • Derivative 18.11: Method for Visual Indication of End-of-Life for Recycling
    • Enabling Description: The providing step includes an anti-splash device manufactured with a multi-layered polymer structure. An outer sacrificial layer contains a photoluminescent dye that progressively degrades under typical ambient UV light exposure (common in restrooms) over a calculated lifespan (e.g., 90 days). The mounting and placing steps are standard. As the outer photoluminescent layer degrades, a brightly colored (e.g., neon green or orange) inner layer, made from a distinct, recyclable polymer, becomes progressively more visible through the translucent outer layer, acting as a clear, unmistakable visual indicator that the device has reached its functional end-of-life. This method guides maintenance personnel to replace the device and correctly sort it for specialized polymer recycling streams, preventing premature disposal of still-functional devices and incorrect disposal of expired units.
