Obviousness

Obviousness Analysis under 35 U.S.C. § 103 for US Patent 12359958

This analysis identifies combinations of prior art references that would render the claims of US Patent 12359958 obvious to a person having ordinary skill in the art (PHOSITA), along with the motivation for combining them. The independent claims (1, 11, and 15) introduce a bin level monitoring system with an optical volumetric sensor, a circuit board in an enclosure, a radio transmitter, and specific mounting mechanisms for both the enclosure and the sensor.

Combination 1: General System Architecture and Magnetic Enclosure Mounting

Claims Affected: Independent Claims 1, 11, and 15, specifically regarding the volumetric sensor, circuit board, enclosure, radio transmitter, battery, solar panel (Claim 5 and 14), and the magnetic mounting of the enclosure to the outside, sloped portion of the roof.

Prior Art References:

• WO2017137832A1 (Ubikwa Systems) [cite: WO2017137832A1]
• US20130293388A1 (Ingalsbe) [cite: US20130293388A1]
• US8350411B2 (Solarbridge) [cite: US8350411B2]
• US20120248267A1 (Spinelli) [cite: US20120248267A1]

Explanation of Obviousness and Motivation:

1. Core Monitoring System: Ubikwa Systems (WO2017137832A1) discloses a "method and a system for assessing the amount of content stored within a container," including sensing, processing the level signal, and transmitting data [cite: WO2017137832A1]. A PHOSITA would readily understand that "assessing the amount of content" in a bin containing fluent solid material (like feed) necessitates a volumetric measurement. The use of optical sensors, such as LIDAR or Time-of-Flight (ToF) sensors, for volumetric measurement of materials in bins was known in the art at the priority date of US12359958, and the patent itself identifies these as suitable optical sensors. Thus, Ubikwa Systems renders obvious the basic elements of sensing, processing, and generating bin level data using a volumetric optical sensor.

2. Remote Data Transmission: Ingalsbe (US20130293388A1) describes "cellular tank monitoring technology" for transmitting tank level data [cite: US20130293388A1]. A PHOSITA tasked with implementing Ubikwa's system for remote monitoring of agricultural feed bins would be highly motivated to integrate reliable, long-range cellular communication (as taught by Ingalsbe) to transmit the bin level data, a common requirement for such applications. This combination would lead to the predictable result of a remote bin monitoring system using a radio transmitter for cellular data transmission. US12359958 itself highlights the advantages of cellular (LTE Cat-M1) for long-range, power-efficient communication with existing infrastructure.

3. Autonomous Power Supply: Solarbridge (US8350411B2) teaches a "modular system for unattended energy generation and storage" utilizing solar panels and batteries [cite: US8350411B2]. To make the combined Ubikwa-Ingalsbe system self-sufficient and suitable for remote farm locations lacking grid power, a PHOSITA would be motivated to incorporate a solar power system (Solarbridge) to charge a battery. This would eliminate the need for external power wiring, reduce maintenance, and extend operational lifespan, resulting in predictable autonomous operation. This covers the battery (Claim 2) and solar panel (Claim 5 and 14) aspects, along with the enclosure containing these components.

4. Magnetic Enclosure Mounting: Spinelli (US20120248267A1) teaches using magnets for attaching electronic components [cite: US20120248267A1]. A PHOSITA, designing the external enclosure for the solar-powered remote monitoring system (derived from Ubikwa, Ingalsbe, and Solarbridge), would be motivated to adopt magnetic mounting (Spinelli) to achieve quick, easy, and non-invasive installation and removal on the exterior of the bin's roof. Mounting on a "sloped portion of the roof" would be a predictable design choice to optimize solar panel exposure, ensuring efficient charging. The patent itself explicitly mentions that magnets allow the system to be "quickly installed or removed without having to permanently modify the feed bin", indicating a known desirable outcome achieved by known means.

Therefore, the combination of Ubikwa, Ingalsbe, Solarbridge, and Spinelli, together with common design principles, would render obvious the broad system architecture and the magnetic mounting of the enclosure to a sloped roof.

Combination 2: Specific Sensor-Mounting Bracket

Claims Affected: Independent Claims 1, 11, and 15, specifically the detailed sensor-mounting bracket.

Prior Art References:

• WO2017137832A1 (Ubikwa Systems) [cite: WO2017137832A1]
• General Mechanical Design Principles and Common Knowledge of Bin Structures

Explanation of Obviousness and Motivation:

1. Need for Internal Sensor Mounting: Ubikwa Systems (WO2017137832A1) establishes the need to mount a sensor inside a container for assessing its contents.

2. Motivation for Specific Bracket Design: A PHOSITA designing a mounting bracket for a sensor inside a feed bin (as required by Ubikwa) would be motivated by several well-known functional objectives in such an environment:

   • Secure and Non-Invasive Attachment: Feed bins commonly feature lid openings with collars (as explicitly mentioned in US12359958,). A U-shaped hanger is a conventional mechanical element for suspending items, and fitting it over such an upright structural element (the collar) and securing it with a fastener through a hole are routine mechanical fastening techniques. This approach allows for secure attachment without permanent modification to the bin, a desirable feature for ease of installation.
   • Optimal Sensor Positioning: The sensor must be positioned to accurately view the feed level, typically by aiming downwardly into the bin. Designing a bracket with sequential vertical, angled, and horizontal portions provides a predictable mechanical solution to extend the sensor from the attachment point (the collar) and precisely orient it downwards into the bin.
   • Sensor Protection: The patent explicitly identifies the problem of protecting the sensor during bin refills from falling feed. Designing a bracket that strategically extends "away from the opening" using angled and horizontal portions to shield the sensor is a direct and predictable mechanical solution to this known problem, using conventional structural components to achieve protection.
   • Rapid Installation: The design of a hanger that easily fits over an existing collar and is secured with a common fastener directly addresses the desire for rapid and easy installation, as highlighted in US12359958.

Conclusion:
While the specific combination of a U-shaped hanger, its fastening to a lid collar, and the precise sequence of vertical, angled, and horizontal portions to position and protect the sensor is detailed, a PHOSITA would be motivated to combine known mechanical design principles and conventional structural elements to achieve the desirable and predictable functional objectives of secure, non-invasive, precisely aimed, and protected sensor mounting within a feed bin. These objectives are inherent in the problem of monitoring bin levels and protecting sensors in such environments. Therefore, the specific sensor-mounting bracket, when viewed in light of Ubikwa Systems and general mechanical design principles to solve known problems with predictable results, would be rendered obvious.
