Universal Mounting Ring for RFID Reader Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID reader mounting solutions compromise on both functionality and aesthetics, as they often require a dedicated housing that protrudes from the wall and does not match surrounding aesthetics, and are inflexible in terms of positioning and read range adjustment.
Innovation Solution
A universal mounting ring with a planar arcuate plate and downwardly depending tabs that allows for multiple mounting positions and adjustable placement within an electrical enclosure, accommodating various cover assemblies and enabling read range optimization by positioning the reader relative to the enclosure's inner surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reader is potted in a plastic housing to protect it from metal objects and maintain read range, then the reader's functional performance is improved, but the aesthetic appearance deteriorates as the housing protrudes from the wall and does not match surrounding cover plates
Solution Approach 1:
The mounting system is divided into separate functional components: a thin mounting ring that attaches to the junction box and a separate cover plate that provides aesthetics. This segmentation allows the functional housing to remain minimal while the aesthetic cover is separate, resolving the contradiction between protection and appearance.
Solution Approach 2:
A thin mounting ring acts as an intermediary between the functional reader housing and the aesthetic cover plate. This intermediary component provides the necessary mounting function while being visually unobtrusive, allowing both functional performance and aesthetic appearance to be satisfied simultaneously.
2Reliability
If a dedicated housing is used to mount the reader away from metal objects, then the reader's read range is maintained, but the device complexity increases and flexibility in positioning is reduced
Solution Approach 1:
The mounting ring is designed as a universal component that can be used with various reader models and junction box configurations. This multi-functionality reduces the need for specialized housings for each application, simplifying the overall system while maintaining the ability to position readers away from metal objects for optimal performance.
3Device complexity
If the reader is fixed in a specific position within the housing, then the mounting structure is simplified, but the ability to adjust read range and optimize positioning is lost
Solution Approach 1:
The mounting ring incorporates adjustable positioning features that allow the reader to be positioned at multiple locations along the ring. This dynamic positioning capability enables optimization of read range while maintaining a relatively simple mounting structure, as the adjustability is built into the ring design rather than requiring complex external mechanisms.

AI summary
A universal mounting ring has an arcuate or curved upper portion and a plurality of downwardly depending tabs. The universal mounting ring is configured to interface with an electrical enclosure, such as conventional electrical junction boxes to permit a radio frequency identification (RFID) reader to be secured within the enclosure and mate with a wide variety of enclosure cover assemblies manufactured by third parties. The downwardly depending mounting tabs are provided with multiple mounting positions such that the reader may be securely mounted at a plurality of positions relative to a cover assembly.
