Solution Overview

Problem

Existing RFID reader mounting solutions often compromise on either functional performance or aesthetic appeal, as they are susceptible to environmental factors like metal interference and require non-aesthetic plastic housings, and do not allow for variable positioning or matching with existing cover plates.

Innovation Solution

A universal mounting ring with multiple downwardly depending tabs and cutouts for secure attachment to electrical enclosures, allowing for adjustable positioning of RFID readers and other electronic devices within junction boxes, enabling better read range adjustment and compatibility with various cover assemblies for improved aesthetics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the reader is potted in a plastic housing to protect it from metal interference, then the reader's functional performance is improved, but the aesthetic appearance deteriorates

Engineering Contradiction:
Improvereader functional performanceVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The mounting system is divided into separate functional and aesthetic components: the reader remains in its protective plastic housing for reliability, while a separate decorative cover plate and mounting bracket system provides the aesthetic finish. This segmentation allows each component to fulfill its primary function without compromising the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A mounting bracket serves as an intermediary element between the plastic-housed reader and the decorative cover plate. This intermediary component enables the reader to be securely mounted while allowing the cover plate to provide the desired aesthetic appearance, thus resolving the contradiction between functional protection and visual appeal.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the reader is mounted in a fixed location, then the installation process is simplified, but the adaptability to different cover plates and positioning requirements deteriorates

Engineering Contradiction:
Improveinstallation simplicityVSAvoidpositioning flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The mounting bracket incorporates adjustable features that allow the reader to be positioned at multiple locations along the bracket. This dynamic positioning capability enables adaptation to different cover plate configurations and installation requirements while maintaining a straightforward installation process through the standardized bracket design.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting bracket is designed as a universal component that can accommodate various reader positions and work with different cover plate types. This multi-functional design allows a single bracket design to serve multiple positioning needs and compatibility requirements, thus providing adaptability without complicating the installation process.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If the reader housing protrudes from the wall surface to provide adequate read range, then the functional performance is improved, but the aesthetic integration deteriorates

Engineering Contradiction:
Improveread rangeVSAvoidaesthetic integration
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The mounting system utilizes the depth dimension of the junction box to resolve the protrusion issue. The reader is mounted within the recessed space of the junction box, allowing adequate protrusion for read range while the cover plate provides a flush aesthetic finish. This dimensional arrangement separates the functional requirement (protrusion) from the aesthetic requirement (flush surface).

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The cover plate acts as an intermediary element that conceals the protruding reader assembly. By positioning the reader within the junction box depth and using the cover plate to provide the visible surface, the system mediates between the need for reader protrusion (for read range) and the desire for a flush aesthetic finish.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.
