Luminaire Receptacle Gasket With Visual Locking Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaire systems face difficulties in determining the correct installation of external modules due to the high force required for locking and the inability to feel when the module is properly positioned, especially for NEMA socket assemblies.
Innovation Solution
A receptacle assembly with a gasket featuring an indicator means that remains visible during installation, allowing operators to align and twist the external module correctly, ensuring proper positioning without complex modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a twist-lock mechanism is used to secure the external module, then the connection strength is improved, but the ease of operation deteriorates due to high locking force and difficulty in detecting correct positioning
Solution Approach 1:
The patent introduces visual feedback through indicator means (such as colored rings or markers) that provide immediate visual confirmation when the external module is correctly positioned and locked. This allows operators to detect proper installation without relying on tactile feedback, resolving the contradiction by maintaining strong twist-lock connection while significantly improving ease of operation through visual verification.
2Reliability
If the receptacle is mounted in an opening of the luminaire housing, then the electrical connection reliability is improved, but the ease of operation deteriorates due to limited accessibility and difficulty in monitoring installation
Solution Approach 1:
The patent extends the indicator means from the two-dimensional receptacle interface into the third dimension by projecting visual indicators (such as colored rings or markers) that extend beyond the housing opening. This allows operators to monitor installation status from a distance and at various angles, resolving the contradiction by maintaining secure mounted installation while improving accessibility and monitoring capability.

AI summary
Example embodiments relate to receptacle assemblies with gaskets. One example includes a receptacle assembly for a luminaire system. The receptacle assembly includes a receptacle and a gasket. The receptacle has a front side and a rear side. The front side is configured for receiving electrical contacts of an external module. The rear side is configured for extending in an opening of a housing, preferably a luminaire housing, and for being electrically connected to components in the housing. The gasket is configured for being located between the receptacle and the housing on which the receptacle is to be mounted. The receptacle assembly is provided with an indicator means at a location which is visible when the receptacle is mounted on the housing.
