Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures with rotatable LED-based modules face challenges in wiring integrity and accessibility due to internal wiring layouts, which limit movement and increase installation and maintenance complexity.
Innovation Solution
A light fixture design featuring a central housing with a grommet for water-tight cord entry, rotatable modules with peripheral cords for strain relief, and a snap and lock hinge mount for easy installation and access, allowing for rotation while maintaining electrical reliability and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internal wiring layout is used in light fixture, then wiring is protected from external damage, but range of movement of light modules is limited and wiring integrity is compromised
Solution Approach 1:
The patent divides the wiring system into separate segments: a fixed internal wiring structure and a flexible peripheral cord system. The peripheral cords are routed through peripheral openings in the housing, allowing the light modules to rotate independently while the main internal wiring remains stationary and protected. This segmentation resolves the contradiction by allowing movement in one part of the system without compromising the integrity of the main wiring.
2Strength
If light fixture is mounted on ceiling through housing, then secure mounting is achieved, but accessibility for wiring and maintenance is reduced
Solution Approach 1:
The patent extracts the wiring access function from the main housing body by providing separate peripheral openings in the housing walls. These openings allow wiring connections to be made without removing the light fixture from its ceiling-mounted position. The mounting security is maintained through the central housing structure while wiring accessibility is improved through the extracted peripheral access points.
3Adaptability or versatility
If peripheral cords are used for rotatable modules, then range of movement is improved and wiring integrity is maintained, but device complexity increases
Solution Approach 1:
The patent employs flexible grommets or sealing elements in the peripheral openings to accommodate the movement of peripheral cords while maintaining environmental sealing. These flexible components allow the cords to rotate and move within their openings without compromising the integrity of the housing seal, thus managing the complexity through specialized flexible sealing solutions rather than rigid structures.

AI summary
Present embodiments provide a light fixture having rotatable light modules and an extendable hinged mounting assembly. The light modules are electrically coupled to the light fixture via a cord and a grommet/bracket feature which provides strain relief and a waterproof barrier. The extendable hinged mounting assembly allows the light fixture to be mounted onto a ceiling or other structure while providing a mounted position and an install position.
