Movable Support for Recessed Light Electronic Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recessed lighting fixtures make it difficult and time-consuming to remove and replace electronic components due to limited access through small illumination apertures, requiring users to reach blindly and maintain awkward positions.
Innovation Solution
A light fixture with a movable support structure that can transition between an operation position and a service position, allowing electronic components to be easily accessed and replaced through a larger service space adjacent to the illumination aperture, reducing the need for blind reaching and awkward hand positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic components are mounted inside the enclosure through the illumination aperture, then the fixture structure is compact and simple, but the components become difficult to access and replace
Solution Approach 1:
The support structure is made movable rather than fixed, allowing it to transition between a retracted position (where components are accessible through the aperture) and an extended position (where components are mounted away from the aperture). This dynamic capability resolves the contradiction by enabling both easy access during maintenance and proper component mounting during normal operation.
Solution Approach 2:
The support structure is divided into a fixed portion (attached to the enclosure) and a movable portion (which carries the electronic component). This segmentation allows the movable portion to be independently positioned, enabling components to be accessed through the aperture while maintaining a compact overall structure.
2Ease of operation
If the illumination aperture is kept small (3-5 inches diameter), then the fixture maintains a compact design, but the service space becomes difficult to access
Solution Approach 1:
The movable support structure dynamically changes the effective service space by moving the electronic component closer to the aperture during maintenance, thereby improving accessibility without requiring the aperture itself to be enlarged.
3Ease of operation
If electronic components are mounted on the side walls of the enclosure, then the fixture structure is simple, but the components require awkward hand positions for removal and replacement
Solution Approach 1:
The movable support structure allows the electronic component to be dynamically repositioned from side wall mounting to a location near the aperture center, transforming an awkward maintenance operation into a comfortable one without requiring permanent structural changes.
Solution Approach 2:
The movable support structure preliminarily positions the electronic component in an optimal location for maintenance before the actual removal operation begins, allowing the user to work in a comfortable hand position from the outset rather than struggling with awkward angles.

AI summary
A light fixture includes an illumination aperture and a normal illumination axis passing through a center of the illumination aperture perpendicular to a plane of the illumination aperture. The light fixture further includes a service space having a cross-section corresponding to a shape of the illumination aperture and extending along the illumination axis between on a support structure facing side of the illumination aperture. The light fixture has a movable support movably coupled to the light fixture. The movable support includes a mounting portion. An electronic component is removably mounted to the mounting portion. The movable support is movable between an operation position and a service position. When the movable support is in the service position, the mounting portion and electronic component are closer to the illumination axis than when in the operation position, and are preferably located wholly or partially within service space.
