Adjustable Lighting Finishing Structure for Recessed Fixtures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures with non-circular finishing sections face misalignment issues during installation, requiring time-consuming and costly reinstallation to correct, as the orientation of the finishing section is dependent on the position of the housing attachment structures.
Innovation Solution
A finishing section for recessed lighting fixtures featuring a trim structure with a shielding reflector and a trim ring, where the shielding reflector is attached to the trim ring, and a ring structure is rotatable relative to both, allowing for post-installation adjustment to align with other fixtures without needing reinstallation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the finishing section is attached to the housing using fixed attachment structures, then the finishing section maintains stable orientation, but misalignment cannot be corrected after installation
Solution Approach 1:
The patent applies the dynamics principle by making the attachment connection adjustable rather than fixed. The finishing section includes adjustment mechanisms (such as adjustable attachment structures or mechanisms allowing rotation/translation) that enable the orientation to be changed after installation. This resolves the contradiction by allowing the system to transition from a static, stable state to a dynamic, adjustable state, permitting misalignment correction while maintaining stability when properly aligned.
2Ease of manufacture
If the finishing section orientation is dependent on housing position, then the installation process is simple, but misalignment between multiple fixtures cannot be remedied
Solution Approach 1:
The invention introduces adjustable attachment structures that allow the finishing section to be repositioned and reoriented after initial installation. This dynamic capability enables installers to first perform simple installation and then make precision adjustments to achieve proper alignment between multiple fixtures, thereby resolving the contradiction between installation simplicity and alignment precision.
Solution Approach 2:
The patent incorporates preliminary adjustment capabilities into the attachment structures, allowing the finishing section to be pre-positioned or pre-aligned before final installation. This preliminary action enables alignment adjustments to be made easily, combining the simplicity of straightforward installation with the precision needed for accurate alignment between multiple fixtures.
3Manufacturing precision
If reinstallation is required to correct misalignment, then proper alignment can be achieved, but time and cost increase significantly
Solution Approach 1:
The adjustable attachment structures enable alignment corrections to be made in-place without requiring complete reinstallation. The finishing section can be detached and reattached at different orientations, or rotated/translated along guided paths, allowing alignment adjustments to be performed quickly and easily, thereby achieving high alignment accuracy without the time loss associated with full reinstallation.

AI summary
A finishing section for a recessed lighting fixture includes a trim structure that includes a shielding reflector and a trim ring. The shielding reflector is attached to the trim ring. The finishing section further includes a ring structure attached to the shielding reflector distal from the trim ring. The trim structure and the ring structure are rotatable relative to each other.
