Adjustable Trim Collar for Light Fixture Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recessed light fixtures with directional trims often require correct orientation during installation, leading to time-consuming and costly reinstallation when the housing is incorrectly installed, as existing attachment mechanisms restrict the trim's orientation.
Innovation Solution
An adjustable trim assembly with a collar and mounting members that can be detached and reattached at alternate points on the top flange, allowing for flexible orientation adjustment within the light fixture housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing directional trims use fixed attachment mechanisms like torsion springs with brackets, then the trim can be securely attached to the housing, but the trim orientation is restricted and cannot be adjusted if the housing is installed in the wrong orientation
Solution Approach 1:
The trim assembly transitions from a fixed orientation to a dynamically adjustable orientation through multiple attachment points. The mounting members can be detached and reattached at different locations on the top flange, allowing the trim to adapt its orientation dynamically to match the housing installation orientation.
Solution Approach 2:
The attachment mechanism is segmented into multiple discrete attachment points distributed around the top flange perimeter. This segmentation allows selective engagement of different attachment points to achieve various orientations, transforming a single fixed-attachment system into a multi-configurable system.
2Manufacturing precision
If the housing is installed in the correct orientation from the beginning, then the directional trim will have the proper orientation, but this requires precise installation knowledge and may still require costly reinstallation if errors occur
Solution Approach 1:
The system prepares multiple pre-defined attachment point configurations in advance during manufacturing. These pre-positioned attachment points allow the trim to be oriented correctly without requiring precise installation knowledge, as the correct orientation can be achieved by simply selecting the appropriate pre-prepared attachment point pair.
Solution Approach 2:
The attachment geometry parameters are varied by providing multiple attachment points at different angular positions around the top flange. This parameter variation enables the same trim assembly to achieve different orientations by changing which attachment points are engaged, eliminating the need for housing reinstallation.
3Adaptability or versatility
If multiple attachment points are provided on the top flange, then the trim orientation can be adjusted, but the attachment mechanism becomes more complex
Solution Approach 1:
The mounting members serve multiple functions: they provide secure attachment, enable orientation adjustment, and allow for easy detachment and reattachment. This multi-functionality is achieved through a universal attachment interface design that works across all attachment points without requiring different mechanisms for each point.

AI summary
A light fixture includes a housing, a light module, and a trim assembly. The trim assembly includes a trim body, an upper flange, and an adjustable collar attached to the upper flange. The adjustable collar can attach to the upper flange in a plurality of different positions easily permitting adjustment of the orientation of the trim assembly with respect to the housing.
