Adjustable Merchandiser Light Fixture With Rotating Serrated Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures for merchandisers require replacement to modify the angle of illumination, lacking adjustable features that allow for different orientations of the light source without reattachment.
Innovation Solution
An adjustable light fixture assembly featuring an arcuate bracket with a dovetailed clip and cooperative serrations, enabling rotatable adjustment of the light source up to 180° within the fixture, allowing for various orientations without the need for replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional light fixtures are secured to the merchandiser using a magnet or fastener, then the light fixture is firmly attached, but the light fixture cannot be adjusted to different orientations without replacement
Solution Approach 1:
The light fixture transitions from a static, fixed-orientation design to a dynamic, adjustable design. The clip mechanism allows the light fixture to be rotated and locked at different angles (0°, 45°, 90°, 135°, 180°) while remaining securely attached to the merchandiser, enabling dynamic reconfiguration of lighting orientation without replacement.
Solution Approach 2:
The light fixture is divided into separable components: a bracket that attaches to the merchandiser and a clip that holds the light source. This segmentation allows the clip to be independently adjusted and rotated relative to the bracket, providing orientation flexibility while maintaining secure attachment through the dovetailed engagement of the components.
2Loss of time
If conventional light fixtures require replacement to modify illumination angle, then the attachment structure remains simple, but time and resources are wasted on frequent fixture changes
Solution Approach 1:
The light fixture incorporates pre-designed adjustment mechanisms (serrations, guide members, tracks) that enable orientation changes to be made quickly and easily during installation or maintenance, rather than requiring complete fixture replacement. The mechanism is prepared in advance to accommodate multiple standard angles.
Solution Approach 2:
The adjustment mechanism is designed to be user-friendly and self-contained, allowing operators to reposition the light fixture to different angles without requiring specialized tools or expertise. The serrated engagement and guide members provide intuitive mechanical feedback for proper positioning.
3Adaptability or versatility
If the clip and bracket use cooperative serrations for adjustment, then rotatable adjustment is enabled, but the manufacturing precision requirements increase
Solution Approach 1:
The adjustment mechanism uses discrete angular parameters (0°, 45°, 90°, 135°, 180°) defined by the serration geometry. This parameterization allows for precise angular positioning through mechanical engagement of the serrations, while the standardized angle increments balance manufacturing feasibility with adjustment precision.

AI summary
A light fixture assembly including a bracket defined by an arcuate base and a clip dovetailed to the bracket within the base. The clip and the bracket define cooperative serrations to permit rotatable adjustment of the clip relative to the base about a longitudinal axis to provide different orientations for a light source within the case.
