LED Module Fastening Device with Notch Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for LED modules are limited to specific widths, preventing the use of LED modules narrower than intended for fastening rails, and often require tools for assembly and optical system attachment.
Innovation Solution
A fastening device with a first fastening area featuring a notch for non-rotatable positioning and a second fastening area with a mandrel for secure tool-free attachment, allowing LED modules of varying widths to be securely fastened to rails of different standards, and enabling tool-free optical system connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mounting rails with fixed width are used to attach LED modules, then secure attachment is achieved, but only LED modules of the specified width can be used
Solution Approach 1:
The mounting device is divided into two functional parts: a first mounting area that attaches to the mounting rail and a positioning element that holds the LED module. This segmentation allows the device to adapt to different LED module widths while maintaining secure attachment through the rail interface.
Solution Approach 2:
The mounting device is designed with a universal interface for mounting rails while incorporating adjustable positioning elements that can accommodate LED modules of various widths. The device thus serves multiple width specifications through a single design.
2Ease of operation
If traditional fastening systems are used for LED modules, then secure attachment is achieved, but tools are required for assembly and optical system attachment
Solution Approach 1:
The mounting device incorporates self-aligning and self-fastening features that enable tool-free assembly. The positioning element and mounting area work together to automatically secure the LED module without requiring external tools, while maintaining reliable attachment.
3Adaptability or versatility
If LED modules of narrower width are attached to standard mounting rails, then versatility is improved, but rotational stability deteriorates
Solution Approach 1:
The positioning element incorporates a notch with an asymmetric geometry that engages with the LED module edge. This asymmetric design prevents rotation by providing a mechanical stop that only allows insertion in the correct orientation, thereby ensuring rotational stability for narrower LED modules.
4Reliability
If mounting devices with multiple fastening points are used, then attachment security is improved, but device complexity increases
Solution Approach 1:
The mounting device combines the first mounting area for rail attachment and the positioning element for LED module holding into a single integrated component. This merging provides secure attachment at multiple points without requiring separate fastening devices, thereby reducing overall system complexity.
