Sliding Fastening Pin for Lighting Apparatus Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting apparatus manufacturing processes are cumbersome due to the need for multiple screws for assembling substrates and optical elements, and require separate cabling for electrical connections, making them difficult to assemble and maintain.
Innovation Solution
A lighting apparatus design featuring a fixture with a fastening hole having a first and second portion, where the light source module is slidably moved along the fixture's surface, allowing for both mechanical fixation and electrical connection through a single process using a fastening pin that moves within the hole, eliminating the need for separate cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws are used for assembling substrates and optical elements, then mechanical fastening is achieved, but device complexity and assembly time increase
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated fastening pin structure that simultaneously secures both the substrate and optical element to the frame, eliminating the need for multiple separate screws and reducing assembly complexity
Solution Approach 2:
The fastening pin is designed as a multi-functional component that performs both mechanical fastening and electrical connection functions, serving multiple purposes with a single element rather than requiring separate components for each function
2Reliability
If separate cabling is used for electrical connections, then electrical connectivity is achieved, but assembly time and manufacturing complexity increase
Solution Approach 1:
The patent merges the electrical connection function with the mechanical fastening pin, creating an integrated component that establishes both structural and electrical connections simultaneously during a single assembly operation, eliminating separate cabling steps
Solution Approach 2:
The fastening pin is designed as a multi-functional component that performs both mechanical fastening and electrical connection functions, serving multiple purposes with a single element rather than requiring separate components for each function
3Strength
If traditional screw fastening is used, then mechanical fixation is achieved, but ease of maintenance deteriorates
Solution Approach 1:
The patent divides the fastening system into modular components including the fastening pin, fastening hole, and detachable light source module, allowing individual parts to be easily replaced or serviced without affecting the entire assembly structure
