Solution Overview
Problem
Conventional LED illumination lamps require manual welding of flexible electrically conductive wires for electrical connection between the light source substrate and the driving board, preventing automatic assembly during manufacturing.
Innovation Solution
An electric connecting member with an input terminal and an output terminal, where the output terminal includes two contacts connected to the driving board and the input terminal has two connection heads connected to the light source substrate, allowing for mechanical insertion and resilient clamping for electrical connection without manual welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual welding of flexible wires is used for electrical connection, then reliable electrical connection is achieved, but automatic assembly cannot be implemented
Solution Approach 1:
The patent replaces the welding process (thermal/chemical connection) with a mechanical insertion and clamping system. The connection heads with resilient members mechanically clamp the contacts, eliminating the need for welding operations and enabling automatic assembly through simple insertion motions.
Solution Approach 2:
The patent introduces connection heads with resilient members as intermediary components between the driving board contacts and the light source substrate. These resilient members act as mediators that provide both mechanical support and electrical connection through clamping, replacing the direct welding process.
2Extent of automation
If resilient clamping is used instead of welding, then automatic assembly is enabled, but connection stability under vibration may be compromised
Solution Approach 1:
The patent employs resilient members that can dynamically adapt to variations in contact dimensions and positioning. The elasticity of these members allows them to maintain consistent clamping force despite dimensional tolerances or vibrations, providing stable electrical connection through dynamic adjustment rather than rigid fixed positioning.
Solution Approach 2:
The resilient members provide beforehand cushioning by absorbing dimensional variations and positioning tolerances before they can affect the electrical connection. This pre-compliance mechanism ensures stable connection even when manufacturing tolerances cause slight variations in contact dimensions.
