Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual wire welding is used to connect external connectors to circuit boards, then electrical connections can be established, but assembly efficiency is low and the process is complex
Solution Approach 1:
The patent replaces the mechanical wire welding process with an elastic connection system. The elastic connection assembly uses spring-loaded contacts that automatically engage with corresponding contacts on the circuit board when the end cap is assembled, eliminating the need for manual wire welding and enabling automated production.
Solution Approach 2:
The elastic connection assembly performs self-alignment and self-contact during assembly. The elastic deformation of the spring-loaded contacts allows them to automatically engage with the circuit board contacts without requiring precise manual positioning or welding operations, facilitating automated assembly.
2Reliability
If traditional connection methods are used, then electrical connections can be made, but waterproof sealing is compromised
Solution Approach 1:
The end cap is designed with a nested structure where the elastic connection assembly is housed within the end cap body. The end cap itself is nested within the light housing, creating multiple levels of protection. This nested design allows the waterproof seal to be maintained while accommodating the complex electrical connection mechanism.
Solution Approach 2:
The patent introduces a waterproof adhesive as an intermediary substance that seals the interface between the end cap and the light housing. This adhesive layer maintains the waterproof barrier while allowing the elastic connection assembly to function within the end cap structure.
3Productivity
If automated production is implemented, then assembly efficiency improves, but manufacturing precision requirements increase
Solution Approach 1:
The elastic connection assembly utilizes dynamic elastic deformation to accommodate variations in assembly positioning. The spring-loaded contacts can deflect and adjust to slight misalignments, allowing automated assembly equipment to achieve reliable electrical connections without requiring extremely high positioning precision.
Solution Approach 2:
The patent employs parameter changes in the form of elastic deformation and spring force to create a tolerance-friendly connection system. The elastic properties allow the connection to maintain electrical contact over a range of positions, reducing the stringency of manufacturing precision requirements for automated assembly.
