Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual assembly is used for commercial lighting products, then assembly flexibility and adaptability are maintained, but labor costs increase and automation cannot be implemented
Solution Approach 1:
The patent applies the dynamics principle by designing the clamping opening with a bell mouth structure where the distance between elastic clamping pieces gradually decreases from the inlet to the inside and then becomes larger. This dynamic geometric design allows the connector to automatically adapt to positioning deviations during automated assembly, enabling automation while reducing precision requirements.
2Reliability
If welding is used for electrical connections, then connection reliability is improved, but assembly complexity and cost increase
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with an elastic clamping mechanism (mechanical system). The elastic clamping pieces provide reliable electrical connection through contact pressure without requiring welding operations, thereby improving reliability while reducing assembly complexity and eliminating the need for specialized welding equipment and procedures.
3Adaptability or versatility
If fixed-angle mounting of driving circuit boards is required, then connection stability is improved, but adaptability to different lamp configurations decreases
Solution Approach 1:
The patent applies universality by designing the bell mouth structure with elastic clamping pieces that can accommodate driving circuit boards at different mounting angles. The gradual narrowing then expanding geometry of the clamping opening allows the same connector design to work with various lamp configurations (including sweeping requirements) without requiring precise angle control, making the system universally applicable.
4Manufacturing precision
If high precision automated assembly is implemented, then product quality is improved, but manufacturing cost increases
Solution Approach 1:
The dynamic bell mouth structure with elastic clamping pieces inherently compensates for positioning variations during automated assembly. This design allows standard automated assembly equipment to achieve acceptable quality without requiring high-precision positioning systems, thereby reducing manufacturing costs while maintaining product quality.
