Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an independent frequency division board is connected or independent circuit is designed, then electronic frequency division function is achieved, but design cost and welding cost increase, and production efficiency decreases
Solution Approach 1:
The patent merges the frequency division circuit directly into the horn assembly by integrating it onto the PCB connecting plate, which is already part of the horn structure. This combination eliminates the need for separate frequency division boards and their associated welding operations, thereby maintaining the electronic frequency division function while significantly improving production efficiency.
2Adaptability or versatility
If an independent frequency division board is connected or independent circuit is designed, then electronic frequency division function is achieved, but design cost and welding cost increase
Solution Approach 1:
The frequency division circuit is merged with the horn assembly by placing it on the PCB connecting plate that is already integrated into the horn structure. This approach consolidates multiple functions into a single integrated component, reducing both design complexity and manufacturing costs by eliminating separate frequency division boards and their associated welding operations.
Solution Approach 2:
The PCB connecting plate serves multiple functions: it provides electrical connections for the moving iron unit, structural support, and hosts the frequency division circuit. This multi-functionality reduces the need for separate components, thereby lowering design and manufacturing costs while maintaining all necessary functions including electronic frequency division.
