Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional fusible switch assemblies use separate components for line base assembly and load base assembly, then the assembly is easier to manufacture individually, but the overall device size increases and requires larger enclosures
Solution Approach 1:
The patent combines the line base assembly and load base assembly into a single integrated fusible switch assembly. The line base assembly includes line bus connector assemblies and fuse clip assemblies, while the load base assembly includes lug assemblies, all integrated within one device. This merging reduces the overall device size and eliminates the need for separate enclosures for each assembly.
Solution Approach 2:
The integrated fusible switch assembly performs multiple functions within a single device: it provides line wire connections through line bus connector assemblies, fuse installations through fuse clip assemblies, and load wire connections through lug assemblies. This multi-functionality reduces the number of separate components needed while maintaining all necessary electrical connection capabilities.
2Ease of manufacture
If conventional fusible switch assemblies include multiple separate components, then each component can be optimized for its specific function, but the manufacturing cost increases due to higher material costs and assembly complexity
Solution Approach 1:
By merging the line base assembly and load base assembly into a single integrated device, the patent reduces the total quantity of materials needed for manufacturing. The integrated structure eliminates redundant materials that would be required for separate enclosures and mounting hardware, thereby reducing material costs while simplifying the manufacturing process.
3Reliability
If conventional fusible switch assemblies use traditional separate assembly designs, then each assembly can be independently tested and quality controlled, but the overall device complexity and size increase
Solution Approach 1:
The patent integrates the line base assembly and load base assembly into a single unified structure with common mounting features and alignment mechanisms. This integration reduces structural complexity while maintaining quality control capabilities through standardized manufacturing processes for the integrated assembly.
