Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of connecting apparatuses are provided for different wiper driving arms, then the assembly compatibility is improved, but the device complexity and cost increase
Solution Approach 1:
The connecting apparatus is designed with a universal structure that can accommodate multiple types of wiper driving arms. The main body includes a penetrated hole for receiving pivotal shafts of different shapes, elastic clamping pieces for securing various arm types, and positioning grooves that adapt to different geometries. This single multi-functional design replaces the need for multiple specialized connecting apparatuses, reducing complexity while maintaining compatibility across different wiper driving arm types.
2Adaptability or versatility
If multiple types of connecting apparatuses are provided for different wiper driving arms, then the assembly compatibility is improved, but the loss of substance increases due to unnecessary component waste
Solution Approach 1:
By designing a single universal connecting apparatus that can securely attach various types of wiper driving arms, the invention eliminates the need for manufacturers and consumers to stock multiple specialized connecting apparatus types. This reduces material waste from unused spare parts while ensuring proper assembly compatibility through adaptive features like the penetrated hole, elastic clamping pieces, and positioning grooves.
3Adaptability or versatility
If multiple types of connecting apparatuses are provided for different wiper driving arms, then the assembly compatibility is improved, but the manufacturing cost increases
Solution Approach 1:
The universal connecting apparatus consolidates multiple specialized designs into a single product, reducing manufacturing costs through economies of scale. Instead of producing several different connecting apparatus types with varying features, manufacturers can mass-produce one standardized design that accommodates all wiper driving arm types, lowering per-unit costs and simplifying production processes.
Solution Approach 2:
The invention merges the functions of multiple specialized connecting apparatuses into a single unified design. By combining the securing mechanisms, positioning features, and attachment interfaces into one versatile apparatus, the patent eliminates the need for separate production lines and inventory management for multiple product types, thereby reducing overall manufacturing costs.
