Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal material is used for switching device, then reliability and durability are improved, but production cost increases
Solution Approach 1:
The patent replaces expensive metal materials with plastic materials for the switching device housing and internal components. This substitution significantly reduces production costs while maintaining the functional requirements of the switching device through proper plastic material selection and design
Solution Approach 2:
The patent employs plastic materials that can be molded into complex shapes, allowing integration of multiple functions into single components. This reduces the total number of parts and assembly steps while maintaining structural integrity and functionality
2Ease of manufacture
If plastic material is used for switching device, then production cost is reduced, but structural complexity and assembly difficulty increase
Solution Approach 1:
The patent integrates multiple functions into single plastic components through mold design. The housing, internal structures, and mounting features are combined into unified parts that can be manufactured in one molding process, reducing assembly steps and overall complexity
Solution Approach 2:
The patent divides the switching device into modular plastic components that can be manufactured separately and assembled systematically. This segmentation allows for simplified manufacturing of individual parts while maintaining overall device functionality
