Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible circuit board and connectors are used to couple the electronic element to the circuit board, then the connection is reliable, but the element cost is high and the interior space is wasted
Solution Approach 1:
The patent merges the functions of the flexible circuit board and connectors into a single integrated elastic sheet unit. The elastic sheets with conductive portions directly couple the electronic element to the circuit board, eliminating the need for separate flexible circuit board and connector components, thereby reducing device complexity and assembly steps while maintaining connection reliability
Solution Approach 2:
The elastic sheet unit serves multiple functions simultaneously: it provides electrical connection through conductive portions, mechanical coupling through elastic sheets, and structural support through the integrated design. This multi-functional component replaces the flexible circuit board and connectors, reducing the number of parts needed
2Reliability
If a flexible circuit board and connectors are used to enable coupling, then the connection is established, but the element cost increases
Solution Approach 1:
The patent combines multiple components (flexible circuit board and connectors) into a single integrated elastic sheet unit. This merging reduces the quantity of substance by eliminating redundant components while maintaining the essential connection function through the elastic sheets with conductive portions
Solution Approach 2:
The invention extracts and eliminates unnecessary components (flexible circuit board and separate connectors) from the assembly, keeping only the essential elastic sheet unit that performs the coupling function. This extraction reduces component quantity and associated costs
3Reliability
If connectors and flexible circuit boards are used, then the electronic element can be coupled to the circuit board, but the assembly defect ratio increases
Solution Approach 1:
By merging the flexible circuit board and connectors into a single elastic sheet unit, the patent simplifies the assembly process. The integrated design reduces the number of assembly steps and potential error points, making manufacturing easier and reducing assembly defect ratios while maintaining connection reliability
