Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate support member is used to dispose the conductive structure, then the conductive structure can be properly assembled, but the assembly process becomes complicated and device complexity increases
Solution Approach 1:
The patent merges the support member and conductive structure into a single integrated component. The conductive structure is formed directly on the button member, eliminating the need for a separate support member. This integration simplifies the assembly process while ensuring reliable electrical connection between the electrode member and circuit board.
2Reliability
If a separate support member is used for the conductive structure, then proper electrical connection is achieved, but material costs and device complexity increase
Solution Approach 1:
The support function and conductive function are merged into a single structure. The button member itself serves as both the mechanical support and the conductive path, reducing the total component count while maintaining reliable electrical connection for biometric signal detection.
3Reliability
If the conductive structure is disposed on a separate support member, then electrical connectivity is maintained, but the assembly process becomes difficult and time-consuming
Solution Approach 1:
The conductive structure is pre-formed on the button member during the button manufacturing process, before final assembly. This preliminary integration ensures that the conductive path is already established and positioned correctly, eliminating the need for separate handling and assembly steps for the conductive structure.
4Ease of operation
If a curved contact portion is used in the conductive structure, then vertical assembly is enabled without damage, but manufacturing precision requirements increase
Solution Approach 1:
The contact portion of the conductive structure is formed with a curved shape that complements the button member's geometry. This curvature allows the conductive structure to flex and make proper contact during vertical assembly, accommodating dimensional variations while ensuring reliable electrical connection.
