Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single contact pad is used with the chip, then the device complexity is reduced, but the card must be inserted in a specific orientation which reduces ease of operation
Solution Approach 1:
The contact interface is segmented into multiple contact pads (first contact pad and second contact pad) positioned at different locations on the card. This segmentation allows the card to be inserted in different orientations while maintaining proper electrical contact, thereby improving ease of operation without significantly increasing device complexity
Solution Approach 2:
The contact pads are arranged in asymmetric positions relative to the chip location. The first contact pad is positioned at a first location and the second contact pad at a second location, creating an asymmetric contact configuration that enables orientation-independent insertion while maintaining functional integrity
2Adaptability or versatility
If the chip is positioned at a specific location, then the manufacturing precision is improved, but the card requires specific insertion orientation which reduces adaptability
Solution Approach 1:
The chip and contact pad configuration is designed to serve multiple insertion orientations universally. The same chip position and contact pad arrangement support both correct and reversed insertion orientations, making the card adaptable to different insertion directions while maintaining manufacturing precision through standardized chip placement
3Adaptability or versatility
If dual contact pads are added to enable any orientation, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The first contact pad and second contact pad are merged into a unified contact interface system that works together with the chip. Both contact pads are integrated with the same chip through the substrate, combining multiple contact functions into a single coordinated system that improves adaptability while minimizing the increase in device complexity
