Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mechanism with hinge and sliding button is used for electrical connection, then reliable electrical connection is achieved, but device complexity increases
Solution Approach 1:
The device is divided into separable components: the sensor unit with its own terminal and the reader with connection terminals. This segmentation allows the sensor to be detached and replaced independently, simplifying the overall structure while maintaining reliable electrical connections through direct terminal contact.
Solution Approach 2:
The complex hinge and sliding button mechanism is completely removed from the design. Instead, a simple terminal contact system is extracted and used, achieving reliable electrical connection without the unnecessary mechanical complexity of the previous design.
2Stability of the object's composition
If rigid sensor structures are used for stable connection, then connection stability is improved, but design flexibility and miniaturization are limited
Solution Approach 1:
The sensor unit employs flexible printed circuit boards instead of rigid structures. This allows the sensor to be bent or shaped as needed for different applications while maintaining stable electrical connections through the flexible circuit traces, enabling both design flexibility and miniaturization.
Solution Approach 2:
The connection system transitions from rigid static structures to a more dynamic flexible circuit design that can adapt to different mounting configurations and sensor shapes, providing both stability and versatility.
3Volume of moving object
If compact design is implemented, then device miniaturization is achieved, but heat transfer efficiency deteriorates
Solution Approach 1:
A heat dissipation plate is introduced as an intermediary component between the sensor unit and the reader. This plate provides a dedicated thermal conduction path that efficiently transfers heat from the compact sensor to the reader's heat dissipation structure, maintaining heat transfer efficiency despite the compact overall design.
Solution Approach 2:
The heat dissipation function is copied from a separate cooling system into an integrated heat dissipation plate within the reader structure, allowing compact design while preserving thermal management capabilities.
