Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensors, switches, and fixing portions are separated and connected by wires, then each component can be independently positioned, but the structure becomes very complicated and disconnection/short circuit risks increase
Solution Approach 1:
The patent integrates sensors, switches, and fixing portions onto a single circuit board, merging previously separate components into one unified structure. This eliminates the need for multiple wires and connections, directly resolving the contradiction by maintaining independent positioning capability while dramatically reducing structural complexity and connection risks.
2Ease of manufacture
If sensors, switches, and fixing portions are separated and connected by wires, then component assembly is flexible, but manufacturing cost increases due to frequent defects and assembly difficulty
Solution Approach 1:
By integrating all components onto one circuit board, the patent transforms a multi-step assembly process involving separate component mounting and wire connections into a single integrated unit assembly. This maintains manufacturing flexibility while significantly reducing assembly process complexity and associated costs.
3Reliability
If components are connected by wires, then electrical connections can be established, but disconnection and short circuit problems occur
Solution Approach 1:
The patent eliminates wire connections by integrating sensors, switches, and fixing portions directly onto the circuit board with built-in electrical traces. This merging approach completely removes the wire connection interface, thereby eliminating disconnection and short circuit risks while maintaining reliable electrical connectivity.

AI summary
A gear-shift lever module with various sensors integrated on one circuit board may include a module housing, the integrated circuit board disposed in the module housing, a position sensor, a manual mode switch and a connector. The position sensor senses a shift position of a gear-shift lever and is disposed on the integrated circuit board at a position corresponding to a hinge portion at a lower end of the gear-shift lever. The manual mode switch is disposed on the integrated circuit board at a position corresponding to a manual mode of the gear-shift lever and senses the manual mode by being pressed by the gear-shift lever when the gear-shift lever is positioned for the manual mode. The connector is electrically connected with the position sensor and the manual mode switch.
