Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a touch sensor or keypad is attached to a precise position on the control surface, then operation recognition accuracy is improved, but assembly complexity and error rate increase due to precise positioning requirements
Solution Approach 1:
The patent combines the cover plate and printed circuit board into a single integrated assembly where the PCB is pre-mounted on the rear side of the cover plate. This merging eliminates the need for separate precise positioning of the PCB during final assembly, as the integrated structure ensures correct alignment of the touch sensor with the control surface markings.
Solution Approach 2:
The printed circuit board with the touch sensor is pre-assembled and positioned correctly on the rear side of the cover plate before the final assembly step. This preliminary action ensures that when the cover plate assembly is installed, the sensor is already in the correct position, eliminating positioning errors during final installation.
2Manufacturing precision
If a separate zig is used to position the printed circuit board, then positioning accuracy is improved, but productivity decreases due to additional assembly steps
Solution Approach 1:
The patent merges the positioning function into the integrated cover plate-PCB structure itself, eliminating the need for a separate zig component. The cover plate's rear side serves as the mounting surface for the PCB, and the integrated design provides inherent positioning features that eliminate the need for additional positioning zigs.
Solution Approach 2:
The patent removes the separate zig component from the assembly process. Instead of using a zig to position the PCB, the design directly mounts the PCB to the cover plate rear side, extracting the unnecessary intermediate component and simplifying the assembly process.
3Adaptability or versatility
If multiple separate components are assembled, then adaptability is improved, but assembly time and error rate increase
Solution Approach 1:
The patent combines multiple components (cover plate and printed circuit board) into a single integrated assembly unit. This reduces the number of separate assembly steps and minimizes the risk of assembly errors, while the modular nature of the integrated assembly maintains design flexibility for different applications.
