Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connecting wires and insulating materials are used between sensing electrodes, then electrical connection and signal isolation are achieved, but manufacturing complexity increases
Solution Approach 1:
The patent removes the connecting wires and insulating materials from the touch panel structure by electrically isolating each sensing electrode from its neighbors. This extraction of unnecessary components directly reduces manufacturing complexity while maintaining signal transmission reliability through the electrical isolation design
Solution Approach 2:
The sensing electrodes are segmented into electrically isolated units with complementary length patterns. This segmentation approach allows each electrode to be independently defined without requiring connecting structures, simplifying the manufacturing process while ensuring proper signal isolation
2Reliability
If connecting wires are used to connect sensing electrodes in series, then electrical connection is achieved, but the number of components and manufacturing steps increases
Solution Approach 1:
Instead of connecting sensing electrodes together with wires, the patent inverts the approach by electrically isolating each electrode and using complementary length patterns to establish the electrical connection relationships. This inversion eliminates the need for connecting wires and insulating materials, significantly easing the manufacturing process
3Reliability
If insulating materials are formed between connecting wires, then signal interference is prevented, but manufacturing complexity increases
Solution Approach 1:
The patent extracts and removes the insulating materials from the structure by designing electrically isolated sensing electrodes that do not require additional insulation layers. This eliminates the need for forming insulating materials between connecting wires, reducing manufacturing complexity while maintaining signal isolation through the inherent electrical isolation design
