Engineering Contradiction Analysis
1Reliability
If the pad on the FPC board is coupled to liquid crystal glass, then electrical connection is established, but the pad falls off due to external forces causing disconnection
Solution Approach 1:
The connection system is segmented into multiple independent components: the FPC board with pad, the electromagnetic plug, and the tension detection circuit board. This segmentation allows the electromagnetic plug to bear the external forces while the pad maintains its electrical connection function, preventing pad fall-off while ensuring connection reliability.
Solution Approach 2:
The electromagnetic plug acts as an intermediary between the FPC board and the external environment. It absorbs and withstands external forces (tension, compression, bending) that would otherwise be transmitted to the pad, thereby protecting the pad from falling off while maintaining electrical connection through the tension detection circuit board.
2Stability of the object's composition
If the electromagnetic plug is embedded between glass substrates, then connection stability is improved, but manufacturing complexity increases
Solution Approach 1:
The electromagnetic plug and tension detection circuit board are nested within the sandwich structure of the glass substrates. The electromagnetic plug is positioned between the first and second glass substrates, with its joint exposed from the outer edge, allowing stable embedding while maintaining a relatively simple overall structure that integrates well with the existing glass panel manufacturing process.
