Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If metal conductive wires are placed close together to transmit signals, then data transmission capability is improved, but signal crosstalk increases causing transmission loss and errors
Solution Approach 1:
The patent introduces earthing lines as intermediary elements between adjacent conductive wire areas. These earthing lines act as mediators that provide alternative current paths and electromagnetic shielding, reducing the direct electromagnetic coupling between first and second conductive wires. By placing earthing lines in between the conductive wire areas, the patent creates a buffering zone that minimizes signal crosstalk while preserving data transmission capability.
2Productivity
If conductive wire area is expanded to accommodate more wires, then signal transmission capacity is improved, but electromagnetic interference between wires increases
Solution Approach 1:
The patent divides the conductive wire area into distinct first and second conductive wire areas, with earthing lines creating spatial separation between them. This segmentation approach allows the system to accommodate multiple conductive wires for enhanced transmission capacity while preventing excessive electromagnetic interference by maintaining controlled distances between adjacent wire groups through the earthing line barriers.

AI summary
The present disclosure provides a touch panel which at least comprises a sensing area, a conductive wire area, and earthing lines. The conductive wire area surrounds the sensing area and is electrically connected to the sensing area, and the conductive wire area comprises a first conductive wire area and a second conductive wire area. The earthing lines are set between the first conductive wire area and the second conductive wire area. The touch panel can efficiently shield signal crosstalk between the first conductive wire area and the second conductive wire area by setting the earthing lines between the first conductive wire area and the second conductive wire area, thereby reducing the influence of signal crosstalk on efficiency of the touch panel.
