Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal lines are arranged to cross each other to form complex interconnection patterns, then the functionality and signal transmission capability are improved, but electrostatic charges accumulate leading to breakdown and circuit failure
Solution Approach 1:
The patent introduces electrostatic discharging units as intermediary components between signal lines and secondary discharging lines. These units act as mediators that safely transfer and dissipate accumulated electrostatic charges, preventing direct breakdown of the signal lines while maintaining the complex interconnection pattern necessary for signal transmission functionality.
Solution Approach 2:
The patent extracts the harmful electrostatic charges from the signal lines by providing dedicated discharging pathways. The electrostatic discharging units and secondary discharging lines form a separate charge dissipation system that removes the harmful electrical charges without interfering with the normal signal transmission function of the original signal lines.
2Reliability
If electrostatic discharging units are added to prevent breakdown, then circuit reliability is improved, but device complexity increases due to additional components
Solution Approach 1:
The patent merges the electrostatic discharging function with the existing signal line structure by integrating electrostatic discharging units at specific intersection points. Rather than adding completely separate discharging systems, the design combines charge dissipation functionality with the interconnection structure, reducing overall device complexity while maintaining reliability.
Solution Approach 2:
The patent segments the electrostatic protection function into discrete electrostatic discharging units that are selectively placed at specific locations where charge accumulation is most likely to occur. This segmented approach allows protection to be provided only where needed, rather than requiring a complete restructuring of the entire signal line system.
