Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate reset control lines are used for each gate driving circuit, then signal transmission reliability is improved, but wiring space increases and cost increases
Solution Approach 1:
The patent merges multiple separate reset control lines into a single shared reset control line that serves multiple gate driving circuits. This consolidation reduces the total wiring space required while maintaining signal transmission reliability through proper signal distribution to all connected circuits.
Solution Approach 2:
The reset control line is designed with multi-functionality, serving as a universal control line that can reset multiple different gate driving circuits (first, second, and third gate driving circuits) simultaneously. This universal line replaces what would traditionally require multiple dedicated lines, reducing overall wiring complexity.
2Object-affected harmful factors
If separate reset control lines are used for each gate driving circuit, then signal interference is reduced, but manufacturing cost increases
Solution Approach 1:
By combining multiple reset control lines into one shared line, the patent reduces the total number of wiring elements that need to be manufactured and assembled, thereby lowering manufacturing costs. The design maintains signal integrity through proper circuit architecture that prevents interference.
Solution Approach 2:
The universal reset control line serves multiple gate driving circuits, reducing the bill of materials and assembly complexity. This multi-functional approach lowers manufacturing cost while the circuit design ensures minimal signal interference through shared control architecture.
3Reliability
If multiple signal input terminals are used for different gate driving circuits, then signal transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent employs a single reset control line that functions universally across multiple gate driving circuits, reducing device complexity. This shared control architecture simplifies the overall device structure while maintaining reliable signal transmission to all connected circuits through proper signal distribution.
