Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scanning lines are directly connected to circuit elements without protection, then device complexity is reduced, but electrostatic breakdown risk increases
Solution Approach 1:
The patent introduces waveform wires as intermediary elements between scanning lines and circuit elements. These waveform wires serve as mediators that can be electrically connected to out-of-product wires to transfer static electricity away from sensitive circuit elements, while maintaining the overall simplicity of the scanning circuit structure.
Solution Approach 2:
The patent segments the scanning line system by introducing separate waveform wire components that can be independently connected to out-of-product wires. This segmentation allows the protection function to be added without requiring complete redesign of the scanning circuit, thereby limiting the increase in device complexity.
2Ease of manufacture
If multiple scanning lines are electrically connected through continuous wires, then manufacturing is simplified, but electrostatic isolation between product regions becomes difficult
Solution Approach 1:
The waveform wires are designed with waveform shapes that allow them to be cut at specific locations to electrically separate scanning lines between adjacent product regions. The segmentation is achieved by cutting the continuous waveform wire structure, which simplifies the manufacturing process compared to trying to create separate wire structures for each region.
Solution Approach 2:
The waveform wires are pre-configured with shapes that depict waveforms, allowing them to be cut along straight lines into pieces that provide the required electrical separation. This preliminary configuration enables easy manufacturing while ensuring proper electrostatic isolation is achieved through the cutting process.
3Reliability
If out-of-product wires are used for electrostatic protection, then circuit element reliability improves, but manufacturing precision requirements increase
Solution Approach 1:
The waveform wires serve as intermediaries that connect scanning lines to out-of-product wires, providing a buffer zone that reduces the precision requirements for direct connections. The waveform shape allows for some tolerance in alignment while still achieving proper electrical connection and electrostatic protection functionality.
