Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional display device structure is used, then the device is simple in structure, but static electricity accumulates causing damage
Solution Approach 1:
A conductive layer is introduced as an intermediary component between the optical layer and the circuit board. This conductive layer serves as a mediator to discharge static electricity accumulated in the optical layer to the circuit board, thereby protecting the display device from static electricity damage while maintaining a relatively simple overall structure.
Solution Approach 2:
The static electricity discharge function is extracted from the existing structure and implemented through a separate conductive layer. This allows the static electricity protection function to be added independently without fundamentally redesigning the entire display device structure, thus improving reliability while controlling complexity.
2Reliability
If static electricity discharge path is added, then damage due to static electricity is minimized, but the device structure becomes more complex
Solution Approach 1:
The conductive layer is designed to serve multiple functions: it provides static electricity discharge paths to both the circuit board and the receiving member, and it maintains electrical connection throughout the device. This multi-functionality allows a single component to address static electricity protection needs without proportionally increasing device complexity.
Solution Approach 2:
The static electricity discharge function is merged with the existing optical layer structure by placing the conductive layer between the optical layer and the circuit board. This integration approach allows the discharge path to be incorporated into the existing device architecture rather than adding completely separate protection systems.
