Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the front-facing camera is set under the screen to achieve true full screen, then the screen-to-body ratio is improved, but static electricity transmission is blocked causing electrostatic damage
Solution Approach 1:
The anode connecting line segment extends in the plane of the substrate rather than relying solely on vertical via holes. By utilizing the horizontal dimension to create an extended connection path, the patent bypasses the via hole blocking issue while maintaining electrical connection between the anode and anode power supply line.
Solution Approach 2:
The anode connecting line segment acts as an intermediary structure that bridges the gap between the anode and the anode power supply line. This intermediate connection path allows static electricity to be transmitted effectively without requiring direct vertical connections through the optical component region.
2Ease of manufacture
If the anode connecting line segment has small contact area with anode, then manufacturing is easier, but static electricity transmission is insufficient
Solution Approach 1:
The patent optimizes the contact area parameter between the anode connecting line segment and the anode to a specific range (5%-100% of anode area). This parameter adjustment ensures sufficient static electricity transmission capability while maintaining manufacturing feasibility. The optimal contact area allows effective electrostatic dissipation without excessive manufacturing complexity.
