Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the clearance between constituent members is reduced to achieve slimming down of display devices, then the device thickness is reduced, but static electricity buildup causes deformation and deterioration of display quality
Solution Approach 1:
The patent applies preliminary action by providing a light-shielding pattern formed by a conductor connected to ground before static electricity can cause deformation. This preventive measure dissipates accumulated static electricity in advance, preventing the harmful effects of electrostatic attraction between closely spaced optical members while maintaining the slim device profile.
2Reliability
If a dedicated ground wire is provided to dissipate static electricity, then display quality is maintained, but the structure becomes complex and manufacturing process is complicated
Solution Approach 1:
The patent merges the light-shielding function and the electrostatic discharge function into a single integrated structure. The light-shielding pattern serves dual purposes: it shields light to improve display uniformity and simultaneously acts as a ground connection to dissipate static electricity, thereby eliminating the need for separate ground wires and simplifying the overall structure.
Solution Approach 2:
The light-shielding pattern is designed to perform multiple functions simultaneously: light shielding for display uniformity and electrical conduction for static electricity dissipation. This multi-functional design eliminates the need for additional dedicated ground wires, reducing structural complexity while maintaining display quality.
3Length of moving object
If optical members are stacked in proximity to achieve slimming down, then device thickness is reduced, but electrostatic attractive force causes deformation and Newton ring interference
Solution Approach 1:
The patent converts the harmful electrostatic attraction into a beneficial dissipation path. By forming a conductive light-shielding pattern connected to ground, the previously harmful electrostatic charge is now safely discharged, preventing deformation and Newton ring interference while allowing optical members to remain in close proximity for slim device design.
