Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the screen anti-peeping device is designed with fixed control lead positioning to match specific display modules, then manufacturing precision is improved, but adaptability deteriorates

Engineering Contradiction:

Improvecontrol lead positioning precisionVSAvoidcompatibility with different display modules

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements universality by designing the screen anti-peeping device with multiple electrode sets that can be selectively coupled to control leads at different positions. This allows a single anti-peeping device design to be compatible with multiple display module specifications, eliminating the need for separate designs for each display module type while maintaining precise electrical connections.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple electrode sets are provided for selective coupling, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvecompatibility with different display panelsVSAvoidnumber of electrode sets

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the electrode structure into multiple independent electrode sets, where each set corresponds to a specific control lead position. This modular segmentation allows selective activation of only the necessary electrode sets for a given display module, reducing the effective complexity while maintaining adaptability across different specifications.

Inventive Principle:

Principle #1Segmentation
