Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light-emitting element arrays are arranged in the same plane for multi-layer display, then the stereoscopic effect is improved, but the light-emitting elements overlap each other causing image interference
Solution Approach 1:
The patent extends light-emitting element arrays from a two-dimensional plane to a three-dimensional space by positioning them at different heights (Z-axis) relative to the rotary portion. This vertical separation prevents overlap while maintaining the multi-layer display structure needed for stereoscopic effects.
2Object-generated harmful factors
If light-emitting element arrays are positioned at different heights to prevent overlap, then light source interference is reduced, but the structural complexity increases
Solution Approach 1:
The patent employs a rotary mechanism that dynamically rotates multiple panels with light-emitting element arrays at different heights. This dynamic rotation allows the system to maintain precise spatial separation of light sources while achieving complex multi-layer display patterns, reducing the need for static structural complexity.
