Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single projection source is used, then device complexity is reduced, but the ability to display multiple pictures simultaneously is limited
Solution Approach 1:
The patent applies periodic action by rapidly switching the light path transformation unit between different optical states at a predetermined frequency. This allows a single projection source to sequentially project different pictures to different projection regions, creating the effect of simultaneous multi-picture display through time-division multiplexing
Solution Approach 2:
The light path transformation unit is designed to be dynamically switchable between N different optical states. This dynamic capability allows the system to adaptively route light to different projection regions based on the current frame sequence, enabling flexible multi-picture display configurations
2Adaptability or versatility
If multiple projection sources are used to display multiple pictures, then the ability to display multiple pictures is improved, but device complexity increases
Solution Approach 1:
The patent makes a single projection source universal by enabling it to serve multiple projection regions through the light path transformation unit. The same light source can sequentially project different pictures to different regions, eliminating the need for multiple dedicated projection sources while maintaining full multi-picture display capability
Solution Approach 2:
The light path transformation unit acts as an intermediary between the single projection source and multiple projection regions. It mediates the light routing by switching between different optical states, allowing one source to effectively serve multiple destinations without requiring multiple sources
3Ease of operation
If images are switched at high frequency, then the visual experience is improved, but the control complexity increases
Solution Approach 1:
The control unit coordinates the image switching and light path transformation based on frame sequences, ensuring that the switching frequency matches the display requirements. This controlled feedback mechanism maintains visual quality while managing system complexity
