Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a light source array with individually controllable lighting units is used to create spatial light effects, then the user experience is enhanced, but the difficulty of correctly mapping the light source array onto the display increases
Solution Approach 1:
The system automatically performs the mapping process without requiring manual user intervention. The control system captures images of the light source array and display, processes these images to determine relative positions, and establishes the mapping relationship automatically, making the system self-sufficient in the mapping task.
Solution Approach 2:
The manual mechanical process of physically mapping and aligning lighting units is replaced by an automated optical and computational process. The system uses camera imaging and image processing algorithms to determine spatial relationships, substituting manual alignment operations with automated digital analysis.
2Manufacturing precision
If manual mapping of the light source array is performed, then mapping accuracy can be achieved, but the complexity of installation and configuration increases
Solution Approach 1:
