Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If modular display technology is used to create large screens by tiling multiple micro LED modules, then the screen size and manufacturing flexibility are improved, but height differences and gaps between modules occur causing deteriorated image quality
Solution Approach 1:
The holder is designed with a rotatable adjustment device that allows the display module to be dynamically positioned at different depths. By rotating the adjustment device, the module can be moved forward or rearward to compensate for height differences, enabling continuous position adjustment to achieve uniform module alignment across the display screen.
Solution Approach 2:
The system changes the positional parameter of the display module by allowing rotation of the holder at different angles. This parameter change enables the module to be positioned at various depths relative to the frame, thereby adjusting for height variations and achieving uniform alignment without requiring precise manufacturing tolerances.
2Stability of the object's composition
If display modules are securely fastened to the frame, then structural stability is improved, but the ability to adjust module positions after installation is lost
Solution Approach 1:
The holder incorporates a rotatable adjustment device that maintains secure fixation while enabling dynamic position adjustment. The magnetic coupling provides stable attachment, but the rotatable mechanism allows the module to be repositioned by rotating the holder, thus achieving both stability and adjustability after installation.
Solution Approach 2:
The adjustment device acts as an intermediary mechanism between the frame and the display module. It provides a controlled interface that allows position adjustment while maintaining secure connection, enabling operators to modify module positions without disassembling the entire apparatus.
3Ease of manufacture
If the display apparatus is installed in a fixed position, then installation simplicity is improved, but the ability to correct height differences requires disassembly which increases maintenance complexity
Solution Approach 1:
The rotatable adjustment device enables maintenance personnel to correct height differences by simply rotating the holder without disassembling the display apparatus. This dynamic adjustment capability simplifies maintenance operations while keeping the apparatus in its installed position, reducing the complexity associated with module repositioning.
