Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional connection devices are used to assemble display modules, then the display modules can be connected, but the assembly process requires significant manpower and time
Solution Approach 1:
The connection device is divided into multiple functional segments: coupling pieces for attaching to display modules, turning pieces for pivoting movements, and connecting pieces for joining adjacent segments. This segmentation allows each component to perform its specific function efficiently, enabling rapid assembly without requiring complex manual operations.
Solution Approach 2:
The connection device employs a nested structure where coupling pieces contain connecting pieces, which in turn contain turning pieces. This nested arrangement allows the entire connection mechanism to be compact yet fully functional, enabling quick deployment and assembly while reducing the space required for storage and handling.
2Ease of operation
If display modules are stacked for storage, then storage space is utilized, but significant manpower and time are required for assembly and storage operations
Solution Approach 1:
The connection device incorporates turning pieces that enable dynamic pivoting movements between display modules. This dynamic capability allows modules to be easily transitioned between stacked storage positions and deployed display positions, significantly reducing the manpower and time required for storage operations while maintaining ease of operation.
3Manufacturing precision
If connection devices are used to connect display modules, then modules can be joined, but seamless integration and minimal spacing are difficult to achieve
Solution Approach 1:
The connection device features locally optimized geometries at critical interfaces: coupling pieces have matching rectangular openings and protrusions for precise alignment, turning pieces have specific thicknesses and pivot points for accurate positioning, and connecting pieces have complementary shapes for tight fits. These local quality enhancements ensure seamless integration with minimal spacing between modules.
4Productivity
If traditional assembly methods are used, then display modules can be connected, but the process requires significant manual labor
Solution Approach 1:
The connection device is designed to be self-aligning and self-latching. The coupling pieces automatically align with matching features on adjacent modules, the turning pieces self-position at correct angles through their pivot mechanisms, and the connecting pieces automatically engage and lock. This self-service capability dramatically reduces manual labor requirements while maintaining ease of operation, as operators only need to guide the modules into position rather than perform complex manual assembly steps.

AI summary
A display device includes first and second display modules and first and second turning pieces that include a first coupling piece, a first turning piece, a second turning piece, and a third turning piece, a second coupling piece and a guiding device. When the first and second display modules are switched between folding and unfolding, the first turning piece pivots relative to the first coupling piece and the second turning piece, and the third turning piece pivots relative to the second coupling piece and the second turning piece. When the display module is switched from folded to unfolded, the other side of the first display module relative to the side is pulled, the side of the first display module is guided by one end of the guiding device and slides to the other end, the first and second display modules are symmetrically unfolded with the side edge as the center.
