Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If flexible display module is fixed in the middle frame, then stability of display module is ensured, but alignment mistakes and repeat processing difficulties occur due to soft and curved characteristics
Solution Approach 1:
The patent applies preliminary action by pre-forming protrusion portions on the flexible substrate before the fixing process. These protrusion portions are positioned in advance to correspond with the through grooves on the middle frame, enabling automatic alignment when the flexible display is inserted and fixed, thereby eliminating alignment mistakes during the fixing process.
Solution Approach 2:
The patent introduces an intermediary alignment mechanism consisting of protrusion portions on the flexible substrate and corresponding through grooves on the middle frame. This intermediary structure mediates between the flexible display module and the middle frame, providing a precise alignment interface that guides the flexible display into the correct position during fixing.
2Reliability
If flexible display module is fixed in the middle frame, then protection of display module is achieved, but difficulty repeat process occurs due to soft and curved characteristics
Solution Approach 1:
The protrusion portions are pre-formed on the flexible substrate during the manufacturing process, before the fixing operation. This preliminary preparation ensures that during repeat processing, the alignment features are already in place, eliminating the need for complex alignment operations and enabling easy repeat processing.
Solution Approach 2:
The alignment system is designed to be self-aligning through the protrusion portions and through grooves. The flexible display module automatically positions itself correctly when inserted into the middle frame, eliminating the need for external alignment tools or complex positioning procedures, thereby simplifying repeat processing.
3Ease of operation
If traditional LCD module is used, then easy fixing is achieved due to glass substrate rigidity, but flexibility and bending capabilities are lost
Solution Approach 1:
The patent segments the fixing system into two functional parts: the flexible substrate with protrusion portions and the middle frame with through grooves. This segmentation allows the flexible substrate to maintain its bending capability while the through grooves provide the structural guidance and fixing function, combining the advantages of both flexible and rigid components.
Solution Approach 2:
The patent employs the flexible substrate with pre-formed protrusion portions as a flexible component that maintains adaptability for bending while providing alignment features. The protrusion portions are formed on the flexible substrate itself, allowing the substrate to remain flexible and bendable while still providing precise alignment during the fixing process.
