Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional packing methods are used with gaps between the panel and box body, then the manufacturing process is simpler, but secondary impacts occur during transportation causing damage to the liquid crystal panel
Solution Approach 1:
The packing box employs elastic retractable members (springs) that can dynamically adjust to the liquid crystal panel's position and dimensions. These springs provide elastic cushioning and automatically adapt to manufacturing tolerances, eliminating the need for precise fixed gaps while preventing secondary impacts through continuous elastic contact.
Solution Approach 2:
The packing box utilizes elastic properties of the retractable members to change the contact parameters between the panel and box body. The elastic deformation of springs allows the system to accommodate varying gap sizes while maintaining constant protective contact force, transforming the rigid gap parameter into a flexible elastic parameter.
2Ease of manufacture
If the manufacturing tolerance of the box body is increased, then the manufacturing process becomes more flexible, but the gap between the box body and inner object becomes uncontrollable, reducing protection performance
Solution Approach 1:
The elastic retractable members self-adjust to accommodate manufacturing tolerances without requiring external intervention. The springs automatically compensate for gap variations through their elastic deformation, maintaining consistent protective contact pressure regardless of the actual gap size within tolerance ranges.
Solution Approach 2:
The packing box pre-installs elastic cushioning elements that are already positioned to provide protective contact before any impact occurs. These springs are pre-compressed or positioned to immediately engage with the liquid crystal panel, providing beforehand cushioning that prevents secondary impacts regardless of gap variations.
3Strength
If a hard packing box is used with rigid structure, then the rigidity and structural strength are improved, but the cushioning performance is reduced requiring additional soft retaining walls
Solution Approach 1:
The packing box merges the rigid box body structure with elastic retractable members into a unified protective system. The springs are integrated directly into the box body walls, combining the structural strength of the rigid container with the cushioning function of elastic elements, eliminating the need for separate soft retaining walls.
Solution Approach 2:
The packing box employs a composite structure combining rigid materials for the box body with elastic materials for the retractable members. This composite approach allows the rigid container to provide structural strength while the elastic components provide cushioning, achieving both rigidity and protection without additional complexity.

AI summary
A liquid crystal panel packing box and a liquid crystal panel packing method are provided. The packing box is equipped with an elastic retractable member assembled in an accommodating groove thereof. The elastic retractable member is memory metal and can generate stretching and retracting effects with the change of temperature to thereby fix liquid crystal panels disposed in the packing box. Accordingly, in the processes of packing and transporting the liquid crystal panels, the seamless assembling between the liquid crystal panels and the packing box is realized, the damage caused by collision between edges of the liquid crystal panels and a box body of the packing box is avoided, the secondary impact generated resulting from the shift of the liquid crystal panels is eliminated and the safety is improved consequently.
