Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tapes are used to seal the opening of the packing box, then the box can be sealed, but the tape may be damaged or loosened, and the adhesion becomes weak
Solution Approach 1:
The patent removes the tape sealing element from the system and replaces it with a structural interlocking mechanism. The tongue plates and connecting components form a mechanical seal that eliminates the need for adhesive tapes, thereby solving the reliability and duration issues associated with tape degradation.
Solution Approach 2:
The packing box structure itself provides the sealing function through its interlocking tongue plates and connecting components. The design enables the box to seal itself without external sealing materials like tapes, achieving self-sustaining sealing performance throughout the product lifecycle.
2Reliability
If tapes are used to seal the box, then the opening can be sealed, but it leads to higher cost and lower efficiency due to extra packing process
Solution Approach 1:
The sealing function is merged with the structural components of the packing box itself. The tongue plates and connecting components that form the box structure also serve as the sealing mechanism, eliminating the need for separate tape application steps and thereby improving packing efficiency.
Solution Approach 2:
The box structure performs the sealing function autonomously through its interlocking design. No additional sealing materials or processes are required, as the tongue plates and connecting components inherently provide the sealing capability, thus streamlining the packing operation.
3Reliability
If tapes are used to seal the box, then the opening can be sealed, but some people may take away part of the products and seal the box again
Solution Approach 1:
The connecting components feature asymmetric designs where the protruding section width is larger than the connecting section width. This asymmetric geometry creates a mechanical interlock that prevents unauthorized opening or re-sealing, as the components cannot be separated without damaging the asymmetric fitting structure.
Solution Approach 2:
The interlocking connection between tongue plates and connecting components is designed to be permanent and non-reversible. Once connected, the asymmetric geometry ensures the components remain locked together, preventing tampering while maintaining a simple, cost-effective structure.
4Device complexity
If straight and symmetrical tongue plates are used, then the structure is simple, but the box cannot be tightly closed
Solution Approach 1:
The connecting components incorporate asymmetric geometric features where the protruding section has a larger width than the connecting section. This asymmetric design creates a mechanical interlock with the tongue plates that achieves tight closure while maintaining structural simplicity, preventing the tongue plates from separating under normal conditions.
Solution Approach 2:
The connecting components utilize curved or angled surfaces in their asymmetric geometry to create progressive engagement with the tongue plates. The curved transition zones allow for smooth insertion and secure locking, achieving tight closure through geometric form rather than complex mechanical structures.
