Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple rods and connectors are added to implement foldable table function, then the foldable table function is achieved, but the structure becomes complex and assembly becomes inconvenient
Solution Approach 1:
The patent combines the foldable table supporting frames with the case lid structure itself. The supporting frames are integrated into the lid rather than being separate components, eliminating the need for multiple rods and connectors. This merging of functions reduces structural complexity while maintaining the foldable table capability.
Solution Approach 2:
The case lid serves multiple functions: it acts as both the closure for the case body and as the table surface when the supporting frames are unfolded. This multi-functionality eliminates the need for separate table components, simplifying the overall structure while achieving the foldable table function.
2Adaptability or versatility
If multiple rods and connectors are added to implement foldable table function, then the foldable table function is achieved, but the weight increases
Solution Approach 1:
By integrating the supporting frames into the case lid structure, the patent eliminates the need for separate rods and connectors. This reduction in component count directly reduces the overall weight of the case while maintaining the foldable table function.
Solution Approach 2:
The case lid serves as both the closure and the table surface, eliminating the need for additional table components that would add weight. This multi-functional design achieves the foldable table capability with minimal additional mass.
3Device complexity
If table panels are not tightly connected in existing foldable table systems, then the structure is simpler, but the storage capability is limited
Solution Approach 1:
The patent employs arc-shaped position-limiting members that work with position-limiting protrusions to control the rotation of supporting frames. This curved geometric design enables tight connection and stable positioning of the table panels while maintaining structural simplicity, thereby improving storage capability without excessive complexity.
