Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional folding tables use multiple components for stability and support, then the table has sufficient rigidity, but the device complexity and weight increase making it cumbersome to set up and carry
Solution Approach 1:
The patent combines multiple functions into integrated components. The separation biasing unit integrates the leg separation mechanism with the biasing force generation, while the movably coupling unit combines the leg attachment with the tabletop. This merging reduces the number of discrete components while maintaining structural rigidity through the coordinated action of these integrated units.
Solution Approach 2:
The biasing unit serves multiple functions: it separates the leg members, provides biasing force for automatic positioning, and couples the legs to the tabletop. The movably coupling unit simultaneously attaches legs to the tabletop and allows the necessary movement during setup. This multi-functionality reduces component count while maintaining structural integrity.
2Stability of the object's composition
If conventional folding tables use multiple components for support, then the table has sufficient stability, but the weight increases making it difficult to carry around
Solution Approach 1:
By merging the biasing mechanism and coupling mechanism into integrated units, the patent eliminates redundant components that would add weight. The separation biasing unit and movably coupling unit are designed as compact assemblies that provide both stability and portability.
Solution Approach 2:
The biasing unit automatically generates the force needed to separate and position the leg members without requiring additional heavy counterweights or complex mechanical advantage systems. This self-service approach reduces weight while maintaining stability through the elastic biasing force.
3Ease of operation
If conventional folding tables require a predetermined procedure with multiple operations for setup, then the table can be assembled, but the ease of operation decreases making setup not always easy
Solution Approach 1:
The biasing unit is pre-loaded with elastic force that automatically acts to separate the leg members when released. This preliminary action eliminates the need for manual adjustment or complex assembly procedures - users simply need to release the biasing unit and the legs automatically separate and position themselves.
Solution Approach 2:
The movably coupling unit allows the leg members to automatically move and position themselves relative to the tabletop during setup. This self-service mechanism eliminates the need for users to perform multiple precise alignment operations, reducing setup time and improving ease of operation.
4Adaptability or versatility
If conventional folding tables have numerous components for support and folding mechanisms, then the table has sufficient functionality, but the portability decreases making it not easy to carry around
Solution Approach 1:
The patent merges the folding mechanism with the biasing and coupling functions into compact integrated units. This allows the table to maintain full folding functionality while significantly reducing the number of discrete components that would add weight and bulk to the portable structure.

Function Achieved in This Case
The design enhances portability and ease of setup while maintaining rigidity, allowing for comfortable outdoor use by reducing the number of components and weight, making it easier to carry and use.
Implementation Method 1
a separation biasing unit that causes two leg members, disposed on the lower surface of the tabletop and positioned in opposition across an axis of pivot of the tabletop members, to move away from each other

AI summary
The invention relates to a folding table including: two tabletop members that are coupled to each other pivotably with one edges of the tabletop members serving as an axis, and are able to be folded; leg members that are disposed on a lower surface of a tabletop formed by unfolding the two tabletop members; a separation biasing unit that causes two leg members to move away from each other; and a movably coupling unit that couples the leg members to the tabletop members in such a manner as to be moveable from the one edge side to the other edge side. When the tabletop members are pivoted to unfold the tabletop, the separation biasing unit and the movably coupling unit cause the leg members to be unfolded along the lower surface of the tabletop.
