Engineering Contradiction Analysis
1Stability of the object's composition
If wires are used to form a three-dimensional wire structure, then the structure can be created, but the wires lack self-supporting capacity and require additional connecting elements for stabilization
Solution Approach 1:
The patent applies helical curvature to the wires, transforming them from straight linear elements into curved helical structures. This curvature provides inherent mechanical stability and self-supporting capacity, eliminating the need for additional connecting elements. The helical shape allows the wires to interlock and support each other through their curved geometry alone.
Solution Approach 2:
The patent creates a dynamic wire structure where helical wires can move and adjust relative to each other, providing adaptability and self-supporting capacity. The helical configuration allows for controlled movement and deformation while maintaining structural integrity, enabling the structure to stabilize itself without additional connectors.
2Shape
If wires extend diagonally through the entire three-dimensional wire structure, then the structure can be formed, but the length and quantity of wires increase production cost and time
Solution Approach 1:
The patent segments the wire structure into modular helical units that can be produced independently and then assembled. Instead of using long diagonal wires spanning the entire structure, the structure is divided into smaller helical wire segments that repeat in a pattern, reducing the length of individual wires and simplifying production.
Solution Approach 2:
The patent transitions from linear wire extensions to three-dimensional helical configurations. By utilizing the helical form that occupies three-dimensional space efficiently, the structure achieves its shape requirements without needing excessively long wires, as the helical path provides structural function within a compact volume.
3Strength
If wires are bonded, soldered or welded at intersection points to stabilize the structure, then the structure gains rigidity, but material and production costs increase
Solution Approach 1:
The patent employs helical wires that provide self-supporting capacity through their curved geometry, allowing the structure to stabilize itself without requiring external bonding, soldering, or welding processes. The helical configuration enables the wires to interlock and support each other inherently, eliminating the need for additional manufacturing steps and reducing production costs.
4Strength
If the frame is designed with wires extending in all directions, then the structure achieves rigidity in all directions, but the degree of rigidity is not optimum for diverse applications
Solution Approach 1:
The patent applies helical configuration locally to the wires, giving each wire segment specific curved properties that provide directional support. This local helical quality allows the structure to achieve rigidity where needed while maintaining adaptability, as the helical wires can be arranged in different patterns and orientations to suit diverse application requirements.
