Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threads of molten material are deposited on a metal grid and cooled, then a ground covering structure is formed, but the threads do not adhere fully to the metal grid and may become detached during use
Solution Approach 1:
The patent changes the physical parameters of the metal grid surface by creating an uneven profile with peaks and valleys. This surface modification alters how the molten material interacts with the grid, allowing the material to flow into valleys and mechanically interlock with peaks, thereby improving adhesion and preventing thread detachment during use.
Solution Approach 2:
The patent applies preliminary action by pre-forming the metal grid with an uneven surface profile before depositing the molten material. This pre-prepared surface structure ensures that when the material is deposited, it automatically achieves proper mechanical interlocking and adhesion without requiring additional bonding steps.
2Strength
If a metal grid is used as reinforcing member, then high mechanical strength is achieved, but the threads may detach during use
Solution Approach 1:
The patent modifies the surface geometry parameter of the metal grid by creating an uneven profile with specific peak and valley dimensions. This parameter change maintains the inherent high mechanical strength of the metal grid while adding surface features that enable reliable thread retention through mechanical interlocking.
3Ease of manufacture
If the production process uses a simple cooling method, then production cost is reduced, but thread adhesion to the grid is insufficient
Solution Approach 1:
The patent achieves improved thread adhesion through parameter changes in the metal grid surface geometry rather than through complex cooling methods. The uneven surface profile with controlled peak and valley dimensions allows the molten material to mechanically interlock during the existing cooling process, maintaining production simplicity while significantly improving adhesion reliability.

AI summary
A production plant for a ground covering structure (6) comprises a plant inlet zone and a plant outlet zone for a grid reinforcing member (10). The plant further comprises movement means (4) designed in operation to move the grid reinforcing member (10) along a predetermined path from the inlet zone to the outlet zone, supply means (11) for the supply of plastics material in the fluid state in the form of threads (7) to the reinforcing member (10) disposed along the predetermined path, and cooling means (2, 3) for cooling the plastics material in the form of threads (7) which are tangled on the grid reinforcing structure. The inlet zone and the outlet zone are disposed opposite one another along the predetermined path with respect to the supply means.
