Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reinforcement methods for large structures like road embankments, such as using metallic grids or high-strength fabrics, often fail to effectively anchor the reinforcement materials to the ground, leading to destabilization under traffic loads and potential damage from sinking or deformation.
Innovation Solution
A sheet-like element with a lattice-like configuration featuring main wires with a quadrangular cross-section and sharp edges, providing increased friction and anchoring capabilities, is used to reinforce, separate, and drain large structures, allowing for greater load-bearing capacity without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional reinforcement methods (metallic grids, plastic nets, high-strength fabrics) are used, then the structure provides basic reinforcement, but the anchoring effectiveness is insufficient leading to destabilization under traffic loads
Solution Approach 1:
The invention applies different wire thicknesses at different locations within the lattice structure. Main wires have a thickness of at least 3mm while transverse wires have a thickness of at most 1mm. This local differentiation creates enhanced friction and mechanical interlocking with the surrounding soil or filler material at critical anchoring points, thereby improving anchoring effectiveness without compromising overall load-bearing capacity
Solution Approach 2:
The invention changes the geometric parameters of the lattice structure by specifying that the spacing between main wires is between 50-100mm while the spacing between transverse wires is between 20-50mm. This parameter optimization enhances the surface area contact with filler material and improves mechanical interlocking, thereby resolving the contradiction between anchoring effectiveness and load-bearing capacity
2Ease of operation
If the sheet-like element uses uniform thin wires for flexibility, then ease of installation is improved, but friction with filler material is insufficient reducing anchoring stability
Solution Approach 1:
The lattice structure employs non-uniform wire thicknesses where main wires (≥3mm) provide high friction and anchoring stability at critical locations, while transverse wires (≤1mm) maintain flexibility and ease of installation. This local quality differentiation resolves the contradiction between installation ease and anchoring stability
Solution Approach 2:
The invention transitions from a two-dimensional planar net to a three-dimensional lattice structure with vertical spacing between wires. This dimensional change creates additional surface area for friction with filler material while maintaining the flexibility needed for easy installation, thereby resolving the contradiction between installation ease and anchoring stability
3Reliability
If the lattice spacing is reduced to improve anchoring, then friction with filler material increases, but the sheet-like element becomes more complex and harder to manufacture
Solution Approach 1:
The invention applies different spacing intervals to different wire orientations: main wire spacing of 50-100mm and transverse wire spacing of 20-50mm. This local quality approach optimizes anchoring strength in critical directions while maintaining manufacturability by not uniformly reducing all spacing, thereby resolving the contradiction between anchoring strength and structural complexity
Solution Approach 2:
The invention optimizes specific geometric parameters of the lattice structure, setting main wire spacing at 50-100mm and transverse wire spacing at 20-50mm, with main wire thickness ≥3mm and transverse wire thickness ≤1mm. These parameter changes achieve optimal anchoring strength while maintaining reasonable structural complexity for manufacturing

AI summary
A sheet-like element for reinforcing, separating and draining large structures such as road embankments. The element includes a sheet-like body which has a lattice like configuration with main wires and transverse wires stretched respectively along two mutually substantially perpendicular directions and that intersect in nodes. The main extend in the extrusion direction of the blank. The main wires have an upper rim and a pair of substantially vertical lateral walls extending downwardly from the upper rim at opposite ends of said upper rim. The main wires have a lower rim in regions remote from the nodes. The main wires have a lower portion in regions at the nodes which converge with the transverse wires.
