Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground stabilizing systems, such as the Dupont Plantex Groundgrid, face challenges in achieving structural stability when used with curable load-bearing materials like concrete, particularly in terms of supporting loads and resisting flexure loads.
Innovation Solution
A ground stabilization grid comprising polygonal cells formed by polymer walls with reinforcing ribs that engage opposing walls between 25% and 75% of the wall height, enhancing structural strength and stability when filled with load-bearing materials like concrete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional honeycomb grid structure is used for ground stabilization, then the grid can be easily manufactured and installed, but the structural strength and stability are insufficient when used with curable load-bearing materials like concrete
Solution Approach 1:
The grid is divided into multiple polygonal cells with reinforcing ribs that segment the structure into manageable units. Each cell with its reinforcing ribs acts as an independent load-bearing element, distributing stresses throughout the grid while maintaining overall structural integrity. This segmentation allows the grid to achieve high structural strength without requiring a monolithic complex design.
Solution Approach 2:
The grid combines polymer materials with reinforcing ribs to create a composite structure that leverages the advantages of both materials. The polymer provides flexibility and ease of installation, while the reinforcing ribs (engaging cell walls between 25%-75% of wall height) provide enhanced structural strength and stability, creating a composite system suitable for use with curable load-bearing materials.
2Ease of operation
If the grid structure is simplified for easier installation, then manufacturing and installation become easier, but the ability to resist flexure loads and support heavy loads deteriorates
Solution Approach 1:
The grid is divided into multiple polygonal cells with reinforcing ribs that segment the structure into manageable units. Each cell with its reinforcing ribs acts as an independent load-bearing element, distributing stresses throughout the grid while maintaining overall structural integrity. This segmentation allows the grid to achieve high structural strength without requiring a monolithic complex design.
Solution Approach 2:
The reinforcing ribs are strategically positioned to engage cell walls between 25%-75% of the wall height, providing localized reinforcement where flexure loads are most critical. This local quality enhancement allows the grid to resist heavy loads without requiring uniform thickening of all grid components, maintaining ease of installation while improving load resistance.
3Reliability
If reinforcing ribs are added to enhance structural stability, then load resistance improves, but the manufacturing complexity and cost increase
Solution Approach 1:
The grid is divided into multiple polygonal cells with reinforcing ribs that segment the structure into manageable units. Each cell with its reinforcing ribs acts as an independent load-bearing element, distributing stresses throughout the grid while maintaining overall structural integrity. This segmentation allows the grid to achieve high structural strength without requiring a monolithic complex design.
Solution Approach 2:
The reinforcing ribs are designed with specific geometric parameters (engaging cell walls between 25%-75% of wall height) that optimize structural stability while maintaining manufacturability. These parameter specifications provide clear manufacturing guidelines, enabling consistent production of reliable grid structures without excessive complexity.

AI summary
A ground stabilization grid which includes a series of polygonal shaped cells having “x” sides. The cells are formed by polymer walls having a wall height of between about 1″ and about 6″. Each cell shares a common wall section with at least two adjacent cells; and a majority of cells within the grid includes at least two reinforcing ribs extending across the cell to engage opposing walls of the cell. The reinforcing ribs are characterized by (i) engaging the cell walls between about 25% and about 75% of the wall height, and (ii) extending between different opposing walls of the cell.
