Modular Cell Matrix for Load-Bearing Ground Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular cell designs for load-bearing features like roadways and walkways face challenges in accommodating tree root growth and utility lines while maintaining structural integrity, as they often require compacted soil for load-bearing support, which hinders root development, and have limitations in water collection and utility access.
Innovation Solution
A modular cell matrix system with aligned legs and interlinking members that share load, allowing for void spaces to be used as reservoirs or rooting areas, and providing easy access for utility lines, using a design that is strong enough to support loads without filling, with optional soil or filtration media, and accommodating various soil types and utility sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If compacted soil is used for load-bearing support, then the structural integrity of roadways and walkways is improved, but tree root development is hindered
Solution Approach 1:
The system divides the ground structure into separate functional layers: a compacted load-bearing layer for structural support and a non-compacted void space layer for root growth. The modular cells create discrete compartments that separate these conflicting requirements, allowing each layer to be optimized independently without compromising the other.
Solution Approach 2:
The invention transitions from a two-dimensional planar structure to a three-dimensional modular cell system with vertical layering. This adds the vertical dimension to separate load-bearing functions (lower layer) from root growth functions (upper void spaces), enabling both compacted and non-compacted environments to coexist in the same footprint.
2Strength
If modular cells with walls are used for structural support, then load-bearing capacity is improved, but water flow and utility access are restricted
Solution Approach 1:
The modular cell walls incorporate locally differentiated features: open sections or access points at specific locations for utility insertion and water flow, while maintaining solid wall structures in other areas for load-bearing support. This allows different parts of the same structure to serve different functions - structural integrity where needed and accessibility where required.
3Adaptability or versatility
If void spaces are created for rooting areas, then tree growth is improved, but load-bearing capacity is reduced
Solution Approach 1:
The system merges two previously separate structures into one integrated solution: the load-bearing structural frame and the rooting void spaces are combined into a single modular cell assembly. The structural walls and internal supports provide load-bearing capacity while simultaneously defining and protecting the void spaces for root growth, eliminating the need to choose between the two functions.
4Adaptability or versatility
If cells are stacked vertically without continuous load bearing members, then adaptability is improved, but structural rigidity deteriorates
Solution Approach 1:
The modular cells are pre-designed with integrated alignment features and load transfer mechanisms built into their structure. The walls and internal supports are configured in advance to ensure proper stacking alignment and continuous load paths, so that when cells are stacked vertically, the structural rigidity is automatically maintained without requiring additional field adjustments or complex assembly procedures.

AI summary
A modular cell that may be used with other cells to form a matrix under a load bearing feature, the cell being a single piece moulding that supports a compressive load placed thereon, the moulding including a void space defined within: a skirt shaped support member defining a substantially planar surface with an opening therein; and at least one leg integral to and extending from the support member. The cell further includes at least one separate linking member that releasably links together multiple cells to form a matrix of cells. The cells may be linked together vertically and/or horizontally. The cell and matrix include greater load bearing capacity and rigidity through aligned legs to carry the weight as well as interlinking members that act to share the load among the various cells. The design also requires less material hence is cheaper to produce. The void space is also easily accessed hence allowing for easy access, filling and laying of utility lines where needed.
