Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to balance the need for load-bearing support for pavements and walkways with the requirement for tree root growth, often compromising either structural integrity or root development, and face challenges in vertical stability, lateral connection, and efficient storage/transport of modular cell frames.
Innovation Solution
A modulated cell with a top plate featuring vertical integral legs, snap-fit fastening, and interlocking means for lateral connection, allowing cells to be stacked and joined without external attachments, providing both load-bearing support and root accommodation with enhanced stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rectangular crate type structure with open spaces is used to accommodate tree root network, then root growth space is improved, but vertical stability of the frame structure deteriorates
Solution Approach 1:
The patent incorporates pre-designed reinforcement elements and bracing structures within the cell framework before assembly. These preliminary structural enhancements provide vertical stability to the open-space design, allowing the structure to maintain its load-bearing capacity while accommodating tree root networks without requiring additional stabilization during or after assembly.
Solution Approach 2:
The patent employs composite construction techniques combining different materials with complementary properties - such as reinforced polymers, metal alloys, or hybrid material systems - to create cell structures that simultaneously provide the open spaces needed for root growth and the structural strength required for vertical stability and load-bearing performance.
2Adaptability or versatility
If the cell frame is made up of several independent components (base, top plate, fastening means), then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple independent components (base, top plate, fastening means) into unified, multi-functional elements. For example, the top plate incorporates integrated fastening mechanisms and alignment features directly molded or formed as part of the single component, eliminating the need for separate fasteners and alignment devices, thereby reducing overall component count while maintaining modular adaptability.
Solution Approach 2:
The patent designs each cell component to perform multiple functions simultaneously - such as structural support, connection, alignment, and stabilization - allowing fewer components to achieve the same level of complexity and adaptability that would otherwise require numerous specialized parts, thus simplifying the overall device while preserving modular versatility.
3Adaptability or versatility
If multiple individual components make up the cell frame, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent designs the cell components with nesting capabilities, allowing smaller components to be inserted within larger ones during storage and transport. For example, bases can be nested within cell bodies, and top plates can be stacked within or alongside other components, dramatically reducing the volume required for packaging and transportation while maintaining the modular component structure for easy assembly at the installation site.
4Strength
If further posts and beams are added to reduce cell frame dimensions, then load bearing capacity is improved, but root network accommodation deteriorates
Solution Approach 1:
The patent applies reinforcement elements and structural enhancements selectively at specific locations within the cell frame where load-bearing demands are highest, rather than uniformly throughout the entire structure. This localized strengthening approach provides the necessary load-bearing capacity while preserving maximum open space in the root network accommodation zones, avoiding unnecessary material addition that would encroach on root growth areas.

AI summary
A modulated cell adapted to form a structural frame of said cells for supporting a load bearing feature of a roadway, pavement or walkway while at the same time providing a rooting area within the structural frame for a tree root network. The cell has a main body with vertical integral legs with a top plate having regions upon its upper skirting for a snap fit fastening arrangement for receiving the ends of said legs of a resting cell thereupon said top plate to mount one cell vertically upon another and the top plate has its peripheral edge an interlocking means for laterally joining together with adjacent cells so the modulated cells can be mounted vertically and laterally one upon the other and side by side.
