Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork designs for creating concrete matrices are complex, costly, and lack sufficient structural strength, particularly when subjected to compressive loads, and they often require multiple parts for assembly.
Innovation Solution
A formwork design configured to receive and retain concrete within an internal void space while maintaining a concrete-free external void space, featuring a frame with lateral supports and tapering legs that connect via vertical and horizontal couplings, allowing for efficient assembly and high compressive strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing plastic art cells are used for structural support, then void space is provided for applications like tree root growth or water reservoir, but the structural strength and compressive load bearing capability are insufficient
Solution Approach 1:
The patent combines plastic formwork structure with concrete infill to create a composite cellular structure. The plastic frame provides structural integrity and void space, while the concrete infill provides high compressive strength. This composite approach resolves the contradiction by achieving high strength without increasing structural complexity, as the concrete simply fills the existing void space of the plastic cells.
2Ease of operation
If multiple separate parts like sockets and plates are used in formwork assembly, then coupling cells is possible, but manufacturing cost increases and assembly becomes slower
Solution Approach 1:
The patent integrates the coupling mechanism directly into the leg structure itself, eliminating the need for separate sockets and plates. The legs are designed with integrated coupling features that allow direct connection between cells. This merging of functions reduces the number of parts, simplifies assembly, and lowers manufacturing cost while maintaining ease of operation.
Solution Approach 2:
The leg structure is designed to be self-coupling, where the leg itself provides both the structural support and the coupling mechanism. The tapered design with integrated features allows legs to self-align and self-couple without requiring separate coupling components, making the assembly process simpler and faster.
3Stability of the object's composition
If plastic formwork is used, then assembly is simplified, but elastic deflection occurs under load which is problematic when coupled with brittle materials
Solution Approach 1:
The patent creates a composite structure where the plastic formwork provides structural stability and the concrete infill provides rigidity. The concrete, being a brittle material with high compressive strength, compensates for the elastic deflection characteristics of plastic. This composite material approach resolves the contradiction by combining materials with complementary properties to achieve overall structural stability.

AI summary
Formwork, matrices, concrete matrices and methods of manufacture are described. The formwork may be configured to receive and retain concrete within an internal void space and has a concrete free external void space. Also described is a concrete matrix formed using the formwork and related methods of manufacture of a formwork matrix and formwork. The formwork itself and matrices formed from the formwork may have a degree of compressive strength. With concrete poured and set into the formwork, the resulting concrete matrix has a very high compressive strength and forms a structural matrix on which a hardscape or load may be placed. The above formwork, matrices, and methods reduces the number of parts needed to form a formwork or matrix and may facilitate snap fit design and installation and hence the ability to assemble the matrix toolessly.
