Modular Hardscape Assembly With Grooved Mechanical Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hardscape construction methods require on-site cement mixing and framework erection, necessitating labor-intensive processes and the use of distinct corner pieces for right-angle connections, lacking mechanical links between modular elements.
Innovation Solution
A modular building system featuring preformed hardscape structure sections with grooves and engagement portions, secured by connecting members and compression members, allowing for mortarless assembly and connection of upright wall panels to base slabs using dovetail or keyhole-shaped cross-sections, and support brackets with hooks for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If poured-in-place concrete is used to consolidate construction, then structural integrity is improved, but labor requirements and device complexity increase due to need for cement mixer and framework
Solution Approach 1:
The construction system is divided into discrete precast modules (base units, wall units, cap units) that can be manufactured separately and assembled on-site. Each module contains integrated connection features (recesses, protrusions, channels) that eliminate the need for separate frameworks and cement mixing equipment, while maintaining structural integrity through precise mechanical interlocking.
Solution Approach 2:
Connection features such as recesses, protrusions, and channels are pre-formed into the modules during manufacturing. This preliminary action eliminates the need for on-site framework erection and cement mixing, as the mechanical connection capabilities are already built into the components before assembly.
2Ease of operation
If distinct corner pieces are used for right-angle connections, then connection functionality is achieved, but device complexity and number of components increase
Solution Approach 1:
The modular units are designed with universal connection features that can accommodate various connection configurations including right-angle corners. The recess-protrusion-channels system can be arranged in different orientations and patterns on the same basic module type, allowing a single module design to serve multiple functions including corner, straight, and T-junction configurations.
3Strength
If mechanical links are added between modular elements, then connection strength is improved, but manufacturing complexity increases
Solution Approach 1:
The connection features (recesses, protrusions, channels) are merged directly into the module bodies during the precasting process. This integration eliminates the need for separate mechanical link components, as the connection capability is built into the modules themselves. The concrete casting process naturally forms these features without additional manufacturing steps.

AI summary
A modular building system, a method and a connecting assembly for building a hardscape structure, the modular building system comprising: a plurality of preformed hardscape structure sections including: a first hardscape structure section including a first section face and at least one first section groove defined in the first section face; a second hardscape structure section having a second section face and at least one second section groove defined in the second section face, the second hardscape structure section being disposed adjacent the first hardscape structure section such that the second section face is adjacent the first section face; and a connecting member having a first engagement portion for engaging one of the at least one first section groove and a second engagement portion for engaging one of the at least one second section groove to thereby secure together the first and second hardscape structure sections.
