Modular Roundabout Boards with Interlocking Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional modular roundabout systems require a large number of anchors for installation, making the process time-consuming and costly, and the filler boards are not effectively secured during vehicle traversals due to inadequate lateral loading resistance.
Innovation Solution
A modular roundabout system using interlocking connectors that allow perimeter and filler boards to be connected without being affixed to the ground, reducing the need for anchors and enhancing lateral loading resistance by forming a unitary structure with flexible hinge joints and spacers, allowing for easier transportation and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional modular roundabout systems use numerous ground anchors to secure boards, then the stability of the system is improved, but the installation time and cost increase significantly
Solution Approach 1:
The roundabout system is divided into modular boards that can be independently connected through edge-to-edge interlocking mechanisms. Each board segment can be installed separately and connected to adjacent segments, eliminating the need for numerous ground anchors while maintaining system stability through the interlocking connections between segments.
Solution Approach 2:
The connector integrates multiple functions into a single component: it provides structural connection between boards, resists lateral loading through its geometry, and eliminates the need for separate ground anchors. The connector merges the functions of joining, stabilizing, and lateral load resistance into one interlocking element.
2Strength
If traditional systems affix all boards to the ground surface with anchors, then lateral loading resistance is improved, but the complexity and cost of installation increase
Solution Approach 1:
The connector merges the functions of joining, stabilizing, and lateral load resistance into one interlocking element. This integrated connector eliminates the need for separate ground anchors and complex affixation systems, reducing installation complexity while maintaining lateral loading resistance through its geometric design and interlocking mechanism.
Solution Approach 2:
The interlocking connectors are designed to self-align and self-secure adjacent boards through their geometric features. The connectors automatically engage and lock into place, providing lateral loading resistance without requiring additional anchoring components or complex installation procedures, thereby reducing overall system complexity.
3Reliability
If perimeter boards are affixed to the ground with multiple anchors per board, then the security during vehicle traversals is improved, but the quantity of anchors and installation cost increase
Solution Approach 1:
The system segments the anchoring function from the board connection function. Instead of using multiple ground anchors per board, the lateral security function is transferred to the edge-to-edge interlocking connectors between adjacent boards. This segmentation eliminates the need for numerous ground anchors while maintaining security during vehicle traversals through the distributed network of interlocking connections.
Solution Approach 2:
The interlocking connector serves multiple functions: it connects adjacent boards, provides lateral loading resistance, and ensures security during vehicle traversals. This multi-functional connector replaces the need for multiple specialized components (ground anchors, fasteners, etc.), reducing the total quantity of substances required while maintaining reliability.
4Strength
If filler boards are connected with interlocking connectors forming a unitary structure, then the lateral loading resistance is improved, but the device complexity increases
Solution Approach 1:
The interlocking connectors are designed with uniform geometric features that can be replicated across all board connections. This homogeneity in connector design simplifies manufacturing and installation, reducing the perceived complexity despite the sophisticated interlocking mechanism. The consistent geometric pattern across all connectors provides lateral loading resistance while maintaining system simplicity.

AI summary
A modular roundabout or traffic calming system with interlocking connectors and a method of installation utilize a plurality of boards arranged in a pattern on a ground surface at an intersection of vehicle roadways, the pattern including one or both of a central island and a splitter island. At least some of the boards forming a perimeter of the pattern are affixed to the ground surface. At least some of the boards forming interior boards are interconnected at adjacent edges with connectors. The connectors can include a hinge joint so that the interconnected boards can be folded or rolled. A kit for a modular roundabout or traffic calming system is also provided.
