Modular Traffic Calming Device Interlocking Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic calming devices, such as speed bumps and humps, are difficult to install and remove, and they often lack a consistent aesthetic appearance and stable profile.
Innovation Solution
A modular traffic calming device composed of interconnected, lightweight, rectangular modules with complementary interlocking and non-interlocking connections allows for easy assembly and disassembly, enabling flexible installation and removal without fully closing roads, using standardized shapes and materials like recycled plastic and rubber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional traffic calming devices are built from asphalt or concrete, then they provide structural strength and durability, but they become difficult to install and remove
Solution Approach 1:
The traffic calming device is divided into multiple separate modules that can be individually handled and installed. Each module can be independently positioned and connected to adjacent modules, allowing for easier installation and removal compared to conventional monolithic asphalt or concrete structures.
Solution Approach 2:
The device uses composite construction combining rigid structural elements with interlocking connection mechanisms. The modules incorporate both structural components for strength and connection features for ease of assembly, creating a hybrid system that achieves both durability and installability.
2Stability of the object's composition
If conventional traffic calming devices are built from asphalt or concrete, then they provide structural stability, but they cannot easily maintain a consistent profile during their lifetime
Solution Approach 1:
By segmenting the device into standardized modules with precise manufacturing tolerances, each module contributes to the overall consistent profile. The modular design allows for quality control during manufacturing while maintaining ease of installation through simple interconnections.
Solution Approach 2:
The modular design enables precise control of geometric parameters such as height, slope, and curvature through standardized module dimensions. This ensures profile consistency across the entire device while maintaining ease of installation through repeatable module configurations.
3Area of stationary object
If traffic calming devices use a single large structure, then they provide continuous coverage, but they require heavy equipment for handling and installation
Solution Approach 1:
The large coverage area is achieved by assembling multiple smaller modular units rather than using a single large structure. This segmentation allows each module to be handled with lighter equipment while the collective assembly provides the required continuous coverage.
Solution Approach 2:
Multiple individual modules are combined to form a continuous traffic calming structure. The interlocking connections between modules create a unified appearance and function while retaining the handling advantages of smaller individual components.

AI summary
The modular traffic calming device comprises a plurality of substantially rectangular modules. Each module is connectable to one or more adjacent modules using a complementary interlocking connection across a first of the side faces of modules, and using a complementary non-interlocking connection across a second of the side faces of the modules.
