Modular Barrier Transport Vehicle for Confined Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for transporting roadway barriers are cumbersome and unsuitable for confined spaces due to their large size and lack of flexibility in configuration and operation.
Innovation Solution
A barrier transport vehicle system comprising interconnected modules that can lift and transport barrier modules by engaging with their inner surfaces, allowing for reconfiguration and efficient movement within restricted areas, using steerable wheels or caterpillar treads and guidance tracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If large barrier transfer machines are used to transport roadway barriers, then the barriers can be moved from one location to another, but the machines are not suitable for confined or restricted operating situations
Solution Approach 1:
The barrier transport system is divided into multiple modular components including a leading module, intermediate modules, and a trailing module. Each module can independently navigate through barrier passageways, allowing the system to operate in confined spaces while maintaining the capability to transport full-length barriers.
Solution Approach 2:
The transport vehicle modules are designed to pass through the hollow interior cavities of the barrier modules themselves. The leading module enters first, followed by intermediate modules, and finally the trailing module, creating a nested configuration where the transport system is temporarily housed within the barrier structure during insertion.
2Ease of operation
If manual control or infrastructure modifications are used to operate barrier transfer machines, then the machines can be steered, but the operation becomes complex and requires additional infrastructure
Solution Approach 1:
Each module of the transport vehicle is equipped with its own propulsion system and steering capabilities. The modules can autonomously navigate through the barrier passageways and position themselves without requiring external control infrastructure such as guide wires or magnetic tape, significantly simplifying the operation.
3Adaptability or versatility
If wheels are incorporated in barrier modules to allow towing, then the barrier can be moved and reconfigured, but the wheels must be retracted to prevent dislodgement by vehicle impact
Solution Approach 1:
The transport system uses retractable support members that can dynamically extend to provide stabilization when needed and retract when towing or reconfiguration is required. This dynamic adjustment allows the barrier to transition between stable installation mode and mobile transport mode without permanent structural modifications.
