Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular vehicle barriers are cumbersome to erect, dismantle, and move, often requiring heavy machinery due to their weight and complexity, and lack flexibility in road width adaptation and easy manual operation.
Innovation Solution
A movable modular vehicle barrier composed of independent units with rotatable reclining bars, flexible belts, and auxiliary wheels, allowing for easy assembly, disassembly, and manual movement, with the ability to block or open road widths as needed, using a system of interconnected base bars, reclining bars, and a moving mechanism that enables one or two persons to operate it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multitude of modular units are connected together to form a vehicle barrier, then the barrier effectiveness and road width adaptability are improved, but the total weight increases to the point where it can no longer be handled by one or two persons
Solution Approach 1:
The barrier is divided into multiple independent modular units, each with its own moving system. This allows the barrier to be segmented into manageable portions that can be individually handled and positioned, resolving the contradiction between achieving sufficient barrier length for road coverage and maintaining manual operability.
Solution Approach 2:
Each modular unit incorporates a moving system with wheels and pivots that enable dynamic reconfiguration. The barrier can be easily assembled, disassembled, and repositioned by one or two persons despite the total weight, as the dynamic design allows for incremental manipulation of individual units rather than moving the entire structure at once.
2Strength
If the modular units are made heavy enough to effectively stop vehicles, then the vehicle stopping capability is improved, but the ease of manual operation and quick deployment deteriorates
Solution Approach 1:
The barrier's vehicle-stopping function is distributed across multiple modular units rather than concentrated in a single heavy structure. Each unit contributes to the overall stopping capability while remaining individually manageable, allowing the system to achieve strong vehicle interception capability without sacrificing manual operability.
Solution Approach 2:
The moving system incorporates pivots and wheeled mechanisms that enable rapid deployment and reconfiguration. Despite the weight necessary for effective vehicle stopping, the dynamic design allows one or two persons to quickly erect and dismantle the barrier, maintaining ease of operation.
3Reliability
If the barrier is designed as a fixed permanent structure, then the vehicle stopping reliability is improved, but the deployment time and cost increase significantly
Solution Approach 1:
The barrier uses modular units that can be quickly assembled and disassembled while maintaining reliable vehicle stopping capability. This segmented approach eliminates the need for time-consuming permanent installation while preserving the reliability needed to effectively intercept vehicles.
Solution Approach 2:
The moving system enables the barrier to be rapidly deployed and repositioned. The dynamic design with wheeled bases and pivoting components allows for quick erection and dismantling, dramatically reducing deployment time compared to fixed structures while maintaining adequate stopping reliability.
4Ease of operation
If auxiliary moving systems are added to enable manual movement, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The moving system is segmented and integrated into each modular unit rather than being a separate complex mechanism. Each unit has its own simple wheeled base and pivot points, distributing the moving function across multiple simple components rather than requiring one complex centralized system, thereby reducing overall device complexity.
Solution Approach 2:
The moving system components serve multiple functions: the wheels enable horizontal movement for deployment and repositioning, while the pivots allow for angular adjustment and configuration changes. This multi-functionality reduces the need for separate mechanisms, simplifying the overall device while maintaining ease of manual operation.

AI summary
A movable modular vehicle barrier (10) formed from at least two modular units (12). Each modular unit is foldable and comprising: a base bar (14), a reclining bar (16) hingedly connected to the base bar, a horizontal reclining bar (38) hingedly connected to the base bar, and a vertical reclining bar (42) hingedly connected to the reclining bar. In a folded position of the modular unit the base bar, the reclining bar, the horizontal reclining bar and the vertical reclining bar are substantially parallel to each other. In an operative position of the modular unit, the reclining bar forms with the base bar an internal angle that is not smaller than ninety degrees, the horizontal reclining bar is perpendicular to two adjacent base bars, and the vertical reclining bar is perpendicular to two adjacent reclining bars. The barrier includes a moving system for enabling manual movement of the barrier.
