Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fixed car arrester is used, then it can intercept vehicles, but it lacks environmental adaptability and rapid deployment capability
Solution Approach 1:
The car arrester is divided into multiple detachable modules that can be quickly assembled and disassembled. Each module includes standardized connection interfaces (concave-convex structures with locking mechanisms) enabling rapid deployment without complex assembly procedures, directly resolving the contradiction between adaptability and deployment time.
Solution Approach 2:
The system transitions from a fixed static structure to a dynamic movable platform using wheeled assemblies with motors. The modular design allows the arrester to be transported to different locations and reconfigured based on environmental conditions, providing both environmental adaptability and rapid deployment capability.
2Loss of time
If a modular design is implemented for rapid deployment, then deployment speed improves, but device complexity increases
Solution Approach 1:
The system is segmented into standardized modules with uniform connection interfaces. The concave-convex locking mechanism with simple locking pieces provides intuitive assembly without requiring complex tools or procedures, reducing operational complexity despite the modular structure.
Solution Approach 2:
The modules are designed with universal connection interfaces that can accommodate different module types and configurations. The standardized concave-convex locking mechanism works across all modules, simplifying the assembly process and reducing the complexity burden of modularity.
3Loss of time
If the arrester is made movable with traveling assemblies, then rapid deployment is achieved, but reliability during interception may be compromised
Solution Approach 1:
The arrester is deployed to the optimal interception position before the vehicle arrives. The movable wheeled assembly allows advance positioning, and once in place, the system is stabilized for reliable interception. The preliminary deployment action separates the movement function from the interception function, maintaining reliability during the actual interception event.

AI summary
A movable car arrester module and a car arrester are disclosed. The movable car arrester module includes an L-shaped support including a base and a vertical column connected to the base. At least one connecting assembly is arranged on the L-shaped support and is used for assembling two adjacent car arrester modules of the same structure into the car arrester. At least one traveling assembly is arranged on the L-shaped support and is mounted on the base. A plurality of car arrester modules are detachably assembled to form the array-type modular car arrester so that the police can intercept and control a vehicle in a short time, and the work efficiency is improved.
