Retractable Lateral Tire Puncture Device for Police Pursuits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle disablement devices are unsafe for police officers as they require manual deployment, are not mobile, and cannot be used effectively on uneven surfaces, leading to high costs and risks during high-speed pursuits, resulting in damage and loss of life.
Innovation Solution
A retractable, laterally deployable tire puncture device that can be activated from within a police vehicle, using a telescoping assembly and pneumatic system to extend a spike strip transversely across the path of a fleeing vehicle, allowing safe and automatic deployment without requiring the officer to exit the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual deployment of tire puncture devices is used, then the device can be deployed, but the police officer is put in harm's way and must exit the vehicle
Solution Approach 1:
The device is designed to deploy automatically through a telescoping mechanism that extends the spike strip laterally without requiring manual handling by the officer. The system serves itself by using the vehicle's motion and integrated pneumatic actuators to deploy the disablement device, eliminating the need for officer exposure.
Solution Approach 2:
A telescoping assembly with pneumatic actuators serves as an intermediary mechanism between the officer's control input and the actual deployment of the spike strip. This intermediary system translates remote control signals into automatic deployment actions, protecting the officer from direct exposure.
2Adaptability or versatility
If traditional tire puncture devices are used, then vehicle disablement can be achieved, but the devices are not mobile and cannot adapt to uneven surfaces
Solution Approach 1:
The device transitions from a static, fixed configuration to a dynamic, movable system. The telescoping assembly allows the spike strip to extend and retract, adapting its position and orientation to match the vehicle's motion and road surface conditions, thereby maintaining reliability across varying environments.
Solution Approach 2:
The disablement device is divided into segmented components including the telescoping assembly, pneumatic actuators, and modular spike strip sections. This segmentation allows each component to independently adapt to road surface variations while maintaining overall system functionality.
3Productivity
If police pursue fleeing vehicles, then justice can be served, but damage and loss of life increase due to lack of disablement capability
Solution Approach 1:
The device enables preliminary disablement action by deploying the spike strip during the pursuit to puncture the fleeing vehicle's tires before the pursuit reaches its climax. This preliminary intervention stops the pursuit early, preventing the damage and loss of life that would otherwise occur.
Solution Approach 2:
The device converts the harmful element of tire puncture into a beneficial outcome by using the puncture mechanism not to cause damage, but to safely disable the fleeing vehicle and end the pursuit, thereby reducing overall harm to officers, suspects, and bystanders.
