Tyre Puncture Device with Rupture Zone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for stopping fleeing vehicles, such as the STOPSTICK® range, pose risks to handlers due to the need for close proximity and potential misfire during deployment, and existing systems are either non-portable or difficult to reload quickly.
Innovation Solution
A tire puncture device with a puncture module having a carrier plate for grouping puncture members, positioned by a support with a privileged rupture zone that allows easy detachment and quick reloading, ensuring safety and efficiency in stopping vehicles without exposing handlers to danger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If triangular-section puncture modules are thrown in front of a fleeing vehicle, then the vehicle can be stopped, but the operator is exposed to danger due to close proximity
Solution Approach 1:
The device is divided into modular components: multiple puncture modules can be independently positioned on the support structure, allowing selective deployment and reducing the need for operators to be in dangerous close proximity during deployment
Solution Approach 2:
A support structure acts as an intermediary between the operator and the puncture modules, enabling remote positioning and deployment of the modules without requiring the operator to be close to the vehicle path
2Manufacturing precision
If puncture modules are pulled along using a line to position them near tires, then positioning accuracy is improved, but deployment time increases and operators remain exposed to danger
Solution Approach 1:
Multiple puncture modules are pre-positioned on the support structure at optimal locations before deployment, eliminating the need for time-consuming pulling and positioning operations during the actual stopping sequence
Solution Approach 2:
Multiple puncture modules are combined into a single integrated support structure, allowing simultaneous deployment of multiple modules in one action rather than sequential positioning operations
3Reliability
If fixed systems are used to stop fleeing vehicles, then stopping reliability is improved, but portability and ease of replacement are reduced
Solution Approach 1:
The support structure is designed to transition from a stationary fixed state during operation to a movable portable state for deployment and relocation, combining the reliability of fixed systems with the flexibility of portable systems
Solution Approach 2:
The system is segmented into modular components that can be easily assembled and disassembled, allowing rapid deployment and replacement while maintaining the structural integrity needed for reliable vehicle stopping
4Reliability
If multiple puncture elements are grouped closely together, then puncture effectiveness is improved, but the risk of device projection and handler injury increases
Solution Approach 1:
The puncture elements are arranged with varying spacing patterns: closely spaced in areas requiring high puncture effectiveness while maintaining adequate separation from the support structure edges to prevent premature projection during deployment
