Extendable Tire Spiker with Spring-Loaded Hinge for Safe Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Law enforcement officers face danger during traffic stops due to the risk of high-speed chases, as existing tire immobilization devices are bulky, require dangerous manual deployment, and fail to provide adequate protection, necessitating a small, lightweight, and easily deployable solution to prevent vehicle fleeing.
Innovation Solution
A tire spiker with a U-shaped frame and spring-loaded hinges that can be quickly deployed to encase and expose spikes for tire puncturing, allowing for one-handed operation and maintaining officer safety by positioning spikes around the tire without bending or diverting attention from the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tire immobilization devices (boots or puncture strips) are used, then the tire can be disabled, but the officer must get under or in front of the vehicle which places the officer in danger
Solution Approach 1:
The tire spiker device serves as an intermediary tool that allows the officer to disable the tire from a safe distance. The extendable handle acts as the intermediary mechanism, enabling the officer to reach and deploy spikes into the tire without needing to approach the vehicle closely or get under it, thus maintaining effectiveness while eliminating the safety risk.
2Reliability
If bulky tire deflating apparatus are used, then tire puncturing capability is provided, but the device fails to provide protection to the officer during transport and deployment
Solution Approach 1:
The spikes are nested within the handle structure during transport and storage. The handle contains hollow chambers or compartments that hold the spikes in a retracted position, protecting both the spikes and the officer. When deployed, the spikes extend outward from the handle to perform their puncturing function, transitioning from a protected nested state to an active deployed state.
3Manufacturing precision
If the tire spiker requires two-handed operation or bending over for deployment, then precise placement can be achieved, but the officer must divert attention from the driver increasing danger
Solution Approach 1:
The tire spiker is designed with self-aligning features that allow it to be deployed with minimal manual manipulation. The extendable handle incorporates guides or alignment mechanisms that automatically position the spikes correctly as they extend, eliminating the need for the officer to bend over or use both hands for precise placement. The officer simply needs to point the device at the tire and activate deployment.
4Volume of moving object
If the device is made compact for easy storage, then portability is improved, but deployment mechanism complexity increases
Solution Approach 1:
The tire spiker employs a dynamic deployment mechanism where the handle transitions from a compact retracted state to an extended deployed state. This dynamic transformation allows the device to maintain a small footprint for storage while providing full functionality when needed. The mechanism uses spring-loaded or telescoping components that automatically extend upon activation, reducing the need for complex manual assembly or deployment procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tire spiker effectively prevents vehicle movement by puncturing tires with exposed spikes, enhancing officer safety by allowing deployment without putting them in harm's way, thus reducing the risk of injury or death during high-speed chases.
Implementation Method 1
The spring loaded hinge may be adapted to urge the two L-shaped arms into the deployed configuration

AI summary
The tire spiker with an extendable handle may comprise a pair of spike portions pivotally connected by a spring loaded hinge adapted to hold the spike portions in a deployed U-Shaped configuration to be deployed in front of and behind a tire in a traffic stop. An extendable handle on the frame may have a release button adapted to release a latch holding the spike portions together in a carry configuration. The spring loaded hinge urges the spike portions in a spaced, parallel orientation for surrounding a tire in a deployed configuration. The tire spiker with extendable handle is moved to a position whereby the two spike portions are in front of and behind a tire. The spike portions have upward oriented spikes adapted to puncture the tire if the tire rolls forward or backwards.
