Portable Tyre Escape Device with Spring-Loaded Jacking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-skid chains and self-rescue equipment are cumbersome, time-consuming to mount and dismount, and ineffective in preventing tyre skidding and trapping on slippery or icy surfaces, leading to frequent accidents and economic losses.
Innovation Solution
A portable escape device comprising a support post, clamping device, and jacking device that can be quickly mounted on a trapped tyre, allowing the tyre to be jacked out of a pit using a spring-loaded mechanism and high-strength nylon strap for secure clamping and lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If anti-skid chains are mounted on tyres, then frictional force with the road surface is increased and anti-skid role is played, but the device becomes heavy and causes severe pavement destruction
Solution Approach 1:
The patent uses a flexible anti-skid cover made of rubber or plastic material that can be wrapped around the tyre. This thin film structure provides the necessary frictional force to prevent skidding while being significantly lighter than traditional iron chains, thus resolving the contradiction between increasing frictional force and reducing weight.
2Reliability
If anti-skid chains are used, then anti-skid effect is achieved, but mounting and dismounting is complex and consumes great deal of time and labor
Solution Approach 1:
The anti-skid device is divided into modular components including the anti-skid cover, fastening mechanism, and support structures. This segmentation allows for quick assembly and disassembly by simply wrapping the cover around the tyre and securing it with fasteners, dramatically reducing the time and labor required compared to traditional chain installation while maintaining reliable anti-skid performance.
3Reliability
If anti-skid chains are mounted, then running safety performance is improved, but tyre wear increases and pavement destruction is severe
Solution Approach 1:
The patent employs a flexible rubber or plastic cover that conforms to the tyre surface, providing the necessary friction enhancement without the rigid, abrasive nature of metal chains. This flexible material significantly reduces tyre wear and minimizes pavement damage while maintaining improved running safety performance.
4Reliability
If self-rescue equipment is used, then escape from trapped tyre is possible, but the equipment is complex to assemble and disassemble
Solution Approach 1:
The self-rescue device incorporates a jack mechanism with modular components that can be quickly assembled and disassembled. The segmented design allows users to rapidly set up the jack under the vehicle and secure the anti-skid cover without requiring complex assembly procedures, thereby maintaining reliable self-rescue capability while significantly improving ease of operation.
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 device enables rapid and reliable self-rescue from tyre traps, reducing accident risk and saving time and labor, while being easy to carry and assemble, even in harsh weather conditions.
Implementation Method 1
an elastic element sheathing the bolt... the elastic element is a spring and is located between the jacking head and the support plate
Implementation Method 2
The inner surface of the claw which is in contact with the tyre portion is provided with a rubber liner... increasing frictional force

AI summary
A portable escape device is provided for self-rescue in the case of an auto tyre being trapped in a pit. The portable escape device includes support posts, a clamping device fitted to the support posts, and a jacking device fitted to the clamping device. The support posts are fixedly mounted onto spokes. The clamping device clamps an auto tyre. The jacking device protrudes and extends out of a top face of a tyre portion. The portable escape device can release the trapped auto tyre and perform self-rescue fast and reliably, and it is convenient to carry.
