Clamshell Tire Lock With Puncture Spikes for Trailer Immobilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire lock systems are inefficient in preventing the movement of vehicles, as they can be overcome with enough force, leading to damage but not effectively restricting movement, especially for larger vehicles.
Innovation Solution
A tire lock system comprising an outer beam and an inner beam with spikes attached, where the beams are secured around the tire to prevent rotation, and if the tire attempts to rotate, the spikes puncture the tire, effectively immobilizing the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large bar is secured under the tire to restrict rotation, then the tire rotation is restricted, but the tire can still rotate with enough force causing vehicle movement and damage
Solution Approach 1:
The patent applies preliminary action by pre-installing spikes on the tire lock device before it is placed on the tire. These spikes are positioned to contact the tire tread in advance, so that if the tire attempts to rotate, the spikes immediately puncture the tire rather than allowing rotation to occur. This preventive puncture mechanism ensures the tire is immobilized before movement can happen.
Solution Approach 2:
The patent converts the harmful effect of tire rotation into a beneficial immobilization mechanism. Instead of simply resisting rotation with friction or mechanical blocks, the device uses the attempted rotation itself to drive spikes into the tire, causing puncture and flat tire. The harmful force applied to rotate the tire becomes the mechanism that secures the vehicle by destroying the tire's ability to rotate.
2Device complexity
If a large bar is used to secure the tire, then the structure is simple, but it is not strong enough to prevent movement of larger vehicles
Solution Approach 1:
The patent segments the tire lock device into multiple functional components: an outer beam that contacts the tire outer surface, an inner beam that contacts the tire inner surface, and multiple spikes distributed along the beams. This segmentation allows each component to perform its specific function - the beams provide structural framework and contact points, while the spikes provide the puncture mechanism. The segmented design increases effectiveness without significantly increasing overall complexity.
Solution Approach 2:
The patent employs composite construction by combining different materials with complementary properties. The beams are made from high-strength materials to resist bending and breaking forces from large vehicles, while the spikes are made from extremely hard, wear-resistant materials to ensure they can puncture various tire types. This composite approach creates a device that is both structurally strong and effectively puncturing.
3Object-affected harmful factors
If spikes are added to puncture the tire, then movement is effectively prevented, but the device complexity increases
Solution Approach 1:
The patent merges the structural support function and the puncture function into a single integrated device. The beams that provide the structural framework also serve as the mounting structure for the spikes, eliminating the need for separate mounting mechanisms. The spikes are directly attached to the beams at strategic positions, combining the mechanical support element with the immobilization element into one unified structure that reduces overall device complexity.

AI summary
A tire lock system prevents the movement of a trailer or vehicle once attached. A clamshell-style arms are attached to the inside and outside of a tire. Spikes on the arms are placed so that if the tire is rotated the spikes puncture the tire. The arms are reinforced and strengthen to prevent cutting, pulling, removal, or damage to the arms. The arms are held in place by a lock that is unique to each so that removal requires a special tool.
