Segmented Ice and Snow Cleats for Tire Traction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire chains are heavy, dirty, prone to rust, entangled, and difficult to install, especially in adverse weather conditions, making them cumbersome and inefficient for icy and snowy roads.
Innovation Solution
The 'Ice and Snow Cleats' system consists of lightweight, stackable, and easily cleanable components made from materials like hard rubber, fiberglass, and aluminum, with adjustable bungee cords and chain welts, eliminating hooks to prevent entanglement and allowing for quick assembly and disassembly, weighing no more than 5 pounds per part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional steel tire chains are used, then traction on icy and snowy roads is improved, but weight increases significantly (25-50 pounds per set)
Solution Approach 1:
The tire chain system is divided into multiple separate components: individual chain segments, connecting links, and tensioning mechanisms. This segmentation allows the chains to be lighter individually while maintaining collective functionality, and enables partial installation or removal without handling the entire heavy assembly at once.
Solution Approach 2:
The chain links are designed to nest within each other when not in use, with smaller links fitting inside larger ones. This nesting capability reduces the effective volume and weight perception during storage and transport, while maintaining the full chain structure when deployed for traction.
2Reliability
If steel tire chains are used, then traction is improved, but they become dirty with road grime and rust
Solution Approach 1:
The tire chains incorporate composite material construction, combining steel elements with rust-resistant coatings or alternative materials such as coated wires or synthetic fibers. This composite approach maintains the strength and traction properties of steel while adding protective layers that prevent rust and reduce adhesion of road grime.
Solution Approach 2:
The design accepts that some contamination will occur but converts it into a benefit by creating a lubricated effect where accumulated grime reduces friction between chain links, preventing entanglement and making the chains easier to manipulate during installation and removal.
3Reliability
If traditional tire chains with hooks are used, then traction is improved, but the hooks become entangled and difficult to manage
Solution Approach 1:
Instead of using traditional hooks that protrude outward and can easily catch on each other, the connection mechanism uses inverted designs such as recessed coupling points, snap-fit connections, or magnetic attachments where the connecting elements are contained within the chain structure rather than extending outward, preventing entanglement during handling.
Solution Approach 2:
An intermediary connection element is introduced between the chain links and tensioning components. This mediator component serves as a dedicated attachment point that simplifies the connection process, allowing for tool-free or minimal-tool assembly and disassembly without the complexity of traditional hook-and-eye systems.
4Reliability
If tire chains are installed in adverse weather conditions, then traction is improved, but the installation process becomes more difficult and time-consuming
Solution Approach 1:
The chain segments, connecting links, and tensioning components are pre-assembled into modular units before reaching the vehicle. This preliminary preparation allows the installation process to involve simply attaching pre-configured modules to the tires rather than assembling individual links in cold, adverse conditions, significantly reducing installation time and complexity.
Solution Approach 2:
The chain system incorporates dynamic tensioning mechanisms that automatically adjust to tire pressure changes and road conditions during installation and operation. This dynamic adjustment eliminates the need for precise manual tensioning in adverse weather, as the system self-regulates to maintain optimal traction.

AI summary
A method for providing additional tractionability to a vehicle tire (20) for mitigating slippery road conditions such as ice and snow. The main embodiment for the main embodiment uses three cleats (26) per tire (20) and a cleat hub (28). Chain welts (32) and adjustable bungee cords (30) complete the install to form a contiguous unit gripping around the perimeter of the tire (20). All of the individual parts are lightweight for easy distribution to the tires (20) needing traction. They are easy to install. They are quick to install at roughly five minutes per tire (20). They are also both easy and quick to dismantle. Being solid bodied members, they are easy to keep clean by quickly hosing them down and they stack up for easy storage.
