Tire Anti-slip Device Wire Guide Curvature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire anti-slip devices face challenges in securely mounting to tires due to frictional resistance and difficulty in manipulating connectors, especially in snowy conditions, leading to inefficient installation and potential dirt contamination.
Innovation Solution
A tire anti-slip device with a wire guide member featuring curved portions and wire access holes directed towards the anti-slip body, allowing the tightening wire to be easily guided and fixed, reducing frictional resistance and enabling secure mounting without the need for complex inner-side hooking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are provided in both inner and outer side positions of the tire to connect both ends of the anti-slip body, then the anti-slip device can be securely mounted to the tire, but it becomes difficult to perform the connection work in the inner side position where arm insertion gap is small and dirt is easily adhered
Solution Approach 1:
The invention extracts the connector from the inner side position of the tire, eliminating the need to perform connection work in the difficult-to-access inner side area. The connector is provided only at the outer side position, allowing all connection operations to be performed from the outer side where there is sufficient space and visibility.
Solution Approach 2:
Instead of providing connectors at both inner and outer sides as in conventional designs, the invention inverts the approach by providing the connector only at the outer side position. This allows the tightening wire to pass through the anti-slip body from the outer side, connecting both ends without requiring inner side access.
2Ease of operation
If a strap-like tensioning member is used to fasten the inner side of the tire by drawing both ends from the outer side, then the mounting work can be performed in the outer side position, but the anti-slip body is attracted toward the inner side requiring additional steps to move it back to the outer side
Solution Approach 1:
The invention incorporates curved portions in the wire guide member that guide the tightening wire along a curved path from the outer side through the anti-slip body. This curved guidance ensures that when both ends of the tightening wire are drawn from the outer side, the anti-slip body is attracted toward the outer side rather than the inner side, eliminating the need for additional steps to reposition it.
Solution Approach 2:
The wire guide member acts as an intermediary component that mediates the force transmission from the tightening wire to the anti-slip body. The curved portions of the wire guide member redirect the pulling force so that it acts in the outward direction, ensuring the anti-slip body moves toward the outer side during tightening.
3Ease of operation
If wire access holes are directed toward the anti-slip body with curved portions in the wire guide member, then the tightening wire can be easily guided with reduced frictional resistance, but the structure becomes more complex
Solution Approach 1:
The wire guide member is designed with curved portions that smoothly guide the tightening wire from the wire access hole through the anti-slip body. These curved portions reduce frictional resistance by providing a smooth transition path for the wire, preventing sharp bends that would increase friction and make wire insertion difficult.
Solution Approach 2:
The wire guide member has different structural characteristics at different locations: the curved portions are specifically designed where the wire passes through to reduce friction, while other parts maintain a simpler structure. This localized optimization provides ease of wire guidance only where needed without unnecessarily complicating the entire structure.

AI summary
[Problems] In order to obtain a tire anti-slip device which includes an anti-slip body having a tread portion making contact with the ground, inner link portions formed to protrude from the tread portion to the inner side of the tire, and outer link portions formed to protrude from the tread portion to the outer side of the tire, and a tightener configured to tightly fit the anti-slip body to the tire, and can prevent removal of the anti-slip body from the inner or outer side direction of the tire in operation of the tightener so that the tire anti-slip device can be mounted to an optimum position of the tire with a simple manipulation, [Solution] a wire guide portion capable of guiding the tightening wire in the width direction of the anti-slip body is formed in a position of one end portion of the anti-slip body, and one end position (of the wire guide member) and the other end position of the anti-slip body approach each other in both positions of the inner and outer link portions by tightening the tightening wire.
