Tire Slip Prevention Wire Tensioning Device with Automatic Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire slip prevention wire tensioning devices fail to securely attach to tires, leading to disengagement and accidents due to incorrect operation, tampering, or external collisions, causing the wire to be drawn out by centrifugal force during vehicle operation.
Innovation Solution
A wire tensioning device with a control mechanism featuring locking teeth and a biasing system that automatically switches to a secure winding state when the wire is drawn out, ensuring constant tension and preventing disengagement, utilizing a wheel with a winding bias and a manual operation part for switching between locking states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual operation member is used to switch between fixing locations, then the device can be operated to prevent tire slip, but the device becomes vulnerable to wrong operation, forgotten operation, tampering, or collision that may cause the wire to be drawn out by centrifugal force
Solution Approach 1:
The device automatically switches between the first and second fixing locations based on the winding state of the wire, without requiring manual operation. The automatic switching mechanism detects the wire tension state and autonomously adjusts the locking tooth engagement, eliminating the need for user intervention and preventing errors from wrong or forgotten operations
Solution Approach 2:
The device incorporates a feedback mechanism where the automatic switching mechanism monitors the wire tension and winding state, and automatically adjusts the position of the locking tooth on the toothed rim. This closed-loop control ensures the device maintains the correct fixing location based on real-time wire state, preventing disengagement even during tampering or collision events
2Strength
If the fixing claw meshes with the toothed rim at the first fixing location to prevent wire motion in the tension direction, then the wire is secured during winding, but the device cannot prevent wire motion in the opposite direction without additional mechanisms
Solution Approach 1:
The device dynamically switches between two fixing locations depending on the operational phase. During wire winding, the locking tooth engages the first fixing location to prevent wire motion in the tension direction. During wire release or tensioning, it automatically switches to the second fixing location to prevent motion in the opposite direction, providing adaptive bidirectional control without requiring complex simultaneous restraint mechanisms

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 effectively maintains wire tension and prevents disengagement from the tire, even in cases of malfunction or external interference, ensuring the tire slip prevention device remains securely attached during vehicle operation.
Implementation Method 1
a control mechanism (6) which controls rotating motion of the wheel (3), comprising: a first locking tooth (62) which engages with the tooth parts (37) and prevents the wheel from rotating in a direction to release the wire (4), a second locking tooth (63) which engages with the tooth parts (37) and prevents the wheel from rotating in the direction to wind the wire (4), and biasing means (7) which applies bias to the locking tooth (62, 63), which is at least one of the first locking tooth (62) or the second locking tooth (63), towards the tooth parts (37) formed on the wheel (3)
Implementation Method 2
a wheel (3) which is supported about an axis in the case (2) and which can wind up the wire (4), a winding biasing means (5) which applies bias to the wheel (3) in a direction to wind the wire (4)

AI summary
[Problem] The present invention is designed to provide a wire tensioning device which, even when the wire tensioning device for preventing tire slip is operated erroneously or malfunctions, can prevent the wire from being drawn out from the wire tensioning device while the car is running. [Solution]The present invention includes a plurality of tooth parts formed on a wheel, a first locking tooth that engages with the tooth parts and prevents the wheel from rotating in the direction to release the wire, and a second locking tooth that engages with the tooth parts and prevents the wheel from rotating in the direction to wind the wire, and a biasing means that applies bias to the locking tooth, which is at least one of the first locking tooth or the second locking tooth, towards the tooth parts formed on the wheel, and a first motion for switching from the state in which the second locking tooth is engaged with the tooth parts formed on the wheel to the state in which the first locking tooth is engaged is carried out by the motion to draw out the wire wound around the wheel.
