Tire Condition Detection Device Valve Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire condition detecting devices are primarily designed for clamp-in valves and cannot accommodate snap-in valves, limiting their versatility to attach different types of tire valves.
Innovation Solution
A tire condition detecting device with multiple attachment portions, including specific configurations for snap-in and clamp-in valves, allowing for the attachment of various tire valve types by aligning the attachment positions with the device's center of gravity and rotation radius to prevent twisting and ensure secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tire condition detecting device is designed with a structure based on clamp-in valve attachment, then the fastening nut is prevented from loosening by centrifugal force, but snap-in valves cannot be attached and various types of clamp-in valves cannot be accommodated
Solution Approach 1:
The case is designed with multiple types of attachment portions (first attachment portion for snap-in valves, second attachment portion for clamp-in valves) that can accommodate different valve types. This universal design allows the same tire condition detecting device to be used with various tire valve types, resolving the contradiction between reliability and versatility.
2Stability of the object's composition
If the attachment portion for snap-in valve is arranged at the center of gravity, then the valve body portion is prevented from twisting during rotation, but the attachment position for clamp-in valve must be different to ensure proper rotation radius
Solution Approach 1:
Different attachment portions are provided at different locations on the case, with each location optimized for its specific valve type. The first attachment portion is positioned at the center of gravity for snap-in valves to prevent twisting, while the second attachment portion is positioned to provide appropriate rotation radius for clamp-in valves. This localized optimization resolves the contradiction between stability and device complexity.
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
Enables the attachment of multiple types of tire valves, reducing manufacturing costs and minimizing valve deterioration by matching attachment positions with the device's center of gravity and optimizing the attachment structure for each valve type, ensuring secure and durable mounting.
Implementation Method 1
The attachment portion for a snap-in valve is arranged to be matched with a center of gravity of the tire condition detecting device
Implementation Method 2
The attachment portion for a clamp-in valve is arranged at a position at which a rotation radius of the case is not a minimum when the case is rotated around a rotation axis that is a central axis of a clamp-in valve attached to the attachment portion for a clamp-in valve
