Tire Valve Axial Connection Offset for Faster Air Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire valves are inefficient for quickly changing air pressure, particularly deflation, and often require cumbersome couplings that can be prone to jamming, especially at higher pressures, and are not optimized for smaller tires.
Innovation Solution
A tire valve design with a one-piece valve body featuring a connection section offset axially from the valve-functional elements, allowing for a larger diameter valve channel and secure coupling without threading, enabling faster air flow and reduced weight for smaller tires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the connection means is arranged in the radial direction with respect to the valve-functional elements, then the valve structure is compact, but the valve channel diameter is limited and air flow speed is reduced
Solution Approach 1:
The connection means is moved from a radial arrangement to an axial arrangement along the valve channel, transitioning the connection direction to a different spatial dimension. This allows the valve-functional elements to be positioned outside the tube of the valve base without radial interference, enabling a larger valve channel diameter and faster air flow while maintaining compact overall dimensions through axial stacking
2Ease of manufacture
If the valve body is made in one piece, then manufacturing complexity is reduced and weight is decreased, but structural strength may be compromised
Solution Approach 1:
The valve body is segmented into functionally distinct sections: a connection section for mounting and a valve-functional section for air control. This segmentation allows each section to be optimized independently while maintaining a one-piece construction, achieving both manufacturing simplicity and adequate structural strength through functional zoning
3Reliability
If a coupling is screwed onto the external thread of the tube, then secure connection is achieved, but the operation becomes awkward and time-consuming
Solution Approach 1:
The threading function is extracted from the tube and relocated to the valve body's connection section. This allows the valve to be screwed directly onto the tube without requiring additional couplings, eliminating the cumbersome coupling operation while maintaining secure threaded connection through the valve body's own threading
4Productivity
If the valve-functional elements are positioned within the tube of the valve base, then the valve structure is compact, but the valve channel diameter is constrained and air flow is limited
Solution Approach 1:
The valve-functional elements are repositioned from a radial arrangement within the tube to an axial arrangement outside the tube. This dimensional change allows the valve channel to expand in diameter without increasing the radial footprint, achieving faster air flow while maintaining compact overall structure through axial extension
