Adjustable Tire Valve Mounting for Rim Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire pressure monitoring systems face issues with securely fastening the valve to the housing and limiting the adjustability of the angle between the valve and the housing, which can lead to damage and failure when used with different types of rims due to improper installation angles.
Innovation Solution
A tire pressure monitoring system where the tire valve is securely fastened to the enclosure using a hinge joint with a rotatable member and a form-fitting connection, allowing for adjustable angles of up to -90 to +90 degrees, ensuring proper installation on various rim profiles without risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed angle connection between sensor housing and valve is used, then the mounting structure is simple, but the sensor can only be mounted on specific rim types and may be damaged on other rims
Solution Approach 1:
The hinge joint enables dynamic adjustment of the angle between the sensor housing and valve, transforming a static fixed-angle connection into a dynamic adjustable connection. This allows the mounting structure to adapt to different rim types while maintaining structural simplicity through a single degree of freedom mechanism.
Solution Approach 2:
The mounting structure is segmented into two independent components: the valve assembly and the sensor housing, connected through a hinge joint. This segmentation allows each component to be optimized independently while providing adaptability through the articulated connection, resolving the conflict between simplicity and versatility.
2Ease of operation
If the valve is merely slid onto the valve connector without form-fitting fastening, then the assembly is simple, but additional measures are needed to secure the assembly and prevent separation
Solution Approach 1:
The form-fitting connection design allows the valve to self-secure to the rotatable member through geometric interlocking features. The connection structure itself provides the securing function without requiring additional fastening components, achieving both ease of assembly and reliable connection through self-service mechanism.
3Reliability
If a hinge joint with form-fitting connection is used, then the valve is securely fastened and angle adjustability is improved, but the mounting structure becomes more complex
Solution Approach 1:
The hinge joint and form-fitting connection are merged into a single integrated mounting structure. The rotatable member serves dual functions: providing the hinge joint for angle adjustment and incorporating form-fitting connection features for secure fastening. This merging reduces the number of separate components and simplifies the overall structure while achieving both reliability and adjustability.

AI summary
An assembly comprising a tyre valve (2) and an enclosure (3), wherein the enclosure (3) is adapted to receive a gas pressure monitoring unit, wherein the enclosure (3) comprises a hinge joint, the hinge joint having at least one stationary member connected to the enclosure (3), an axle (6) and a rotatable member (4) arranged to at least partially rotate around the axle (6) and wherein the tyre valve (2) is connected to the rotatable member (5) of the hinge joint. The tyre valve (2) is connected to the rotatable member (4) of the hinge joint by a form-fitting connection which secures the tyre valve (2) against movement in a direction towards the rotatable member (4) and in a direction away from the rotatable member (5).
