Solution Overview

Problem

Existing electronic units for measuring vehicle wheel parameters face challenges in securely attaching to the rim during tire mounting and removal, requiring manual adjustment and resulting in potential breakage due to stress loadings, and are costly due to complex angularly adaptable connections.

Innovation Solution

An electronic unit with a spring-effect elastic attachment system comprising an insert with a pivoting mechanism and a sleeve, allowing automatic contact with the rim and adaptable to various valve types, ensuring secure attachment without manual intervention and accommodating different rim shapes and dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a rigid connection between the valve and electronic casing is used, then the electronic casing can be securely retained against the rim, but the connection breaks under stress loadings during tire mounting and removal

Engineering Contradiction:

Improveretention strengthVSAvoidconnection reliability

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent applies a dynamic connection principle by enabling the electronic casing to pivot relative to the valve body through a ball joint mechanism. This dynamic articulation allows the casing to adjust its angular orientation automatically, maintaining contact with the rim bottom while accommodating stress variations during tire mounting and removal operations, thereby preventing connection breakage

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the angular orientation parameter of the electronic casing relative to the valve body. By allowing the casing to rotate about a ball joint, the system adapts the angular parameter dynamically to maintain optimal contact with the rim bottom under varying load conditions, resolving the contradiction between secure retention and connection reliability

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the electronic casing is pressed firmly against the rim bottom, then contact is maintained during tire operations, but manual adjustment is required and complex angularly adaptable connections increase cost

Engineering Contradiction:

Improvecontact reliabilityVSAvoidconnection complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by designing the electronic casing with an automatic pivot mechanism that self-adjusts its angular orientation to maintain contact with the rim bottom. The ball joint connection enables the casing to automatically find and maintain the correct position without requiring manual adjustment or complex angularly adaptable connection systems, thereby reducing device complexity while maintaining contact reliability

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If ancillary components are used for angular adjustment, then adaptability to different rim profiles is achieved, but manufacturing cost increases

Engineering Contradiction:

Improverim profile adaptabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent achieves universality by designing a simple ball joint connection that provides multi-functional capability: it enables angular adjustment for different rim profiles, maintains secure retention, and allows automatic adaptation during tire operations. This single universal mechanism replaces the need for multiple ancillary components, thereby maintaining rim profile adaptability while reducing manufacturing cost

Inventive Principle:

Principle #6Universality (Multi-functionality)
