Integrated Tire Changing and Balancing Machine

Solution Overview

Problem

Existing tire-changing machines for motor vehicles require separate equipment for tire removal and wheel balancing, leading to high costs, space requirements, and operational complexity.

Innovation Solution

A tire-changing machine that integrates a bearing frame with a tire-changing device and a wheel balancing device, allowing for both tire removal and balancing operations within a compact design, utilizing a spindle support element, bead breaker arm, and a wheel balancing device with identification and measurement means to calculate offset masses and their application points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate tire-changing machine and balancing machine are used, then each machine can perform its specific function, but the overall cost increases and space requirements increase

Engineering Contradiction:

Improvefunctional capabilityVSAvoidspace requirement

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines a tire-changing machine and a wheel balancing machine into a single integrated device. The tire-changing device includes a support element for the wheel and a tool for removing the tire, while the balancing device includes a shaft for rotating the wheel and identification/measurement means for determining imbalance. Both devices share a common base element and frame structure, allowing both functions to be performed in one location without requiring separate machines.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated machine serves multiple functions: it can both remove tires from wheels and perform wheel balancing operations. The support element and tool assembly enable tire changing, while the shaft and measurement means enable balancing. This multi-functional design eliminates the need for operators to manage separate specialized machines.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate tire-changing machine and balancing machine are used, then each machine can perform its specific function, but the investment cost increases
