A method and apparatus for processing vehicle tires involve determining the amount of thixotropic balancing substance needed based on tire characteristics, applying it uniformly to circumferential areas, and using nanostructures to enhance distribution, along with delimiters to define balancing areas and improve noise reduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual methods are used for tire balancing and processing, then flexibility and adaptability are maintained, but processing efficiency and productivity are low

Engineering Contradiction:

Solution Approach 1:

The tire processing system uses self-service mechanisms where the tire itself is rotated and positioned automatically by the processing apparatus, and the balancing substance is applied automatically based on detected tire characteristics, reducing the need for manual intervention while maintaining processing quality

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The processing apparatus integrates multiple functions including tire rotation, balancing substance application, and noise reduction treatment in a single automated system, enabling one device to perform multiple operations that previously required separate manual processes

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If balancing substance is applied to address mass distribution issues, then tire balance improves, but processing time and complexity increase

Engineering Contradiction:

Solution Approach 1:

The system determines the required amount of balancing substance and identifies the optimal application location before actually applying the substance, allowing for precise targeting that reduces the amount of material needed and minimizes processing time while achieving accurate balance

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of uniformly applying balancing substance throughout the tire, the system applies the substance locally at specific circumferential areas where mass distribution deficiencies are detected, achieving effective balancing with minimal material and reduced processing time

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If nanostructures are applied to enhance balancing substance distribution, then balancing effectiveness improves, but device complexity and manufacturing cost increase

Engineering Contradiction:
