Solution Overview

Problem

Existing automated tyre inspection systems require handling and repositioning of tyres to inspect all surfaces, leading to deformations and reduced precision, necessitating human intervention to compensate for errors.

Innovation Solution

A support device with adjustable mechanisms and rotation means allows tyres to be inspected without handling, using vision systems to access all surfaces simultaneously, reducing human intervention and ensuring precise inspection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If the tyre is handled and repositioned during inspection to access all surfaces, then all tyre surfaces can be inspected, but the tyre undergoes deformations that reduce inspection precision

Engineering Contradiction:

Improveinspection completenessVSAvoidinspection precision

Core Design Contradiction:

Difficulty of detecting and measuringVSManufacturing precision

Solution Approach 1:

Instead of moving the tyre to inspect different surfaces, the inspection system moves around the stationary tyre. The rotary table keeps the tyre fixed in position while vision systems and inspection tools rotate around it, eliminating handling-induced deformations while still enabling complete surface inspection.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The inspection approach transitions from moving the tyre in three-dimensional space to rotating the inspection apparatus around the tyre. The rotary table enables the inspection system to access all surfaces by rotating around the stationary tyre, eliminating the need for tyre handling while maintaining inspection completeness.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Difficulty of detecting and measuring

If multiple handling operations are performed to inspect all tyre surfaces, then complete inspection is achieved, but inspection time increases and productivity decreases

Engineering Contradiction:

Improveinspection completenessVSAvoidinspection speed

Core Design Contradiction:

Difficulty of detecting and measuringVSProductivity

Solution Approach 1:

The rotary table enables continuous rotation of the inspection system around the tyre without stopping for handling operations. The tyre remains stationary while the inspection apparatus continuously moves around it, eliminating idle time associated with picking up, positioning, and repositioning the tyre between inspection stages.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

Rather than interrupting the inspection process to handle and reposition the tyre, the system inverts the approach by keeping the tyre stationary and rotating the inspection apparatus. This eliminates handling interruptions and maintains continuous inspection flow, significantly improving productivity.

Inventive Principle:

Principle #13The other way round (Inversion)

3Stability of the object's composition

If the tyre is supported on a flat surface during inspection, then the tyre is stable, but the tyre swings and deforms when rotated

Engineering Contradiction:

Improvetyre stabilityVSAvoidtyre deformation

Core Design Contradiction:

Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The support device uses a curved or cylindrical support surface that matches the tyre's circular cross-section, rather than a flat surface. This curved support cradles the tyre in its natural circular form, providing stability during rotation without causing the swinging and deformation that occurs when a circular tyre rests on a flat surface.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The support device incorporates counterbalancing mechanisms that offset the tyre's weight distribution during rotation. By providing opposing support forces through strategically positioned support points, the device prevents the tyre from swinging under its own weight while maintaining stability throughout the rotation cycle.

Inventive Principle:

Principle #8Anti-weight (Counterweight)
