Solution Overview

Problem

Existing devices for cleaning the inner surface of pneumatic tires are inefficient due to a suction device that is firmly connected to the laser, limiting its independence and ability to operate at higher beam intensities, which can damage the suction device and result in incomplete cleaning.

Innovation Solution

The suction device is positioned at a distance of at least 5 cm to 50 cm from the laser positioning device, allowing independent operation and enabling the laser to be used at higher intensities, with additional suction devices and protective measures to enhance component removal and prevent damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the suction device is firmly connected to the laser positioning device, then the structure is simplified, but the suction device cannot operate independently and may be damaged by high laser intensity

Engineering Contradiction:
ImprovestructureVSAvoidsuction device damage risk
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The cleaning system is divided into two independent functional modules: a laser positioning device for loosening components and a separate suction device for removing detached components. This segmentation allows each device to operate independently without being damaged by the other, while maintaining simplified individual structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The suction device is extracted from the laser positioning device structure and positioned separately at a distance of 5-50 cm. This extraction eliminates the risk of laser beam damage to the suction device while preserving the ability to effectively remove detached components from the tire inner surface.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If the suction device is positioned close to the laser beam, then detached components can be removed immediately, but the suction device may be damaged by the laser beam

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidlaser beam damage to suction device
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

A spatial distance of 5-50 cm is introduced as an intermediary zone between the laser beam and suction device. This distance is sufficient to prevent laser damage to the suction device while maintaining close enough proximity to effectively capture and remove detached components, thus mediating between productivity and safety requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Power

If the laser is operated at high beam intensity, then cleaning effectiveness is improved, but the suction device nearby may be damaged

Engineering Contradiction:
Improvelaser beam intensityVSAvoidsuction device damage risk
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The suction device is extracted from the immediate vicinity of the laser beam and positioned at a safe distance of 5-50 cm. This extraction enables the laser to operate at high beam intensities for effective cleaning without risking damage to the suction device, thus resolving the contradiction between power and reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

4Device complexity

If the suction device is fixed at the laser position, then the structure is compact, but the device lacks flexibility in cleaning different locations

Engineering Contradiction:
ImprovestructureVSAvoidcleaning location flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The cleaning system is segmented into independent laser positioning and suction devices that can be positioned separately. This segmentation provides flexibility to target different locations on the tire inner surface while maintaining compact individual device structures, resolving the contradiction between structural simplicity and operational versatility.

Inventive Principle:
Principle #1Segmentation
