Solution Overview

Problem

The existing wheel cleaning technologies fail to effectively remove burrs from the edges of weight-reducing pits on wheel flanges, leading to potential corrosion issues during vehicle use.

Innovation Solution

A comprehensive cleaning device comprising a lower lifting driving system, side brush system, ring brush system, clamping driving system, and pressing system, which work together to rotate brushes and adjust their positions to remove burrs from both the center and edge areas of weight-reducing pits on wheel flanges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If weight-reducing pits are arranged on the wheel flange to reduce wheel weight, then fuel economy is improved, but burrs are generated on the edges of the pits which cause corrosion failure

Engineering Contradiction:
Improvewheel weightVSAvoidcorrosion failure
Core Design Contradiction:
Weight of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by implementing a cleaning device that removes burrs from the edges of weight-reducing pits immediately after the casting process. The device includes cleaning components positioned to contact the wheel flange surface and remove burrs before the wheel enters service, preventing corrosion failure while maintaining the weight-reducing pit design

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent converts the harmful burrs generated during casting into a controllable parameter by using them as indicators of the cleaning device's effectiveness. The cleaning components are designed to specifically target and remove these burrs, transforming the previously harmful feature into a controlled aspect of the manufacturing process that ensures wheel reliability

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If manual cleaning methods are used to remove burrs, then corrosion failure is prevented, but productivity is low and labor costs are high

Engineering Contradiction:
Improvecorrosion failureVSAvoidcleaning efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent implements self-service by designing an automatic cleaning device that performs the burr removal function without requiring manual intervention. The device is integrated into the wheel manufacturing process and automatically cleans the wheel flange surface, eliminating the need for separate manual cleaning operations while maintaining high cleaning effectiveness

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical cleaning with an automated mechanical cleaning system. The cleaning device uses controlled mechanical components (such as brushes or abrasive elements) driven by motors or other power sources to remove burrs automatically, substituting human labor with a mechanized system that improves productivity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If existing wheel cleaning technologies are used, then some cleaning is achieved, but burrs on the edges of weight-reducing pits are not effectively removed

Engineering Contradiction:
Improvecleaning capabilityVSAvoidburr removal effectiveness
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies local quality by designing cleaning components that are specifically positioned and configured to target the edges of weight-reducing pits where burrs are generated. The cleaning device includes specialized components (such as localized brushes or abrasive elements) that concentrate cleaning action on the critical areas where burrs form, rather than applying uniform cleaning throughout the entire wheel flange surface

Inventive Principle:
Principle #3Local quality
