Solution Overview

Problem

Conventional conveyance mechanisms, such as conveyor belts, suffer from residual material accumulation during manufacturing processes, which can contaminate both the mechanism and subsequent articles, leading to operational issues and contamination.

Innovation Solution

A self-cleaning ring conveyor system featuring parallel rings with scrapers that effectively reduce residual material accumulation by using a combination of materials like silicone-based rings and scrapers with specific designs to minimize adhesion and efficiently remove contaminants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conveyor belt is used to transport components through manufacturing processes, then support and frictional contact are provided for effective transport, but residual material from surface treatments accumulates on the conveyor belt causing contamination

Engineering Contradiction:
Improvetransport effectivenessVSAvoidresidual material accumulation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The conveyor belt is segmented into multiple parallel rings that can be independently cleaned. Each ring passes through scraping slots, allowing residual material to be removed from individual segments rather than requiring cleaning of the entire continuous belt at once.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The scraping slots are positioned to remove residual material before it can accumulate significantly or transfer to subsequent components. The cleaning action occurs continuously during operation, preventing contamination rather than addressing it after the fact.

Inventive Principle:
Principle #10Preliminary action

2Force

If the conveyor belt surface area is increased to provide sufficient contact with components, then transport support and friction are improved, but the surface area for residual material accumulation also increases

Engineering Contradiction:
Improvefrictional contactVSAvoidcontamination surface area
Core Design Contradiction:
ForceVSObject-generated harmful factors

Solution Approach 1:

By dividing the conveyor into multiple parallel rings, the total surface area is maintained for adequate frictional contact, but each individual ring's surface area is reduced, limiting the amount of residual material that can accumulate on any single ring segment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the conveyor system have different functions: the upper surfaces of the rings provide frictional contact for component transport, while the sides of the rings interact with the scraping slots for cleaning. This local differentiation optimizes both transport effectiveness and cleanability.

Inventive Principle:
Principle #3Local quality

3Object-generated harmful factors

If a cleaning mechanism is added to remove residual material, then contamination is reduced, but device complexity increases

Engineering Contradiction:
Improveresidual material transferVSAvoidcleaning system structure
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The conveyor system performs its own cleaning function through the scraping slots that remove residual material from the rings during normal operation. This self-cleaning capability is integrated into the conveyor structure itself, eliminating the need for separate external cleaning mechanisms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning function is merged with the transport function by integrating the scraping slots directly into the conveyor ring structure. The same rings that transport components also serve as the surfaces to be cleaned, combining two functions into a single integrated system.

Inventive Principle:
Principle #5Merging (Combining)
