Solution Overview

Problem

Traditional cleaning equipment requires manual cleaning of the cleaning belt, leading to labor-intensive operations and reduced efficiency due to the need for frequent maintenance and prolonged cleaning sessions.

Innovation Solution

A cleaning device with a driving roller, driven roller, flexible cleaning belt, garbage collection box, brush, sewage collection tank, clean water tank, and water squeezing rollers, where clean water flows onto the belt to clean it, and sewage and excess water are squeezed into the sewage collection tank, eliminating the need for manual cleaning and maintaining the belt's moisture content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional cleaning equipment is used with a motor driving cleaning parts to rotate, then the cleaning function is achieved, but manual cleaning of the cleaning parts is required frequently, increasing labor intensity and reducing cleaning efficiency

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidlabor intensity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The cleaning device performs self-cleaning through an automated system where a water supply component delivers clean water to the cleaning belt, and a water squeezing component removes dirty water and debris from the belt, eliminating the need for manual cleaning operations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The harmful function of dirty water and debris accumulating on the cleaning belt is extracted and removed through the water squeezing component, which separates and discharges the contaminants from the cleaning belt into a collection container

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If manual cleaning of the cleaning belt is performed, then the cleaning belt can be maintained, but the cleaning session must be interrupted and time is lost

Engineering Contradiction:
Improvecleaning belt cleanlinessVSAvoidcleaning session interruption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The cleaning device maintains continuous operation by automatically cleaning the cleaning belt during the cleaning process, with the water supply component and water squeezing component operating continuously to prevent interruptions in the cleaning session

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Clean water is supplied to the cleaning belt in advance to prevent dirt accumulation, and the water squeezing component continuously removes contaminants before they can affect cleaning performance, maintaining belt cleanliness proactively rather than reactively

Inventive Principle:
Principle #10Preliminary action

3Duration of action of moving object

If the cleaning belt accumulates dirty water and debris, then the cleaning device can operate continuously, but the cleaning belt becomes less effective and requires manual cleaning

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidcleaning belt performance
Core Design Contradiction:
Duration of action of moving objectVSReliability

Solution Approach 1:

The water squeezing component acts as an intermediary between the cleaning belt and the dirty water collection container, continuously removing contaminants from the belt and transferring them to the collection container, thereby maintaining belt performance during continuous operation

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system continuously discards dirty water and debris from the cleaning belt through the water squeezing component and collection container, while clean water is continuously supplied to replace the removed water, maintaining the cleaning belt's effectiveness throughout operation

Inventive Principle:
Principle #34Discarding and recovering

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case
