Solution Overview

Problem

Traditional cleaning equipment requires manual maintenance and has low cleaning efficiency due to the need for continuous operation and labor-intensive cleaning processes.

Innovation Solution

A cleaning device with a driving roller, driven roller, flexible cleaning belt, garbage collection box, sewage collection tank, clean water tank, and water squeezing roller, which automates the cleaning process by using clean water to maintain the belt's cleanliness and reduce labor intensity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

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 after a while, increasing labor intensity and reducing cleaning efficiency

Engineering Contradiction:
Improvelabor intensityVSAvoidcleaning efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The cleaning device automatically cleans the cleaning belt through a water supply system that sprays clean water onto the belt, and a squeezing system that removes dirty water, eliminating the need for manual cleaning operations and enabling continuous autonomous work

Inventive Principle:
Principle #25Self-service

2Productivity

If traditional cleaning equipment operates continuously, then cleaning coverage increases, but the cleaning parts become dirty and require manual cleaning, reducing overall cleaning efficiency

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidcleaning time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The cleaning belt is continuously cleaned during operation through the water supply system and squeezing system, allowing the device to maintain cleaning effectiveness throughout extended operation without interruption for manual maintenance

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Clean water is supplied to the cleaning belt before it becomes excessively dirty, preventing accumulation of污垢 and maintaining optimal cleaning performance throughout the operation cycle

Inventive Principle:
Principle #10Preliminary action

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

The device allows for efficient single-session cleaning, reducing labor intensity and improving cleaning efficiency by automatically managing moisture and waste on the cleaning belt.

Implementation Method 1

Sewage water and excess water on the cleaning belt are squeezed into the sewage collection tank by the water squeezing roller

Methodology Applied
Scientific EffectMechanical squeezing: Mechanical Force

Implementation Method 2

clean water in the clean water tank flows onto the cleaning belt to clean the cleaning belt

Methodology Applied
Scientific EffectFluid cleaning: Fluid Spray
