Solution Overview

Problem

Existing draining devices for wet cleaning apparatuses require frequent change of washing water to prevent contamination, leading to inefficient and labor-intensive cleaning processes.

Innovation Solution

A draining device with an integrated flushing system using a fresh water reservoir connected to a rotatable draining basket, allowing for effective cleaning and rinsing with fresh water, reducing the need for used washing water and minimizing water consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wet cleaning apparatuses are washed out with used washing water, then the cleaning process can be maintained, but the washing water becomes contaminated and needs frequent changing

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidwater quality
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The device segments the water system into two separate reservoirs: a fresh water reservoir and a used water reservoir. This segmentation allows fresh water to be continuously supplied for rinsing while used water is collected separately, preventing contamination of the rinsing water and eliminating the need for frequent water changes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts the rinsing function from the draining function by adding a separate fresh water reservoir and rinsing line. This extraction allows the system to remove contaminants more effectively by providing dedicated fresh water for rinsing, separate from the water used for draining.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If washing water is changed frequently to prevent contamination, then water quality is maintained, but user convenience and time are reduced

Engineering Contradiction:
Improvewater qualityVSAvoidtime for water changes
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The device enables continuous useful action by automatically supplying fresh water through the rinsing line while the draining basket operates. The fresh water reservoir continuously provides clean water for rinsing, eliminating interruptions for manual water changes and maintaining constant water quality.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system performs self-service by automatically managing water supply and drainage functions. The fresh water reservoir and rinsing line work autonomously to provide continuous fresh water for cleaning, while the draining basket handles water removal, reducing the need for user intervention in water management.

Inventive Principle:
Principle #25Self-service

3Device complexity

If a simple draining basket is used, then device complexity is low, but cleaning effectiveness is limited

Engineering Contradiction:
Improvestructure simplicityVSAvoidcleaning effectiveness
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The invention merges two previously separate functions (draining and rinsing) into a single integrated device. The draining basket is combined with a fresh water reservoir and rinsing line, creating a dual-function device that maintains structural simplicity while significantly improving cleaning effectiveness through the addition of fresh water rinsing capability.

Inventive Principle:
Principle #5Merging (Combining)
