Solution Overview

Problem

Existing cleaning and disinfecting machines have complex and prone-to-failure designs with external supply pipes that complicate operation and reduce usable space, leading to inefficiencies and increased resource usage.

Innovation Solution

The supply pipe for the spraying device is arranged inside the washing chamber, eliminating external pipes and allowing for a larger washing area with reduced leakage risks and flow losses, while maintaining the machine's external dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If supply pipes are arranged outside the washing chamber, then the washing area is reduced, but the leakage risk and flow losses are increased

Engineering Contradiction:
Improvewashing areaVSAvoidleakage risk
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The supply pipe is integrated inside the washing chamber, merging the fluid supply function with the washing space. This eliminates external piping that would reduce washing area and minimizes leakage risks by containing all supply components within the sealed chamber environment.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If supply pipes are arranged outside the washing chamber, then installation is simplified, but flow losses increase and washing area decreases

Engineering Contradiction:
Improveinstallation simplicityVSAvoidflow losses
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The supply pipe is extracted from the external environment and placed inside the washing chamber. This shortens the fluid path, eliminating flow losses associated with external piping while the integrated design simplifies installation by reducing the number of external connections and sealing points.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If external supply pipes are used, then the machine structure is simplified, but the usable washing space is reduced

Engineering Contradiction:
Improvestructure simplicityVSAvoidusable washing space
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The supply pipe is positioned in the vertical dimension inside the washing chamber, utilizing the depth of the chamber rather than occupying horizontal washing space. This dimensional arrangement allows the supply system to coexist with the washing area without reducing usable space, while the integrated structure actually simplifies the overall machine design.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
