Solution Overview

Problem

Conventional automated washing units for heavy-duty vehicles lack efficient cleaning agent management, as cleaning agents are often discharged in a scattered manner and not collected for reuse, leading to resource inefficiency and environmental concerns.

Innovation Solution

The automated washing unit features two mobile sub-units forming a gantry-shaped tandem with washing modules that discharge and collect cleaning agents, allowing for concentrated cleaning and recirculation of used agents through extraction means, minimizing waste and optimizing resource use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If cleaning agents are discharged in a scattered manner without collection, then the washing coverage area is increased, but the loss of substance (cleaning agents) increases and resource efficiency decreases

Engineering Contradiction:
Improveloss of cleaning agentsVSAvoidwashing coverage area
Core Design Contradiction:
Loss of substanceVSArea of stationary object

Solution Approach 1:

The patent extracts and collects cleaning agents from the washing area using extraction means positioned at the discharge points. The extraction system captures cleaning agents before they are lost to the environment, separating the collection function from the discharge function to prevent scattered distribution while maintaining effective washing coverage.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements a recovery system that captures discharged cleaning agents and recirculates them back to the cleaning agent supply system. This prevents the traditional discard approach by recovering valuable cleaning agents after use, thereby reducing substance loss while maintaining adequate washing coverage through controlled discharge and recovery.

Inventive Principle:
Principle #34Discarding and recovering

2Productivity

If cleaning agents are discharged without extraction and collection, then the device complexity is reduced, but the productivity of the washing system decreases due to resource inefficiency

Engineering Contradiction:
Improvewashing efficiencyVSAvoidcomplexity of extraction system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the discharge function and extraction function into an integrated system where cleaning agents are discharged and immediately collected in close proximity. This combination of functions within a unified structure achieves efficient cleaning agent management while avoiding the complexity of separate, distributed extraction systems throughout the washing area.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces extraction means as an intermediary component between the cleaning agent discharge points and the environment. This intermediary system captures cleaning agents before they are lost, acting as a mediator that enables efficient resource management without requiring complete system redesign or excessive complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If cleaning agents are discharged in a scattered manner, then the ease of operation is maintained, but the object-generated harmful factors increase due to environmental contamination

Engineering Contradiction:
Improveenvironmental contaminationVSAvoidsimplicity of discharge system
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent converts the potentially harmful scattered discharge of cleaning agents into a beneficial recovered resource. By positioning extraction means to capture discharged cleaning agents, the system transforms what would be environmental contamination into recoverable material that can be recirculated, thereby eliminating harm while maintaining operational simplicity.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent extracts cleaning agents directly at the point of discharge before they can cause environmental contamination. This localized extraction approach prevents harmful factors by removing cleaning agents from the environment before they can spread, while keeping the discharge system simple through targeted extraction at specific discharge points rather than complex environmental containment.

Inventive Principle:
Principle #2Taking out (Extraction)
