Solution Overview

Problem

Traditional surface cleaning methods, such as pressure washing and hand washing, are inefficient, labor-intensive, and environmentally harmful, particularly when cleaning irregular surfaces at high altitudes or hard-to-reach locations, as they waste water and fuel, cause damage to surfaces, and pose safety risks.

Innovation Solution

A scrub plate system with a switchable magnetic wheel, a vacuum rail system, and a control system for an irregular surface cleaning system that allows for bottom-up cleaning, reducing water waste, and enabling remote operation, while being environmentally friendly and safer for users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If pressure washing is used to clean surfaces, then cleaning effectiveness is improved, but water waste and environmental harm increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidwater waste
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The system captures and recycles water during the cleaning process. The vacuum cleaner collects water used for cleaning along with contaminants, separating and storing it for reuse. This resolves the contradiction by recovering what would otherwise be wasted water while maintaining effective cleaning performance.

Inventive Principle:
Principle #34Discarding and recovering

2Loss of substance

If hand washing is used to clean surfaces, then water waste is reduced, but labor intensity and safety risks increase

Engineering Contradiction:
Improvewater consumptionVSAvoidlabor intensity
Core Design Contradiction:
Loss of substanceVSEase of operation

Solution Approach 1:

The system performs cleaning operations autonomously without requiring human operators to physically contact or approach the surfaces being cleaned. The automated vehicle navigates and cleans surfaces independently, eliminating the need for manual labor while maintaining water efficiency through its designed cleaning mechanism.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If traditional cleaning methods are used on irregular surfaces, then accessibility is improved, but surface damage increases

Engineering Contradiction:
Improveaccessibility to irregular surfacesVSAvoidsurface damage
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system changes the parameters of the cleaning action by using controlled water application followed by vacuum collection, rather than high-pressure washing. This parameter change allows effective cleaning of irregular surfaces while preventing damage through gentler, more controllable cleaning forces.

Inventive Principle:
Principle #35Parameter changes

4Speed

If pressure washing is used, then cleaning speed is improved, but fuel consumption and environmental harm increase

Engineering Contradiction:
Improvecleaning speedVSAvoidfuel consumption
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

The system replaces the fuel-based pressure washing mechanism with an electrically-powered vacuum-based system. This substitution eliminates fuel consumption while maintaining cleaning speed through the coordinated action of water application and immediate vacuum collection, resolving the contradiction between speed and energy loss.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
