Solution Overview

Problem

Existing cleaning devices for smooth surfaces like solar collectors and photovoltaic elements face issues such as damage from excessive load, inability to monitor the cleaning process visually, and limitations in cleaning larger areas, due to inadequate load transfer and reliance on special vehicles.

Innovation Solution

A device with a cleaning unit and linkage featuring an intercepting or adjusting device that diverts the load, allowing for adjustable and minimal load transfer, combined with an operating unit for visual monitoring, and the option to use universal lifting platforms or self-drive, eliminating the need for special vehicles and reducing operator strain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the entire load of the cleaning device is transferred to the surface via wheels, then the device can be supported and positioned, but the surface of solar collectors or photovoltaic elements may be damaged by excessive load

Engineering Contradiction:
Improvedevice support stabilityVSAvoidsurface damage from load
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

A support arm acts as an intermediary between the cleaning device and the surface, allowing the device to be supported without transferring excessive load directly to the fragile surface. The support arm can be adjusted to provide adequate support while limiting the force applied to the cleaned surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The linkage is designed with adjustable support arms that can dynamically adapt their position and load-bearing capacity. This allows the device to maintain stability while adjusting the load distribution to prevent surface damage during the cleaning process.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the device is operated from the ground, then operator safety is improved, but visual monitoring of the cleaning work becomes impossible

Engineering Contradiction:
Improveoperator safetyVSAvoidvisual monitoring capability
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

Visual monitoring is replaced by technical aids such as cameras or sensors mounted on the cleaning device. These devices transmit images or data to the operator, allowing monitoring of the cleaning process without requiring the operator to be in visual contact with the work area.

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

3Manufacturing precision

If a fixed cleaning device is used, then the cleaning unit can effectively clean surfaces, but it cannot clean larger areas such as large photovoltaic elements

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidcleaning area coverage
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The linkage is designed as an extendable and adjustable mechanism that can adapt its length and position. This allows the cleaning unit to reach different areas and accommodate various surface sizes, from small solar collectors to large photovoltaic installations, while maintaining effective cleaning contact.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cleaning device is divided into modular components, including an extendable linkage and adjustable support arms. This segmentation allows the device to be configured for different cleaning scenarios and surface areas, enhancing versatility while maintaining cleaning effectiveness.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If special vehicles are used to operate the cleaning device, then the device can reach and clean surfaces, but operational costs increase and operator strain increases

Engineering Contradiction:
Improveaccess to cleaning surfacesVSAvoidvehicle requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning device is extracted from the requirement of special vehicles and designed to be operable from the ground using a simple, lightweight structure. The support arm and adjustable linkage provide sufficient reach and stability without needing complex vehicle-based systems, reducing both cost and operational complexity.

Inventive Principle:
Principle #2Taking out (Extraction)
