Solution Overview

Problem

Existing devices for cleaning profiled surfaces, such as roof tiles and sheets, lack a simple and efficient mechanism for adjusting the cleaning pins to match the surface dimensions without risking their inclination.

Innovation Solution

A support plate with parallel grooves at specific distances, allowing pins to be mounted perpendicularly and adjusted using bolt connections, combined with foam-covered ends to maintain the polymer material and prevent inclination, and a fastening mechanism for secure adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pins are mounted on traditional supports for cleaning profiled surfaces, then cleaning function is provided, but pins are at risk of being inclined from their intended positions

Engineering Contradiction:

Improvepin position stabilityVSAvoidadjustability to surface dimensions

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The support plate incorporates multiple grooves that allow pins to be dynamically repositioned along the grooves to match different profiled surface dimensions, while the plate structure itself provides static stability to prevent pin inclination

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The support is segmented into a plate structure with multiple grooves, allowing individual pins to be independently positioned and adjusted within the groove system, enabling both stability and adaptability

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If pins are made adjustable to match different surface dimensions, then adaptability is improved, but the risk of pin inclination increases

Engineering Contradiction:

Improveadjustment to surface dimensionsVSAvoidpin position stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The grooves act as intermediary guides that constrain pin movement to a predetermined path, allowing adjustment to different positions while preventing inclination from the intended positions perpendicular to the grooves

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If traditional cleaning devices are used on profiled surfaces, then basic cleaning is achieved, but cleaning efficiency is insufficient

Engineering Contradiction:

Improvecleaning efficiencyVSAvoidsupport structure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The support plate with its groove system serves multiple functions: it provides structural stability, enables pin adjustment to various positions, guides pin orientation, and accommodates different profiled surface dimensions, all within a single simple structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A device for cleaning of profiled surfaces, especially roof coverings, is disclosed. It comprises a support, carrying a number of side to side vertically arranged pins (8-15). The support is designed like a vertical plate (1) with horizontal elongation. This plate (1) is carried (2) by a shaft, and is provided with at least two parallel horizontal grooves (4,5,6,7), arranged at a first distance (3) from each other. In these said pins (8-15) are mountable directed at right angle to the grooves (4,5,6,7) by bolt connections (16,17).
