Solution Overview

Problem

Existing gutter cleaners have limited usability and a restricted field of application, making them inefficient for various cleaning tasks due to fixed cleaning tools and inability to adapt to different gutter shapes and sizes.

Innovation Solution

A gutter cleaner apparatus with movable cleaning tools, including a brush and scraper, that can be slidably mounted and configured to adapt to different positions and shapes, allowing for improved handling and extended application by providing adjustable cleaning tools and liquid guidance for enhanced cleaning efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed cleaning tools are used in gutter cleaners, then the structure is simple, but the field of application is limited and usability is restricted

Engineering Contradiction:
Improvefield of applicationVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The first cleaning tool is made movable relative to the second cleaning tool through a sliding mechanism. The first cleaning tool can be positioned in different locations along the cleaning portion, allowing it to be moved between an idle position and a forward position. This dynamic positioning enables the gutter cleaner to adapt to different cleaning tasks and gutter configurations, resolving the contradiction between versatility and structural simplicity.

Inventive Principle:
Principle #15Dynamics

2Productivity

If multiple cleaning tools are provided at the cleaning portion, then the cleaning efficacy is improved, but the device complexity increases

Engineering Contradiction:
Improvecleaning efficacyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple cleaning tools (first cleaning tool and second cleaning tool) into a single integrated cleaning portion. The first cleaning tool is movably mounted on the cleaning portion, allowing it to share space with the second cleaning tool. This merging approach enables multiple cleaning functions to be performed by a unified structure, improving cleaning efficacy while controlling device complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the first cleaning tool is movably mounted with respect to the second cleaning tool, then the adaptability to different cleaning tasks is improved, but the ease of operation becomes more complex

Engineering Contradiction:
Improveadaptability to cleaning tasksVSAvoidhandling
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The first cleaning tool is designed with a sliding mechanism that allows it to move along the cleaning portion between an idle position and a forward position. This dynamic design enables easy repositioning of the first cleaning tool to adapt to different cleaning tasks. The sliding mechanism provides intuitive and simple operation, maintaining ease of handling while achieving high adaptability.

Inventive Principle:
Principle #15Dynamics
