Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cleaning tools lack the ability to efficiently switch between pushing and pulling modes for optimal cleaning performance.

Innovation Solution

A squeegee designed with two wiping portions oriented differently with respect to a handle receptacle, allowing for pulling and pushing modes of operation, facilitated by a 180-degree rotation about the handle axis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a squeegee is designed with a single wiping portion oriented for pulling mode, then pulling cleaning performance is optimized, but pushing cleaning performance deteriorates

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidmode of operation flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The squeegee base is divided into two distinct wiping portions: a first wiping portion extending in a first direction for pulling mode, and a second wiping portion extending in a second direction for pushing mode. Each portion is optimized for its specific direction of use, allowing the squeegee to maintain high cleaning effectiveness in both pulling and pushing operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The squeegee is designed to perform multiple functions by incorporating two wiping portions that can be used in different modes of operation. The same squeegee device can be effectively used for both pulling and pushing cleaning tasks, eliminating the need for separate tools for different cleaning directions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a squeegee is designed with two wiping portions for both pulling and pushing modes, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvemode of operation flexibilityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Both wiping portions are integrated into a single squeegee base structure, forming one unified device. The first and second wiping portions are combined with the handle and base in a coordinated arrangement, allowing the user to switch between pulling and pushing modes without requiring separate tools or complex adjustment mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If the wiping portions are oriented at different angles, then cleaning effectiveness in different modes is improved, but manufacturing precision requirements increase

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidangular orientation accuracy

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The squeegee employs asymmetric design with the first wiping portion extending in a first direction and the second wiping portion extending in a second direction at a different angle. This asymmetric configuration optimizes the cleaning effectiveness for both pulling and pushing modes by aligning each wiping portion with the natural force application direction of its respective mode.

Inventive Principle:

Principle #4Asymmetry

AI summary

The present disclosure provides a squeegee that can be used by a user in two modes of operation—pushing or pulling the squeegee over a surface to be cleaned. To obtain an optimal squeegee that can perform the cleaning in the two modes in an optimal manner, the squeegee comprises two wiping portions, each is intended to serve a different mode of operation. Namely, one of the wiping portions is intended to be used for pulling mode and the other is intended to be used for pushing mode.
