Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vacuum cleaners face challenges in efficiently collecting thin and long contaminants like hair and waste threads from surfaces, especially fibrous ones, due to the need for separate blower units which increase manufacturing costs and noise, and can leave behind contaminants on sticky surfaces.

Innovation Solution

A suction nozzle with a contaminant attachment unit featuring a tape roller and elastic support system, allowing for effective collection of contaminants without additional noise or increased manufacturing costs, by using a tape roller that can be easily extended and contracted, and an elastic support unit to maintain contact with the surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a blower unit is added to the suction nozzle to improve contaminant collection efficiency, then the ability to remove contaminants from carpets is improved, but manufacturing costs increase and noise is generated

Engineering Contradiction:

Improvecontaminant collection efficiencyVSAvoidmanufacturing cost

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the contaminant removal function from a separate blower unit and integrates it into the suction nozzle itself through the contaminant attachment unit. This eliminates the need for additional driving units while maintaining the ability to remove contaminants from carpets and other surfaces.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The suction nozzle is designed to perform multiple functions: it maintains its primary suction function while also incorporating the contaminant attachment unit that can actively remove contaminants from surfaces. This multi-functionality eliminates the need for separate blower units.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If a blower unit is added to the suction nozzle to improve contaminant collection efficiency, then the ability to remove contaminants from carpets is improved, but noise increases

Engineering Contradiction:

Improvecontaminant collection efficiencyVSAvoidnoise

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent eliminates the noise-generating blower unit by extracting its function and replacing it with a passive contaminant attachment unit that operates without additional driving mechanisms, thereby removing the noise source while maintaining contaminant removal capability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of manufacture

If suction force alone is used to draw in contaminants, then manufacturing costs are kept low, but thin and long contaminants like hair are not effectively collected from sticky surfaces

Engineering Contradiction:

Improvemanufacturing costVSAvoidcontaminant collection efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent merges the suction function with the contaminant attachment function in a single integrated unit. The contaminant attachment unit is positioned to work in conjunction with the suction port, combining passive attachment with active suction to effectively collect thin and long contaminants from sticky surfaces without requiring separate blower units.

Inventive Principle:

Principle #5Merging (Combining)

4Productivity

If the contaminant attachment unit is made to contact the surface directly, then contaminant collection efficiency is improved, but the unit may damage the surface

Engineering Contradiction:

Improvecontaminant collection efficiencyVSAvoidsurface damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The elastic support unit acts as an intermediary between the contaminant attachment unit and the surface. It provides compliant support that allows the attachment unit to contact the surface gently, adapting to surface irregularities without causing damage while still enabling effective contaminant collection.

Inventive Principle:

Principle #24Intermediary (Mediator)
