Solution Overview

Problem

Existing vacuum cleaner nozzles are inefficient for cleaning corners and narrow passages due to their shape and dimensions, requiring users to change nozzles or move furniture to access waste, and struggle with smooth surfaces due to reduced suction efficiency and noise.

Innovation Solution

A vacuum cleaner nozzle with a substantially angular triangular sole and articulated connection to the suction tube, featuring multiple suction channels and deflectors to maintain parallel movement and efficient suction, along with rollers and bristles for effective waste collection on various surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the nozzle has a standard shape and dimensions, then it is easy to manufacture and use on open surfaces, but it cannot effectively reach corners or narrow passages

Engineering Contradiction:

Improveability to clean corners and narrow passagesVSAvoiddifficulty to position nozzle over waste

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connection between the suction tube and sole is made articulated rather than rigid, allowing the nozzle to dynamically adapt its angle and position while maintaining parallel contact with the surface during movement, enabling effective cleaning in corners and narrow passages

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The suction system is divided into multiple independent suction channels (front channel, rear channel, lateral channels) distributed across the sole, allowing different zones to independently access waste in various geometries including corners and narrow passages

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the nozzle is positioned at an angle to reach corners, then it can access narrow passages, but the suction efficiency decreases and the nozzle may not remain parallel to the surface

Engineering Contradiction:

Improveaccess to corners and narrow passagesVSAvoidsuction efficiency and parallel movement

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The articulated connection allows the suction tube to pivot independently while the sole maintains parallel contact with the surface, dynamically preserving suction efficiency regardless of the nozzle's orientation relative to the surface being cleaned

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Multiple suction channels are strategically positioned (front, rear, lateral) to ensure that at least one channel maintains effective suction contact with the surface even when the nozzle is angled for corner cleaning

Inventive Principle:

Principle #1Segmentation

3Reliability

If the suction channels are open directly towards the surface, then suction efficiency on smooth floors is improved, but noise increases

Engineering Contradiction:

Improvesuction efficiency on smooth floorsVSAvoidnoise

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

Different suction channels have different configurations optimized for their specific functions: front and rear channels open directly to the surface for high efficiency on smooth floors, while lateral channels provide angled access for corners, allowing each zone to operate optimally for its intended purpose

Inventive Principle:

Principle #3Local quality
