Solution Overview

Problem

Existing surface cleaners with fluid delivery and recovery systems lack efficient tools for handling both fine and coarse debris, particularly in terms of debris capture and self-cleaning mechanisms.

Innovation Solution

The development of a cleaning tool with a suction nozzle featuring an adjustable lens and an agitator block that can switch between agitation and self-clean positions, allowing for enhanced debris capture and tool maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed suction channel volume is used in the suction nozzle, then the device structure is simple, but it cannot effectively capture both fine and coarse debris

Engineering Contradiction:
Improvedebris capture capabilityVSAvoidlens adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lens is made adjustable between retracted and extended positions, allowing the suction channel volume to dynamically change. This enables the same nozzle to handle both fine debris (with smaller suction channel volume) and coarse debris (with larger suction channel volume), resolving the contradiction between adaptability and device complexity

Inventive Principle:
Principle #15Dynamics

2Reliability

If the suction nozzle is used without a self-cleaning mechanism, then the device structure is simpler, but debris accumulates in the suction channel reducing cleaning effectiveness

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidself-cleaning mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The suction nozzle is equipped with a self-cleaning mechanism that allows it to clean itself by reversing the suction flow or using the suction force to remove accumulated debris from the suction channel. This self-service capability maintains cleaning effectiveness without requiring external intervention, resolving the contradiction between reliability and device complexity

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the lens is always in the extended position to maximize suction channel volume, then coarse debris capture is improved, but fine debris capture and suction efficiency are reduced

Engineering Contradiction:
Improvecoarse debris captureVSAvoidsuction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The lens position is made dynamically adjustable, allowing the user to retract it for fine debris capture (maintaining high suction efficiency) or extend it for coarse debris capture (increasing suction channel volume). This dynamic adaptation resolves the contradiction between adaptability and productivity by optimizing performance for different debris types

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles
