Solution Overview

Problem

Cleaning devices, such as brooms, mops, and squeegees, often face a compromise between having a wide cleaning head for efficiency and a narrow head for navigating tight spaces, lacking the ability to seamlessly adjust between these configurations.

Innovation Solution

A variable-width cleaning device with a horizontal head portion that can be controllably expanded or retracted via a vertical handle movement, allowing the head to assume any width between narrow and wide configurations, utilizing a handle assembly and adaptor system to facilitate horizontal movement and interchangeable cleaning surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the cleaning head is made wide, then cleaning efficiency is improved, but the ability to navigate narrow spaces deteriorates

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidability to navigate narrow spaces
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The cleaning head incorporates a telescopic mechanism with sliding components that allow the width to be dynamically adjusted. The head can be extended to a wide configuration for efficient cleaning of large areas and retracted to a narrow configuration for navigating under furniture and in tight spaces, making the cleaning device adaptable to different cleaning scenarios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cleaning head is divided into separable sections that can slide relative to each other. This segmentation allows the head to be configured in different widths by extending or retracting the telescopic components, enabling the device to switch between wide and narrow configurations as needed.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the cleaning head is made narrow, then adaptability to narrow spaces is improved, but cleaning efficiency deteriorates

Engineering Contradiction:
Improveability to navigate narrow spacesVSAvoidcleaning efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The telescopic mechanism enables the cleaning head to dynamically change its width. When navigating narrow spaces, the head is retracted to a compact narrow configuration. When cleaning large open areas, the head is extended to a wide configuration, maximizing cleaning efficiency. This dynamic adjustment resolves the trade-off between narrow adaptability and wide-area productivity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cleaning device achieves multi-functionality by incorporating a telescopic head that can assume both narrow and wide configurations. This allows a single device to perform both tasks: navigating tight spaces under furniture with a narrow profile and efficiently cleaning large floors when extended to a wide configuration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If the cleaning head width is fixed, then device complexity is reduced, but versatility deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidcontrollability of cleaning head width
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The telescopic mechanism adds controlled complexity to enable width adjustment. The sliding components and connecting structures allow the head width to be changed on demand, providing versatility while maintaining reasonable structural simplicity through the use of straightforward mechanical elements.

Inventive Principle:
Principle #15Dynamics
