Solution Overview

Problem

Conventional cleaning implements require frequent replacement or extensive cleaning, leading to inefficiencies and increased costs when used for household dusting, as they lose effectiveness over time.

Innovation Solution

A cleaning implement with a support structure and multiple detachable cleaning sheets that can be easily refreshed by removing soiled sheets, allowing continued use without replacing the entire tool, with features like slits forming loops for increased surface area and a handle attachment for convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If conventional cleaning implements are used for household dusting, then they can perform basic cleaning functions, but they require frequent replacement or extensive cleaning, leading to inefficiencies and increased costs

Engineering Contradiction:
Improveservice life of cleaning implementVSAvoidcleaning efficiency
Core Design Contradiction:
Duration of action of moving objectVSProductivity

Solution Approach 1:

The cleaning implement is divided into a reusable support structure and replaceable cleaning sheets. The sheets can be individually removed and replaced when soiled, while the support remains in use. This segmentation allows the cleaning function to be refreshed without replacing the entire implement, resolving the contradiction between service life and cleaning efficiency.

Inventive Principle:
Principle #1Segmentation

2Duration of action of moving object

If multiple cleaning sheets are stacked and detachably supported on the support, then the cleaning implement can be refreshed multiple times without replacement, but the device complexity increases

Engineering Contradiction:
Improvenumber of refreshesVSAvoidstructure complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The cleaning sheets are segmented as separate, detachable components that can be independently removed from the support. This segmentation enables multiple refreshes without increasing overall system complexity, as each sheet operates as an independent replaceable unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleaning function is extracted into separate detachable sheets that can be removed and replaced independently from the support structure. This extraction allows the support to remain in continuous use while only the consumable sheets are replaced, extending the overall service life without permanent complexity increases.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the cleaning sheets are configured to allow easy detachment, then users can expose additional cleaning sheets without replacing the entire implement, but the attachment mechanism becomes more complex

Engineering Contradiction:
Improveease of sheet replacementVSAvoidattachment mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning sheets are designed as disposable or easily replaceable components with simple attachment mechanisms. The low cost and simple design of individual sheets allow for easy detachment and replacement without requiring complex attachment mechanisms, resolving the contradiction between ease of operation and device complexity.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

A cleaning implement (10) is disclosed with a support sheet (20) having a first surface, a second surface, and a longitudinal axis. A plurality of detachable cleaning sheets (30), each having an outwardly facing cleaning surface (31) and an inwardly facing attachment surface (33), may be supported by the support sheet (20) in a stacked configuration. A plurality of folded portions (40) included with the support sheet (20) and the cleaning sheet (30) extend generally radially from the longitudinal axis of the cleaning implement (10). The outermost cleaning sheet (35) may be removed from the stacked cleaning sheet (30) to expose a new, fresh cleaning sheet (30).
