Solution Overview

Problem

The existing cleaning tools with flat holding plates cannot efficiently utilize the sweeping-out function of fiber assemblies due to the sheet-like form of the cleaning elements, limiting their cleaning efficiency.

Innovation Solution

A cleaning tool design with a holder that inserts into a cleaning sheet, featuring an extending part with elastically deformable members to hold the sheet in a bulky three-dimensional form, enhancing the sweeping-out efficiency by making the central region thicker than the connection and tip regions, and ensuring the holder can be smoothly inserted and removed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cleaning element is held in a sheet-like form by flat holding plates, then the cleaning element can be easily held and positioned, but the sweeping-out function of the fiber assembly cannot be efficiently utilized

Engineering Contradiction:
Improveease of holdingVSAvoidcleaning efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The holding plates are designed to be movable relative to each other, allowing the cleaning element to transition from a compressed sheet-like state during insertion to an expanded three-dimensional state during cleaning operations. This dynamic structure enables the fiber assembly to achieve its full sweeping-out capability while maintaining ease of handling during attachment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention transitions the cleaning element from a two-dimensional sheet-like form to a three-dimensional bulky form by separating the holding plates. This dimensional change allows the fiber assembly to protrude and achieve effective sweeping-out contact with surfaces, resolving the contradiction between ease of holding and cleaning efficiency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the holding plates are separated to make the cleaning element bulky, then the sweeping-out function is enhanced, but the insertion and removal of the holder becomes more difficult

Engineering Contradiction:
Improvesweeping-out efficiencyVSAvoidease of insertion and removal
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The holding plates are designed with movable connections that allow them to move closer together during insertion to facilitate easy attachment, and then separate to create the bulky three-dimensional form needed for effective sweeping-out during cleaning operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The holding plates are preliminarily positioned in a closed state to facilitate easy insertion of the holder, and then separated after insertion to achieve the bulky form required for effective cleaning. This preliminary action resolves the contradiction between ease of insertion and sweeping-out efficiency.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If the cleaning element is kept flat during holding, then the holder structure is simple, but the fiber assembly cannot effectively contact surfaces

Engineering Contradiction:
Improveholder structure complexityVSAvoidsurface contact effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The holder structure incorporates movable holding plates that can transition from a closed flat configuration to an open three-dimensional configuration, enabling the fiber assembly to effectively contact surfaces while maintaining relatively simple holder construction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention introduces a three-dimensional bulky form to the cleaning element by separating the holding plates, allowing the fiber assembly to protrude and effectively contact surfaces, while the holder structure remains relatively simple through the use of movable plate connections.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Provided is a cleaning tool with which a cleaning sheet can be efficiently used during cleaning. A cleaning sheet (140) is provided with holding spaces (180) through which a cleaning-body holder (110) is inserted. The cleaning-body holder (110) is provided with: cleaning-body holding parts (130) which are inserted into the holding spaces (180) to hold the cleaning sheet (140); and a handle part (120) which is connected to the cleaning-body holding parts (130), and which is to be held by a user. The cleaning-body holding parts (130) are provided with: base parts (132) connected to the handle part (120); tip parts (133) at an opposite side to the base parts (132); and intermediate parts (134) which extend from the base parts (132) towards the tip parts (133). In a state in which the cleaning-body holding parts (130) have been inserted into the holding spaces (180) to hold the cleaning sheet (140), sections of the cleaning sheet (140) corresponding to the intermediate parts (134) are configured so as to be thicker, in the thickness direction of the cleaning sheet (140), than sections of the cleaning sheet (140) corresponding to the base parts (132).
