3D Cleaning Sheet Holder for Better Dirt Sweeping
Find Innovative SolutionsGenerate Solutions
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 where the cleaning sheet is held in a three-dimensional form by a holder with an extending part that thickens the central region, allowing for enhanced sweeping-out efficiency, and an engagement part with a larger cross-sectional area than the opening to maintain the sheet in a bulky state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cleaning element is held in sheet-like form by flat holding plates, then the cleaning element can be easily held by the holder, but the sweeping-out function of the fiber assembly cannot be efficiently used
Solution Approach 1:
The patent transitions the cleaning element from a two-dimensional sheet-like form to a three-dimensional bulky form by introducing an extending part that protrudes from the holder. This dimensional change allows the fiber assembly to protrude outward, enabling effective sweeping-out function while maintaining ease of holding through the holder structure.
Solution Approach 2:
The extending part is designed to be flexible and deformable, allowing it to adapt dynamically during cleaning operations. The fiber assembly can bend and flex to conform to surfaces while maintaining the bulky form necessary for sweeping-out function, combining structural support with operational flexibility.
2Productivity
If the cleaning sheet is made thicker in the central region, then the sweeping-out efficiency is enhanced, but the device structure becomes more complex
Solution Approach 1:
The patent combines the holder structure with the extending part into an integrated component. The extending part is formed as an integral extension of the holder body, eliminating the need for separate attachment mechanisms and reducing overall device complexity while achieving the required thickness enhancement for sweeping-out efficiency.
Solution Approach 2:
The extending part utilizes flexible material properties to achieve the bulky form without requiring complex rigid structural support. The flexibility allows the extending part to maintain its shape while adapting to cleaning surfaces, simplifying the overall structure compared to rigid thickening methods.

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