Cleaning Element Holding Structure for Low-Resistance Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning tools with sheet-type cleaning elements face challenges in simplifying the structure for holding the cleaning element, which affects ease of attachment and usability.
Innovation Solution
The cleaning element features fusion-bonded parts that form a holding space with a concave portion for secure attachment, reducing sliding resistance and stabilizing the cleaning element, allowing for a simplified holding mechanism and enhanced cleaning performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional holding structure is used for the cleaning element, then the cleaning element can be attached to the holder, but the structure becomes complex and difficult to manufacture
Solution Approach 1:
The holding structure is merged with the cleaning element itself by forming holding protrusions directly on the cleaning element that engage with corresponding recesses in the holder. This integration eliminates the need for separate, complex holding mechanisms while maintaining secure attachment functionality.
Solution Approach 2:
The cleaning element is designed with multi-functionality by incorporating holding protrusions that serve both as structural support and as attachment mechanisms. This allows the cleaning element to perform both cleaning and holding functions, simplifying the overall device structure.
2Ease of manufacture
If the cleaning element structure is simplified for easier attachment, then the manufacturing process becomes easier, but the voluminous feeling and dust retention capability may be reduced
Solution Approach 1:
The cleaning element features local quality variations with denser fiber arrangements in specific regions that enhance dust retention while maintaining an overall simplified structure. This localized optimization ensures reliable dust capture without requiring complex overall design.
Solution Approach 2:
The cleaning element utilizes composite material structures combining different fiber types and densities to achieve both simplified manufacturing and effective dust retention. The composite structure allows for easy attachment while maintaining high voluminous feeling and cleaning performance.
3Reliability
If fusion bonded parts are used to attach the cleaning element to the holder, then the attachment becomes secure, but the sliding resistance increases making insertion difficult
Solution Approach 1:
The attachment interface is segmented into discrete holding protrusions and corresponding recesses rather than a continuous fusion bonded surface. This segmentation allows for controlled engagement points that provide secure attachment while reducing overall friction during insertion.
Solution Approach 2:
The holding protrusions act as intermediary elements between the cleaning element and holder, providing localized fusion bonding points that ensure secure attachment without requiring extensive surface contact, thereby reducing sliding resistance during insertion.

AI summary
It is an object of the present invention to provide an effective technique for a higher cleaning effect and higher operability of a cleaning element (110) of a cleaning tool (100). The cleaning element (110) comprises a base sheet (111a), a holding sheet (112), first and second groups of fusion bonded parts (114,115,116) which are discontinuously formed along a predetermined direction to fusion bond the base sheet (111a) and the holding sheet (112) overlaid to each other, and a holding space (118) demarcated by the first and second groups between the base sheet (111a) and the holding sheet (112). The holding space (118) has at least one open end (118a, 118b) in the predetermined direction. The cleaning eletnent (110) is provided with a fusion bonded part (114) having a curved portion (114a) concaved to the holding space (118) for engagement with an attachment (133).
