Cleaning Sheet Tension Structure for Bulky Surface Sweeping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cleaning tools with sheet-type cleaning elements held by bifurcated holders fail to efficiently utilize the sweeping-out function of fiber assemblies due to the sheet-like form, limiting the effectiveness of the cleaning process.
Innovation Solution
A cleaning tool design featuring a cleaning sheet with distinct high-rigidity and low-rigidity regions, where the holder applies tension to the sheet to form a tension part, allowing the sheet to be held in a bulky state and enhancing the sweeping-out function by increasing contact with surfaces, thereby improving cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cleaning element is held in sheet-like form by the holder, then the cleaning element can be easily held and positioned, but the sweeping-out function of the fiber assembly cannot be efficiently utilized
Solution Approach 1:
The cleaning element is designed to dynamically change its shape from a planar sheet-like form during insertion to a bulky three-dimensional form during cleaning operation. The holder applies tension to transform the cleaning element's configuration, enabling the fiber assembly to protrude and utilize its sweeping-out function effectively while maintaining ease of handling during insertion.
Solution Approach 2:
The physical state of the cleaning element is changed from a flat, two-dimensional sheet to a volumetric, three-dimensional bulky form through tension application. This parameter change in shape and volume allows the fiber assembly to extend outward and engage with surfaces for effective sweeping-out action, resolving the contradiction between ease of holding and cleaning efficiency.
2Device complexity
If the cleaning element is kept in planar form, then the holder structure can be simple, but the fiber assembly cannot effectively contact and sweep surfaces
Solution Approach 1:
Rather than designing a complex holder to force a bulky shape, the invention uses a simple tension-applying holder that allows the cleaning element to dynamically transform from planar to bulky form during operation. This dynamic approach maintains holder simplicity while enabling effective surface contact through the cleaning element's own structural response to tension.
3Productivity
If the cleaning element is transformed to bulky state, then the fiber assembly can effectively sweep surfaces, but the holder insertion becomes more difficult
Solution Approach 1:
The cleaning element is designed to be in a pre-compressed or folded state that allows easy insertion into the holder. Once inserted, the holder's tension application triggers the transformation to the bulky operational form. This preliminary configuration resolves the contradiction by enabling easy insertion first, followed by automatic transformation to the effective cleaning configuration.
Solution Approach 2:
The cleaning element undergoes a dynamic transformation sequence: starting in a compact planar form for easy insertion, then transitioning to a bulky three-dimensional form after insertion when tension is applied. This dynamic behavior allows the system to optimize for insertion ease and then for cleaning effectiveness at different operational stages.

AI summary
To provide a cleaning tool with which a cleaning sheet can be efficiently used during cleaning. [Solution] The present invention relates to a cleaning tool (100) comprising a holding tool (110) for holding a cleaning sheet (140). In a state in which holding parts (130) of the holding tool (110) are inserted into insertion parts (180) of the cleaning sheet (140), tension imparting parts (190) of the holding parts (130) impart tensile force on second regions (180B) of the cleaning sheet (140) to form tension portions (191), and sheet members (151) in the tension portions (191) in a length-intersecting direction (X) are moved in directions in which first regions (180A) are disposed.
