Solution Overview
Problem
Existing cleaning tools with sheet-type cleaning elements lack effectiveness and operability in efficiently cleaning diverse surfaces, including flat, curved, uneven, and stepped surfaces inside and outside buildings and vehicles.
Innovation Solution
A cleaning element comprising a fiber assembly with a nonwoven fabric and fusion bonded parts, where the fiber assembly includes a first fusion bonded part extending across the direction of the fiber assembly and second fusion bonded parts formed discontinuously to enhance bonding strength and volume, allowing the element to conform to surfaces and trap dust effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a sheet-type cleaning element is used for wiping surfaces, then the cleaning tool can cover large areas, but the cleaning effect on diverse surfaces (flat, curved, uneven, stepped) is insufficient
Solution Approach 1:
The cleaning element incorporates a fiber assembly with regions of different fiber lengths (first and second fiber extending parts with different lengths) to create local variations in cleaning capability. Longer fibers reach into crevices on uneven surfaces while shorter fibers provide effective contact on flat surfaces, allowing the single cleaning element to adapt to diverse surface geometries and maintain reliable cleaning effect across the entire cleaning area.
2Volume of stationary object
If the fiber assembly is made voluminous to trap dust effectively, then the dust trapping capability improves, but the bonding strength between layers may be compromised
Solution Approach 1:
The fiber assembly is segmented into multiple regions with different functions: a first fiber extending part for dust trapping, a second fiber extending part for surface contact, and intermediate fusion bonded parts that分段 bond these regions together. This segmentation allows each region to optimize its volume for its specific function while the distributed fusion bonded parts maintain overall structural integrity and bonding strength throughout the assembly.
Solution Approach 2:
The cleaning element uses a composite structure combining fibers of different materials or treatments (implied by the distinction between first and second fiber extending parts) bonded together through fusion bonded parts. This composite approach allows the fiber assembly to achieve both high volume for dust trapping and sufficient bonding strength through the integrated multi-material structure.
3Strength
If fusion bonded parts are extended continuously to bond the fiber assembly and nonwoven fabric, then bonding strength improves, but the cleaning element becomes less adaptable to curved and uneven surfaces
Solution Approach 1:
The continuous bonding structure is segmented into discrete fusion bonded parts distributed across the cleaning element. These segmented bonding regions provide sufficient total bonding strength while leaving gaps between them that allow the fiber assembly to flex and conform to curved and uneven surfaces, thereby maintaining both strength and adaptability.
4Ease of manufacture
If the cleaning element structure is simplified for easy manufacture, then manufacturing cost decreases, but the cleaning effect and operability are reduced
Solution Approach 1:
The invention optimizes key parameters of the fiber assembly (fiber length distribution, fusion bonded part spacing and size, nonwoven fabric properties) to achieve effective cleaning performance. By carefully selecting and controlling these parameters within practical ranges, the design maintains a relatively simple overall structure that is easy to manufacture while still delivering superior cleaning effect through the optimized parameter combinations.

AI summary
A cleaning element includes a fiber assembly having a plurality of fibers extending in a predetermined direction and a nonwoven fabric disposed on the fiber assembly. A first fusion bonded part extends in a cross direction crossing the predetermined direction to fusion bond the fiber assembly and the nonwoven fabric, and a plurality of second fusion bonded parts formed discontinuously in the cross direction at a lateral side of the first fusion bonded part to fusion bond the fiber assembly and the nonwoven fabric. The first fusion bonded part extends all the way through the fiber assembly in a thickness direction of the cleaning element. The plurality of second fusion bonded parts extend only a part of said fiber assembly in the thickness direction.
