Cleaning Pad Holder Structure Without Separate Retaining Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disposable dusting cloths require additional manufacturing steps and materials for a separate retaining sheet, increasing costs and production time, which is not efficiently addressed by existing designs.
Innovation Solution
A cleaning pad with a fusible sheet and fiber bundle layer, where the fiber bundle is fusion-bonded to the sheet, and slit openings or elastic bands are used to create retaining bands or cavities for the handle, eliminating the need for a separate retaining sheet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate holding sheet is used to retain the handle, then the cleaning pad can securely hold the handle, but the manufacturing process becomes more complex and costly
Solution Approach 1:
The patent merges the holding sheet function into the base sheet by creating integral retaining structures (pockets, channels, or folded sections) within the base sheet itself. This eliminates the need for a separate holding sheet while maintaining secure handle retention, thus reducing manufacturing complexity and costs.
Solution Approach 2:
The base sheet is designed to perform multiple functions: it provides structural support, holds the fiber bundle, and retains the handle through integrated retaining structures. This multi-functionality eliminates the need for separate components, simplifying the manufacturing process while maintaining reliability.
2Reliability
If a separate holding sheet is used to retain the handle, then the handle can be securely retained, but material usage and manufacturing costs increase
Solution Approach 1:
The holding sheet function is merged into the base sheet, eliminating the need for additional materials. The base sheet is designed with integral retaining structures that use the same material as the base sheet itself, reducing total material consumption while maintaining secure handle retention.
Solution Approach 2:
The base sheet serves multiple purposes including structural support, fiber bundle attachment, and handle retention through integrated structures. This multi-functionality reduces the quantity of materials needed by eliminating separate holding sheet components.
3Reliability
If a separate holding sheet is used, then handle retention is achieved, but production time and manufacturing steps increase
Solution Approach 1:
The retaining structures are merged into the base sheet and can be formed during the base sheet manufacturing process itself (through folding, shaping, or integrated molding). This eliminates separate assembly steps for attaching a holding sheet, thereby increasing manufacturing efficiency and productivity.
Solution Approach 2:
The base sheet is designed to provide multiple functions including handle retention through integral structures, eliminating the need for separate holding sheet components and their associated assembly steps, thus improving manufacturing efficiency.
4Reliability
If a separate holding sheet is used, then handle retention is provided, but the number of quality control checkpoints increases
Solution Approach 1:
The holding sheet function is merged into the base sheet as an integral structure, reducing the number of separate components that need to be inspected. Quality control can focus on the base sheet manufacturing process rather than separate assembly and inspection of multiple components, thereby reducing the number of quality control checkpoints.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the manufacturing process, reduces material usage, and lowers costs by integrating the retaining mechanism into the cleaning pad, resulting in a more efficient and cost-effective production method.
Implementation Method 1
a fiber bundle layer including fusible filaments. The fiber bundle layer is fusion-bonded to the fusible sheet to provide a brush portion.
Implementation Method 2
bands of material, e.g., elastic, are fused to the base sheet to create a plurality of retaining bands
Implementation Method 3
bands of material, e.g., elastic, are fused to the base sheet to create a plurality of retaining bands

AI summary
A cleaning pad or cleaning article (22) is disclosed. The cleaning article includes a combination of fibers (3) bonded to a base sheet (2). Spot bonding regions (7) and/or a central joining line (4) join fibers to the base sheet (2). The base sheet (2) further has an attachment portion for retaining the cleaning pad to a cleaning implement handle. In one embodiment, the attachment portion (13) is comprised of elongate slit openings (10) in the base sheet (2). In other embodiments, the base sheet (2) is folded over and bonded to the base sheet (2) or to itself to form a retaining cavity (33) for an attachment member (24).
