Cleaning Sheet Bent Region for Easy Holder Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cleaning tools with grip insertion parts formed by grip attaching sheets are not user-friendly due to the closure of the insertion opening when the sheets are in close contact, making it difficult for users to attach the grip.
Innovation Solution
A method of manufacturing a cleaning tool with a cleaning sheet and holder, where the cleaning sheet has a base and a fiber assembly that is stretched and bonded to form a bent region, creating an open insertion opening for the holder, ensuring easy attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If grip attaching sheets are in close contact with each other, then the structure is compact and stable, but the insertion opening is closed making it difficult for users to attach the grip
Solution Approach 1:
The bent region is pre-formed in the grip attaching sheet during manufacturing, creating a built-in mechanism that automatically maintains the insertion opening in an open state. This preliminary structural action eliminates the need for manual manipulation to open the insertion opening during attachment, resolving the contradiction between structural compactness and ease of operation.
2Ease of operation
If a bent region is formed in the base to maintain an open insertion opening, then user-friendliness is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The bent region is formed by changing the geometric parameters of the grip attaching sheet during manufacturing. By introducing a pre-formed bent region with specific curvature and dimensions, the insertion opening remains open during use while the manufacturing process incorporates this feature through standard forming techniques, balancing ease of operation with manufacturing feasibility.
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
The method facilitates user-friendly attachment of the holder to the cleaning element by maintaining an open insertion opening, enhancing the usability of the cleaning tool.
Implementation Method 1
stretching at least part of fibers of the first fiber assembly by applying a prescribed tension at least to the first fiber assembly
Implementation Method 2
bonding the stretched first fiber assembly to the base
Implementation Method 3
forming a bent region in the base by releasing the application of tension from the first fiber assembly and thereby shrinking the fibers stretched by the tension

AI summary
Provided is a production method for a cleaning tool (A) provided with a cleaning sheet (100), and a holding tool (200) for holding the cleaning sheet (100). The cleaning sheet (100) is provided with: a base part (120); and a first fibre assembly (110GF1) which is bonded to the base part (120). The production process includes a step in which tensile force imparted to the first fibre assembly (110GF1) is released, and fibres (110SF) in a state of having been stretched by the tensile force are shrunk to form bent regions (120E) in the base part (120).
