Cleaning Sheet with Bent-Region Base for Open Grip 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, involving stretching fibers, bonding them to a base, and forming a bent region by releasing tension to create an open insertion opening, ensuring the grip can be easily attached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grip attaching sheets are in close contact with each other, then the structure is compact and secure, but the insertion opening is closed making it difficult for users to attach the grip
Solution Approach 1:
The grip attaching sheets are designed with elastic deformation capability, allowing them to dynamically change from a closed state during storage to an open state during attachment. The sheets can be elastically deformed to open the insertion opening when the grip is being attached, and then automatically return to the closed secure state after attachment, providing both ease of operation and reliable attachment.
2Ease of operation
If the insertion opening is kept open for easy grip attachment, then user-friendliness is improved, but the grip attaching sheets cannot provide secure holding
Solution Approach 1:
The grip attaching sheets utilize elastic deformation to create a dynamic structure that can open for attachment and close for secure holding. When the grip is being attached, the sheets are elastically deformed to open the insertion opening. After attachment, the elastic force causes the sheets to return to their original closed state, providing secure holding while maintaining ease of attachment.
3Stability of the object's composition
If grip attaching sheets are designed to close tightly, then structural integrity is maintained, but the insertion opening becomes inaccessible for users
Solution Approach 1:
The grip attaching sheets are designed with elastic properties that allow them to temporarily open the insertion opening when needed for attachment, while maintaining structural integrity in the closed state. The elastic deformation enables the sheets to open during the attachment process and then automatically close to maintain structural integrity, providing both accessibility and stability.
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
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 forming 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
To provide a production method for a cleaning tool and a cleaning body with which the attachment of a holding tool to the cleaning body is facilitated. Provided is a production method for a cleaning tool provided with a cleaning sheet, and a holding tool for holding the cleaning sheet. The cleaning sheet is provided with: a base part; and a first fiber assembly which is bonded to the base part. The production process includes a step in which tensile force imparted to the first fiber assembly is released, and fibers in a state of having been stretched by the tensile force are shrunk to form bent regions in the base part.
