Dual-Sided Cleaning Pad Pocket Structure for Easy Holder Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cleaning articles with fiber layers on both sides of a holder-receiving pocket face challenges in inserting and removing the holder due to fiber interference, leading to inefficient use and potential halfway-attached states, especially when made of soft materials.
Innovation Solution
The design features oblong substrate sheets forming tubular pockets with unjoined regions at the inlet ends, allowing for easy insertion of a holder by pinching the end portions to create open inlets, and using heat-embossed bonds for increased stiffness and flexibility, ensuring the holder can be securely attached and detached without fiber layer interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fiber layers are provided on both sides of the pocket, then both sides of the cleaning article can be used for cleaning purposes, but the fibers can cover the inlet opening of the pocket to interfere with inserting the holder into the pocket
Solution Approach 1:
The pocket is divided into two distinct regions: a first region with an open inlet opening for holder insertion, and a second region where fiber layers are provided for cleaning functions. This segmentation allows the holder to be inserted through the open first region without fiber interference, while still enabling both-sided cleaning capability through the fiber layers in the second region.
2Adaptability or versatility
If the pocket is made of soft materials such as fibers, then the cleaning article is flexible, but it is not easy to insert the stick-shaped insertion portion to the intended deepest position of the pocket
Solution Approach 1:
The pocket exhibits different physical properties in different regions: the first region has a looser, more open structure that facilitates easy insertion of the holder to the intended deepest position, while the second region maintains the necessary flexibility and softness for cleaning functions. This local differentiation of structural properties resolves the contradiction between flexibility and ease of insertion.
3Adaptability or versatility
If only the fiber layer on one side is soiled, then the cleaning article must be once detached from and re-attached to the holder to change the fiber layers, but this process is time-consuming and inefficient
Solution Approach 1:
The pocket is pre-configured with fiber layers on both sides during manufacturing, with one side having superior soil-holding performance and the other having superior stain-removal performance. This preliminary arrangement allows users to quickly switch between cleaning functions by simply flipping the cleaning article, eliminating the need for time-consuming detachment and re-attachment operations.

AI summary
A cleaning article 10 having a pair of flat tubular pockets 15 and attachable to a holder 20 by inserting the holder 20 into the pockets 15. The cleaning article 10 includes fiber layers 11a and 11b and fiber layers lie and 11d each formed of a fiber bundle on the upper and lower side, respectively, of the pockets 15. The pockets 15 are formed by joining two oblong sheets 13a and 13b interposed between the upper and lower fiber layers 11b and lie by making joining zones extending in the longitudinal direction of the sheets 13a and 13b to define both longer sides of each pocket I5. The pockets 15 each have an unjoined region in an end portion on the side of their inlets 151.
