Cleaning Article Pocket Stop Structure for Secure Holder Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning implements with holders and pockets face difficulties in secure attachment and detachment due to mismatched widths, leading to instability during use, with previous solutions causing obstruction or pocket deformation.
Innovation Solution
A cleaning implement design featuring a holder with an insertion portion that includes a bumping portion and a counter bumping portion in the pocket, allowing easy insertion and secure retention without obstruction, using a bumping mechanism to prevent further insertion and ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holder-receiving pocket is made narrower than the insertion portion of the holder to prevent detachment during cleaning, then the cleaning article remains securely attached, but the user experiences difficulty in inserting and removing the holder
Solution Approach 1:
The holder-receiving pocket is segmented into two distinct regions: a narrow bottleneck region for secure retention and a wider inlet opening region for easy insertion. This segmentation allows the pocket to provide both secure attachment during cleaning and ease of operation for holder insertion and removal.
Solution Approach 2:
The bottleneck region acts as an intermediary structure between the wide inlet opening and the retention space. It provides a transition zone that facilitates easy insertion while maintaining secure attachment, mediating between the conflicting requirements of ease of operation and attachment security.
2Ease of operation
If the holder-receiving pocket is made wider than the insertion portion of the holder to ease insertion, then the holder can be easily inserted, but the holder easily comes off during cleaning operation
Solution Approach 1:
The pocket structure is divided into functional segments: a wide inlet opening for easy insertion and a narrow bottleneck region for secure retention. This segmentation resolves the contradiction by providing different width characteristics in different regions of the same pocket.
Solution Approach 2:
Instead of making the entire pocket wide for easy insertion (which causes detachment), the design inverts the approach by making the critical retention region (bottleneck) narrow while keeping the insertion region wide. This inverted width distribution solves both problems.
3Ease of operation
If elastic deformation of the insertion portion is used to help insert the holder into the pocket, then insertion is facilitated, but the sliding between projections and bottleneck region generates considerable load causing projections to be caught, insertion plates to bend, or pockets to be broken
Solution Approach 1:
The design extracts the problematic projections from the insertion portion and replaces them with a smooth, projection-free insertion portion. This eliminates the source of the problem (projections catching in the bottleneck) while maintaining the ease of insertion benefit through the wide inlet opening design.
Solution Approach 2:
The design converts the potential harm of elastic deformation and projection catching into a benefit by using a smooth insertion portion that naturally slides through the bottleneck region without generating excessive load. The elastic deformation capacity is retained in the insertion plates themselves rather than being concentrated at projection contact points.

AI summary
A cleaning implement 1 including a cleaning article 10 having a pocket 15 and a holder 20 adapted to be inserted into the pocket 15 to hold the cleaning article 10. The pocket 15 of the cleaning article 10 has a counter bumping portion 18 in the middle between the inlet opening at one end and the opposing end thereof. The holder 20 includes a handle 21, an insertion portion 22 extending from one end of the handle 21, and a retaining means 24 for retaining the vicinity of the inlet opening of the cleaning article 10. The insertion portion 22 has a bumping portion 23 that allows the insertion portion 22 to be inserted into the pocket 15 with no substantial obstruction until it reaches a bumping position where it bumps against the counter bumping portion 18 and then restricts further insertion beyond the bumping position. The cleaning article 10 is substantially prevented from moving between the bumping portion 23 and the retaining means 24 when it has the insertion portion 22 inserted into the pocket 15 and is retained by the retaining means 24.
