Reusable Outer Shell with Segmented Pockets for Wash-Safe Insert Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reusable outer shells for absorbent inserts face challenges in providing improved leakage security, comfort, and ease of use, particularly due to difficulties in attaching and maintaining the absorbent insert correctly, and issues with elastic integration and hook material functionality during washing.
Innovation Solution
A reusable outer shell with separate front and rear pockets, each with varying lengths and elastic members, and strategically positioned hook members, designed to stabilize and securely hold the absorbent insert, while minimizing hook material interference during washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer shell is provided with hook materials for releasable fastening of the absorbent insert, then the attachment functionality is improved, but the hook materials may attach to other parts of the outer shell or to other items during washing, causing cleaning issues and damage
Solution Approach 1:
The outer shell is divided into a front pocket and a rear pocket, with hook materials strategically positioned in specific regions. This segmentation allows the hook materials to be localized in areas where they can effectively attach the absorbent insert while minimizing the risk of unwanted attachment to other parts of the shell during washing.
Solution Approach 2:
Hook materials are provided in specific local regions of the outer shell rather than uniformly distributed. The front pocket and rear pocket are designed with hook materials positioned to optimize attachment functionality while reducing the overall surface area with adhesive properties, thereby minimizing unwanted attachment during washing.
2Reliability
If elastics are provided in direct connection with the absorbent insert to prevent leakage, then leakage security is improved, but the construction becomes more complex and material consumption increases
Solution Approach 1:
The outer shell is segmented into distinct front and rear pockets with different lengths, allowing elastic elements to be strategically positioned at specific locations. This segmentation enables effective leakage prevention through targeted elastic placement rather than requiring elastics in direct connection with the entire absorbent insert, thereby reducing construction complexity.
3Duration of action of stationary object
If the outer shell is designed to be washable and reusable, then economic and environmental benefits are achieved, but the hook material functionality may be impaired and cleaning becomes difficult
Solution Approach 1:
The outer shell is divided into front and rear pockets with hook materials positioned in specific regions. This segmentation isolates the hook materials to areas where they are less likely to cause cleaning difficulties while maintaining their attachment functionality, thereby preserving reusability without compromising cleaning ease.
Solution Approach 2:
Hook materials are localized to specific regions rather than being uniformly distributed, reducing the overall surface area that requires special cleaning attention. This local quality approach maintains attachment functionality while minimizing the impact on cleaning ease and reusability.
