Reusable Outer Shell Pocket Layout for Secure Absorbent Insert Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reusable outer shells for absorbent inserts face challenges in providing improved leakage security, comfort, and ease of use, with issues related to elastic integration and hook material functionality during washing.
Innovation Solution
A reusable outer shell with separate front and rear pockets, each with distinct dimensions and elastic members, and hook members arranged within the pockets to securely hold the absorbent insert, along with leg and waist elastics for enhanced leakage prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hook materials are used for releasable fastening of the absorbent insert, then the absorbent insert can be easily attached and detached, but the hook material functionality is impaired during washing and undesired attachment occurs
Solution Approach 1:
The hook material is extracted from the main body of the outer shell and placed inside the pockets. This separation allows the hook material to be isolated from direct washing exposure while still enabling easy attachment and detachment of the absorbent insert through the pocket openings.
Solution Approach 2:
The hook material is nested within the pocket structure, specifically positioned inside the front and rear pockets. This nesting protects the hook material during washing while maintaining its fastening function when the pocket is open for insert attachment.
2Reliability
If elastic elements are provided in direct connection with the absorbent insert, then leakage prevention is improved, but the construction complexity and material consumption increase
Solution Approach 1:
The pocket structure serves as an intermediary between the elastic elements and the absorbent insert. The elastic elements are integrated into the pocket rather than directly connecting to the insert, simplifying the overall construction while maintaining leakage prevention through the pocket's containment function.
3Adaptability or versatility
If the outer shell is made washable and reusable, then environmental impact is reduced, but cleaning difficulty increases due to hook material attachment issues
Solution Approach 1:
The hook material is extracted from the main shell body and relocated to the pockets, separating the washing-prone shell material from the attachment-functional hook material. This allows the shell to be washed more easily while the hook material remains protected and functional.
Solution Approach 2:
The hook material is nested within the pocket structure, which protects it during washing cycles. This nesting arrangement allows the outer shell to be reused and washed multiple times while the hook material remains intact and functional for repeated insert attachments.
