Diaper With Concealed Hook Fasteners And Stretchable Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reusable diapers are inadequate for containing waste, do not stay in place, and require a full change regardless of soiling level, leading to wasted time and effort, as well as unnecessary laundering and premature wear of unsoiled parts.
Innovation Solution
A diaper design featuring a removable pocketed sling with concealed hook and loop fasteners, stretchable covers to secure the sling, and a removable absorbent pad, allowing for partial component changes based on soiling, with the sling and pad being detachable for laundry and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional reusable diapers are used, then the diaper provides full coverage and containment, but the entire diaper must be changed and laundered regardless of soiling level, leading to wasted time and premature wear
Solution Approach 1:
The diaper system is divided into separable components: an outer diaper shell and an inner absorbent insert with fastening mechanisms. This segmentation allows the absorbent insert to be removed and replaced independently from the outer shell, enabling partial changes when only the insert is soiled, thus improving changing efficiency and reducing time loss.
Solution Approach 2:
The design enables selective discarding of only the soiled absorbent insert while retaining and reusing the clean outer diaper shell. This selective replacement approach recovers the unsoiled portions of the diaper, extending its usable life and reducing the frequency of complete diaper changes and laundering cycles.
2Ease of manufacture
If conventional reusable diapers are used, then the diaper provides full coverage, but unsoiled portions undergo unnecessary laundering and experience premature wear
Solution Approach 1:
By segmenting the diaper into a reusable outer shell and a removable absorbent insert, the design allows only the soiled insert to be laundered while the outer shell remains clean and reusable. This reduces overall laundry effort and minimizes wear on the unsoiled outer portions of the diaper.
Solution Approach 2:
The system enables recovery and reuse of the unsoiled outer diaper shell by separating it from the soiled absorbent insert. This selective recovery approach reduces unnecessary laundering of clean portions and extends the service life of the outer shell, thereby reducing material loss and wear.
3Reliability
If the diaper uses visible hook and loop fasteners, then the sling can be securely attached, but the fasteners are visible and may cause discomfort or snagging
Solution Approach 1:
A stretchable cover material is introduced as an intermediary layer between the hook fasteners and the external environment. This cover conceals the fasteners, preventing them from snagging on external objects, while still allowing the loop fasteners to engage with the hook fasteners securely underneath, thus maintaining attachment reliability while eliminating comfort and snagging issues.
Solution Approach 2:
The use of a stretchable cover film over the fastening mechanisms provides a smooth, flexible surface that conceals the rigid hook and loop fasteners. This thin film layer prevents snagging on external objects while allowing the underlying fasteners to function securely, thus resolving the contradiction between attachment reliability and comfort.
