Low-weight infant diaper belt locking markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-weight infant diapers with attachment pads on the main body portion can irritate delicate skin and make diaper replacement challenging due to increased stiffness and difficulty in locking the belt members at appropriate positions.
Innovation Solution
A low-weight infant diaper design featuring belt members with locking members that directly engage the exterior sheet, eliminating attachment pads and using visible markers on the non-skin-side surface to indicate lock positions, allowing for easy and appropriate locking without increasing stiffness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If attachment pads are provided on the main body portion to enable locking of belt members, then the locking function is improved, but the stiffness of the main body portion increases and may irritate the infant's delicate skin
Solution Approach 1:
The invention extracts the attachment pads from the main body portion and relocates them to the belt members only. This allows the locking function to be maintained while eliminating the stiffness and skin irritation caused by attachment pads on the main body portion. The belt members now carry both the locking and attachment functions.
Solution Approach 2:
The belt members are given multiple functions: they provide both the locking mechanism (via locking members) and the attachment function (via attachment pads on the belt members themselves). This multi-functionality eliminates the need for separate attachment pads on the main body portion, resolving the contradiction between locking reliability and skin comfort.
2Object-affected harmful factors
If attachment pads are eliminated from the main body portion to reduce stiffness, then skin irritation is reduced, but it becomes difficult to know which positions on the exterior sheet are intended for locking
Solution Approach 1:
The invention uses visual markers (different colors or patterns) on the exterior sheet to indicate the intended lock positions. These markers provide clear visual information to caregivers about where to attach the belt members, compensating for the removal of attachment pads from the main body portion and preventing confusion about proper positioning.
3Ease of operation
If the belt members are made detachable for easy replacement in prone postures, then ease of operation is improved, but the time required for detachment and re-locking increases
Solution Approach 1:
The invention positions the attachment pads and locking members in advance at optimal locations on the belt members and exterior sheet. This preliminary arrangement allows caregivers to quickly and accurately attach or detach the diaper without needing to search for proper positions or perform complex adjustments, reducing the time required for diaper replacement while maintaining ease of operation.

AI summary
A low-weight infant diaper (1) includes: an absorbent body (2); an exterior sheet (5); a pair of belt members (20); and a marker (30) . The pair of belt members (20) each includes: a locking member (22) on a one side in a longitudinal direction of the belt member (20) and a locking member (22) on an other side in the longitudinal direction of the belt member (20). The pair of belt members (20) are capable of being locked to a non-skin-side surface of the exterior sheet (5) with use of the locking members (22). The marker (30) indicates a lock position for one or more of the belt members (20) on the non-skin-side surface of the exterior sheet (5). The marker (30) is visible from a non-skin-side surface side of the exterior sheet (5).
