Spring-Loaded Diaper Holder for One-Handed Diaper Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Changing a child's diaper is a time-consuming and stressful process due to the need for two hands, increasing the risk of infant injuries from sudden movements during the process, as parents cannot maintain a secure hold on the child while preparing and maneuvering the diaper.
Innovation Solution
A diaper tree with a vertical stalk mechanically coupled to a spring-loaded clamp and a platform, allowing for one-handed access and manipulation of diapers, with the platform arms connected by compression springs to maintain consistent outward pressure and hold the diapers in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If parents use two hands to retrieve and prepare diapers, then diaper preparation can be completed, but the ability to maintain a secure hold on the child is lost
Solution Approach 1:
The diaper preparation task is segmented into two independent parts: (1) diaper storage and retrieval handled by the diaper tree device, and (2) child holding handled by the parent. The diaper tree separates the diaper stack into individual units using dividers, allowing the parent to access one diaper at a time with one hand while maintaining control of the child with the other hand.
Solution Approach 2:
The diaper tree acts as an intermediary device between the diaper supply and the parent. It provides a mechanical system (platform, clamp, dividers) that automatically presents individual diapers for retrieval, eliminating the need for the parent to manually handle the entire diaper stack with both hands.
2Ease of manufacture
If parents manually retrieve and unfold diapers, then the process can be completed, but the time required increases
Solution Approach 1:
Diapers are pre-positioned in the diaper tree with the help of dividers that maintain separation and orientation. The platform and clamp system is pre-configured to present diapers in an easily accessible position, so that when a parent needs a diaper, it is already prepared for quick retrieval without manual unfolding or searching.
Solution Approach 2:
The diaper tree incorporates a spring-loaded clamp that can dynamically adjust to hold and release diapers. The platform can move to present different diapers in the stack, and the clamp can quickly grasp or release a diaper with minimal effort, reducing the time required for each retrieval action.
3Device complexity
If a simple diaper storage solution is used, then device complexity is low, but the ability to hold multiple diapers securely is limited
Solution Approach 1:
The diaper tree uses a nested structure where multiple dividers are positioned within the storage container to create individual compartments. Each divider segment helps maintain separation of diapers in the stack, allowing the device to securely hold multiple diapers (large quantity) while the overall structure remains relatively simple and compact (low complexity).
