Flushable Removable Diaper Liner With Break-Away Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable diapers are often disposed of in landfills, contributing to carbon emissions and potential groundwater contamination due to improper disposal of solid waste, and current flushable liners are not user-friendly.
Innovation Solution
A flushable removable diaper liner with a break-away frame, tabs, and adhesive attachments is designed to be added to existing diapers, allowing easy disposal of solid waste in a flushing toilet, preventing landfill entry and using biodegradable materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If disposable diapers are disposed of in landfills, then solid waste is contained, but carbon emissions increase and groundwater contamination risk occurs
Solution Approach 1:
The diaper system is segmented into two parts: a reusable outer diaper and a removable inner liner. The liner contains the solid waste and can be separately removed and flushed, separating the waste disposal function from the diaper disposal function. This allows the diaper to be reused while the liner with waste is disposed of through flushing, reducing both landfill carbon emissions and preventing groundwater contamination.
Solution Approach 2:
The solid waste containment function is extracted into a separate removable liner that can be taken out from the diaper. This liner is designed to be flushed down the toilet, extracting the waste disposal process from the traditional landfill route and enabling proper sewage system processing instead.
2Object-affected harmful factors
If instructions are provided to shake or dunk diapers in toilet, then solid waste disposal is improved, but user compliance remains low due to inconvenience
Solution Approach 1:
The diaper is segmented into a reusable outer portion and a removable inner liner. The liner is designed with tabs and adhesive features that enable easy removal and flushing. This segmentation makes the waste disposal process simple and intuitive, significantly improving user compliance compared to traditional methods requiring shaking or dunking.
Solution Approach 2:
The liner is designed to be self-removable and self-flushable. The adhesive attachment means and tab structure allow the liner to be easily pulled out and flushed without requiring manual manipulation or special techniques, making the process as simple as removing and flushing a toilet paper roll.
3Object-affected harmful factors
If flushable liners are made available, then waste disposal is improved, but existing liners are not user-friendly and easy to use
Solution Approach 1:
The liner is segmented with distinct functional zones: adhesive attachment areas for securing to the diaper, tab extensions for easy gripping and removal, and a mesh body for waste containment. This segmentation makes each interaction point intuitive and easy to use, significantly improving user-friendliness.
Solution Approach 2:
The tabs act as intermediaries between the user's hand and the liner body. By providing extended gripping surfaces, the tabs mediate the removal action, making it easier for users to grasp and pull the liner out without directly handling the waste-containing mesh portion.
4Object-affected harmful factors
If a removable liner is added to existing diapers, then waste disposal capability is improved, but device complexity increases
Solution Approach 1:
The diaper system is segmented into modular components: the original diaper and the added liner. The liner itself is segmented with adhesive zones and tab extensions. This modular segmentation allows the liner to be a simple add-on component rather than a complex integrated system, minimizing overall device complexity while improving waste disposal capability.
Solution Approach 2:
The liner is designed as a universal component that can be attached to various types of existing diapers using adhesive means. The same liner design works with different diaper brands and styles, reducing the need for multiple specialized components and thereby reducing overall system complexity.
