Flushable Diaper Waste Chamber for Reusable Hygiene Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bodily waste management systems, including diapers and bedpans, are inadequate in terms of hygiene, comfort, environmental impact, and efficiency, often leading to skin irritations, infections, and excessive waste generation, while also being cumbersome and difficult to use, especially in environments like space travel.
Innovation Solution
A reusable, flushable diaper system with a built-in flushing system that captures, contains, and disposes of both urine and feces, featuring a closed design with rigid materials and non-invasive seals, allowing for use in various positions and environments, including zero gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If disposable diapers are used, then convenience and ease of use are improved, but environmental harm and landfill waste increase
Solution Approach 1:
The diaper system enables recovery and reuse of the diaper components after waste removal. The rigid shell and flexible membrane are designed to be cleaned and reused multiple times, replacing the single-use disposable model while maintaining convenience through the flushable waste collection chamber.
Solution Approach 2:
The waste collection chamber is extracted as a separate removable component that can be flushed or emptied independently. This allows the main diaper body to be reused while the waste containment portion is easily disposed of or cleaned, combining reusable and disposable aspects.
2Reliability
If traditional diapers are used, then waste capture is achieved, but skin contact with waste occurs causing irritations and infections
Solution Approach 1:
A flexible membrane creates a barrier between the user's skin and the waste collection chamber. This membrane allows the diaper to conform to the body while preventing direct contact with feces and urine, eliminating skin irritations and infections while maintaining reliable waste capture.
3Object-generated harmful factors
If reusable cloth diapers are used, then environmental waste is reduced, but cleaning and sanitization effort increases
Solution Approach 1:
The manual cleaning process is replaced with a flushing mechanism. The waste collection chamber can be emptied by flushing with water through a toilet or sink, significantly reducing the time and effort required for cleaning compared to hand-washing cloth diapers while still being reusable.
Solution Approach 2:
The diaper is segmented into reusable components (rigid shell, flexible membrane) and a removable waste collection chamber. This segmentation allows the bulk of the diaper to be reused without extensive cleaning, as only the waste chamber needs to be flushed or emptied.
4Reliability
If disposable diapers are used frequently, then incontinence management is improved, but cost increases over time
Solution Approach 1:
The diaper system is designed for recovery and reuse of the main components after multiple uses. The rigid shell and flexible membrane can be cleaned and reused many times, replacing the need to continuously purchase disposable diapers and reducing long-term costs while maintaining reliable incontinence management.

AI summary
This invention is an advanced, high-tech, flushable, diaper system that would eliminate the need for parents and caretakers to change diapers in the traditional way, whereby users need to have urine and feces wiped clean from their bodies and used diapers thrown away to be added to landfills or, in cases of reusable cloth diapers, washed at home or sent off to be washed and sanitized professionally. It would improve comfort and cleanliness for many and provide more dignity for the incontinent and bedridden. It would benefit those on long work shifts without bathroom breaks like pilots, astronauts, and surgeons. It would be useful to those in remote locations like distant travelers, skiers, hikers, mountain climbers, and deep sea divers or in harsh environments, where a toilet is not easily accessible like on the battlefield. Versions of this advanced diaper system may also be used for certain animals and pets.
