Toilet Biodegradation Container Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microbial toilets face issues with large size, inconvenient operation for replacing microbial degradation bacteria strains, and the problem of water flushing into biodegradation tanks, which can harm the microbial activity and increase the occupied area.
Innovation Solution
A toilet design with a biodegradation container movably disposed within a holding cavity, featuring a mixing portion and driving mechanism for easy replacement of biodegradation materials, and a liquid collection tray to prevent water from entering the biodegradation tank, separating urine and feces for efficient decomposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the toilet base is made large to accommodate the biodegradation tank, then the biodegradation function is improved, but the occupied area increases
Solution Approach 1:
The toilet base is divided into a fixed base structure and a movable biodegradation tank. The tank can be detached and moved independently, allowing the base to maintain a compact size while the tank provides the necessary biodegradation volume. This segmentation resolves the contradiction by separating the structural support function (base) from the biodegradation function (tank).
Solution Approach 2:
The biodegradation tank is designed to be movable rather than fixed, allowing it to be repositioned or removed when needed. This dynamic design enables the system to maintain a small occupied area while still providing adequate biodegradation capacity, as the tank can be adjusted based on usage requirements.
2Ease of operation
If the biodegradation tank is made detachable for easy replacement of microbial strains, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The biodegradation tank is segmented from the main toilet structure, allowing it to be detached as a separate unit. This segmentation enables easy replacement of microbial strains by simply removing and replacing the tank, without affecting other components of the toilet system.
Solution Approach 2:
The movable connection structure between the base and tank is designed to serve multiple functions: it provides structural support when attached, enables easy detachment for replacement, and maintains alignment during operation. This multi-functionality reduces the need for separate complex mechanisms.
3Manufacturing precision
If water flushing is used to clean the toilet, then the cleanliness is improved, but the microbial activity in the biodegradation tank is harmed
Solution Approach 1:
The liquid collection tray is extracted as a separate component that can be independently positioned. When the tray is in the first position, it collects liquid waste separately from the biodegradation tank. When in the second position, it allows liquid to flow into the tank for biodegradation. This extraction enables the system to maintain cleanliness without harming microbial activity.
Solution Approach 2:
The liquid collection tray is designed to be movable between two positions, allowing the system to dynamically switch between liquid collection mode and biodegradation mode. This dynamic positioning enables the toilet to maintain cleanliness during use while still allowing water to reach the microbial strains when needed for decomposition.
