Compact Dry Toilet Seat With Integrated Gravity Waste Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dry toilet systems for separating and treating human faecal matter and urine are bulky and unsafe for young children, making them unsuitable for collective dwellings and family homes, as they require significant space and lack absolute safety features.
Innovation Solution
A compact dry toilet installation with a conveyor belt system integrated into the toilet seat, allowing for gravity separation of liquid effluent and solid waste, featuring a down pipe and a receiving tank within the seat, and a synchronized transfer mechanism to a storage area for composting, eliminating the need for a chamber underneath and ensuring safety by minimizing the distance between the evacuation opening and the conveyor belt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chamber underneath the toilet is provided with conveyor belt and tanks for treating urine and solid waste, then the treatment function is improved, but the installation size increases and requires two-level arrangement
Solution Approach 1:
The conveyor belt and treatment tanks are integrated inside the toilet seat structure itself, nesting the treatment functions within the existing seat volume rather than requiring separate underground chambers. This allows the treatment system to be compact and suitable for single-level installation.
Solution Approach 2:
The invention combines the toilet seat structure with the treatment chamber into a single integrated unit. The seat housing contains both the conveyor belt for solid waste and tanks for liquid effluent treatment, merging multiple functions into one compact installation.
2Manufacturing precision
If the conveyor belt is mounted at a distance from the evacuation opening, then the separation efficiency is improved, but the safety for young children deteriorates due to fall risk
Solution Approach 1:
The conveyor belt is positioned with optimized local spacing - close enough to the evacuation opening (15-35 cm) to ensure child safety, yet sufficiently distant to maintain effective separation between liquid effluent and solid waste through gravity-driven flow paths.
3Quantity of substance
If the down pipe is positioned parallel to the receiving surface, then the liquid collection is improved, but the solid waste evacuation is hindered
Solution Approach 1:
The down pipe is positioned asymmetrically relative to the receiving surface, creating an angled configuration where the pipe's free end extends partially over the surface. This asymmetric arrangement allows liquid to flow efficiently into the pipe while solid waste is deflected onto the conveyor belt for evacuation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compact design allows for single-level installation in homes, reducing the risk of injury to children and efficiently separating and treating waste, while maintaining safety and efficacy in treating human waste without the need for additional space.
Implementation Method 1
a conveyor belt mounted at an angle delimiting, between a bottom part and a top part, a surface for receiving liquid effluent and waste solid, to ensure the separating under gravity of liquid effluent and solid waste
Implementation Method 2
the anterior part of the free end of the down pipe being mounted to lie flush with the receiving surface so as to act as stop abutment for solid waste
Implementation Method 3
a transfer system ensuring the forward movement of the conveyor belt and hence the conveying of solid waste from a receiving area directly below the evacuation opening, towards a storage area
