Toilet Siphon Solids Packaging for Odorless Sewage Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sewage systems struggle with the efficient separation and disposal of solid excrement and toilet paper, leading to contamination and high operational costs, while current solutions are either unsuitable for decentralized systems or inefficient in resource recovery.
Innovation Solution
A method and device for separating solids from wastewater downstream of the toilet siphon, packaging them in hermetically sealed bags for separate disposal, using a system that can be installed behind a modern toilet to ensure odorless and reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solids are separated downstream of the siphon using a packaging device, then the burden on sewage systems is reduced and contamination is minimized, but the device complexity increases
Solution Approach 1:
The packaging device is nested within the existing toilet cistern structure, utilizing the available space behind the toilet bowl. The hose roll, packaging mechanism, and sealing components are compactly arranged within the cistern compartment, integrating the solids separation function without requiring separate external equipment.
Solution Approach 2:
The system uses the existing flushing water from the toilet as the transport medium to carry packaged solids through the sewage system. The siphon effect of the existing toilet bowl is utilized to create the necessary flow without additional pumps or energy input. The packaging hose is automatically advanced and sealed by the flushing action itself.
2Loss of substance
If flushing water is used as transport medium, then water resources are conserved, but the quantity of substance to be treated in sewage systems increases
Solution Approach 1:
The system recovers and reuses the flushing water that would otherwise be wasted down the drain. By using this water as the transport medium for packaged solids, the system maximizes the utility of each flush, converting waste water into a functional resource for solids transport without requiring additional water consumption.
3Object-generated harmful factors
If hermetically sealed bags are used for solids packaging, then odor control is improved and separate disposal is enabled, but the manufacturing precision requirements increase
Solution Approach 1:
The system uses disposable packaging hoses that are inexpensive and single-use. Each flush creates a new sealed package that is discarded with the solids, eliminating the need for expensive, reusable sealing mechanisms. The simplicity of the disposable hose design reduces manufacturing precision requirements while maintaining effective odor control.
4Ease of operation
If solids are packaged in individual bags, then separate disposal is facilitated, but the device complexity and operational costs increase
Solution Approach 1:
The packaging and sealing operation occurs periodically with each flush cycle rather than continuously. The hose is advanced, sealed, and filled in discrete steps synchronized with the toilet flushing pattern, simplifying the control mechanism and reducing the complexity of continuous packaging systems.
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 system effectively separates and packages solid waste for disposal, reducing the burden on sewage systems, minimizing contamination, and conserving water resources by using the flushing water as a transport medium, thus lowering operational costs and environmental impact.

AI summary
According to said method, the solids are packaged together with some air into individual bags (63) formed from a continuously supplied tube, and the buoyant bag (63) is hermetically sealed and released into the sewage system. The corresponding device contains, downstream of the siphon of the toilet (100), at least the following technical components for handling the siphon discharge within a closed system: • a solids removal tank (3) for collecting the solids; • a solids pump (28) for conveying the removed solids upward in a riser pipe (4) into an elevated solids tank (5); • a portioning apparatus (6) having a metering valve (7) for dropping solids portions into a tubular-bag packaging unit (9) located therebelow; • a tubular-bag packaging unit (9) for producing, from a continuously supplied tube, bags (63) which are hermetically sealed and then separated and which contain solids and some air, for discharge into the sewage system.
