Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing separating toilets are complex to manufacture, assemble, and disassemble, with numerous components and a structurally complex design, making them costly and difficult to clean.
Innovation Solution
A separating toilet design featuring a simplified structure with a separating insert supported by projections from a transport container, allowing for easy assembly, disassembly, and integration into a stackable system, using a thermosetting plastic material and minimal components for enhanced stability and ease of cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If additional reinforcing components such as supporting plates are used, then the stability of the separating insert is improved, but the device complexity and number of components increases
Solution Approach 1:
The supporting function is merged into the side walls of the transport container itself. The side walls are designed with integrated supporting projections that extend inward to support the separating insert, eliminating the need for separate supporting plates or reinforcing components. This combines the structural support function with the container walls, reducing component count while maintaining stability.
Solution Approach 2:
The transport container's side walls provide self-supporting projections that automatically support the separating insert when the container is assembled. The projections are formed as integral parts of the side walls, requiring no additional components or assembly steps. The container structure serves its own support function, reducing overall device complexity.
2Ease of manufacture
If the separating insert is designed to be self-supporting with recesses, then the ease of manufacture is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The separating insert is segmented with recesses at its peripheral edge that correspond to projections on the container's side walls. This segmentation allows the insert to be supported at discrete points rather than requiring continuous contact, reducing the precision needed for overall alignment while ensuring stable support at critical locations.
Solution Approach 2:
The recesses in the separating insert act as intermediaries that receive and accommodate the projections from the container walls. This intermediary design provides tolerance compensation, allowing for easier manufacturing of both components while maintaining proper alignment and support through the recess-projection interface.
3Adaptability or versatility
If the upper edges of the transport container are kept free, then the adaptability for stacking and covering is improved, but the structural complexity of the container design increases
Solution Approach 1:
The upper edges of the transport container are designed to be free and accessible, allowing the container to serve multiple functions: it can receive covers, accommodate stacked containers, and provide access to the separating insert. This universal design enables the same container structure to fulfill multiple purposes without requiring additional components or complex mechanisms.
Solution Approach 2:
The design extracts the supporting function from the upper edges of the container, removing any structural elements that would interfere with stacking and covering. By taking out the support function from the upper regions and concentrating it in the side wall projections, the upper edges remain free and simple, enabling versatile stacking and covering applications.

AI summary
A separating toilet having a separating insert and at least one first collecting unit for urine and a second collecting unit for feces, wherein the separating insert as a whole is inserted into an opening of a transport container and is supported in the vertical direction on projections that protrude from an inner side of the transport container toward an interior of the transport container.
