Segmented Sewer Backflow Barrier for Odor and Regurgitation Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water-sewage systems fail to completely prevent unwelcome fluid and gaseous regurgitation phenomena and foul-smelling gaseous efflux emission, with existing solutions only partially addressing the issue.
Innovation Solution
A device comprising a plurality of three-dimensional elements with a circle wedge shape, arranged to form a disk, which bends downwards under gravity and returns to a fixed position, creating a tight adhesion with the sewer system walls to block odors and enhance material flow, using a support with a circular crown for installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If siphon fittings are used to create a liquid fluid plug, then gaseous regurgitation flow is partially blocked, but the solution is not sufficient to completely prevent regurgitation and odor emission
Solution Approach 1:
The device divides the blocking function into multiple independent three-dimensional elements (at least three) arranged around the periphery of the support. Each element can independently bend and return, creating multiple sealing points that collectively provide complete blocking of both liquid and gaseous regurgitation, overcoming the insufficiency of a single siphon fitting
Solution Approach 2:
The three-dimensional elements are designed to be flexible and dynamic, bending downwards under the weight of falling material and automatically returning to their original position. This dynamic behavior allows the elements to adapt to flow conditions while maintaining reliable sealing, ensuring complete prevention of regurgitation and odor emission
2Reliability
If a device with multiple three-dimensional elements is used to completely prevent regurgitation, then reliability of blocking is improved, but the device complexity increases
Solution Approach 1:
Multiple three-dimensional elements are merged into a single functional unit that operates together on a common support structure. The elements work in unison to provide complete blocking, while the unified design allows for simplified manufacturing and installation compared to multiple separate devices
Solution Approach 2:
The three-dimensional elements are made from flexible materials that allow them to bend and return automatically. This flexibility eliminates the need for complex mechanical actuation mechanisms, reducing device complexity while maintaining reliable blocking through the natural elastic recovery of the material
3Productivity
If the three-dimensional elements bend downwards under gravity, then material flow is facilitated, but the risk of regurgitation increases if elements do not return to position
Solution Approach 1:
The elements are designed with dynamic flexibility to bend under gravity during material flow, facilitating smooth passage of solids and liquids. The same dynamic property enables automatic return to the original position after flow passes, maintaining the sealing function to prevent regurgitation and odor emission
Solution Approach 2:
The three-dimensional elements utilize their own elastic properties to automatically return to their original position after bending during material flow. This self-service mechanism eliminates the need for external actuators or power sources, ensuring reliable prevention of regurgitation while maintaining productivity

AI summary
The present invention refers to a device suitable for preventing the phenomena of regurgitation and the emission of bad smells from the water-sewage systems. In particular, the present invention refers to such a device which consists of separate elements joined all together, locked on a circular support, and which are able, first of all, to bend downwards when subjected to the gravity force generated by the solid and/or liquid material falling downwards and, subsequently, to return to the position assumed before bending.
