Curved Sewer Trap Housing to Block Rodent Pipe Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to effectively prevent rodents and insects from entering premises through sewer pipes and plumbing, particularly as they can maneuver around conventional trap zones by biting or gripping edges.
Innovation Solution
An animal reverser device with a trap zone and curbed coupling zone is installed on sewer tubing, featuring a tubular connection pipe with a protruding housing and a curved edge to prevent animals from entering, using air holes to attract and trap insects and a curbed design to deter rodents from biting edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional trap zone is created by piping protruding into the housing, then insects can be trapped effectively, but rodents can still enter by biting or gripping the edges of the pipe openings
Solution Approach 1:
The patent applies curvature by replacing sharp pipe edges with a curved coupling zone. The curved surface eliminates grip points for rodents, preventing them from biting or gripping the pipe opening to enter the premises, while still allowing the trap zone to function for insects.
Solution Approach 2:
The patent applies local quality by creating different surface characteristics in different zones: the trap zone maintains its original structure for insect trapping, while the coupling zone features a curved surface specifically designed to prevent rodent access. This localized modification addresses the rodent problem without compromising insect trapping effectiveness.
2Stability of the object's composition
If the pipe opening edge is made available for structural support, then the connection is stable, but rodents can use this edge to bite and maneuver into the premises
Solution Approach 1:
The curved coupling zone replaces the sharp edge that provided structural support for connection while simultaneously serving as a grip point for rodents. The curved surface maintains connection integrity through its geometric form while eliminating the biting edge that rodents exploit for access.

AI summary
An animal reverser device can include a housing containing a trap zone adapted to prevent animals from entering a premises via sewer-related tubing. A first tubular connection pipe can connect to drain piping and can protrude downward into the housing. An area formed around the outer surface of the first tubular connection pipe within its protrusion within the housing can create the trap zone. A second tubular connection integrated with a bottom of the housing and protruding downward from the housing can be connected to an existing drain trap or sewer line pipe that carries waste away from the premises.
