Resilient Mounting Console for Sewer Pipe Equipment Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powered equipment for sewer pipes, such as rat traps, face installation challenges due to space requirements for power sources, often necessitating partial installation outside the pipe or large pipe cross-sections, which can allow rats to bypass the trap.
Innovation Solution
A method involving a resilient cylindrical member with a console for mounting powered equipment, allowing it to be installed inside the sewer shaft by compressing and expanding to fit within the pipe, ensuring space for the equipment while maintaining rat passage functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If powered equipment is installed in sewer pipes, then the equipment can monitor or exterminate rats, but the space required for power sources forces installation outside the pipe or requires large pipe cross-sections
Solution Approach 1:
The resilient cylindrical member is inserted into the sewer pipe, and the powered equipment is mounted on the console attached to this member. The member expands to fit within the pipe's inner cross-section, nesting the equipment inside the pipe rather than requiring external installation or large pipe dimensions.
Solution Approach 2:
The resilient cylindrical member transitions from a compressed state during insertion to an expanded state during operation. This dynamic transformation allows the member to be inserted through smaller openings and then expand to provide sufficient mounting space for the powered equipment within the pipe.
2Ease of operation
If openings are provided in the pipe for equipment entry, then powered equipment can be installed, but rats can bypass the trap through these openings
Solution Approach 1:
The resilient cylindrical member with mounted equipment is nested inside the sewer pipe, eliminating the need for separate openings. The equipment is delivered through the pipe opening in a compressed state and then expands to fit within the pipe, maintaining the pipe's integrity and preventing rat bypass.
Solution Approach 2:
The resilient cylindrical member is pre-compressed to a smaller diameter before insertion, allowing it to pass through the pipe opening. After insertion, it automatically expands to its operational diameter, ensuring the opening remains sealed and effective against rats.
3Ease of operation
If the resilient cylindrical member is compressed for insertion, then it can be inserted into the pipe, but the equipment must be mounted before compression
Solution Approach 1:
The powered equipment is mounted on the console attached to the resilient cylindrical member before the compression and insertion process. This preliminary mounting simplifies the overall installation sequence, as the equipment remains securely attached during compression and insertion, eliminating the need for post-installation equipment attachment.
