Sewer Cleanout Cap With RFID Window Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sewer cleanout caps require removal for maintenance assessment, leading to inefficiency and potential environmental hazards due to sewage spillage, as maintenance history and conduit conditions are not readily accessible.
Innovation Solution
A sewer cleanout cap equipped with a radio-frequency identification (RFID) tag and a window plug, allowing for maintenance assessment without cap removal, featuring a body portion made from durable materials like lead or cast iron, and a transparent window for visibility, with the RFID tag storing and transmitting information on installation date, maintenance history, and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleanout cap is removed to check conduit conditions, then maintenance assessment can be performed, but sewage may spill and time is lost
Solution Approach 1:
A transparent window plug is introduced as an intermediary element that allows visual inspection of conduit conditions without removing the cleanout cap. The window provides a direct line of sight into the sewer conduit, enabling maintenance personnel to assess blockages or conditions while the cap remains sealed, preventing sewage spillage.
Solution Approach 2:
The patent replaces the mechanical action of cap removal with an optical inspection method through the transparent window. Instead of physically removing the cap to see inside the conduit, the system uses light transmission through the transparent window to provide visual information about conduit conditions.
2Reliability
If the cleanout cap is removed to determine cleaning needs, then accurate maintenance decisions can be made, but the process becomes tedious and inefficient
Solution Approach 1:
An RFID tag is embedded in the cleanout cap that stores maintenance history and conduit information in advance. Before inspection, the RFID tag already contains relevant data about the conduit's maintenance record and conditions. Maintenance personnel can quickly scan the RFID tag to obtain pre-stored information, eliminating the need for time-consuming manual record searches and enabling faster decision-making.
3Reliability
If the cleanout cap is removed for inspection, then conduit conditions can be assessed, but environmental hazards increase
Solution Approach 1:
The transparent window plug serves as an intermediary that enables conduit condition assessment while maintaining the sealed state of the cleanout cap. By allowing visual inspection through the window, the system eliminates the need to break the seal and remove the cap, thereby preventing sewage from escaping into the environment and reducing environmental pollution.
