Solution Overview

Problem

Cleanout caps for sewer systems require manual removal for maintenance assessment, leading to inefficiency and potential sewage spillage, with maintenance history often unavailable.

Innovation Solution

A smart sewer cleanout cap equipped with a wireless identification tag, such as RFID or NFC, that provides real-time maintenance data and allows secure, watertight sealing, enabling remote assessment and reducing spillage through a clamp assembly and transparent window plug.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If manual removal of cleanout cap is performed to assess maintenance needs, then maintenance history information can be obtained, but the process is tedious and time-consuming

Engineering Contradiction:
Improvemaintenance history availabilityVSAvoidtime for maintenance assessment
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical action of manually removing the cleanout cap with an electronic information retrieval system. An RFID tag embedded in the cap stores maintenance history, which can be read wirelessly by a scanner, eliminating the need for physical cap removal and providing instant access to maintenance information.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a digital copy of the maintenance history information and stores it on an RFID tag attached to the cleanout cap. This digital replica allows rapid retrieval of maintenance data without requiring physical inspection or removal of the cap, significantly reducing assessment time.

Inventive Principle:
Principle #26Copying

2Difficulty of detecting and measuring

If cleanout cap is removed to check sewer drainage, then drainage condition can be assessed, but raw sewage can spill on the ground creating environmental issues

Engineering Contradiction:
Improvesewer drainage visibilityVSAvoidsewage spillage
Core Design Contradiction:
Difficulty of detecting and measuringVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical action of removing the cap for visual inspection with an electronic information system. Maintenance history and drainage status are stored on an RFID tag and can be retrieved wirelessly, allowing assessment of sewer conditions without opening the system and risking sewage spillage.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an RFID tag as an intermediary that carries information about the sewer drainage status. Instead of directly observing the drainage by removing the cap, the RFID tag mediates the information transfer, allowing indirect assessment without environmental contamination risk.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If secure sealing is implemented to prevent sewage spillage, then environmental safety is improved, but the device complexity increases

Engineering Contradiction:
Improvesewage spillage preventionVSAvoidcleanout cap structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical sealing mechanisms with an electronic information system. By storing maintenance history and drainage status on an RFID tag, the system eliminates the need for frequent cap removal and reinstallation, reducing the demand for complex sealing mechanisms while still preventing spillage during normal operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
