Solution Overview

Problem

Non-dispersing cloths accumulate in toilet drains, leading to backups, blockages, and malfunctions in wastewater systems, as existing solutions fail to effectively trap these cloths without obstructing water flow or requiring frequent maintenance.

Innovation Solution

A sizing tool and trapping device system, comprising a strap with adjustable components and hooks, designed to fit various toilet bowl configurations, which determines the optimal size and configuration for each trapway to catch non-dispersing cloths while allowing water to flow freely and preventing the device from being flushed away.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a trapping device is installed to catch non-dispersing cloths, then cloths are trapped effectively, but water flow may be obstructed

Engineering Contradiction:
Improvecloth trapping effectivenessVSAvoidwater flow rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The trapping device is divided into multiple functional components: a strap that conforms to the trapway shape, multiple hooks distributed along the strap for catching cloths, and an adjustable mechanism. This segmentation allows the device to trap cloths effectively while maintaining water flow through the gaps between components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different portions of the strap have different properties - some areas have hooks for cloth capture, while other areas are more open to allow water flow. The strap material itself has specific properties that balance trapping effectiveness with flow permeability, creating local quality variations throughout the device.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If the trapway configuration varies between toilet bowls, then the device must be adaptable to different sizes and shapes, but device complexity increases

Engineering Contradiction:
Improvecompatibility with different toilet bowlsVSAvoidadjustable components and sizing mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The strap is designed to be flexible and adjustable in length, allowing it to adapt to different trapway configurations. The adjustable mechanism enables the device to be customized for various toilet bowl sizes and shapes without requiring multiple different device designs, thus managing complexity while maximizing adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The trapping device is designed as a universal solution that can be installed in various toilet bowl configurations through its adjustable strap and multiple hook arrangements. This multi-functional design allows a single device type to serve multiple toilet bowl sizes and shapes, reducing the need for specialized devices for each configuration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If existing trapping solutions are used, then cloths may be trapped, but frequent maintenance is required

Engineering Contradiction:
Improvecloth trapping functionVSAvoidmaintenance frequency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The trapping device is designed to be easily removable and reinstallable by users without requiring professional maintenance services. The simple strap and hook design allows users to perform their own maintenance by removing the device, cleaning the trapped cloths, and reinstalling it, thereby reducing the need for frequent professional maintenance interventions.

Inventive Principle:
Principle #25Self-service

AI summary

A method, an apparatus and a system for sizing a trapping device for trapping non-dispersing cloths and/or other materials in a toilet bowl and/or a hopper sink are disclosed. A computer device may be used to implement the method for sizing one or more trapping devices for installation at a facility, such as a medical institution. The computer device may be configured to determine a configuration of a trapway for each of one or more toilet bowls and/or hopper sinks at the facility. After determining the configuration, the computer device may determine a size of a trapping device corresponding to the determined configuration of each of the one or more trapways.
