Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing quick-cleaning mechanisms for floor drains require manual intervention for debris removal, posing a risk of direct contact with dirty debris during cleaning, and are not cost-effective.

Innovation Solution

A quick-cleaning floor drain with a quickly replaced cleaning part, featuring a disposable quick-cleaning member connected to an extraction rod via magnets or engaging mechanisms, allowing for easy detachment and replacement without manual handling of debris.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual intervention is used for debris removal in quick-cleaning mechanisms, then cleaning can be performed, but cleaning personnel come into contact with dirty debris

Engineering Contradiction:

Improvecleaning operationVSAvoidcontact with dirty debris

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the harmful debris from the cleaning process by using a disposable quick-cleaning member that captures debris during normal operation. The member with attached debris is removed as a complete unit through the quick-cleaning mechanism, allowing debris to be taken out without manual contact.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a disposable quick-cleaning member that is inexpensive and designed for single-use. After capturing debris, the entire member is discarded rather than cleaned manually, eliminating the need for personnel to handle dirty debris while maintaining effective cleaning functionality.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Productivity

If traditional cleaning mechanisms are used, then debris can be removed, but cleaning time is extended and requires manual handling

Engineering Contradiction:

Improvecleaning efficiencyVSAvoidcleaning time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The quick-cleaning member performs preliminary action by continuously capturing and accumulating debris during normal floor drain operation. This preliminary debris collection eliminates the need for time-consuming manual cleaning operations, as the debris is already gathered and ready for removal when needed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cleaning function is segmented into a separate, removable quick-cleaning member that operates independently from the main floor drain structure. This segmentation allows the debris-capturing component to be quickly extracted and replaced without time-consuming disassembly of the entire drain system.

Inventive Principle:

Principle #1Segmentation

3Ease of manufacture

If reusable cleaning components are used, then cost is reduced, but cleaning personnel must manually handle and clean debris

Engineering Contradiction:

Improvecost-effectivenessVSAvoiddebris handling

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent uses inexpensive disposable quick-cleaning members that are economical to manufacture and replace. Although single-use, their low cost makes them more effective than reusable components that require manual cleaning, as the disposal process eliminates harmful debris handling while maintaining cost-effectiveness.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

Instead of cleaning and reusing the same component, the patent implements a discard-and-replace system where the disposable member with captured debris is removed and disposed of as a unit. This approach recovers the time and effort that would be spent on manual cleaning while maintaining economic viability through low-cost disposable components.

Inventive Principle:

Principle #34Discarding and recovering
