Solution Overview

Problem

Existing floor drains suffer from blockage issues and odor backflow, with existing solutions either failing to address both problems effectively or complicating maintenance and cleaning processes.

Innovation Solution

A vertical-drainage floor drain design featuring a base, drainage cover, and cover plate, with a drainage pipe, channel, and outlet, allowing for easy detachment and cleaning, and incorporating a siphon mechanism to prevent odor backflow and facilitate rapid drainage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a floor drain is designed to intercept sewage and prevent blockage, then anti-blocking performance is improved, but odor backflow prevention capability is insufficient

Engineering Contradiction:

Improveanti-blocking performanceVSAvoidodor backflow

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The floor drain is divided into multiple detachable components including a drain body, cover plate, and drainage cover. This segmentation allows each component to be optimized for specific functions - the cover plate with cross bars for intercepting hair and debris, while the drain body contains the siphon mechanism for odor prevention, enabling both anti-blocking and odor backflow prevention capabilities

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A siphon structure is introduced as an intermediary mechanism between the drainage system and the indoor environment. The siphon uses water seal to block odor gases from the sewage pipe while still allowing wastewater to drain through, effectively preventing odor backflow without compromising drainage functionality

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-generated harmful factors

If a floor drain uses a complex structure to prevent odor backflow, then odor prevention is improved, but ease of cleaning and maintenance deteriorates

Engineering Contradiction:

Improveodor backflow preventionVSAvoidease of cleaning

Core Design Contradiction:

Object-generated harmful factorsVSEase of operation

Solution Approach 1:

The floor drain components are designed to be detachable from each other, with the cover plate and drainage cover able to be easily removed from the drain body. This segmentation transforms the complex odor prevention structure into modular units that can be separately cleaned and maintained, significantly improving ease of cleaning while maintaining effective odor backflow prevention

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The siphon structure is integrated into the detachable drain body, allowing the entire odor prevention mechanism to be extracted and cleaned separately from the installation site. This extraction principle enables thorough cleaning of the siphon and drainage channel without requiring demolition or complex disassembly, maintaining odor prevention effectiveness while simplifying maintenance

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If a floor drain intercepts hair and debris effectively, then anti-blocking performance is improved, but drainage speed may be reduced

Engineering Contradiction:

Improveanti-blocking performanceVSAvoiddrainage speed

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The cover plate is designed with cross bars at specific locations and spacing to intercept hair and debris effectively, while the drainage cover and drain body provide unobstructed vertical drainage pathways. This local quality differentiation ensures that interception occurs only where necessary (at the surface level) while maintaining high drainage speed through the optimized flow path in the drain body

Inventive Principle:

Principle #3Local quality
