Ceramic Sanitary Ware Separate Liquid Foam Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional toilet bowls consume large amounts of water, leading to wastage, and existing foam sealing systems face issues with pipe corrosion, low foam supply speed, and uneven distribution, resulting in poor cleaning and odor escape.
Innovation Solution
A sanitary ware design featuring separate ceramic liquid and foam channels that are not communicated, with dedicated inlets and outlets, and a deodorizing device, allowing for simultaneous and efficient water and foam flushing without pipe obstruction, and automatic foam generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal pipe is added for transporting foam, then foam can be supplied to the sanitary ware, but the pipe will get blocked due to long-term corrosion
Solution Approach 1:
The patent replaces the metal pipe with a ceramic channel that is integral to the sanitary ware body. The ceramic material is chemically inert and does not corrode, eliminating the blocking problem while maintaining structural integrity and durability in the wet environment.
Solution Approach 2:
The patent uses ceramic material for the foam and liquid channels, combining the advantages of corrosion resistance with the ability to form complex geometries. This material choice eliminates the corrosion issue inherent in metal pipes while maintaining structural strength.
2Device complexity
If water and foam are supplied through one channel, then the structure is simpler, but the foam supply speed is low and distribution is uneven
Solution Approach 1:
The patent divides the single channel into two separate channels: one dedicated to water supply and another dedicated to foam supply. This segmentation allows each channel to be optimized for its specific fluid, enabling faster and more uniform foam distribution without interference from water flow.
Solution Approach 2:
The patent provides different channel characteristics for water and foam flow. The foam channel is designed with specific outlet configurations that ensure even distribution, while the water channel is optimized for rapid flow. Each channel has local properties tailored to its specific function.
3Quantity of substance
If traditional toilet bowl is used, then water consumption is high, but this results in wastage of water resource
Solution Approach 1:
The patent uses hydraulic principles by introducing foam into the sewage cavity to facilitate rapid discharge. The foam acts as a flushing medium that accelerates waste removal, reducing the total volume of water needed compared to traditional water-only flushing systems.
