Flush Toilet Synchronous Water Flow and Siphon Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flush toilets with water-saving functions suffer from poor flushing performance and inefficient waste removal due to delayed and reduced water flow synchronization, leading to a weakened swirling effect and insufficient siphon effect.
Innovation Solution
A flush toilet design featuring a bowl portion with strategically positioned first and second outlet channels, a jet channel, and a partition assembly, where the first and second outlet channels are directed to ensure synchronous water flow and a consistent direction, combined with a jet channel for enhanced siphon effect, optimizing the swirling flow and waste removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the second spray outlet is used to compensate for the deficiency in strength of the first flushing water flow, then the flushing effect is improved, but the second flushing water flow has a longer guided path causing delayed emergence and reduced swirling flow strength
Solution Approach 1:
The water guiding passage is divided into multiple independent segments (first water guiding passage and second water guiding passage) that allow water to flow simultaneously through different paths. This segmentation enables the first and second flushing water flows to emerge at approximately the same time, eliminating the time delay caused by the longer guided path in the previous single-path design.
Solution Approach 2:
The patent introduces a new spatial dimension by adding a second water guiding passage that runs parallel to the first water guiding passage. This dimensional expansion allows water to take alternative paths with different lengths, enabling synchronization of water flow emergence times while maintaining adequate flushing strength through multiple concurrent flows.
2Loss of substance
If water-saving function is implemented with reduced water amount, then water consumption is reduced, but flushing performance and waste removal efficiency deteriorate
Solution Approach 1:
The flushing water is segmented into multiple directed flows (first flushing water flow and second flushing water flow) that target different areas of the bowl portion. This segmentation allows reduced total water quantity to be distributed efficiently across multiple focused streams, maintaining flushing performance while reducing overall water consumption compared to a single undirected flow.
Solution Approach 2:
Different portions of the bowl portion are targeted with specifically directed water flows having different characteristics. The first water guiding passage directs water to one side while the second directs water to the other side, creating locally optimized flushing action that maximizes effectiveness with minimal water usage.
3Area of stationary object
If the second flushing water flow is guided along a longer path to reach the bowl portion, then broader coverage is achieved, but the water flow strength is reduced and swirling effect is weakened
Solution Approach 1:
The water guiding system is segmented into two separate passages, each with optimized path lengths. This allows the first water guiding passage to provide strong localized flushing while the second water guiding passage provides complementary coverage, achieving broad overall coverage without sacrificing the strength of individual flows.
Solution Approach 2:
The first flushing water flow and second flushing water flow are merged to create a combined swirling flow pattern. By combining multiple flows of adequate strength that emerge simultaneously, the system achieves both broad coverage and strong swirling effect, overcoming the limitation of single long-path flows that lose strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances the strength and synchronization of the swirling flow, improving flushing performance and creating a powerful siphon effect for efficient waste removal, even with reduced water usage.
Implementation Method 1
a first water flow and a second water flow rotating in the same direction are combined and working together to have synergistic effect and generate the strongest swirling flow
Implementation Method 2
the third flushing water flow can press the waste under the water quite well and even generate a siphon effect earlier

AI summary
A flush toilet is revealed. The flush toilet includes a bowl portion, a drain pipe, an inlet channel, a first outlet channel, a second outlet channel, and a jet channel. The first and second outlet channels are turned into different directions from diversion area of the inlet channel. The second outlet channel further includes a curved potion for changing the direction of water flow so that the direction of a second water flow out of the second outlet channel and along a shed portion of the bowl portion is consistent with the direction of a first water flow out of the first outlet channel and along the shed portion. Thus the first and second water flows are out almost synchronously throughout the bowl portion and combined to form a swirling flow which interacts with a third water flow from the jet channel to create a siphon effect for better waste removal.
