Flush Toilet Flow Segmentation for Floating Waste Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flush toilets with large pooled water surfaces face issues with insufficient discharge of floating waste due to strong flush water flows disturbing the surface, leading to inefficient waste removal.
Innovation Solution
A flush toilet design that includes multiple spouting ports to create forward and rearward main flows circulating around the waste receiving surface, dividing the pooled water surface into four regions, ensuring even distribution and preventing surface disturbance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the pooled water surface is made larger to reduce the waste receiving surface area and suppress waste adhesion, then waste adhesion is suppressed, but strong flush water flows only into specific regions and cannot sufficiently discharge floating waste
Solution Approach 1:
The pooled water surface is divided into four regions by a front-rear centerline and a left-right centerline. The spouting ports are arranged to direct flush water into three or more of these four regions, ensuring comprehensive coverage and effective discharge of floating waste across the entire surface.
2Productivity
If strong flush water flows into a specific region on the pooled water surface, then bowl flushing capacity is improved, but the pooled water surface is disturbed and floating waste cannot be sufficiently discharged
Solution Approach 1:
Different regions of the pooled water surface are targeted with flush water from spouting ports arranged at specific locations. The flush water is directed to flow into three or more regions, creating localized flow patterns that maintain overall surface stability while achieving effective waste discharge.
3Loss of time
If flush water flows into three or more regions of the pooled water surface, then floating waste discharge timing is speeded up, but the system complexity increases
Solution Approach 1:
The pooled water surface is segmented into four regions, and spouting ports are strategically arranged to direct flush water into three or more of these regions. This segmentation approach speeds up floating waste discharge timing while maintaining a relatively simple spouting port configuration.
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
Enhances floating waste discharge performance by speeding up the discharge timing and maintaining consistent pressure on the pooled water surface, improving overall waste removal efficiency.
Implementation Method 1
one or more spouting ports that spout flush water along the rim... the main flow of flush water spouted from the spouting port circulates around the waste receiving surface of the bowl and flows, in the beginning of flushing start, into three or more regions of the pooled water surface

AI summary
A flush toilet of the present invention includes a bowl including a waste receiving surface that receives waste, a rim formed on an upper part of the waste receiving surface and a well portion that is formed below the waste receiving surface and in which a pooled water surface is formed, one or more spouting ports that spout flush water along the rim, and a discharge conduit connected to a bottom portion of the bowl, the flush toilet including a configuration where a forward main flow and a rearward main flow of flush water spouted from the spouting ports circulate around a waste receiving surface of a bowl and flow, in the beginning of flushing start, into three or more regions of the pooled water surface divided into four regions.
