Off-Center Water Supply With Collision Wall for Compact Flush Toilet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flush toilets face challenges in making the design more compact in the forward and backward direction, and the structure on the upstream side of the water supply portion is prone to hanging down due to protrusions.
Innovation Solution
The flush toilet design includes a water conduit with a first and second water-guiding portion, where the water supply portion is positioned off-center, and a collision wall is integrated to redirect flush water, allowing for adjustable distribution ratios and preventing the structure from hanging down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the water supply portion is shifted from the central position to a right-sided or left-sided position to make the flush toilet more compact in the forth and back direction, then the forward projection of the flush toilet is reduced, but the structure on the upstream side of the water supply portion is prone to hanging down
Solution Approach 1:
The collision wall is configured to redirect water flow from a forward direction into lateral directions (right and left sides). This dimensional redirection of water flow allows the water supply portion to be positioned off-center without creating rearward protrusions, as the collision wall effectively transfers the water flow energy from the forward axis to lateral axes, maintaining structural stability while achieving compact forward projection
Solution Approach 2:
The collision wall acts as an intermediary element between the water supply portion and the water-guiding portions. It receives water flow from the forward direction and redirects it laterally, serving as a mediator that enables the off-center positioning of the water supply portion without causing structural instability. The collision wall absorbs and redistributes water flow forces, preventing the hanging down problem while maintaining the compact design
2Length of moving object
If the water supply portion is positioned off-center to achieve a compact design, then the forward projection is smaller, but the water flow distribution to the first and second water-guiding portions becomes uneven
Solution Approach 1:
The collision wall is designed with specific local geometries and orientations to create different flow conditions for the first and second water-guiding portions. By adjusting the local shape, size, and angular orientation of the collision wall surfaces, precise control over water flow distribution is achieved, ensuring that each water-guiding portion receives the appropriate amount of water flow despite the off-center positioning of the water supply portion

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables a more compact flush toilet in the forward and backward direction while ensuring the structure does not hang down, with adjustable water distribution ratios and smooth water guidance.
Implementation Method 1
a collision wall is provided on a way of the first water-guiding portion such that at least a part of the flush water supplied from the water supply portion toward the first water-guiding portion collides with the collision wall

AI summary
The water conduit has: a first water-guiding portion extending from a water supply portion, where the flush water is supplied to the water conduit, to a first spout port located on one of right and left sides of the bowl portion; and a second water-guiding portion extending from the water supply portion to a second spout port located on the other side. The water supply portion is located at a position on the one side. The flush water is supplied to the water supply portion in a direction from the water supply portion toward the first water-guiding portion. A collision wall is provided on a way of the first water-guiding portion such that at least a part of the supplied flush water collides with the collision wall. The at least part of the flush water having collided with the collision wall is supplied to the second water-guiding portion.
