Closestool Base Open Water Draining Channel Insect Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closestool bases face challenges in automatic inner wall cleaning, as water stains and dirt accumulation in closed water draining passages make them difficult to clean, and hidden passages can harbor insects, compromising sanitation.
Innovation Solution
A closestool base design featuring an open water draining channel, a water flowing pipe with a water storage cavity, and a semicircular water baffle plate with vertical ribs, allowing for efficient water distribution and automatic cleaning of the inner wall, eliminating the need for closed passages and reducing insect infestation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a closed water draining passage is used to achieve automatic cleaning, then the inner wall can be cleaned automatically, but water stains accumulate and dirt hides in the passage making it difficult to clean
Solution Approach 1:
The patent extracts the water outlet from the closed passage structure and positions it at the upper edge of the inner wall, allowing the passage to be open rather than enclosed. This enables automatic cleaning functionality while making the passage accessible for manual cleaning of accumulated dirt and water stains.
Solution Approach 2:
The water draining system is segmented into distinct functional zones: an open water draining passage for accessibility, a washing water outlet hole positioned at the upper edge for automatic cleaning, and a water storage cavity. This segmentation allows each component to fulfill its function without compromising the others.
2Shape
If the washing water outlet hole is hidden in the inner side of the water draining passage for aesthetics, then appearance is improved, but the closestool becomes more difficult to clean
Solution Approach 1:
The water outlet hole is positioned at the upper edge of the inner wall rather than being hidden within the passage. This local positioning provides aesthetic integration while maintaining accessibility for cleaning, as the outlet is exposed at a reachable location rather than concealed deep within the passage structure.
3Loss of substance
If no water exists in the draining passage, then water consumption is reduced, but insects can climb in from the washing water outlet hole
Solution Approach 1:
The patent introduces a water seal mechanism where water stored in the water storage cavity acts as an intermediary barrier. This water seal prevents insects from climbing up the open water draining passage from the washing water outlet hole, while allowing the passage to remain open and accessible for cleaning.
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 ensures easy cleaning, reduces water consumption, and effectively prevents insect infestation, while maintaining structural durability and simplicity, enhancing the flushing and dirt discharge capabilities with reduced water usage.
Implementation Method 1
water enters into the water draining passage from the water tank and then flows out from a washing water outlet hole
Implementation Method 2
the water storage cavity is arranged between the water outlet of the water flowing pipe and the water inlet of the water flowing pipe
Implementation Method 3
an open water draining channel is adopted for taking the place of a closed water draining passage, so that the closestool is convenient to clean, and insect pests such as cockroaches cannot be hidden in the closestool
