Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing toilet flushing nozzle with a venturi effect suffers from particulate matter blocking the negative pressure suction part, leading to insufficient usage of sealing water and weakened flushing performance.
Innovation Solution
A ceramic pressure-flushing apparatus featuring a lower jet nozzle with a venturi tube and a water supplement structure that uses negative pressure to draw water from a separate mixing area, avoiding direct suction from the toilet bowl and enhancing flushing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the negative pressure suction part sucks sealing water from the water seal recess to increase the forcefulness of the flush, then the flushing force is improved, but the particulate matter in the waste will block the negative pressure suction part, causing insufficient usage of the sealing water
Solution Approach 1:
The water supply path is divided into two separate sources: sealing water from the water seal recess and supplement water from the water supplement structure. The negative pressure suction part only suction supplement water through the water mixing area, avoiding direct contact with waste particles while still achieving enhanced flushing force through the combined water flow.
Solution Approach 2:
The water mixing area acts as an intermediary structure between the negative pressure suction part and the sealing water. It allows the supplement water to be mixed with sealing water before ejection, enabling the system to utilize sealing water for flushing without the suction part being directly blocked by particles.
2Productivity
If the venturi tube creates negative pressure to suction water and increase kinetic energy, then the water flow rate increases, but the particulate matter blocks the suction path reducing the effectiveness
Solution Approach 1:
The supplement water is extracted from a separate water supplement structure rather than being suctioned directly from the water seal recess. This extraction approach removes the harmful factor of particulate matter blockage while maintaining the negative pressure suction mechanism's ability to increase water flow rate and kinetic energy.
Solution Approach 2:
The water mixing area serves as an intermediary that combines supplement water with sealing water. This intermediary structure allows the negative pressure system to maintain high water flow rates without direct blockage from particulate matter, as the supplement water bypasses the potential blockage points.
3Power
If the lower jet nozzle uses a venturi tube with negative pressure port to enhance flushing, then the siphon effect is improved, but the structure becomes more complex
Solution Approach 1:
The venturi tube is nested inside the sleeve tube, and the water mixing area is integrated into the outer peripheral surface of the sleeve tube. The water supplement structure is positioned to communicate with the water mixing area. This nested arrangement enhances the siphon effect while minimizing structural complexity by utilizing existing spaces and integrating multiple functions into a compact 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
The solution increases the volume and kinetic energy of flushing water, improving the siphon effect and maintaining flushing performance even with particulate matter present, by using a separate water supplement structure that is not directly affected by waste from the toilet bowl.
Implementation Method 1
after pressurized water flows into the venturi tube, a negative pressure is formed at the negative pressure port, and water in the water supplement structure is sucked through the water mixing area to be combined with the pressurized water
Implementation Method 2
a venturi tube is installed inside the sleeve tube, and a negative pressure port is formed between an outer wall of the venturi tube and an inner wall of the sleeve tube
Implementation Method 3
A siphon jet toilet is a toilet with further improvement on the siphon toilet
