U-Shaped Suction Tube for Water Pipe Valveless Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterpipes face issues with high resistance to draught, leakage, and cumbersome assembly, which affect the smoking experience and hygiene, especially due to the use of valves that require significant suction force and manual filling, making them difficult to handle and clean.
Innovation Solution
A waterpipe design featuring a U-shaped end piece of the suction tube that reaches the water surface, eliminating the need for a high-suction valve and allowing smoke to enter the liquid medium in fine bubbles, reducing resistance and improving cleaning, with a modular structure for easier assembly and cleaning, and a click-fastening mechanism for container connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve is used in the suction tube to prevent liquid leakage, then liquid leakage is prevented, but the resistance to draught increases significantly
Solution Approach 1:
The invention removes the valve component from the suction tube entirely. Instead of using a valve to prevent liquid leakage, the system relies on the liquid level in the container and the U-shaped bending of the suction tube to naturally prevent liquid from reaching the tube opening, thereby eliminating the high resistance to draught that valves create.
Solution Approach 2:
The U-shaped bending of the suction tube acts as an intermediary barrier. The liquid level in the container serves as a natural seal, preventing liquid from traveling up the suction tube without requiring a mechanical valve. This intermediary approach maintains reliability while preserving ease of operation.
2Reliability
If a non-return valve is arranged in the base region of the upper container, then liquid entering the suction tube is prevented, but the smoke can only flow into the upper container once corresponding suction force has been applied
Solution Approach 1:
The invention removes the non-return valve from the upper container base region. Instead, liquid ingress prevention is achieved through the U-shaped bending of the suction tube and the liquid level in the container, which naturally block liquid from entering the tube without requiring high suction force to initiate smoke flow.
Solution Approach 2:
Instead of using a valve mechanism that requires overcoming resistance to open, the invention inverts the approach by using the liquid level itself as the sealing mechanism. The liquid naturally seals the tube opening when not in use, and smoke flow begins immediately when suction is applied without needing to overcome valve resistance.
3Object-affected harmful factors
If the suction tube extends deep into the liquid medium, then smoke cleaning is improved, but the risk of liquid entering the suction tube increases
Solution Approach 1:
The suction tube is bent into a U-shape, creating a curved path that extends into the liquid medium for effective smoke cleaning. The U-shaped curvature allows the tube to reach deep into the liquid for bubble formation and cleaning, while the bend itself acts as a barrier preventing liquid from traveling up the tube and entering the electronic system.
Solution Approach 2:
The U-shaped bend of the suction tube serves as an intermediary barrier between the liquid medium and the electronic system. This curved section allows the tube to access the liquid for cleaning purposes while the bend geometry prevents liquid from reaching the tube opening and entering the device.
4Ease of manufacture
If the housing is assembled from several parts, then manufacturing and cleaning are facilitated, but the assembly becomes cumbersome and leakage points increase
Solution Approach 1:
The housing is divided into multiple modular parts including the upper container, lower container, and electronic system housing. This segmentation facilitates manufacturing and cleaning by allowing each component to be produced and cleaned separately, while the modular design with integrated connections reduces the number of separate connection points that could leak.
Solution Approach 2:
The suction tube is integrated directly into the housing structure, merging the tube connection with the housing assembly. This reduces the number of separate connection points and potential leakage sites while maintaining the modular benefits of segmented housing parts for manufacturing and 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 U-shaped closure unit significantly reduces draught resistance, enhances smoke cleaning, and improves the overall smoking experience while ensuring better hygiene and ease of use, with enhanced stability and visual indication of tobacco flavor.
Implementation Method 1
the smoke effectively enters the liquid in small bubbles and rises in it, releasing harmful substances into the liquid medium
Implementation Method 2
The fine bubbles result in a considerably larger surface area of the smoke bubbles, and thus a better 'cleaning' of the smoke
Implementation Method 3
the closure unit is formed as an end piece of the suction tube that is bent into a U-shape... there is no need for a valve requiring a high suction force
