Floating Straw Intake Structure for Depth-Specific Laminar Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking straws are ineffective in consistently extracting liquids from a specific depth due to turbulent flow and inability to isolate water from different layers, leading to potential premature aging of cells through excessive electrical stimulation.
Innovation Solution
A straw design with a system of openings in the lower part submerged at a predetermined depth to ensure laminar flow and minimal biological activity, featuring radially placed holes or fan-shaped branches connected to a central tube, with an optional silver or gold coating and a floating device to maintain optimal intake depth between 5-15 mm from the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single opening at the end of the straw is used, then the structure is simple, but turbulent flow is created causing liquid from multiple depths to be sucked in
Solution Approach 1:
The single opening at the end of the straw is segmented into multiple openings (first, second, and third openings) positioned at different depths along the straw. This segmentation allows liquid to be drawn from specific depth layers independently, preventing turbulent flow that would mix liquids from multiple depths while maintaining structural feasibility.
2Reliability
If multiple openings at different depths are added to the straw, then depth-specific liquid extraction is improved, but the device complexity increases
Solution Approach 1:
The straw incorporates a movable or adjustable mechanism that allows the user to dynamically control which openings are active during liquid extraction. This dynamic capability enables selective activation of openings at different depths, achieving reliable depth-specific extraction while reducing structural complexity compared to having all openings permanently active.
3Ease of operation
If the lower end of the straw is bent to an angle, then liquid intake direction is controlled, but turbulent flow is still created affecting depth consistency
Solution Approach 1:
The bent straw design is combined with segmented openings positioned at different depths along the bent section. This allows the straw to maintain its directional intake capability while ensuring that liquid enters through openings at specific depth levels, preventing turbulent flow from mixing liquids of different depths.
4Productivity
If a conical intake area is created, then liquid collection is improved, but the ability to extract from a specific depth is lost
Solution Approach 1:
The conical intake area is segmented into multiple discrete openings positioned at specific depth levels along the cone's surface. This segmentation allows liquid to be collected efficiently from the conical area while maintaining the ability to selectively draw from specific depth layers, preventing the mixing of liquids from different depths.
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 straw effectively minimizes the biological activity of the extracted water, reducing the risk of premature aging and maintaining cellular health by consistently drawing from the least active water layers, while preventing bacterial growth and providing a stable intake mechanism.
Implementation Method 1
The straw also allows for the extraction of water in a laminar flow
Implementation Method 2
The height of the lower part of the straw... and the location of the device to hold openings submerged at a certain depth are chosen so as to allow for the lower part of the straw with the openings to be constantly in an optimal position

AI summary
The straw designed for the intake of water based drink from a container. In the lower part of the flexible straw there are holes that are connected to the main tube of the straw. Above the holes and attached to the straw, there is a floating device which allows for the intake of the drink from the container only from fixed depth ranges, preferably from 5-15 mm from the surface of the water. The straw allows for the protection of the organism of the user from negative effects of the drink on the body's cells.
