Cleaning device for a drinking straw
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cleaning of drinking straws is often laborious and inefficient due to the need for specialized thin brushes or aids, and single-use plastic straws contribute significantly to waste.
Innovation Solution
A cleaning device with a structured design comprising a connection portion, manipulation portion, and outlet portion, featuring a dynamic manipulation portion with a helical element that increases fluid flow speed and introduces rotational motion, enhancing the cleaning effect by creating eddies and swirls, and a sealing mechanism for secure attachment to a tap outlet and the straw.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If single-use plastic straws are used, then convenience and hygiene are improved, but waste and environmental pollution increase
Solution Approach 1:
The patent replaces disposable single-use straws with reusable straws that can be cleaned and used multiple times, eliminating the need for continuous disposal while maintaining convenience. The reusable straw system with integrated cleaning mechanism allows users to clean straws on-the-go, making reusable straws as convenient as disposable ones without the waste accumulation.
2Loss of substance
If reusable drinking straws are used, then waste is reduced, but cleaning becomes laborious and inefficient
Solution Approach 1:
The cleaning device enables users to clean their own straws independently without requiring specialized thin brushes or complex cleaning aids. The device uses a simple water flow mechanism where users attach the straw to the device, activate water flow, and the internal structure automatically cleans the straw interior, making the process self-service and eliminating the need for manual brushing.
Solution Approach 2:
The cleaning device utilizes hydraulic principles by employing water flow under pressure to clean the straw interior. The device includes a water inlet that directs water flow through the straw, using the kinetic energy of the moving water to remove residues and dirt from the straw's inner surface, providing an efficient and simple cleaning mechanism.
3Productivity
If specialized thin brushes are used for cleaning straws, then cleaning effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the cleaning function from complex specialized brushes and reduces it to a simple water flow mechanism. Instead of using mechanical brushes with multiple components, the device uses only water flow under pressure to achieve effective cleaning, thereby simplifying the structure while maintaining or improving cleaning effectiveness.
Solution Approach 2:
The patent replaces the mechanical brush system with a hydraulic system using water flow. Instead of relying on mechanical contact between brush bristles and the straw surface, the device uses the kinetic energy and pressure of water flow to remove dirt and residues, simplifying the mechanical structure while maintaining cleaning effectiveness.
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 device efficiently cleans drinking straws by increasing fluid flow speed and introducing rotational motion, effectively removing dirt while being easy to use and reducing waste through improved cleaning efficiency and adaptability.
Implementation Method 1
the manipulation portion and/or the dynamic means is/are configured such that a flow cross section through the manipulation portion decreases monotonously from the inlet cross section to the outlet cross section... the manipulation portion has a nozzle-like design, so that the flow speed of the fluid increases... The dynamic means have at least one flow manipulator which is shaped and arranged in the manipulation means such that a rotational component of motion can be imposed on the fluid flowing through the cleaning device. The rotational component of motion preferably effects a swirl-like spiral motion of the fluid in the circumferential direction.
Implementation Method 2
the flow dynamics of the fluid are increased by the dynamic means on flowing through the manipulation portion... a fluid flowing through the cleaning device is manipulated particularly efficiently in the manipulation portion, for example by the introduction of eddies, rotations and/or increases in flow speeds.

AI summary
The present invention relates to a cleaning device for drinking straws. The cleaning device can be divided into a connection portion, an outlet portion, and a manipulation portion therebetween. The connection portion is connected fluidically to the outlet portion via the manipulation portion. The connection portion can be configured such that a firm but removable connection of the cleaning device to a water tap can be produced. The outlet portion is designed with receiving structure for receiving a drinking straw. The receiving structure has a sealing surface such that a drinking straw can be tightly received by the outlet portion when in contact with the said sealing surface. The cleaning device can be designed such that a ratio of the inlet cross section to the outlet cross section is more than 10.
