Annular Drinking Channel for Controlled Spill-Resistant Liquid Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking containers are cumbersome and lack precise control over liquid transport, making it difficult for users to drink efficiently, especially for children, and often result in unintentional spilling.
Innovation Solution
A drinking device with a delivery system that uses an annular distribution channel connected to the drinking opening, allowing liquid to flow against gravity when suction pressure is applied, enabling precise control and even distribution of liquid regardless of the container's position, and featuring a valve to prevent spilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cup-shaped lid with multiple openings is used for liquid dispensing, then liquid can be dispensed, but the lid must be pivoted through a large angle and liquid flows uncontrolled
Solution Approach 1:
The invention extracts the liquid delivery function from a complex pivoting lid mechanism and relocates it to a simple straw-like delivery device with an integrated annular distribution channel. This allows liquid to be delivered directly without requiring large-angle pivoting, simplifying the operation while maintaining the dispensing function.
Solution Approach 2:
The delivery device segments the liquid flow path into a conveying channel for transport and an annular distribution channel for controlled distribution. This segmentation allows precise control over liquid flow and eliminates the need for uncontrolled flow to a discharge opening.
2Ease of operation
If liquid flows through a cavity between outer vessel and insert, then liquid can be accessed, but targeted removal of liquid becomes difficult
Solution Approach 1:
The invention introduces an intermediary annular distribution channel between the receiving chamber and the drinking opening. This intermediary structure receives liquid from the conveying channel and distributes it in a controlled manner, enabling precise control over liquid removal while maintaining easy access.
3Adaptability or versatility
If the drinking device allows liquid flow against gravity, then it can be used in vertical position, but precise control of liquid transport is needed
Solution Approach 1:
The invention uses suction pressure (pneumatic principle) applied to the drinking opening to draw liquid through the conveying channel and into the annular distribution channel. This pneumatic control mechanism enables liquid to flow against gravity in vertical positions while maintaining precise control through the user's suction action, without requiring complex mechanical control systems.
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 allows for easy, precise, and controlled liquid removal, enhancing user comfort and preventing spills, as it can be used like a conventional straw and maintains thermal insulation.
Implementation Method 1
when suction pressure is applied to the drinking opening, even when the drinking device is in a vertical or non-pivoted position, liquid is drawn out of the receiving chamber against the force of gravity flows through the conveying channel into the annular distribution channel
