Annular Drinking Duct Layout for Controlled Spill-Free Sipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking containers are inconvenient for liquid transfer due to the need for large pivoting motions and uncontrolled liquid flow, making precise liquid drawing difficult, especially for children.
Innovation Solution
A drinking device with a conveying duct connected to an annular distribution duct within the closure cap, allowing uniform liquid flow to the drinking opening, enabling controlled liquid transfer regardless of the container's position, and featuring a design that prevents accidental spilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cup-shaped lid with dispensing openings is used, then liquid can be dispensed from the container, but the lid needs to be pivoted over a large angle and liquid flow is uncontrolled
Solution Approach 1:
The liquid transfer path is segmented into multiple controlled sections: the conveying duct with its inlet opening, the annular distribution duct with circumferential flow paths, and the drinking opening. This segmentation allows each section to control liquid flow independently, eliminating the need for large pivoting motions while maintaining precise dispensing control.
Solution Approach 2:
The annular distribution duct acts as an intermediary between the conveying duct and the drinking opening. It receives liquid from the conveying duct and distributes it uniformly around its circumference before delivery, providing an additional control stage that ensures precise and controlled liquid flow without requiring complex pivoting mechanisms.
2Measurement precision
If liquid flows into the cup-shaped lid, then liquid can be dispensed, but the flow is uncontrolled and precise drawing is difficult
Solution Approach 1:
The annular distribution duct provides different flow characteristics at different locations: liquid enters from the conveying duct at one location and is distributed uniformly around the circumferential path before reaching the drinking opening. This local variation in flow control allows precise measurement and regulation of liquid flow while maintaining ease of operation through the uniform distribution mechanism.
3Device complexity
If the conveying duct is connected directly to the drinking opening, then liquid transfer is simple, but flow control and uniform distribution are poor
Solution Approach 1:
The liquid flow is transitioned from a linear path (conveying duct) to a circumferential path (annular distribution duct). This dimensional change allows the liquid to be distributed uniformly around the drinking opening while maintaining a relatively simple duct connection structure. The annular configuration provides multiple flow paths that converge at the drinking opening, ensuring uniform distribution without complex control mechanisms.

Function Achieved in This Case
The device allows for accurate and controlled liquid flow, enhancing user friendliness by allowing liquid to be drawn from various positions without spilling, and maintaining thermal insulation of the liquid.
Implementation Method 1
liquid flows from the receiving chamber into the conveying duct between the wall elements and then into the annular distribution duct
Implementation Method 2
liquid flows through the conveying duct into the annular distribution duct against gravity when suction pressure is applied to the drinking opening
Implementation Method 3
the annular distribution duct, which defines a circumferential cavity for distributing the liquid flowing in, which is connected to the drinking opening
Implementation Method 4
maintaining thermal insulation of the liquid
