Varialbe pour flow device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pouring devices lack user control over flow rate and suffer from uncontrolled, uneven fluid flow due to air displacement issues when tilting, resulting in inconsistent pouring.
Innovation Solution
A cap with a spout and channel featuring multiple passages that allow for varying fluid flow rates based on tilt angle, including a first passage for intermediate tilt and a larger second passage for further tilt, ensuring consistent and controlled flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single passage is used in the cap, then the structure is simple, but the flow rate cannot be varied and remains inconsistent
Solution Approach 1:
The cap is divided into multiple passages (first passage and second passage) that are spatially segmented and activated at different tilt angles. This segmentation allows the device to provide different flow rates for different pouring needs, resolving the contradiction between flow rate adaptability and structural simplicity.
Solution Approach 2:
The cap transitions from a static single-passage structure to a dynamic multi-passage structure where passages are selectively activated based on tilt angle. The system dynamically adjusts which passage is open (first passage at intermediate tilt, second passage at greater tilt) to vary the flow rate, making the structure adaptive rather than fixed.
2Reliability
If air displacement is not managed, then the structure is simple, but the fluid flow becomes uncontrolled and uneven
Solution Approach 1:
An air vent is introduced as an intermediary component that manages air displacement during pouring. This air vent allows air to enter the container as liquid exits, preventing vacuum formation and uncontrolled flow surges. The air vent acts as a mediator between the liquid flow and atmospheric pressure, ensuring consistent and controlled pouring.
3Ease of operation
If a limited flow rate is enforced, then flow control is achieved, but user control over flow rate variation is lost
Solution Approach 1:
The pouring device transitions from static flow control to dynamic flow control where the user can vary the flow rate by adjusting the tilt angle. At intermediate tilt angles, the first passage provides a controlled flow, while at greater tilt angles, the second passage opens to provide a greater flow rate. This dynamic adjustment mechanism gives users control over flow rate variation while maintaining reliability through gravitational control.
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
Enables user-controlled fluid flow rates and consistent pouring by utilizing multiple passages in the cap's channel, reducing air displacement effects and achieving a more controlled and consistent fluid flow.
Implementation Method 1
Tilting the container from an upright position towards the spout to an intermediate degree with the cap assembled to the container facilitates fluid flow into the channel through a first passage

AI summary
A cap for a variable pour flow device is configured to close an opening of a container holding a liquid when assembled with the container. The cap includes a spout in communication with an interior of the container when the cap is assembled with the container. The cap is further configured to provide a first fluid flow in which fluid flows through a first passage and the spout when the container with the cap assembled thereto is tilted from an upright position toward the spout to an intermediate degree. The cap is also configured to provide a second, greater fluid flow in which fluid flows through the first passage, a larger second passage, which is spaced from the first passage, and the spout when the container with the cap assembled thereto is tilted further toward the spout from the intermediate degree.
