Drinking system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing drinking systems, such as the Air Up ® system, experience instability and unpleasant drinking behavior due to significant fluctuations in negative pressure as the bottle is emptied, leading to irregular air and water mixing ratios and the formation of large air bubbles, which affect the taste experience.
Innovation Solution
The introduction of an injector pump arrangement within the drinking straw, comprising a driving nozzle, expansion chamber, and collecting nozzle, along with an optional inlet funnel and mixing chamber, stabilizes pressure conditions and converts laminar flow to turbulent flow, reducing bubble size and improving mixing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple opening in the drinking straw is used for fragrance air intake, then the device structure is simple, but the drinking experience is unpleasant with large air bubbles and unstable mixing
Solution Approach 1:
The simple opening is segmented into a multi-component injector pump arrangement including drive nozzle, expansion chamber, and collecting nozzle. This segmentation allows each component to perform a specific function: the drive nozzle creates negative pressure, the expansion chamber mixes air and liquid, and the collecting nozzle directs the mixture, collectively improving bubble distribution and mixing stability.
Solution Approach 2:
The injector pump arrangement acts as an intermediary device between the fragrance air intake and the drinking straw. It mediates the interaction between air and liquid flows, creating controlled turbulence and proper mixing ratios, thereby transforming the unstable direct intake into a stable, well-mixed flow suitable for drinking.
2Stability of the object's composition
If the opening diameter is reduced to throttle flow, then air-water mixing ratio stabilizes, but drinking resistance increases and用户体验 deteriorates
Solution Approach 1:
Instead of using a fixed small opening, the system employs a dynamic injector pump arrangement where the drive nozzle creates negative pressure that actively draws in fragrance air. The expansion chamber then dynamically mixes this air with the liquid flow, maintaining stable mixing ratios while preserving easy drinking through controlled turbulence and proper pressure differential.
3Quantity of substance
If static negative pressure is used at the intake opening, then fragrance air is drawn in, but the system becomes unstable as the bottle is emptied
Solution Approach 1:
The system uses pneumatic principles through the injector pump arrangement, where the drive nozzle creates negative pressure to draw in fragrance air. The expansion chamber then utilizes hydraulic mixing principles to blend the air-liquid mixture, maintaining stable proportions throughout the drinking process regardless of bottle fill level changes.
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
This configuration results in a more stable and pleasant drinking experience with smaller, well-distributed air bubbles, providing a consistent taste sensation by stabilizing pressure conditions and enhancing the mixing of fragrance-enriched air with liquid.
Implementation Method 1
When a user of the drinking system sucks on the drinking straw, thereby triggering a flow of the beverage contained in the drinking vessel, namely water, a negative pressure is created at the opening in the outer wall of the drinking straw, which draws air in via the fragrance reservoir.
Implementation Method 2
an injector pump arrangement (12) which is connected to the drinking straw (5) or integrated therein and is connected to the suction channel (8) by a main flow path
Implementation Method 3
The introduction of an injector pump arrangement within the drinking straw, comprising a driving nozzle, expansion chamber, and collecting nozzle, along with an optional inlet funnel and mixing chamber, stabilizes pressure conditions and converts laminar flow to turbulent flow, reducing bubble size and improving mixing efficiency.
Implementation Method 4
an injector pump arrangement (12) which is connected to the drinking straw (5) or integrated therein and is connected to the suction channel (8) by a main flow path surrounded by an outer wall or is a component of the suction channel (8)

AI summary
An injector pump arrangement for a drinking system comprises: - a main flow path surrounded by an outer wall; and - an intake opening (17) guided through the outer wall, which can be fluidically connected to an outlet opening (11, 11') of a fragrance reservoir (9, 9').
