Sequential Liquid Dispensing for Taste Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid dispensing technologies fail to effectively enhance taste perception of tastants like sugar and salt, allowing for equivalent taste impressions with lower levels of addition, which is crucial for reducing intake as recommended by health organizations.
Innovation Solution
A liquid dispensing apparatus that contains two liquids with differing tastant concentrations, where the first liquid flows before the second liquid, ensuring the tastant in the first liquid is perceived before the second, allowing for a single continuous sip with enhanced taste perception.

1Quantity of substance
If conventional liquid dispensing technologies are used, then liquids can be dispensed, but taste perception of tastants like sugar and salt cannot be effectively enhanced, requiring higher levels of addition
Solution Approach 1:
The beverage is divided into two separate containers, each containing a liquid with different tastant concentrations. The first container holds a liquid with higher tastant concentration while the second container holds a liquid with lower concentration. This segmentation allows the beverage to be delivered in a controlled sequence where the high-tastant liquid is consumed first, enhancing taste perception, followed by the low-tastant liquid, thereby reducing overall sugar and salt intake while maintaining flavor satisfaction.
Solution Approach 2:
The apparatus is designed to deliver the first liquid with higher tastant concentration before the second liquid. This preliminary action of providing the high-tastant liquid first creates a strong initial flavor impression that enhances the overall taste perception. By establishing this flavor baseline beforehand, the subsequent lower-tastant liquid can be consumed without compromising flavor satisfaction, thus enabling reduced tastant levels while maintaining perceived taste quality.
2Object-affected harmful factors
If two liquids with different tastant concentrations are dispensed simultaneously, then taste enhancement can be achieved, but the flow control becomes complex and difficult to manage
Solution Approach 1:
The dispensing system is segmented into two independent containers, each with its own opening and flow path. This segmentation allows each liquid to be controlled separately through simple gravitational flow mechanisms rather than requiring complex coordinated control systems. The first container with higher tastant concentration and the second container with lower concentration operate independently, simplifying the overall flow control while enabling taste enhancement through sequential delivery.
Solution Approach 2:
Instead of using complex electronic or mechanical flow control mechanisms to manage two liquids, the invention inverts the approach by relying on simple physical principles - gravity and container geometry. The containers are positioned and shaped so that the first liquid naturally flows out before the second liquid when the apparatus is tilted or used. This inversion of control methodology replaces complex control systems with passive physical design, significantly reducing device complexity while maintaining effective flow sequencing for taste enhancement.
3Speed
If the opening of the first container is positioned close to the opening of the second container, then sequential flow is achieved, but the liquids may mix before dispensing
Solution Approach 1:
The apparatus maintains clear spatial segmentation between the two liquid containers with distinct openings positioned close together but separated by physical barriers or structural elements. This segmentation prevents liquid mixing while allowing the openings to be proximity-positioned for sequential flow. The first container's opening and the second container's opening are arranged such that when the apparatus is tilted or used, the first liquid flows out through its opening before the second liquid can mix with it, maintaining composition stability while achieving timely sequential delivery.
Solution Approach 2:
The container geometry and opening positioning are designed so that the first liquid is positioned to flow out first due to gravitational effects and container shape. This preliminary action of the first liquid flowing before the second liquid prevents mixing between the two liquids. The openings are positioned close together to enable rapid sequential flow, but the first liquid's head start in the flow sequence ensures it exits before the second liquid can potentially mix with it, maintaining composition integrity while achieving fast sequential dispensing.
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 apparatus enables a reduction in sucrose and salt intake by providing an enhanced taste experience, allowing users to perceive a beverage as having a consistent flavor while consuming lower amounts, aligning with health recommendations.
Implementation Method 1
when the first and the second liquids are poured from the apparatus, the first liquid flows through the opening in the end of the first container and the second liquid flows through the opening in the end of the second container, such that the first liquid begins to exit the opening in the end of the first container before the second liquid begins to exit the opening in the end of the second container

AI summary
A liquid dispensing apparatus may include a first container containing a first liquid and a second container containing a second liquid. The first and second containers each can have an opening in an end. One of the first liquid and the second liquid can contain a tastant which is essentially absent from the other liquid or is present in a relatively differing amount. When the first and the second liquids are poured from the apparatus, the first liquid flows through the opening in the end of the first container and the second liquid flows through the opening in the end of the second container, such that the first liquid begins to exit the opening in the end of the first container before the second liquid begins to exit the opening in the end of the second container.
