Custom Beverage Vending With On-Site Mixing and Reusable Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The convenience beverage vending industry faces significant environmental waste due to low recycling rates of plastic and aluminum containers, and high energy consumption in bottling, transportation, and distribution, particularly for water-based beverages.
Innovation Solution
A vending machine connected to a municipal water source that uses a multi-stage filtration system to mix concentrated beverage ingredients with water, allowing customers to customize their drinks using a wide variety of ingredients and dispense them into their own containers, reducing waste and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If beverages are sold in plastic bottles and aluminum cans, then convenience beverage vending is widely available, but environmental waste increases due to low recycling rates
Solution Approach 1:
The system enables customers to use their own reusable containers instead of single-use bottles and cans. The vending machine dispenses beverages directly into customer-provided containers, eliminating the need to discard packaged containers and reducing waste associated with low recycling rates.
Solution Approach 2:
The beverage content is extracted from its traditional packaged form and dispensed directly into customer containers. The system separates the beverage liquid from the packaging, allowing the liquid to be vendable without the waste-generating container.
2Ease of manufacture
If convenience beverages are predominately water-based, then beverage vending is simple and widespread, but energy consumption increases due to bottling, transportation, and distribution
Solution Approach 1:
The beverage system is segmented into concentrated ingredient components that are mixed with water at the point of dispensing. Instead of transporting finished beverages, the system transports and stores small amounts of concentrated ingredients locally, dramatically reducing transportation energy requirements.
Solution Approach 2:
Concentrated beverage ingredients serve as intermediaries between the manufacturing process and the final beverage. These concentrates are mixed with water from the municipal supply at the vending machine, eliminating the need to bottle and transport large volumes of finished water-based beverages.
3Loss of energy
If concentrated beverage ingredients are mixed with water at the vending machine, then water transportation is minimized, but device complexity increases due to multi-stage filtration and mixing systems
Solution Approach 1:
The system uses water from the municipal water supply directly at the vending location, eliminating the need for the machine to store or transport water. The machine only needs to handle small amounts of concentrated ingredients and mix them with the locally available water, significantly reducing overall system complexity.
4Adaptability or versatility
If customers can customize beverages with multiple ingredients, then beverage variety increases, but manufacturing complexity increases due to multiple ingredient storage and dispensing mechanisms
Solution Approach 1:
The vending machine uses a universal dispensing mechanism that can handle multiple different concentrated ingredients through a single system. The same mixing and dispensing apparatus that works for one ingredient can be used for any other ingredient, reducing the need for separate complex mechanisms for each beverage type.
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 solution enables efficient use of resources by minimizing water transportation, allowing for customizable beverages, and promoting recycling by using customers' containers, thereby reducing environmental impact and energy consumption.
Implementation Method 1
The municipal water entering the machine goes through a multi-stage filtration process that is custom tailored to the water quality at a specific location site
Implementation Method 2
This allows the bulk of the beverage contents to be supplied to the machine in a highly concentrated form, and mixed into a custom beverage in the machine
Data Source
AI summary
Methods and apparatus describing a convenience beverage vending machine and its operation are described. An embedded computer interface allows consumers to create their own drinks or choose from a menu of drinks. Drinks are dispensed in a container. The beverages may be made from hot water, cold water or carbonated water that is mixed with various flavors of syrup, sweeteners and nutritional supplements. Identification may be presented and the computer recognizes the consumer and pulls up that consumer's account to determine funds available and previous drink selections and mixtures. The machine may incorporate an automatic cleaning cycle for both the valves and the dispense area.
