Custom Beverage Vending With On-Demand 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 from bottling, transportation, and distribution of predominantly 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, with features like automatic cleaning cycles and parental controls.
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 achieved, but environmental waste increases due to low recycling rates
Solution Approach 1:
The patent extracts the beverage contents from traditional containers by using concentrated liquid or powder forms stored in the vending machine. Only water and concentrated ingredients are kept in the machine, while customers bring their own reusable containers, eliminating the need for single-use bottles and cans.
Solution Approach 2:
The patent changes the concentration parameter of beverage ingredients by storing them in highly concentrated liquid or powder forms rather than ready-to-drink diluted forms. This allows for compact storage and on-demand mixing, reducing packaging waste while maintaining beverage quality.
2Ease of operation
If beverages are bottled, transported and distributed in traditional containers, then beverage availability is ensured, but energy consumption increases
Solution Approach 1:
The patent extracts only the essential beverage components (concentrated ingredients and water) from the traditional distribution chain. By storing concentrated forms locally in the vending machine and using municipal water sources, it eliminates the energy-intensive processes of bottling, transporting, and refrigerating full-volume beverages.
Solution Approach 2:
The patent changes the concentration parameter of stored ingredients to highly concentrated forms, which reduces storage volume and weight, thereby minimizing transportation energy requirements while maintaining the ability to produce full-volume beverages on-demand.
3Loss of substance
If concentrated beverage ingredients are mixed with water in the machine, then environmental waste is reduced, but device complexity increases due to filtration and mixing systems
Solution Approach 1:
The patent implements self-service through automated mixing mechanisms where the system automatically combines concentrated ingredients with water according to customer selections. The multi-stage filtration system automatically purifies water, and the machine handles all mixing and dispensing operations without manual intervention, reducing operational complexity despite the sophisticated internal systems.
4Loss of substance
If customers use their own containers for beverage dispensing, then single-use container waste is minimized, but ease of operation decreases due to container management requirements
Solution Approach 1:
The system provides automated containerless dispensing where customers select their desired beverage parameters through an interface, and the machine automatically mixes and dispenses the beverage directly into a container held by the customer. This automation eliminates manual container management steps while maintaining waste reduction benefits.
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
Reduces environmental waste by minimizing single-use containers, optimizes energy use through bulk water supply, and enhances customer experience with customizable beverages and efficient operation.
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
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.
