Custom Beverage Vending With Reusable Containers and On-Site Mixing
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 of predominantly water-based beverages.
Innovation Solution
A vending machine connected to a municipal water source with a multi-stage filtration system that allows customers to customize and dispense beverages into their own reusable containers, using concentrated ingredients and a microprocessor-controlled mixing system for variable ratios of ingredients, enabling the creation of custom beverages and efficient use of resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If beverages are sold in plastic bottles and aluminum cans, then convenience and availability are improved, but environmental waste increases due to low recycling rates
Solution Approach 1:
The invention eliminates disposable containers entirely by using a container-less vending system where beverages are dispensed directly into customer-owned reusable containers. This resolves the contradiction by removing the waste-generating component while maintaining convenience through direct dispensing.
Solution Approach 2:
The vending machine serves multiple functions: it stores concentrated beverage ingredients, mixes custom formulations, and dispenses directly into various customer containers. This multi-functionality allows the system to replace traditional container-based distribution while maintaining ease of access.
2Ease of operation
If beverages are bottled, transported, and distributed in ready-to-drink form, then convenience is improved, but energy consumption increases significantly
Solution Approach 1:
The invention extracts the water component from the beverage distribution process entirely. Instead of transporting bottled water, the system connects to municipal water sources and dispenses only concentrated flavor ingredients mixed with fresh water at the point of use. This eliminates the energy-intensive bottling and transportation of water while maintaining beverage convenience.
Solution Approach 2:
The system changes the concentration parameter of beverage ingredients, storing them in highly concentrated form and diluting them at dispensing. This allows minimal storage space and energy-efficient transportation of ingredient concentrates while producing full-strength beverages on demand.
3Adaptability or versatility
If a wide variety of beverage ingredients are stocked in the machine, then customer customization options are improved, but device complexity increases
Solution Approach 1:
The beverage ingredient system is segmented into separate storage containers, each holding a specific concentrated flavor ingredient. This modular segmentation allows easy addition, removal, and management of individual ingredients while maintaining system versatility. Each segment can be independently managed, reducing overall complexity.
Solution Approach 2:
The system dynamically mixes ingredients based on customer selections rather than pre-configuring fixed combinations. The microprocessor controls variable ratio mixing, allowing the system to adapt to any customer preference from the available ingredient segments. This dynamic approach simplifies ingredient management compared to pre-mixed options.
4Use of energy by moving object
If concentrated beverage ingredients are used instead of ready-to-drink beverages, then energy efficiency is improved, but manufacturing precision requirements increase for mixing ratios
Solution Approach 1:
The system incorporates feedback control through microprocessor monitoring of mixing ratios. The controller tracks the amount of concentrated ingredient dispensed and adjusts flow rates to achieve precise final concentrations. This feedback mechanism ensures consistent beverage quality despite variations in ingredient concentration or dispensing conditions.
Solution Approach 2:
The invention replaces manual or mechanical mixing with microprocessor-controlled electronic regulation of ingredient flow. Electronic control provides more precise and repeatable mixing ratios compared to mechanical systems, ensuring consistent beverage formulation while maintaining energy efficiency through concentrated ingredient use.
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 promoting the use of reusable containers and optimizing energy use through bulk supply and customization of beverages, while providing customers with a wide range of options and enhancing user experience with features like automated cleaning and parental controls.
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
mixed into a custom beverage in the machine, rather than transporting the water to the vending site

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 re-usable 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.
