Automatic beverage maker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic beverage makers are limited in their ability to efficiently brew both single servings and larger quantities of coffee, as they require different pod systems and can introduce metallic flavors due to metal components, and generate excessive waste and costs with single-use pods.
Innovation Solution
An automatic beverage system with a base unit, control system, pump, and interchangeable cartridges that allow for brewing using either pod cartridges or ground coffee beans, featuring a glass housing to prevent metallic flavors and adjustable water saturation for optimal extraction, including a NTC Thermistor and double safety switch for temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If single-use beverage pods are used for brewing, then convenience and speed of beverage preparation is improved, but cost and waste generation increase significantly
Solution Approach 1:
The beverage preparation system is segmented into reusable base components and disposable beverage containers. The base unit with heating element, pump, and control system is reused, while only the beverage containers are disposed of after use. This segmentation reduces waste compared to disposable pods while maintaining convenience.
Solution Approach 2:
The system recovers and reuses the expensive heating and control components in the base unit across multiple beverage preparations. Only the inexpensive beverage containers are discarded, thereby recovering valuable materials and reducing overall waste generation.
2Adaptability or versatility
If multiple beverage pod systems are maintained for different serving sizes, then versatility is improved, but device complexity and cost increase
Solution Approach 1:
The base unit is designed as a universal platform that can accommodate different types of beverage containers (single-serving pods, multi-serving cartridges, ground coffee containers). A single device performs multiple brewing functions by accepting various container types, eliminating the need for separate machines for different serving sizes.
Solution Approach 2:
The system dynamically adapts its brewing parameters (water volume, temperature, flow rate) based on the type of container inserted. The control system detects the container type and automatically adjusts brewing settings, providing versatility without requiring manual configuration or complex mechanical changes.
3Use of energy by stationary object
If metal housing is used for water heating, then manufacturing cost and heat conduction are improved, but metallic flavor contamination occurs
Solution Approach 1:
A non-metallic intermediate material (such as glass or ceramic coating) is placed between the metal heating element and the water. This intermediary layer allows efficient heat transfer from the metal housing to the water while preventing direct contact between water and metal, thereby eliminating metallic flavor contamination.
Solution Approach 2:
The water contact surface of the heating housing is constructed from composite materials combining metal structural components with non-metallic heat-resistant coatings (glass, ceramic, or plastic). This composite structure maintains the heat conduction advantages of metal while preventing metallic flavor transfer to the beverage.

AI summary
An automatic beverage system for producing a hot flavored beverage. The system includes a base unit having a water reservoir, a control system for heating liquid from the reservoir, a cartridge arm having a water injector and a cartridge holder, a pump and tubing system connecting the water reservoir to the cartridge holder and used to move water, the control system housed within the base unit and coupled to the heating element and pump to control temperature and movement of the liquid from the reservoir to the cartridge holder, and a container base positioned in an area adjacent the base unit and below the cartridge holder. The cartridge holder is adapted to receive interchangeable cartridges depending on the type and size of beverage desired. The interchangeable cartridges include a water cartridge, a pod cartridge, and a grounds cartridge.
