Solution Overview
Problem
Existing beverage preparation machines for coffee and milk preparations are bulky, require user manipulation to switch between coffee and milk zones, and have complex constructions, making them less ergonomic and economical.
Innovation Solution
A compact beverage preparation machine with a fixed coffee dispensing nozzle and an adjustable rotary stirring device, allowing for a single area for coffee, milk, and milk-coffee preparations, featuring a control circuit for single-action preparation and easy cleaning, with a tubular part for conveying hot water/steam and driving the rotary tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate coffee and milk zones are provided in the beverage preparation machine, then the machine can prepare both coffee-based and milk-based preparations, but the machine becomes bulky and complex
Solution Approach 1:
The beverage preparation machine uses a single dispensing zone where the coffee dispensing nozzle and rotary stirring device can serve both coffee-based and milk-based preparation needs. The rotary stirring device can be positioned in different locations (first location for coffee preparations, second location for milk preparations) within the same zone, eliminating the need for separate coffee and milk zones while maintaining versatility.
2Adaptability or versatility
If the coffee dispensing nozzle is movable between coffee position and milk position, then the machine can prepare different types of beverages, but the user must manually maneuver the nozzle increasing operation complexity
Solution Approach 1:
The machine automatically positions the rotary stirring device between the two locations based on the selected preparation type, eliminating the need for manual user manipulation. The control system detects whether a coffee-based or milk-based preparation is desired and autonomously moves the rotary stirring device to the appropriate location.
3Device complexity
If the rotary stirring device is fixed and the container must be tilted for placement, then the device structure is simple, but the operation becomes difficult and less ergonomic
Solution Approach 1:
The rotary stirring device is made movable between two locations within the single dispensing zone. This dynamic positioning capability allows the device to adapt to different preparation types while maintaining a relatively simple overall structure. The mobility is achieved through a controlled mechanism that moves the rotary stirring device between the first location (for coffee preparations) and the second location (for milk preparations).
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 machine achieves a simple, ergonomic, and economical design, allowing for efficient preparation of coffee and milk-based drinks with reduced bulk, easy container handling, and adaptable preparation options, while maintaining a compact form factor.
