Solution Overview
Problem
Current coffee makers on aircraft are either unable to produce a sufficient quantity of high-quality coffee or require frequent service interruptions due to limited capacity and the need for immediate espresso serving to prevent bitterness or cooling.
Innovation Solution
A mobile device with a thermally insulated water tank, brewing unit, and docking station that allows for the production of high-quality coffee products on demand, featuring a trolley base, water tank, brewing unit, heating device, and electrical interface for efficient power supply, enabling continuous operation without internal power sources and minimizing service interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If espresso makers are used to produce high quality coffee products, then the quality of coffee is improved, but the quantity of coffee that can be produced is limited to only one or two cups per operating cycle
Solution Approach 1:
The system divides the coffee preparation function into two separate units: an espresso maker for high-quality espresso (one or two cups) and a coffee maker for large-volume coffee brewing. This segmentation allows each unit to specialize in its function, resolving the contradiction between quality and quantity by providing both capabilities within the same mobile device.
2Manufacturing precision
If espresso is produced immediately to prevent bitterness or cooling, then the quality is maintained, but frequent service interruptions are required to walk around the cabin
Solution Approach 1:
The mobile device enables continuous service by producing both espresso and large volumes of coffee on-demand at various locations throughout the cabin. The dual brewing system allows cabin crew to serve high-quality coffee products continuously without returning to the galley, eliminating service interruptions and maintaining coffee quality throughout the flight.
3Productivity
If a coffee maker is used to produce sufficient amount of coffee for large number of passengers, then the quantity is improved, but the quality of brewed coffee is limited
Solution Approach 1:
The system divides the coffee preparation function into two separate units: an espresso maker for high-quality espresso (one or two cups) and a coffee maker for large-volume coffee brewing. This segmentation allows each unit to specialize in its function, resolving the contradiction between quality and quantity by providing both capabilities within the same mobile device.
4Adaptability or versatility
If mobile devices with internal power sources are used, then operational independence is improved, but device complexity and weight increase
Solution Approach 1:
The mobile device is designed to operate in two modes: with an optional internal battery for independent mobile operation, and when connected to the aircraft's electrical power supply system via a docking station for extended operation. This multi-functionality resolves the contradiction by providing operational independence when needed while allowing simplified operation when docked, reducing the need for large internal power sources.
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
Enables the production of high-quality coffee products in large quantities without significant service interruptions, allowing easy handling and operation during extended periods, while reducing the need for frequent recharging and internal power sources.
Implementation Method 1
The water tank is thermally insulated allowing hot water stored within the water tank to be held at its elevated temperature. In particular, the thermal insulation of the water is designed so as to allow hot water having a temperature of approximately 80 to 85°C to be stored within the water tank for at least one operation cycle of the mobile device without cooling to an extent that a substantial reheating of the water is required.
Implementation Method 2
The mobile device further comprises a heating device which is adapted to heat water received within the water tank.
