On-wing heating container for beverage makers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage makers used on aircraft face challenges with limescale buildup due to varying mineral content in water supplies from different airports, leading to performance issues and costly maintenance processes.
Innovation Solution
A beverage maker design featuring a heating cavity with a removable retaining cap and a system for using a removable water container, where the heating means is external and uses electromagnetic radiation to heat water, reducing limescale deposition and allowing for easy maintenance without removing the unit from the aircraft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water is heated in a reservoir or passageways, then water is heated for beverage preparation, but limescale deposits accumulate and compromise performance
Solution Approach 1:
The heating element is extracted from direct contact with water and placed in a separate heating cavity. The cavity contains the water while the heating element remains external, preventing limescale from depositing on the heating element itself while still achieving water heating through thermal conduction.
2Productivity
If limescale buildup restricts flow area, then heating performance is compromised, but cleaning or replacement of affected parts is difficult or expensive
Solution Approach 1:
The heating system is segmented into a removable water container and a fixed heating cavity. The water container can be easily removed and replaced, allowing maintenance without disassembling the entire heating system or removing the beverage maker from the aircraft.
Solution Approach 2:
The system enables easy self-maintenance through removable water containers that can be quickly exchanged by technicians on the aircraft, eliminating the need for complex disassembly or specialized service centers.
3Reliability
If beverage maker becomes inoperable due to limescale, then it needs to be removed from aircraft for servicing, but this causes long downtime and high costs
Solution Approach 1:
By segmenting the water container from the heating cavity, maintenance can be performed on the container alone while the heating cavity remains on the aircraft, enabling quick replacement and minimizing operational downtime.
Solution Approach 2:
The water container is extracted as a separate serviceable component, allowing it to be removed, cleaned, or replaced independently without affecting the permanent installation of the heating system on the aircraft.
4Power
If heating element is in direct contact with water, then heating is efficient, but limescale deposits on the heating element reducing performance
Solution Approach 1:
The heating element is taken out from direct contact with water and placed in a separate heating cavity. The cavity walls contain the water while the heating element remains external, eliminating limescale deposition on the heating element while maintaining heating efficiency through thermal conduction through the cavity walls.
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 solution enables preventive maintenance on beverage makers without removing them from aircraft, reducing downtime and maintenance costs by allowing technicians to quickly restore the beverage maker to operating condition.
Implementation Method 1
The means for heating water may comprise one or more antenna configured to generate electromagnetic radiation within the heating cavity, said electromagnetic radiation being capable of heating water.
Data Source
AI summary
A beverage maker comprises a heating cavity, a water input configured to be connected to an external water supply and to channel water from the external water supply towards the heating cavity, a water output configured to channel water away from the heating cavity and a means for heating water. The means for heating water is disposed external to the heating cavity and is configured to heat water within the heating cavity. The heating cavity is configured to receive a removable water container so as to form a fluid flowpath from the water input to the removable water container, and from the removable water container to the water output.
