Turkish Coffee Machine Foam Transfer and Overflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Turkish coffee machines fail to completely transfer coffee foam to the beverage receptacle and often result in overflows, while also lacking an efficient automatic mechanism for adjusting coffee and sugar proportions and cleaning the cooking compartment.
Innovation Solution
A Turkish coffee cooking and serving machine with a heated cooking compartment that includes a pushing head moving vertically between cooking and discharge positions, a drive mechanism for controlling the pushing head, and sensors for precise sugar and coffee dosing, ensuring complete foam transfer and automatic cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual or conventional automatic Turkish coffee machine is used, then coffee can be prepared, but the foam cannot be completely transferred to the beverage receptacle and overflows occur
Solution Approach 1:
The cooking compartment is made movable between a cooking position and a discharge position through a drive mechanism. This dynamic positioning allows the compartment to be raised to transfer foam completely to the beverage receptacle and then lowered to prevent overflow, resolving the contradiction between complete foam transfer and overflow prevention
Solution Approach 2:
A control unit controls the drive mechanism based on feedback from the cooking process. The control unit receives signals about the cooking state and automatically adjusts the position of the cooking compartment to ensure complete foam transfer while preventing overflow, achieving reliable foam transfer without manual intervention
2Extent of automation
If conventional Turkish coffee machines are used, then coffee can be cooked, but automatic adjustment of coffee and sugar proportions is not provided
Solution Approach 1:
The machine automatically doses coffee and sugar in precise proportions without manual intervention. The dosing mechanism measures and dispenses the correct amounts of coffee and sugar automatically, allowing the system to serve itself and eliminating the need for complex manual adjustment mechanisms
Solution Approach 2:
Manual adjustment of coffee and sugar proportions is replaced by an automated dosing system. The mechanical dosing mechanism uses sensors and control units to automatically measure and dispense precise proportions, substituting complex manual mechanical adjustment with an automated system that is easier to operate
3Extent of automation
If the cooking compartment is not cleaned automatically, then the structure remains simple, but the cooking compartment becomes contaminated and requires manual cleaning
Solution Approach 1:
The cooking compartment cleans itself automatically through a cleaning mechanism that removes coffee residues and contaminants. The system performs self-maintenance by automatically cleaning the cooking compartment after use, eliminating the need for manual cleaning while keeping the overall structure relatively simple
Solution Approach 2:
The cleaning mechanism operates continuously or periodically to maintain the cooking compartment in a clean state. By continuously removing contaminants during or after the cooking process, the system maintains hygiene without requiring complex disassembly or manual intervention, balancing automation with structural simplicity
