Turkish Coffee Machine Hydraulic Pushing Head for Quiet Serving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Turkish coffee cooking and servicing machines suffer from noise issues due to gear group friction, increased labor and production costs, and prolonged assembly times due to the complexity of multiple pieces, leading to inefficient production and assembly processes.
Innovation Solution
A Turkish coffee cooking and servicing machine with a heater-cooked cooking chamber and a pushing head that moves vertically between cooking and servicing positions, utilizing a piston plate, drive arm, pump, and control unit to manage water flow silently, eliminating the need for a gear group and reducing production and assembly durations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gear group is used to move the pushing head between cooking and servicing positions, then the pushing head can be moved between positions, but noise occurs due to friction between gear components
Solution Approach 1:
The patent replaces the mechanical gear group with a hydraulic drive system. A hydraulic piston connected to the pushing head moves it between cooking and servicing positions. The hydraulic system uses fluid pressure transmission instead of mechanical gear engagement, eliminating the friction-induced noise while maintaining effective position control of the pushing head.
2Ease of operation
If a gear group with multiple pieces is used, then the pushing head can be moved, but labor force consumption and production costs increase
Solution Approach 1:
The patent integrates multiple separate components into a unified hydraulic drive assembly. The hydraulic piston, connecting rod, and pushing head form an integrated mechanism that replaces the multi-piece gear group. This consolidation reduces the number of parts requiring manufacturing and assembly, thereby lowering production costs and labor requirements.
3Ease of operation
If a gear group made of more than one piece is used, then the pushing head can be moved, but assembly durations and production durations extend
Solution Approach 1:
The patent combines multiple discrete components into a integrated hydraulic drive unit. The hydraulic piston, connecting rod, and pushing head are assembled as a unified mechanism rather than assembling multiple gear components. This integration significantly reduces assembly steps and duration, improving production efficiency.
4Ease of operation
If a gear group is used, then the pushing head can be moved between positions, but the system requires high sensitivity and precision in manufacturing and assembly
Solution Approach 1:
The patent replaces the precision-critical gear assembly with a hydraulic system. The hydraulic piston and connecting rod mechanism is inherently more tolerant of manufacturing variations. Fluid pressure transmission provides smooth, controlled movement without requiring the high precision and sensitivity needed for multi-piece gear engagement, simplifying manufacturing requirements.
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 operates more quietly and reduces production and assembly costs by using a hydraulic drive unit, eliminating the need for a gear group and additional components, resulting in a more efficient and cost-effective Turkish coffee preparation process.
Implementation Method 1
at least one pump which applies water through at least one lower hole and at least one upper hole into said drive chamber and thus which moves the pushing head
Implementation Method 2
a cooking chamber wherein a coffee mixture including Turkish coffee, water and optionally sugar is cooked and having a pushing head defining the base of the cooking chamber whose inner side is heated by means of a heater
