Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated systems for preparing Turkish coffee are complex in construction and operation, and the quality of coffee produced is not comparable to traditional manual preparation methods.
Innovation Solution
A simple, single-dose disposable capsule with a cup-shaped container and a flat circular lid featuring a meshed bottom and notched lid design, which uses pressurized hot water to create a swirling motion and effectively mix very fine coffee powder, replicating the traditional brewing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated systems with complex capsules and machines are used to prepare Turkish coffee, then preparation time is reduced and automation is improved, but device complexity increases and coffee quality deteriorates
Solution Approach 1:
The capsule is divided into functional segments: a cup-shaped container for coffee powder, a flat circular lid with peripheral notches for water injection, and a bottom with through-apertures for filtration. This segmentation allows each part to perform its specific function simply, avoiding overall system complexity while enabling automated preparation.
Solution Approach 2:
The invention uses single-dose disposable capsules that are simple in construction and discarded after one use. This eliminates the need for complex reusable components and cleaning mechanisms, reducing device complexity while maintaining automation. The disposable nature ensures consistent quality without requiring complex control systems.
2Ease of operation
If automated systems with complex internal structures (nozzles, ribs, valves) are used, then coffee mixing and percolation are improved, but device complexity increases
Solution Approach 1:
The capsule applies local quality by creating specific flow conditions at key locations: peripheral notches on the lid create swirling motion at the coffee surface, while through-apertures in the bottom create upward flow for percolation. This localized flow control achieves effective mixing and percolation without requiring complex internal structures throughout the capsule.
Solution Approach 2:
The invention uses hydraulic principles by injecting pressurized water through peripheral notches to create swirling motion and force percolation through the coffee powder. The water flow dynamics naturally create the desired mixing and extraction effects without mechanical agitators or complex internal channels.
3Device complexity
If traditional manual preparation methods are used, then coffee quality is maintained with simple tools, but preparation time increases and labor effort increases
Solution Approach 1:
The coffee powder is pre-dosed and pre-packaged in the capsule with the exact amount needed for one serving. This preliminary action eliminates the need for manual measuring and preparation steps, reducing preparation time while keeping the capsule structure simple like traditional tools.
4Ease of operation
If complex automated capsules with internal nozzles and shaped walls are used, then water injection and coffee swirling are improved, but manufacturing complexity increases
Solution Approach 1:
The capsule is manufactured as separate simple components (cup-shaped container, flat lid, bottom) that are assembled together. Each component has a simple geometry suitable for standard injection molding, avoiding the need for complex single-piece manufacturing while achieving the desired water flow and coffee swirling effects through their arrangement and interaction.
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 capsule allows for the preparation of Turkish coffee that is qualitatively comparable to traditional manual methods, with a constructionally and operationally simple design, requiring minimal time and effort, while maintaining the characteristic coffee powder sediment and froth.
Implementation Method 1
uses pressurized hot water to create a swirling motion and effectively mix very fine coffee powder
Implementation Method 2
the cartridge is provided with valves on the bottom and ribs on internal walls such that the turbulence of the water inside the cartridge is encouraged, in order to involve as much granular material as possible in the percolation operation
