Turkish Coffee Capsule with Thin Retaining Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee capsules fail to replicate the traditional Turkish coffee preparation method, lacking the characteristic dark crema and fine coffee particles due to high pressure and filtering effects, which are not suitable for the low pressure drop and interaction time required for Turkish coffee.
Innovation Solution
A capsule design with Y-shaped opening elements and a thin, low-thickness retaining wall that opens under pressure to allow a low-pressure drop and interaction time, enabling the passage of fine coffee particles and creating a beverage resembling traditional Turkish coffee, using a cup-shaped body with specific dimensions and materials for efficient coffee extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high pressure is used in coffee capsules, then beverage preparation is efficient and clean, but the characteristic dark crema and fine coffee particles of Turkish coffee cannot be achieved
Solution Approach 1:
The patent changes the pressure parameter from high (typical coffee capsule) to low (Turkish coffee preparation), and adjusts the interaction time parameter to be relatively long, thereby achieving the characteristic dark crema and fine coffee particles while maintaining efficient preparation through the self-opening mechanism
2Productivity
If filtering effect is applied in high pressure capsules, then beverage extraction is efficient, but coffee particles cannot pass to the coffee cup
Solution Approach 1:
The patent changes the pressure parameter from high to low, which eliminates the strong filtering effect and allows coffee particles to pass through to the cup, creating the characteristic sediment layer while maintaining efficient extraction through the self-opening mechanism and adequate interaction time
3Productivity
If relatively large pressure drop is created in capsule, then beverage preparation is efficient, but interaction time between water and coffee particles is insufficient
Solution Approach 1:
The patent changes the pressure drop parameter from large to relatively small, and simultaneously increases the interaction time parameter, thereby achieving both efficient preparation through self-opening and adequate extraction time for characteristic Turkish coffee taste
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 effectively prepares a Turkish coffee beverage with a dark crema and fine particles, matching the traditional preparation process while ensuring a clean and convenient preparation method compatible with existing beverage machines.
Implementation Method 1
the retaining wall is a thin film having a thickness of between 15 and 25 microns... opening means designed to open the retaining wall upon rise in pressure in the capsule
