Coffee Brewing Chamber Shaking for Even Powder Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for feeding coffee powder into coffee machine brewing chambers fail to ensure even distribution and compression of the coffee powder, leading to uneven brewing and suboptimal coffee quality.
Innovation Solution
A device comprising a brewing chamber with a filling opening and a feeding apparatus, coupled with a shaking apparatus that vibrates the brewing chamber to evenly distribute the coffee powder, allowing for subsequent compression by a tamper integrated into the coffee machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If coffee powder is introduced into the brewing chamber container through a filling opening, then the coffee powder is fed into the brewing chamber, but the coffee powder forms an unevenly shaped heap and cannot be compressed by a tamper
Solution Approach 1:
The brewing chamber container is coupled to a shaking apparatus that causes it to vibrate while coffee powder is fed or after feeding is completed. This vibration evenly distributes the coffee powder throughout the brewing chamber container, preventing heap formation and enabling subsequent uniform compression by a tamper.
2Manufacturing precision
If a rotor with rotor blades is used to mix coffee powder evenly, then the coffee powder is distributed uniformly, but a lid must be arranged in the filling opening region preventing tamper insertion
Solution Approach 1:
Instead of using a rotor mechanism that would block tamper insertion, the invention uses a shaking apparatus coupled to the brewing chamber container that vibrates the container to evenly distribute coffee powder, maintaining both uniform distribution and tamper accessibility.
3Quantity of substance
If coffee powder is compressed mechanically by a tamper, then the coffee powder density is increased, but uneven distribution leads to inhomogeneous density distribution
Solution Approach 1:
The shaking apparatus evenly distributes the coffee powder before compression by the tamper. This preliminary action of vibration ensures that when the tamper compresses the coffee powder, the compression is applied uniformly across the entire surface, resulting in homogeneous density distribution throughout the compressed coffee bed.
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 achieves even distribution and compression of coffee powder within the brewing chamber, enhancing the quality of the coffee beverage by ensuring a uniform density and effective brewing volume.
Implementation Method 1
a shaking apparatus (4) which is coupled to the brewing chamber (1) in order to cause it to vibrate
Implementation Method 2
Due to gravity, the coffee powder falls from above through a filling opening into the brewing chamber container

AI summary
In a device for feeding coffee powder into a brewing chamber of a coffee machine, the brewing chamber comprises a brewing chamber container (1) having a filling opening (2) for receiving the coffee powder (a) and a feeding apparatus (3) for feeding the coffee powder into the brewing chamber container through the filling opening (2). By means of a shaking apparatus (4), the coffee powder fed into the brewing chamber is levelled. Thereby, the coffee powder is prevented from piling up in the form of hills during the coffee powder is filled into the brewing chamber.
