Solution Overview
Problem
Existing beverage machines lack improved customer convenience and precise control over fluid pressure, leading to inconsistent beverage dispensing and potential clogging.
Innovation Solution
A beverage machine device with a valve unit featuring a pressure control surface arranged outside the main flow channel, utilizing multiple pressure control surfaces and a spring element to optimize valve control, ensuring uniform pressure and preventing excessive brewing pressure, while allowing for adjustable opening resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressure control surface is arranged within the main flow channel, then the valve element can be controlled by fluid pressure, but the pressure distribution in the main flow channel becomes non-uniform
Solution Approach 1:
The pressure control surface is extracted from the main flow channel and positioned in a separate pressure control channel. This allows the valve element to be controlled by pressure acting on the pressure control surface without disrupting the uniform pressure distribution in the main flow channel, thereby resolving the contradiction between valve controllability and pressure uniformity.
2Ease of operation
If the valve element is controlled by fluid pressure acting on the pressure control surface, then customer convenience is improved, but the device complexity increases
Solution Approach 1:
The pressure control surface serves multiple functions: it acts as a control interface for the valve element, a pressure sensing element, and a flow regulation point. By making the pressure control surface multi-functional, the device achieves improved customer convenience without proportionally increasing complexity, as the same structural element performs multiple roles.
3Stability of the object's composition
If the pressure control surface is positioned outside the main flow channel, then uniform pressure is achieved in the main flow channel, but the control precision over valve element movement may be reduced
Solution Approach 1:
A pressure control channel is introduced as an intermediary between the main flow channel and the pressure control surface. This intermediary channel transmits pressure from the main flow channel to the pressure control surface with minimal loss, ensuring that the valve element receives precise pressure control signals while the main flow channel maintains uniform pressure distribution.

Function Achieved in This Case
This configuration enhances customer convenience by maintaining a consistent fluid pressure, preventing clogging, and optimizing beverage dispensing, ensuring a high level of reliability and flexibility in beverage preparation.
Implementation Method 1
the valve unit has at least one spring element which, in at least one operating state, at least partially counteracts a force generated by a fluid on the pressure control surface
Implementation Method 2
as a function of one fluid pressure acting on the pressure control surface to open and/or close the main flow channel by movement of the valve element

AI summary
The invention is based on a beverage machine device, in particular a coffee machine device, with at least one fluid channel (12; 12b) which has at least one main flow channel (20; 20b) and with at least one valve unit (14) which has at least one valve element (16) with at least a pressure control surface (18) and which is provided to open and/or close the main flow channel (20; 20b) by moving the valve element (16) at least as a function of a fluid pressure acting on the pressure control surface (18). It is proposed that the pressure control surface (18) be arranged outside of the main flow channel (20; 20b).
