Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a tomography scanner with electrodes is used to determine curd proportion, then measurement capability is achieved, but device complexity and cost increase significantly

Engineering Contradiction:
Improvecurd proportion measurementVSAvoidmeasurement device complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts the measurement function from a complex tomography scanner and implements it using a simple flow meter integrated into the existing whey extraction system. The flow meter measures whey flow rate, and curd proportion is calculated by subtracting this from the total mass flow, thereby achieving measurement capability without the complexity of tomography equipment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses whey flow rate as an intermediary parameter to indirectly determine curd proportion. Instead of directly measuring curd content with complex sensors, the system measures the easier-to-obtain whey flow rate and derives curd information through calculation, simplifying the measurement approach.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If multiple dosing heads are equipped with individual flow meters and actuators, then mass flow control precision is improved, but device complexity increases

Engineering Contradiction:
Improvemass flow control precisionVSAvoiddistribution system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent segments the control system by equipping each dosing head with its own flow meter and actuator, allowing independent control of mass flow to different cheese molds. This segmentation enables precise individual control while maintaining overall system simplicity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic control by using actuators that can adjust the opening degree of each dosing head in real-time based on flow meter measurements. This allows the system to adaptively control mass flow distribution during the cheese pressing process, improving precision without requiring a completely complex fixed system.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a device for determining the mass flow rate of cheese curd granules and whey, particularly in a stream of raw cheese mass flowing from a cheese vat into cheese molds of a cheese press. The device is intended to be simple and reliable. The cheese press comprises at least one open trough (2) and a distribution head (5) with at least one metering head (6) for introducing the raw cheese mass, which is movable along the longitudinal sides of the trough (2). A flow meter (10) is arranged upstream of the metering head (6) on the distribution head (5), which has at least one metering head (6), in the direction of mass flow.
