Solution Overview

Problem

Existing cheese production apparatuses expose curd blocks to mechanical forces during transfer, leading to defects such as broken-off bits and pinholes.

Innovation Solution

A dosing plate coupled with operating means to support the curd block during transfer, allowing it to be pulled away horizontally and directly positioned above a cheese mold, eliminating the need for separate sluice and transfer plates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the curd block is transferred using separate sluice plates and transfer plates, then the transfer process can be implemented, but the curd block is exposed to mechanical forces causing defects

Engineering Contradiction:
Improvetransfer processVSAvoidcurd block integrity
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The dosing plate is designed to perform multiple functions: it serves as the base for the curd column during draining, the dosing device for cutting curd blocks, the transfer platform for moving curd blocks to the cheese mold, and the protective surface during transfer. By merging these separate functions into a single integrated component, the patent eliminates the need for separate sluice plates and transfer plates, thereby reducing mechanical exposure and preventing curd block defects.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The dosing plate is designed as a multi-functional element that performs draining support, curd block dosing, and transfer operations. This universal design allows the same component to handle multiple process stages without requiring additional specialized components, thus minimizing the number of times the curd block is exposed to mechanical forces.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If multiple separate components (sluice plates, transfer plates) are used for transfer, then the transfer function is achieved, but the device complexity increases

Engineering Contradiction:
Improvetransfer functionVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent consolidates multiple separate components (draining column base, dosing device, sluice plates, transfer plates) into a single integrated dosing plate structure. This merging reduces the total number of components in the system, simplifying the overall device architecture while maintaining the transfer function through the dosing plate's horizontal movement capability.

Inventive Principle:
Principle #5Merging (Combining)

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

Reduces the risk of curd block damage by minimizing mechanical forces and ensuring a direct, smooth transfer, thereby preventing defects like broken-off bits and pinholes.

Implementation Method 1

supporting means are provided for supporting a curd block during a movement of the sliding sleeve from the first to the second position

Methodology Applied
Scientific EffectMechanical Support: Mechanical Force

Implementation Method 2

sliding sleeve is horizontally reciprocable between a first position just under the draining column and a second position above a set-up point for a cheese mold

Methodology Applied
Scientific EffectHorizontal Reciprocating Motion: Mechanical Force

Implementation Method 3

a dosing device is placed, which comprises a horizontally acting guillotine blade. The guillotine blade closes off the column, but is periodically opened

Methodology Applied
Scientific EffectVertical Guillotine Action: Mechanical Force
