Solution Overview

Problem

Conventional methods for comminuting and mixing products, such as icing sugar, often result in poor quality due to separate machines that degrade freshly created surfaces and are energetically unfavorable, leading to clumping and reduced flowability.

Innovation Solution

A device that integrates a comminution area with a mixing area in a common machine housing, where comminution and mixing occur sequentially with a defined atmosphere, allowing for immediate conditioning and mixing to stabilize the product's flowability and prevent clumping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate machines are used for comminution and mixing, then each process can be performed with dedicated equipment, but the freshly created surfaces are degraded before mixing and equipment complexity increases

Engineering Contradiction:
Improveproduct qualityVSAvoidnumber of machines
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the comminution device and mixing device into a single integrated machine housing with multiple working areas. The comminution area with comminution elements and mixing area with mixing elements are arranged sequentially within the same housing, allowing freshly comminuted product to be immediately mixed without exposure to degrading environmental conditions. This eliminates the need for separate machines and intermediate transfer operations.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If separate machines are used for comminution and mixing, then each process can be optimized independently, but energy efficiency decreases due to larger machine surface area

Engineering Contradiction:
Improveprocess optimizationVSAvoidheat retention
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

By merging comminution and mixing operations into a single machine housing, the total external surface area of the equipment is reduced compared to using two separate machines. This smaller surface area minimizes heat loss to the environment, improving energy efficiency and process heat retention while still allowing independent optimization of each working area's parameters.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If comminution and mixing are performed in sequence in separate machines, then each process can be controlled independently, but processing time increases and product flowability deteriorates

Engineering Contradiction:
Improveprocess controlVSAvoidprocessing time
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The integrated device enables continuous processing where the product flows directly from the comminution area to the mixing area without interruption or intermediate storage. This continuous action eliminates idle time between operations and prevents the deterioration of product flowability that occurs during delays, while still allowing independent control of each process stage through separate drives and parameter settings.

Inventive Principle:
Principle #20Continuity of useful action

4Device complexity

If comminution elements and mixing elements are arranged sequentially in a common housing, then equipment complexity is reduced, but space utilization becomes more challenging

Engineering Contradiction:
Improvenumber of machinesVSAvoidmachine housing volume
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The device utilizes vertical stacking of working areas within the machine housing, with the comminution area positioned above the mixing area. This vertical arrangement in the height dimension allows both processes to be integrated without significantly increasing the horizontal footprint, efficiently utilizing three-dimensional space within the housing.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
