Solution Overview

Problem

Industrial mixing machines face issues when mixing tools and containers of different sizes and materials are used, leading to potential damage and inconsistent mixing results due to the need for frequent tool changes.

Innovation Solution

A detection device on the mixing machine checks the compatibility of the mounted mixing tool with the container by identifying features such as diameter, using sensors and identifiers, and activates a safety device to prevent mismatched tool and container engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If different mixing tools are used for different container sizes and materials, then mixing quality is improved, but device complexity and operation time increase due to frequent tool changes

Engineering Contradiction:

Improvemixing qualityVSAvoidtool change complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The detection device checks container dimensions and material properties before the mixing process begins, identifying the required mixing tool in advance. This preliminary detection allows the system to prepare and switch to the appropriate tool before mixing starts, avoiding mid-process tool changes and ensuring optimal mixing quality from the outset.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors mixing process parameters and compares them against optimal values for different materials and container configurations. This feedback mechanism detects when the current mixing tool is not optimal and triggers an automatic tool change, ensuring mixing quality is maintained without requiring manual intervention or complex operator judgment.

Inventive Principle:

Principle #23Feedback

2Area of stationary object

If mixing tool diameter is increased for larger containers, then mixing coverage is improved, but risk of tool damage increases when mismatched with smaller containers

Engineering Contradiction:

Improvemixing coverage areaVSAvoidtool damage risk

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The detection device measures container dimensions before the mixing tool is engaged, and the system proactively prevents mismatched tool-container pairing by blocking tool engagement or alerting the operator. This preliminary protective action eliminates the risk of tool damage from mismatched configurations before the harmful interaction can occur.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The detection device and control system act as an intermediary between the mixing tool and container, verifying compatibility before allowing engagement. This intermediary layer ensures that only appropriately sized tools are matched with corresponding containers, preventing direct harmful interactions while maintaining efficient mixing operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of time

If mixing tool is not changed for smaller containers, then operation time is reduced, but mixing precision deteriorates and tool damage risk increases

Engineering Contradiction:

Improvetool change timeVSAvoidmixing precision

Core Design Contradiction:

Loss of timeVSManufacturing precision

Solution Approach 1:

The detection device automatically identifies container size and material type, and the system autonomously determines the required mixing tool configuration. This self-service capability eliminates the need for manual tool selection and changeovers, reducing operation time while ensuring the correct tool is used for optimal mixing precision through automatic compatibility verification.

Inventive Principle:

Principle #25Self-service

4Reliability

If detection device is added to verify tool-container compatibility, then tool damage prevention is improved, but device complexity increases

Engineering Contradiction:

Improvetool damage preventionVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The detection device replaces manual visual inspection and operator judgment with automated sensors and electronic verification systems. This substitution of mechanical/manual processes with electronic detection simplifies the overall system by eliminating complex manual procedures while providing reliable, consistent tool-container compatibility verification to prevent tool damage.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An industrial mixing machine is disclosed for mixing material to be mixed in mixing containers that are open on the connection side and differ in at least one feature of their design, wherein one mixing container is attachable in each case to the mixing head of the mixing machine for mixing the material to be mixed contained therein, and wherein at least two mixing tools differing in at least one feature of their design are mountable on a mixing head of the mixing machine. The mixing machine has a detection device which is configured to determine whether the mixing tool currently mounted on the mixing head matches with the mixing container which is to be connected to the mixing head and in which the material to be mixed is located, and a safety device in communication with the detection device, which prevents the mixing tool and the mixing container opening from being brought together when the detection device detects that the mixing tool mounted on the mixing head does not match with the mixing container.
