Solution Overview

Problem

Operators of injection molding machines face difficulties in identifying why certain movements or actions cannot be performed due to unmet prerequisites, leading to complex navigation through menus or alarm messages, which complicates the process and affects product quality.

Innovation Solution

An operating unit that allows the data processing device to retrieve status information about injection molding machine elements, providing immediate information and warnings on the screen when a manual button is actuated, guiding the operator on activatability or non-activatability, with customizable visualization and display options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the injection molding machine has high complexity with multiple subsystems and parameters, then the machine functionality and control capabilities are improved, but the operator difficulty in identifying unmet prerequisites and navigating to relevant information increases

Engineering Contradiction:
Improvemachine functionalityVSAvoidoperator difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The control unit provides immediate feedback to the operator when a manual button is actuated. If prerequisites are not met, the system displays warning messages and navigates to the specific subsystem or parameter that needs attention, creating a closed-loop feedback mechanism that guides the operator through the complex machine state without requiring manual navigation through multiple menus.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control unit acts as an intermediary between the operator and the complex machine subsystems. Instead of requiring the operator to directly navigate through complex menus and understand all machine states, the control unit translates the machine's complex state into simple, actionable warning messages and automatically navigates to relevant information, mediating the interaction between operator and machine.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the operator must navigate through operating programs and alarm messages to check prerequisites, then comprehensive information is available, but the time required to identify the cause of inoperability increases

Engineering Contradiction:
Improveinformation completenessVSAvoidsearch time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically checking all prerequisites before allowing machine operations. When a manual button is actuated, the control unit proactively verifies whether all necessary conditions are met and, if not, immediately displays the specific unmet prerequisite and navigates to the relevant subsystem, eliminating the need for operators to manually search through alarm messages and operating programs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control unit extracts and highlights only the relevant unmet prerequisite from the complex set of machine parameters and subsystems. Instead of presenting all possible alarm messages and requiring manual navigation, the system extracts the specific cause of inoperability and presents it prominently to the operator, reducing information overload and search time.

Inventive Principle:
Principle #2Taking out (Extraction)

3Loss of information

If comprehensive status information is displayed on the screen, then the operator has complete information about machine state, but the screen complexity and information processing burden increase

Engineering Contradiction:
Improvestatus information availabilityVSAvoidscreen complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The control unit applies local quality by displaying comprehensive status information selectively and contextually. When a manual button is actuated, the system displays detailed status information and warning messages only in the specific context of that button's function and the unmet prerequisites, rather than presenting all possible information simultaneously. This localized information display reduces screen complexity while maintaining completeness of relevant information.

Inventive Principle:
Principle #3Local quality

AI summary

The unit (1) has injection molding elements whose items of information are called up by a data processing device (4). An operating signal is sent to an injection molding machine (2), and the associated items of information are represented on a touch-sensitive display screen (3) if status information associated with the injection molding element indicates activatability. The associated items of information and a warning indication indicating non-activatability are represented on the screen if the status information associated with the injection molding element indicates non-activatability.
