Dynamic Operator Interface for Injection Molding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of injection molding machines face challenges in creating interactive operating sequences due to the need for extensive training to navigate conventional keyboard inputs, leading to time inefficiencies and complexity in the injection molding process.
Innovation Solution
The method enhances the operator interface by presenting dynamic input fields that adapt based on user input, allowing for clearer selection of navigation choices and simplifying the input process through a hierarchical navigation surface with definable lines or columns on the screen, along with the option for favorite fields that enable direct access to parameter images, facilitating easier navigation and parameter editing.

1Ease of operation
If conventional keyboard inputs are used for creating operating sequences, then the machine can execute complex control functions, but the operator requires extensive training and experiences time loss
Solution Approach 1:
The system automatically generates operating sequences by detecting the current machine state and presenting relevant input fields based on the detected configuration. The operator simply confirms automatically generated sequences rather than manually inputting all parameters, allowing the system to serve itself in sequence generation while the operator provides minimal input for confirmation.
Solution Approach 2:
The operator interface dynamically adapts its presentation based on the detected machine configuration and current context. Input fields are selectively displayed or hidden according to the detected state, transforming the static keyboard interface into a dynamic adaptive interface that changes parameters of presentation based on real-time machine conditions.
2Adaptability or versatility
If the operator interface presents all possible input fields, then the operator has complete control options, but the interface becomes complex and difficult to navigate
Solution Approach 1:
The operator interface is segmented into multiple levels: a first level presenting a simplified overview with essential input fields, and a second level providing detailed parameter inputs. The system selectively activates different levels based on the detected machine configuration, presenting only relevant fields at appropriate levels rather than overwhelming the operator with all possible inputs simultaneously.
Solution Approach 2:
The operator interface dynamically reconfigures its structure based on detected machine state. Input fields are added, removed, or activated according to the current configuration, transforming the static complete keyboard into a dynamic subset that adapts its complexity and content in real-time based on machine conditions.
3Manufacturing precision
If the system provides detailed parameter input options, then the operator can precisely control the machine, but the navigation process becomes more complex
Solution Approach 1:
The system performs preliminary detection of the current machine configuration and pre-generates appropriate input fields based on this detection. By preparing and pre-organizing the relevant input fields before the operator needs to input parameters, the system eliminates the need for complex navigation through unused fields, presenting only the necessary precise controls in a logical sequence.
Data Source
AI summary
The invention relates to a method and a device for interactive control of a machine, whereby the operating parameters necessary for the working process of the machine are inputted into a data processing unit (12), for storing the operating parameters, using an input unit (10) with input fields in a form which guides the user. Working processes are thus carried out as a result of the inputs. A data set of the base rules for the working process of the machine is recorded in the data processing unit. A limited selection (11) of possible input choices is provided for the user by application of the data set based on the machine configuration and machine environment, which further comprise compatible parts for addition to the extant parts of a working process. Operator guidance is facilitated, whereby the user is provided with a limited selection (11), corresponding to the further parts of the process, on operating fields, by the input unit (10) on the surface (16) for manual input and/or for input using a manipulator (38).
