Operation Display Interface Using History-Based Operation Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The user interface screens in human machine interfaces (HMIs) at production sites need to be flexibly modified to accommodate ongoing improvements in manufacturing processes, but existing systems lack the ability to efficiently generate and update operation objects based on historical user interactions.
Innovation Solution
An operation display system that includes a display unit, an input unit, a control unit, an acquisition unit, and a generation unit to extract patterns from historical user operations and events, generating operation objects that can be used to improve user interface screens and enhance operability by incorporating common and frequently occurring user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user interface screens are manually designed and modified to accommodate production improvements, then the interface can be updated, but the process is time-consuming and lacks efficiency
Solution Approach 1:
The system automatically generates operation objects by analyzing historical operation data without requiring manual intervention. The HMI device self-updates its interface by extracting patterns from recorded user operations and automatically creating corresponding operation objects, eliminating the need for manual screen design and modification.
Solution Approach 2:
The system collects feedback from historical operation data and uses it to automatically update the user interface. By analyzing patterns in recorded user operations and events, the system generates new operation objects that reflect actual usage patterns, creating a closed-loop system where interface improvements are driven by real operational feedback.
2Ease of operation
If operation objects are manually created for each user operation, then the interface can be customized, but the complexity of the system increases
Solution Approach 1:
The system extracts essential patterns from historical operation data to generate operation objects. By identifying and extracting common operation sequences and patterns from recorded data, the system automatically creates operation objects without requiring manual configuration, thereby improving operability while avoiding the complexity of manual system configuration.
Solution Approach 2:
The system creates operation objects by copying and adapting patterns from historical operation data. Instead of manually designing each operation object from scratch, the system replicates successful operation patterns from history, automatically generating operation objects that have already been validated by actual user operations.
3Reliability
If the HMI interface is designed in advance for specific manufacturing facilities, then the interface is optimized for initial use, but it cannot adapt to daily improvements at the production site
Solution Approach 1:
The HMI interface transitions from a static, pre-designed state to a dynamic, self-updating state. The system continuously analyzes historical operation data and automatically generates new operation objects to reflect changes in production processes, enabling the interface to adapt dynamically to improvements while maintaining the reliability of its initial design.
Solution Approach 2:
The system performs preliminary analysis of operation patterns from historical data before generating new operation objects. By pre-processing and analyzing historical operation sequences, the system prepares the foundation for automatic generation of optimized operation objects, ensuring that the interface adapts proactively to production improvements rather than reactively.

AI summary
An operation display system that constitutes at least a part of a control system for controlling a control target includes: a display unit; an input unit that receives a user operation; a control unit that controls the display unit to display a selected page among one or more pages prepared in advance; an acquisition unit that acquires history information in which user operations and events are recorded in a time series; and a generation unit that extracts a pattern constituted of a plurality of user operations included in the acquired history information and that generates an operation object corresponding to a user operation included in the extracted pattern.
