Screen Definition Device Table-Based Model Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen definition devices for operating panels require extensive time and expertise to create custom screens, especially user-specific screens, as they lack a straightforward table-based definition method, making it difficult to integrate user-defined screens with standard screens without losing shared operational functionality.
Innovation Solution
A screen definition device that combines model screen data with a screen definition table to generate screen data efficiently, allowing for easy creation and integration of both standard and user screens in a table format, using a screen data generating unit and screen data combining unit to handle link information and parameter settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If drawing software is used to define user screens, then screen definition flexibility is improved, but time required for mastering operations and definition complexity increases
Solution Approach 1:
The patent applies the copying principle by creating template screens (model screens) that can be replicated and reused. Instead of defining each screen from scratch using complex drawing software, users can copy existing model screens and modify them to create new screens, significantly reducing the time and expertise required while maintaining flexibility.
Solution Approach 2:
The patent segments screen definition into two independent parts: model screen data (containing section configuration and layout) and screen definition table data (containing element parameters). This segmentation allows users to work with standardized templates while easily customizing specific elements, reducing the complexity of mastering full screen definition operations.
2Adaptability or versatility
If separate model screens and definition tables are prepared for standard and user screens, then screen-specific customization is improved, but information sharing between screens and operational commonality is lost
Solution Approach 1:
The patent implements universality by creating a common model screen that can serve multiple purposes - it can be used as-is for standard screens or as a base template for user-specific screens. The model screen data and definition table structure are designed to be reusable across different screen types, enabling information sharing while maintaining customization capability.
Solution Approach 2:
The patent merges the previously separate model screen data and screen definition table into an integrated screen data structure. This combination allows the system to manage both standard and user screens through a unified data framework, enabling automatic information sharing and consistent operational handling across all screen types while preserving screen-specific customization.
3Ease of operation
If table form definition is used for standard screens, then ease of definition is improved, but capability to define user screens with different section configurations is lost
Solution Approach 1:
The patent applies dynamics by making the model screen data configurable and adaptable. Instead of using a fixed rigid table structure, the model screen can be modified to accommodate different section configurations for user screens. The system dynamically adjusts the model screen data based on user requirements while maintaining the ease of table-form definition through structured data entry.
Data Source
AI summary
A screen definition device includes a screen data generating unit that outputs screen data generated by combining model screen data in which section information is set, with screen definition tables for the model screen data; a screen data combining unit that combines the screen data with the other screen data based on a reference relation indicated by link information of the screen data and the link information of the other screen data; and a screen definition table setting unit that sets screen definition tables in a table form.
