Programmable Display Automates Mobile Terminal Screen Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for programmable displays in factory automation systems require significant manual effort to create and configure screen data for mobile terminals, placing a heavy work burden on workers, as each mobile terminal often needs individual screen data or programs to display information from connected apparatuses.
Innovation Solution
A programmable display system that is communicatively connected to both control apparatuses and multiple mobile terminals, featuring a storage unit for screen data and a screen creation unit that generates and transmits tailored screen data to each mobile terminal based on device values, reducing the need for manual configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual screen data or programs are created for each mobile terminal, then the screen display functionality is achieved, but the work burden on workers increases considerably
Solution Approach 1:
The patent implements a universal screen data management system where a single master screen data file serves multiple mobile terminals. The screen data is stored in a database with a file management unit that handles distribution to multiple terminals, eliminating the need to create separate screen data for each device while maintaining full functionality.
Solution Approach 2:
The patent merges the screen data creation and management functions into a centralized system. Multiple mobile terminals share a common screen data repository, and the file management unit consolidates the distribution process, reducing redundant work while ensuring each terminal receives appropriate screen data.
2Adaptability or versatility
If manual creation of screen data for mobile terminals is performed, then individual terminal requirements are met, but the process becomes complex and time-consuming
Solution Approach 1:
The system implements self-service through automated screen data distribution. The file management unit automatically retrieves screen data from the database and distributes it to connected mobile terminals without requiring manual intervention for each terminal, simplifying the configuration process while maintaining individual terminal adaptability.
Solution Approach 2:
The patent introduces a file management unit as an intermediary between the database and mobile terminals. This intermediary handles all screen data distribution operations, shielding users from complexity while ensuring proper data delivery to each terminal based on its requirements.
