Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device information display apparatuses for field devices face challenges such as poor usability and operational inefficiencies due to excessive information display, risk of accessing incorrect data, and lack of general usability and expandability, particularly when maintaining field devices with varying specifications.
Innovation Solution
A device information display apparatus that includes a storage unit for associating position information and reproduction information, a position information acquisition unit for measuring current positions, and a display control unit to calculate distances and reproduce display content based on user instructions, enabling efficient access to required device information by automatically displaying customized screens when the user is near the field device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all device information is displayed using the DD file format, then complete device characteristics are shown, but the display becomes excessively large and operation becomes slow
Solution Approach 1:
The patent extracts and displays only the necessary device information items rather than showing all information defined in the DD file. The system selectively presents relevant parameters based on maintenance needs, removing unnecessary information from the display to improve operation speed while maintaining access to complete device characteristics when needed.
Solution Approach 2:
The device information display is segmented into multiple categories or groups (e.g., operational parameters, diagnostic information, configuration settings). This segmentation allows the system to display only relevant segments based on the current maintenance context, reducing the overall display size and improving operation efficiency while preserving access to complete information.
2Loss of information
If all device information is displayed, then complete device characteristics are shown, but the risk of operational errors increases
Solution Approach 1:
The system extracts and displays only the specific device information items relevant to the current maintenance task or device type. By removing unnecessary information from the display, the system reduces the probability of operators accessing or modifying incorrect parameters, thereby improving operational accuracy while maintaining access to complete device characteristics through structured navigation.
3Adaptability or versatility
If custom templates are coded in text format, then display method flexibility is achieved, but usability deteriorates
Solution Approach 1:
Instead of requiring users to code templates in text format, the system uses pre-defined template patterns that can be selected and applied directly. These templates represent standardized display configurations that replicate common maintenance scenarios, allowing users to achieve flexible display methods through selection rather than coding, thereby improving usability while maintaining adaptability.
4Adaptability or versatility
If proprietary format is used for display menu structure, then user interface modification is enabled, but general usability and expandability are reduced
Solution Approach 1:
The system employs a universal template structure that can accommodate multiple device types and maintenance scenarios through a standardized format. This universal approach enables interface customization across different contexts while maintaining general usability, as the same template framework can be applied universally rather than requiring proprietary formats for each specific case.

AI summary
A device information display apparatus displaying device information acquired by communicating with a field device may include a storage unit that associates and stores first position information indicating a position at which the device information displayed on the display device is acquired and reproduction information for reproducing display content of the display device that has been modified based on an operation instruction for the device information displayed on the display device; a position information acquisition unit that acquires second position information indicating a current position of the device information display apparatus; and a display control unit that calculates a distance between positions indicated by the first position information and the second position information, wherein if the distance is no greater than a prescribed reference distance, the reproduced information corresponding to the first position information is used to reproduce the display content of the display device on the display device.
