Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device management systems fail to manage the status of use for each type of input signal, which is necessary for detailed management, especially in educational and consumer settings.
Innovation Solution
A display device management method and system that involves acquiring type information of input signals, transmitting device identification and type information to an information processing device, calculating usage status, and associating this information with organization identification to provide detailed usage statistics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed management of display device usage by input signal type is implemented, then measurement precision of usage status is improved, but device complexity increases due to additional information processing requirements
Solution Approach 1:
The patent introduces an information processing device as an intermediary between the display device and the management system. This intermediary acquires usage information from the display device, stores it in a database, calculates usage status, and generates reports. By placing the complex processing functions in this separate intermediary device, the display device itself remains relatively simple while still achieving detailed usage tracking.
Solution Approach 2:
The display device automatically acquires and transmits its own usage information without requiring manual intervention. The information processing device automatically calculates usage status and generates reports based on the stored data. This self-service approach reduces the need for manual data collection and processing, simplifying the overall system operation despite the detailed tracking requirements.
2Loss of information
If usage information is collected and processed for each device and organization, then information completeness is improved, but loss of time increases due to data collection and processing requirements
Solution Approach 1:
The information processing device continuously acquires and stores usage information in a database as it becomes available, rather than waiting until analysis is needed. This preliminary data collection ensures that when usage status calculation and report generation are required, the data is already prepared and organized, significantly reducing the time needed for analysis while maintaining complete information.
Solution Approach 2:
The system operates continuously to acquire, store, and process usage information. The information processing device maintains an ongoing relationship with the display device, continuously collecting data and updating the database. This continuous operation ensures that usage status can be calculated and reports generated at any time without requiring additional data collection periods, thus reducing time loss while maintaining information completeness.
