Management Device Data Collection for Powered-Off Image Forming Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems for image forming devices face inefficiencies in data collection, particularly when devices without power status notification functions are turned off, leading to prolonged data collection times and increased risk of data loss as the system waits for a timeout interval.
Innovation Solution
A management device with a requesting unit to send response confirmation requests, a receiving unit to receive responses, and an acquisition unit to collect data from image forming devices based on their operational status, allowing for efficient data collection from multiple devices regardless of their power status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the management device waits for a timeout interval to detect powered-off image forming devices, then the device can identify all managed devices, but the data collection time is prolonged
Solution Approach 1:
The management device sends a response confirmation request before attempting data collection. This preliminary action allows the device to identify powered-off devices in advance and exclude them from the data collection process, avoiding unnecessary waiting time while ensuring all managed devices are detected.
2Reliability
If the management device collects data from all image forming devices including powered-off ones, then comprehensive data coverage is achieved, but the data collection interval is prolonged
Solution Approach 1:
The management device performs a response confirmation request as a preliminary step to identify which devices are powered on and available for data collection. This allows the device to filter out powered-off devices before attempting data acquisition, maintaining comprehensive coverage of all managed devices while improving collection efficiency.
Solution Approach 2:
The data collection process is segmented into two stages: first, sending response confirmation requests to identify available devices; second, collecting data only from devices that respond. This segmentation separates the identification function from the data collection function, allowing efficient processing.
3Device complexity
If the management device uses a single data collection process for all devices, then the system is simple, but data loss risk increases when devices are powered off
Solution Approach 1:
The management device sends a response confirmation request as a preliminary check before data collection. This simple additional step identifies powered-off devices and prevents data collection attempts from them, eliminating data loss risk without significantly increasing system complexity.
Data Source
AI summary
A management device transmits a response confirmation request to multiple image forming devices, receives a response from any one of the multiple image forming devices, and acquires data indicating an operational status of an image forming device by requesting the pertinent data from an image forming device that has issued a response.
