Peripheral Log Segmentation for Reduced Communication Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing log collecting systems struggle to identify the cause of malfunctions in peripheral devices connected to a personal computer, as they primarily collect log items related to specific jobs, limiting analysis of issues during other processes and increasing communication load.
Innovation Solution
A log collecting system that includes a computer apparatus and peripheral devices with separate log memory regions for storing operation records and influence logs, allowing continuous or discontinuous acquisition and merging of logs to create comprehensive log information, reducing communication load while facilitating trouble identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the peripheral device sends all operation logs to the PC continuously, then complete log information is collected, but the communication load increases
Solution Approach 1:
The patent extracts only the necessary log information (second logs indicating operational influence) from the peripheral device and sends it to the PC, rather than transmitting all operation logs. This selective extraction reduces communication load while maintaining the ability to identify trouble causes effectively.
Solution Approach 2:
The patent segments log information into two categories: first logs (all operation records stored locally) and second logs (operational influence records transmitted to PC). This segmentation allows the system to maintain complete local records while transmitting only essential diagnostic information, balancing information completeness with reduced communication overhead.
2Loss of energy
If only job-specific log items are collected, then communication load is reduced, but the ability to identify troubles during other processes is limited
Solution Approach 1:
The patent creates a universal log collection mechanism where the second log information serves multiple purposes: it tracks operational influence across all device functions (not just print jobs), enables trouble identification during any process, and maintains reduced communication load. The second logs act as a universal indicator of operational state changes regardless of the specific function being executed.
3Measurement precision
If detailed operation logs are stored and transmitted, then trouble cause identification is improved, but the device complexity increases
Solution Approach 1:
The patent performs preliminary action by pre-identifying and storing only the critical operational influence information (second logs) that indicate potential trouble conditions. This preliminary selection of diagnostic data simplifies the log management structure while maintaining high trouble identification accuracy, avoiding the complexity of managing and processing all detailed operation logs.

AI summary
A log collecting system includes a computer apparatus and at least one peripheral apparatus connected to the computer apparatus. The peripheral apparatus stores a first log relating to all operation of the at least one peripheral apparatus in a first log memory region, and stores, in a second log memory region, a second log indicative of any influence on the operation of the at least one peripheral apparatus among the first logs. The computer apparatus stores a third log relating to the operation of the computer apparatus concerning the at least one peripheral apparatus, acquires and stores the second logs, acquires the first log stored in the first log memory region, and creates one log information with the acquired first log, the third log stored in the third log memory region, and the second log stored in the fourth log memory region when the first log acquiring section acquires the first log.
