Image Forming Apparatus Mode-Based Usage Environment Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses struggle to accurately estimate their usage environments, leading to inappropriate security settings due to differing environments such as office, teleworking, and public spaces, and current methods like Japanese Patent Application Laid-Open No. 2019-22099 may yield inconsistent results.
Innovation Solution
An image forming apparatus estimates its usage environment by analyzing communication packets using a learning model, and controls processing to prevent estimation during specific modes to avoid inaccuracies, ensuring accurate security settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If estimation processing is continuously executed using communication packet information, then the usage environment can be estimated, but the estimation result may differ during specific operating states such as manufacturing or maintenance
Solution Approach 1:
The patent applies dynamics by making the estimation processing conditional rather than continuous. The system dynamically adjusts whether estimation processing is executed based on the current operation mode. During specific modes like manufacturing or maintenance, the processing is suspended to prevent inaccurate estimates, while during normal operation it is executed to provide accurate environment estimation. This dynamic control resolves the contradiction between continuous monitoring and estimation accuracy.
Solution Approach 2:
The patent changes the parameter of processing execution state based on operation mode. By monitoring the operation mode parameter and adjusting whether estimation processing is performed accordingly, the system ensures high estimation accuracy during normal operation while avoiding unreliable estimates during special states. This parameter-based control mechanism directly addresses the inconsistency problem.
2Adaptability or versatility
If estimation processing is executed during all operation modes, then comprehensive environment detection is achieved, but unnecessary processing occurs during specific modes causing potential inaccuracies
Solution Approach 1:
The patent extracts and excludes specific operation modes from the estimation processing execution. By identifying and removing manufacturing, maintenance, and other non-normal modes from the processing target set, the system avoids wasting time on unnecessary estimation during these states while maintaining comprehensive detection coverage for all relevant operational environments where estimation is actually useful.
Solution Approach 2:
Instead of executing estimation processing in all possible operation modes (excessive action), the patent applies partial action by selectively executing it only in normal operation modes. This partial execution approach eliminates wasteful processing during special modes while maintaining sufficient coverage for all practically relevant scenarios, optimizing the balance between detection coverage and processing efficiency.

AI summary
An image forming apparatus that communicates with an external apparatus controls estimation processing for estimating a usage environment of the image forming apparatus using information based on communication packets communicated by the image forming apparatus, and issues a notification corresponding to a result of the estimation processing, wherein, in a case where the image forming apparatus is set to a specific mode, control is performed to prevent the estimation processing from being executed.
