Communication Control Unit Wireless Error Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication errors in electronic apparatuses, such as printers, lead to reduced user convenience as errors can recur even after initial resolution, necessitating a technique to prevent such reoccurrences.
Innovation Solution
An electronic apparatus with a communication control unit that executes error resolution processing and disables power-saving functions affecting wireless communication when errors occur, including reinstating drivers, interrupting and resuming power supply, and rebooting, while preventing transitions to power-saving modes to stabilize communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power saving functions are enabled to reduce energy consumption, then energy efficiency is improved, but wireless communication stability deteriorates and errors occur more frequently
Solution Approach 1:
The system dynamically adjusts the power saving function status based on communication status. When communication errors are detected, the system transitions from a static power-saving state to a dynamic state where power saving functions are disabled, ensuring communication stability while maintaining energy efficiency during normal operation
Solution Approach 2:
The communication control unit monitors wireless communication status and provides feedback to control power saving functions. When communication errors occur, this feedback mechanism triggers the disabling of power saving functions, creating a closed-loop control system that balances energy consumption and communication reliability
2Reliability
If error resolution processing is performed repeatedly to handle recurring errors, then communication reliability is improved, but user convenience deteriorates due to frequent interruptions
Solution Approach 1:
The system performs preliminary action by proactively disabling power saving functions before communication errors can recur. This preventive measure eliminates the need for repeated error resolution processing, maintaining communication stability and user convenience simultaneously
Solution Approach 2:
The system applies preliminary anti-action by disabling power saving functions in advance to prevent communication errors from occurring again. This counter-measure addresses the root cause of recurring errors rather than merely responding to symptoms, thereby improving reliability without impacting user convenience

AI summary
An electronic apparatus includes a wireless communication unit performing wireless communication and a communication controller controlling communication of the wireless communication unit. When an error occurs in the wireless communication, the communication controller executes predetermined processing for resolving the error and disables a predetermined power saving function that affects the wireless communication.
