Battery-Powered Notification for Firmware Update Power Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users inadvertently turning off the main power supply switch of image forming apparatuses during firmware updates, leading to incomplete or failed updates, and affecting scheduled print jobs and reserved tasks.
Innovation Solution
Incorporating a battery-powered notification system with a detector and notification controller that alerts users when the main power supply switch is turned off, prompting them to turn it back on before firmware updates or critical tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the update notification screen is displayed only when the user is using the apparatus, then the notification is shown during active use, but the user may inadvertently turn off the main power supply switch without noticing the notification when leaving the office
Solution Approach 1:
The system performs preliminary action by displaying the update notification screen before the user turns off the main power supply switch. The notification is displayed in advance to ensure the user sees it before leaving the office, preventing inadvertent power shutdown during critical update periods. This timing strategy ensures the user is alerted before the action that would prevent firmware update occurs.
2Loss of energy
If the main power supply switch is turned off to save energy or prevent unauthorized use, then power consumption is reduced and security is improved, but firmware updates and scheduled print jobs cannot be executed
Solution Approach 1:
The system implements feedback by detecting when the main power supply switch is turned off and providing immediate notification to the user. The detector monitors the power switch state and the notification mechanism alerts the user when shutdown occurs during critical periods. This feedback loop enables users to understand the consequence of their action and take corrective measures, balancing power saving intentions with operational requirements.
3Device complexity
If the update notification screen is not displayed when the user is not using the apparatus, then the system remains simple and low-power, but the user cannot see the notification when leaving the office
Solution Approach 1:
The notification display system applies dynamics by adjusting its behavior based on the operational state of the apparatus. The system dynamically determines when to display notifications based on whether the main power supply switch is on or off, and whether the apparatus is in a usable state. This dynamic adaptation allows the system to provide notifications in critical states while maintaining simplicity in normal operation, avoiding unnecessary display activity during power-saving modes.

AI summary
An image forming apparatus includes a main power supply switch that turns on and off a main power supply, a battery that is a power source different from the main power supply, a detector that detects switching of the main power supply switch, and a first hardware processor that operates with power supplied from the battery, and provides a notification in response to the detector detecting the switching of the main power supply switch from on to off.
