Automated Firmware Update System for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for upgrading firmware in image forming apparatuses require physical presence and are costly, as they involve manual intervention and high costs due to the need for on-site service personnel, especially when errors occur.
Innovation Solution
A system comprising a monitoring server, a transmission server, and an image forming apparatus that detects errors, identifies the faulty firmware type, and automatically requests and applies firmware updates, including associated firmware versions, through a network-based communication protocol like SOAP over HTTP, enabling remote and efficient firmware replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual firmware upgrading by service personnel is performed, then firmware can be upgraded, but high costs and long time are required
Solution Approach 1:
The image forming apparatus automatically detects firmware errors, identifies the faulty firmware type, requests replacement firmware from the monitoring server, and applies the updated firmware without human intervention. This self-service mechanism eliminates the need for service personnel to physically visit the customer location, thereby resolving the contradiction between upgrade reliability and time loss.
Solution Approach 2:
The monitoring server continuously monitors operation information from the image forming apparatus and automatically triggers firmware replacement when errors are detected. This feedback loop enables timely firmware updates without manual intervention, reducing both the time required and maintaining reliability through automated error response.
2Reliability
If service personnel manually upgrade firmware, then firmware can be upgraded, but high costs are incurred
Solution Approach 1:
The automated firmware replacement system allows the image forming apparatus to perform its own firmware maintenance by communicating with the monitoring server. This eliminates the need for expensive on-site service personnel while ensuring reliable firmware updates, thereby resolving the contradiction between upgrade reliability and manufacturing cost.
Solution Approach 2:
The patent replaces the mechanical system of physical service personnel visits with an automated electronic communication system between the image forming apparatus and the monitoring server. This substitution eliminates travel and manual labor costs while maintaining firmware upgrade reliability through automated monitoring and replacement.
3Reliability
If all modules are stopped for firmware replacement, then firmware can be upgraded, but productivity is significantly reduced
Solution Approach 1:
The firmware replacement process is segmented into distinct phases: error detection, firmware identification, firmware download, and selective module stopping. Only the specific module controlled by the faulty firmware is stopped during replacement, while other modules continue operating. This segmentation resolves the contradiction between ensuring reliable firmware updates and maintaining overall system productivity.
Solution Approach 2:
The patent applies local quality by stopping only the specific module that is controlled by the faulty firmware type, rather than stopping all modules. This localized approach ensures that firmware replacement reliability is maintained for the affected module while minimizing impact on overall system productivity through continued operation of unaffected modules.
4Ease of manufacture
If automated firmware replacement is performed, then costs are reduced, but complexity of firmware version management increases
Solution Approach 1:
The monitoring server performs multiple functions: monitoring operation information, detecting firmware errors, identifying faulty firmware types, managing firmware version combinations, and distributing replacement firmware. This universal platform handles all aspects of firmware management centrally, reducing the complexity burden on individual devices while maintaining cost-effective automated replacement.
Solution Approach 2:
The monitoring server acts as an intermediary between the image forming apparatus and the firmware management system. It centralizes the complex tasks of firmware version matching, compatibility verification, and coordinated replacement of multiple firmware types, thereby reducing the complexity that would otherwise exist in the automated replacement process while maintaining cost efficiency.
Data Source
AI summary
A monitoring server that monitors an image forming apparatus and detects an error if any has occurred thereon, identifies a type of firmware that has caused the error, and issues an instruction for replacing a version of the identified type of firmware. The image forming apparatus issues, to a transmission server, a request for transmitting a replacement version of the identified type of firmware. The transmission server refers to a firmware version list table to determine another type of firmware whose version is to be replaced in association with the replacement version of the identified type of firmware. The transmission server transmits the replacement version of the identified type of firmware and the determined another type of firmware to the image forming apparatus. The image forming apparatus receives each firmware transmitted from the transmission server and applies the received firmware to the image forming apparatus.
