Electronic Device Firmware Update Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in securely managing connection information during firmware updates, as they either risk unauthorized access by retaining connection information upon restart or inconvenience by requiring new connection setups post-restart, lacking a balanced approach to security and convenience.
Innovation Solution
An electronic device with a wireless communication section, an FW update mode switching section, and a connection information management section that executes P2P wireless communication, switches to an FW update mode for firmware updates, and manages connection information by keeping it during updates while changing it upon normal restarts to enhance security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection information is retained upon restart, then convenience is improved, but security deteriorates due to risk of unauthorized access
Solution Approach 1:
The patent applies dynamics by making the connection information management flexible and adaptive based on the device's operational state. The system dynamically retains connection information when in FW update mode to ensure convenience during firmware updates, while dynamically changing connection information when in normal operation mode to prevent unauthorized access. This dynamic adjustment of connection information retention policy resolves the contradiction between convenience and security.
2Object-affected harmful factors
If connection information is changed upon restart, then security is improved, but convenience deteriorates due to requiring new connection setups
Solution Approach 1:
The patent applies local quality by implementing different connection information management strategies for different operational modes. In FW update mode, the system retains connection information locally to maintain convenience. In normal operation mode, the system changes connection information locally to enhance security. This localized, mode-specific approach allows the system to optimize for the appropriate characteristic (convenience or security) based on the current operational context.
3Ease of operation
If connection information is kept during FW update, then convenience is improved, but security deteriorates
Solution Approach 1:
The patent applies preliminary action by proactively switching to FW update mode before the firmware update process begins. This preliminary mode switching enables the system to retain connection information in advance, ensuring that the connection setup remains convenient throughout the update process. The mode switch is prepared beforehand, allowing the system to maintain security in normal mode while providing convenience during the critical FW update operation.

AI summary
An electronic device includes: a wireless communication section that executes P2P wireless communication; an FW update mode switching section that switches a mode of the electronic device to an FW update mode in which a firmware of the electronic device is updated; and a connection information management section that manages connection information required for a connection setup for the P2P wireless communication executed by the wireless communication section. The connection information management section keeps the connection information when a power source of the electronic device is turned on after turned off in a specific situation, and changes the connection information when the power source of the electronic device is turned on after turned off in a situation other than the specific situation, and the specific situation includes an FW update situation in which the mode of the electronic device is the FW update mode.
