Communication Apparatus Firmware Update Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses lack the capability to transmit firmware updates to multiple types of electronic devices while ensuring that updates are not inadvertently applied to unintended devices.
Innovation Solution
A communication apparatus with a control unit that obtains firmware information from connected devices, transmits updates as needed, and manages connections differently based on the device type, terminating connections for devices with multiple input devices but maintaining them for devices with a single input key until the update is confirmed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication apparatus transmits firmware to multiple types of electronic devices, then the versatility and applicability of the apparatus is improved, but the risk of updating the wrong device increases
Solution Approach 1:
The patent segments the firmware update process into distinct phases: identification phase (obtaining device information and matching firmware), transmission phase (sending firmware to the device), and confirmation phase (verifying the update). This segmentation allows the system to handle multiple device types systematically while ensuring accurate matching through model name comparison and firmware information verification at each stage.
Solution Approach 2:
The patent implements feedback mechanisms where the communication apparatus obtains firmware information from the electronic device, compares it with the transmitted firmware, and verifies the update result. This feedback loop ensures that the correct device receives the correct firmware update, preventing accidental updates to unintended devices while maintaining the ability to update multiple device types.
2Reliability
If the communication apparatus maintains connection after firmware transmission for all devices, then user confirmation is ensured, but the operation complexity and time consumption increase
Solution Approach 1:
The patent dynamically adjusts the connection maintenance strategy based on device characteristics. For devices with single input keys (where accidental updates are more likely), the connection is maintained until update execution or cancellation is confirmed. For devices with multiple input devices (where user intent is clearer), the connection can be terminated sooner. This dynamic approach ensures user confirmation where needed while reducing unnecessary operational complexity.
3Loss of time
If the communication apparatus terminates connection immediately after firmware transmission, then the operation time is reduced, but the risk of unintended updates increases
Solution Approach 1:
The patent performs preliminary actions before terminating the connection: it obtains firmware information from the device, compares the device model name with the firmware applicable model name, and confirms that the transmitted firmware matches the device requirements. This preliminary verification ensures that the correct device is updated before the connection is terminated, preventing unintended updates while minimizing operation time.
Data Source
AI summary
A communication apparatus that includes a communication interface and provides a function pertaining to firmware update of an electronic device which can be communicated with through the communication interface is disclosed. The apparatus obtains information on firmware currently installed in the electronic device and transmits latest firmware to the electronic device in a case where the installed firmware is not the latest firmware. The apparatus terminates or maintains a connection with the electronic device once the latest firmware finishes being transmitted depending on the number and/or type of input device(s) included in the electronic device.
