A method and system for updating peripheral device settings using a management server, telematics device, and peripheral device communication modules, allowing for sequential transmission and acknowledgement of message segments to apply settings without requiring direct connection changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connection changes are made to update peripheral device settings, then settings can be updated, but operational continuity is disrupted
Solution Approach 1:
The setting update message is divided into multiple sequential message segments that are transmitted independently through the existing connection. Each segment can be processed and applied separately, allowing the peripheral device to maintain operational continuity while receiving setting updates without requiring connection changes.
Solution Approach 2:
A management server acts as an intermediary between the user and the peripheral device, facilitating setting updates through the existing connection via a telematics device. This intermediary enables setting updates without requiring direct connection changes between the user and the peripheral device, maintaining operational continuity.
2Reliability
If sequential message segment transmission is used, then reliable setting updates are achieved, but transmission time increases
Solution Approach 1:
The setting update message is segmented into multiple smaller units that are transmitted sequentially through the existing connection. This segmentation enables reliable transmission by allowing individual segments to be acknowledged and retransmitted if needed, while the overall process remains efficient compared to retransmitting the entire message.
Solution Approach 2:
The system implements acknowledgment mechanisms where the peripheral device confirms receipt of each message segment. This feedback loop ensures reliable setting updates by verifying successful transmission of each segment, while allowing the system to proceed efficiently without waiting for complete message acknowledgment before starting transmission.
3Productivity
If bundled message segments are transmitted, then transmission efficiency is improved, but message complexity increases
Solution Approach 1:
Multiple message segments are bundled together into a single transmission unit that can be sent through the existing connection. This merging improves transmission efficiency by reducing the number of separate transmission operations, while the bundling structure is managed by the management server to minimize complexity at the peripheral device level.
Solution Approach 2:
The bundled message segment structure is designed to be universally compatible with the existing connection protocol, allowing the same bundling mechanism to handle different types of setting updates. This multi-functionality reduces the need for specialized handling logic, thereby reducing overall system complexity despite the bundling.

AI summary
Multiple communication modules are used in updating settings at a peripheral device. A management server communicates settings updates for the peripheral device indirectly via a telematics device installed at a vehicle. Setting update messages are split into message segments. Access point settings for communication with a communication network by the peripheral device can be updated indirectly via the telematics device. Further setting changes received while a setting update is being applied can be saved as pending update session for subsequent communication.
