Peripheral Settings Updates via Telematics Message Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peripheral devices require connection changes for setting updates, which is inefficient and disruptive to their operation.
Innovation Solution
A method and system for updating peripheral device settings using existing communication modules between a management server, telematics device, and peripheral device, allowing sequential or bundled transmission of setting update messages without requiring new connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If connection changes are implemented for setting updates, then setting updates can be performed, 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 received and processed without requiring a complete connection re-establishment, thereby maintaining operational continuity while enabling setting updates.
Solution Approach 2:
The existing communication connection acts as an intermediary that carries setting update messages between the management server and peripheral device. This intermediary channel enables setting updates without requiring a new dedicated connection, thus preserving operational continuity while achieving the update capability.
2Ease of manufacture
If new connections are established for setting updates, then setting updates can be performed, but system complexity increases
Solution Approach 1:
The existing communication connection is designed to serve multiple functions: both data transmission and setting updates. By making the connection universal, the system eliminates the need for separate dedicated update connections, thereby reducing connection management complexity while maintaining full setting update capability.
Solution Approach 2:
The communication infrastructure is leveraged for dual purposes - routine data communication and setting updates. This multi-functional use of existing connections avoids the complexity of implementing and managing separate update-specific connection protocols.
3Ease of manufacture
If setting updates are transmitted as complete messages, then updates can be applied, but transmission reliability decreases over unstable connections
Solution Approach 1:
Complete setting update messages are segmented into smaller sequential message segments. This segmentation allows for more reliable transmission over unstable connections, as individual segments can be transmitted, acknowledged, and retransmitted independently without losing the entire update message.
Solution Approach 2:
The system implements feedback mechanisms where acknowledgments are sent for received message segments. This feedback enables the transmitter to verify successful reception and retransmit any lost or corrupted segments, thereby improving transmission reliability while maintaining the ability to apply complete updates.

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.
