Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional telemetry systems use traditional communication channels for vehicle monitoring, then communication reliability is maintained, but communication latency increases and power consumption rises
Solution Approach 1:
The patent applies multi-functionality by enabling overhead control channels to serve dual purposes: their traditional function of controlling mobile radiotelephone operations and an additional function of transmitting telemetry data for vehicle monitoring. This allows the system to use existing infrastructure for multiple purposes, reducing latency by utilizing available control channels without requiring dedicated telemetry communication infrastructure.
2Measurement precision
If conventional telemetry systems continuously monitor vehicle parameters, then monitoring accuracy is maintained, but power consumption increases
Solution Approach 1:
The patent implements periodic action by transmitting telemetry data only at specific intervals or when predetermined conditions are met, rather than continuously monitoring and transmitting all vehicle parameters. This approach maintains adequate monitoring accuracy for security and location tracking purposes while significantly reducing power consumption by keeping the communication system in a low-power state between transmission events.
3Reliability
If conventional telemetry systems use dedicated communication channels for vehicle control, then communication reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing the telemetry system to operate on existing overhead control channels that are already part of the mobile radiotelephone network infrastructure. This eliminates the need for dedicated telemetry communication channels and reduces system complexity while maintaining reliable control communication by utilizing the established control channel protocols and infrastructure.
Data Source
AI summary
A telemetry system coupled to a vehicle can communicate with a remote site using the overhead control channels of a wireless network, such as a cellular mobile radiotelephone network. The telemetry system can monitor or control aspects of the vehicle's operations based on remote user input. The telemetry system can receive a command from a data processing center and, based on the command, perform an action at the vehicle such that a user can remotely interact with the vehicle.
