Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If server-client communication is used for remote monitoring to allow multiple monitors to watch multiple vehicles, then bandwidth utilization is improved, but communication delay increases

Engineering Contradiction:

Improvebandwidth utilizationVSAvoidcommunication delay

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The communication system is segmented into two distinct modes: server-client communication for remote monitoring and peer-to-peer communication for remote driving. This segmentation allows each communication mode to be optimized independently for its specific function, resolving the contradiction between bandwidth efficiency and low latency requirements

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically switches between server-client mode and peer-to-peer mode based on the operational requirements. When remote monitoring is needed, server-client communication is used for efficient bandwidth utilization; when remote driving is needed, peer-to-peer communication is activated for low-latency control signals

Inventive Principle:

Principle #15Dynamics

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The remote driver is designed to perform multiple functions: they can conduct remote driving with full control authority or switch to remote monitoring mode where they can observe multiple vehicles simultaneously. This multi-functionality allows the system to maintain high control precision when needed while reducing personnel costs during normal monitoring operations

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically switches between server-client mode and peer-to-peer mode based on the operational requirements. When remote monitoring is needed, server-client communication is used for efficient bandwidth utilization; when remote driving is needed, peer-to-peer communication is activated for low-latency control signals

AI summary

Remote monitoring and remote driving are selectively provided for a plurality of vehicles including a first vehicle. In remote monitoring for a plurality of vehicles, a server distributes monitoring information received from each of a plurality of vehicles to a plurality of remote cockpits including a remote cockpit. In remote driving for the first vehicle, the server establishes a one-to-one communication between the vehicle and the remote cockpit.
