Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tele-operated driving sessions are established through conventional communication procedures, then basic communication is possible, but latency is too high and data rates are insufficient for reliable remote vehicle operation

Engineering Contradiction:
Improvereliability of tele-operated drivingVSAvoidlatency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by establishing QoS parameters and session configurations before the actual tele-operated driving session begins. The VAE server pre-configures communication channels with appropriate latency guarantees and data rate allocations, ensuring that when the session starts, the communication infrastructure is already optimized for low-latency, high-reliability operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by dynamically adjusting QoS parameters (such as priority levels, bandwidth allocations, and latency thresholds) based on the specific requirements of the tele-operated driving session. The VAE server modifies communication parameters in real-time to maintain optimal performance for remote vehicle control.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If tele-operated driving sessions are established through conventional communication procedures, then basic communication is possible, but data rates are too low for high-definition video streaming and sensor data transmission

Engineering Contradiction:
Improvereliability of tele-operated drivingVSAvoiddata rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-negotiating and establishing high data rate communication channels before the tele-operated driving session begins. The VAE server configures appropriate bandwidth allocations and prioritizes traffic streams for video and sensor data transmission, ensuring sufficient data rates are available from the start of the session.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by dynamically adjusting data rate parameters and bandwidth allocations based on the specific needs of different data streams (video, sensor data, control commands). The VAE server modifies communication parameters to optimize throughput for high-bandwidth applications while maintaining reliability.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple second devices are involved in the tele-operated driving session, then comprehensive vehicle control is possible, but session management becomes more complex

Engineering Contradiction:
Improvecapability to support multiple remote driversVSAvoidsession management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the intermediary principle by introducing the VAE server as a central mediator that manages sessions with multiple second devices. The VAE server coordinates communication between the first device and multiple second devices, handling session establishment, maintenance, and termination, thereby simplifying the complexity that would otherwise arise from direct peer-to-peer management of multiple remote drivers.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent utilizes universality by designing the VAE server to handle multiple functions simultaneously: managing sessions with multiple second devices, coordinating communication streams, monitoring QoS parameters, and controlling session lifecycle. This multi-functional approach consolidates complexity into a single universal manager rather than requiring separate mechanisms for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)
