Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If communication throughput is increased for non-essential services (multimedia, navigation), then service functionality is improved, but communication reliability for critical control systems deteriorates

Engineering Contradiction:

Improveservice functionalityVSAvoidcommunication reliability for control systems

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments communication services into different priority levels (first priority for control systems, second priority for multimedia/navigation). This segmentation allows critical control communications to be guaranteed while non-essential services can utilize remaining bandwidth, resolving the contradiction between service functionality and control system reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different quality standards to different communication services based on their priority. High-priority control services receive guaranteed bandwidth and stricter quality requirements, while low-priority services can tolerate variable quality. This local differentiation enables non-essential services to function while protecting critical communications.

Inventive Principle:

Principle #3Local quality

2Reliability

If communication volume control is implemented for each service, then communication reliability for high-priority services is improved, but system complexity increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic communication volume control where throughput limits are adjusted in real-time based on predicted future throughput and current service priorities. This dynamic approach automatically manages communication reliability without requiring complex manual configuration, resolving the contradiction between reliability and system complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent uses feedback mechanisms where actual communication throughput is monitored and compared against predicted values. Based on this feedback, the system adjusts communication volume controls for different services, enabling automatic reliability management without increasing operational complexity.

Inventive Principle:

Principle #23Feedback

3Stability of the object's composition

If future throughput prediction is used to control communication volume, then communication stability is improved, but computational load increases

Engineering Contradiction:

Improvecommunication stabilityVSAvoidcomputational load

Core Design Contradiction:

Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The patent performs preliminary throughput prediction based on historical communication data before actual communication occurs. This allows the system to pre-determine appropriate communication volume controls, ensuring stability while avoiding the need for complex real-time calculations during actual data transmission.

Inventive Principle:

Principle #10Preliminary action
