Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If data communication is transmitted over power line networks in electric vehicles, then power delivery and data communication can be integrated, but electrical noise degrades data communication quality

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidelectrical noise interference

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The noise sniffer proactively detects and predicts noise regions before data transmission occurs. The system continuously monitors the power line environment, identifies upcoming noise events, and adjusts communication parameters in advance to avoid interference, rather than reacting after noise degradation occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback by monitoring power line noise characteristics through the noise sniffer, comparing detected noise patterns against predicted noise regions, and dynamically adjusting data transmission timing and frequency based on this feedback loop to maintain communication reliability.

Inventive Principle:

Principle #23Feedback

2Reliability

If noise cancellation and avoidance techniques are implemented, then data communication reliability is enhanced, but device complexity increases

Engineering Contradiction:

Improvedata communication reliabilityVSAvoidnoise detection and cancellation system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The noise sniffer serves multiple functions: it detects current noise levels, predicts future noise regions, provides feedback for transmission scheduling, and enables both noise cancellation and avoidance strategies. This multi-functionality reduces the need for separate dedicated components for each noise mitigation task.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs self-diagnosis and self-adjustment by autonomously monitoring its own communication environment, identifying noise patterns, and modifying its transmission behavior without requiring external intervention or complex external control systems.

Inventive Principle:

Principle #25Self-service
