Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If electromagnetic waves in high frequency band are used for satellite communication, then communication speed is improved, but communication reliability deteriorates due to atmospheric interference

Engineering Contradiction:
Improvecommunication speedVSAvoidcommunication reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system performs preliminary measurement of communication environment parameters (temperature, humidity, pressure, electromagnetic wave characteristics) before actual communication occurs. Based on these measurements, it predicts the communication speed in advance and sets appropriate communication parameters, thereby preparing the system to handle atmospheric interference before it degrades communication reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously measures actual communication environment parameters during communication and compares them with reference values. Based on this feedback, it dynamically adjusts communication parameters to maintain optimal communication speed while compensating for atmospheric interference effects.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If time slots are reserved in advance for satellite communication, then system stability is improved, but communication efficiency deteriorates due to inability to adapt to real-time environmental changes

Engineering Contradiction:
Improvesystem stabilityVSAvoidcommunication efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The system maintains the stable time slot reservation structure but introduces dynamic adjustment of communication parameters within each time slot. By measuring environment parameters and predicting communication speed in real time, the system adapts communication settings dynamically while preserving the overall scheduled structure, thus balancing stability with efficiency.

Inventive Principle:

Solution Approach 1:

The system segments the correlation analysis into multiple independent components: orbital parameter analysis, environment parameter analysis, and communication speed prediction. Each component processes specific data separately and combines results, reducing overall computational complexity while maintaining prediction accuracy through modular analysis.

Inventive Principle:
Principle #1Segmentation
