Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing wireless communication systems are used for drones, then general wireless communication functionality is provided, but communication stability deteriorates due to 3D flight movement

Engineering Contradiction:

Improvecommunication stabilityVSAvoid3D flight adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts measurement report configurations based on the drone's flight state. The measurement report control unit modifies report timing, frequency, and content according to real-time flight information, enabling the communication system to adapt to changing 3D positions and maintain stability during flight movements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes communication parameters such as measurement report intervals, reference signal configurations, and handover thresholds based on flight information. By adjusting these parameters according to flight state (e.g., hovering, moving, ascending), the system optimizes communication performance for each flight condition while maintaining overall stability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If measurement report process is controlled based on flight information, then communication stability for flying devices is improved, but system complexity increases

Engineering Contradiction:

Improvecommunication stabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The measurement report control unit acts as an intermediary between the flight information acquisition unit and the wireless communication subsystem. It receives flight state information, processes it according to predefined rules, and generates appropriate control signals for measurement report configuration, thereby managing complexity through modular architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system segments the measurement report process into multiple controllable aspects: report triggering conditions, report timing, report content, and report frequency. Each aspect can be independently adjusted based on flight information, allowing fine-grained control without overwhelming system complexity.

Inventive Principle:
