Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a UAV flies in fixed mode with pre-planned route, then the flight route is determined in advance, but the base station cannot dynamically configure or adjust the flight route for UAVs in connected state
Solution Approach 1:
The patent introduces RRC signaling and MAC CE signaling as intermediary mechanisms between the base station and UAV. These signaling protocols serve as the mediator that enables the base station to configure flight route information for UAVs in connected state without requiring complex direct control systems. The signaling acts as a standardized interface that simplifies the interaction while enabling dynamic route configuration.
Solution Approach 2:
The patent extends the existing RRC and MAC CE signaling frameworks, which are universally used for cellular communication control, to also handle flight route configuration. This multi-functional use of existing signaling mechanisms avoids creating separate complex systems while enabling the base station to perform both communication management and flight route configuration functions.
2Productivity
If the base station configures flight route information through RRC or MAC CE signaling, then real-time flight route configuration is enabled, but the signaling overhead and processing complexity increase
Solution Approach 1:
The patent applies partial action by configuring only the necessary flight route information parameters through RRC or MAC CE signaling rather than transmitting complete flight control data. This selective configuration approach enables real-time route management while minimizing the signaling overhead and processing requirements.
Solution Approach 2:
The patent performs preliminary configuration of flight route information through RRC signaling before the UAV executes the flight path. This advance configuration allows the UAV to prepare its flight plan in advance, reducing the need for continuous real-time signaling adjustments and thereby reducing overall signaling overhead.
3Ease of operation
If the UAV operates in dynamic mode with real-time remote control, then the operator has full control, but continuous controller intervention is required which reduces operational efficiency
Solution Approach 1:
The patent enables the UAV to operate autonomously along configured flight routes without requiring continuous operator intervention. The UAV receives flight route information from the base station and independently executes the flight path, serving itself by following the pre-configured route. This self-service operation significantly reduces the time and effort required for continuous remote control while maintaining operational efficiency.
