Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional 2D map-based flight path planning is used, then the operation interface is simple, but the flight path accuracy is poor because it fails to account for the third dimension (height) of obstacles
Solution Approach 1:
The patent transitions from traditional 2D map-based flight path planning to a full 3D environment model that incorporates height information of obstacles such as buildings and structures. This dimensional expansion enables accurate 3D flight path generation that accounts for vertical obstacles, directly resolving the contradiction between flight path accuracy and planning complexity by providing comprehensive spatial awareness.
Solution Approach 2:
The system creates a virtual reality copy of the real-world environment including accurate 3D models of obstacles and terrain. This virtual replica allows operators to plan and verify flight paths in a risk-free digital environment before actual UAV execution, improving accuracy without proportionally increasing operational complexity.
2Ease of operation
If traditional 2D flight path planning is used, then the learning curve is long and operator familiarity takes significant practice, but the interface simplicity is maintained
Solution Approach 1:
The virtual reality environment provides an intuitive visual replica of the real world that operators can interact with naturally. This immersive 3D interface reduces training time by allowing operators to mentally rehearse and plan flights in a realistic setting before actual operation, eliminating the need for extensive practice with abstract 2D interfaces.
Solution Approach 2:
The system enables operators to perform preliminary flight path planning and verification in the virtual environment before actual UAV execution. This advance preparation in an intuitive 3D space reduces the time needed to become proficient, as operators can visualize and adjust paths without the pressure of real-world consequences.
3Reliability
If 3D flight path generation is implemented, then the flight path accuracy improves, but the system complexity increases
Solution Approach 1:
The system generates a detailed virtual reality copy of the environment with accurate 3D obstacle models. This virtual replica serves as a reliable digital twin that enables precise flight path planning and verification, improving reliability by allowing multiple simulations and adjustments without increasing physical system complexity.
Solution Approach 2:
The system performs preliminary flight path generation, validation, and optimization in the virtual environment before actual UAV execution. This advance planning in a controlled digital space improves flight path reliability by identifying and resolving potential issues beforehand, while keeping the actual UAV system relatively simple.
4Ease of operation
If virtual reality device is used for flight path verification, then the intuitive understanding improves, but the equipment requirement increases
Solution Approach 1:
The system creates a comprehensive virtual reality copy of the real-world environment that can be viewed and interacted with through VR headsets. This immersive digital replica provides intuitive first-person perspective verification of flight paths, allowing operators to experience the flight from the UAV's viewpoint and make accurate adjustments.
Solution Approach 2:
The virtual reality environment serves as an intermediary between the operator and the physical UAV. This digital mediation layer provides intuitive verification capabilities by rendering the flight path in an immersive 3D space, reducing the need for complex direct control interfaces while improving verification intuitiveness.

AI summary
Methods and associated systems and apparatus for generating a three-dimensional (3D) flight path for a moveable platform such as an unmanned aerial vehicle (UAV) are disclosed herein. The method includes receiving a set of 3D information associated with a virtual reality environment and receiving a plurality of virtual locations in the virtual reality environment. For individual virtual locations, the system receives a corresponding action item. The system then generates a 3D path based on at least one of the set of 3D information, the plurality of virtual locations, and the plurality of action items. The system then generates a set of images associated with the 3D path and then visually presents the same to an operator via a virtual reality device. The system enables the operator to adjust the 3D path via the virtual reality device.
