Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If radio wave communication is used for remote control, then ease of operation is improved, but reliability deteriorates due to interference from magnetic storms and multipath environments
Solution Approach 1:
The patent replaces radio wave communication (electromagnetic) with optical wireless communication using light beams. The communication device transmits control signals and receives images through optical channels, substituting the traditional radio frequency mechanism with an optical mechanism that is immune to magnetic storm interference and multipath effects.
Solution Approach 2:
The patent introduces light as an intermediary medium for communication between the remote controller and the unmanned aircraft. By using visible or infrared light as the transmission medium instead of radio waves, the system achieves reliable communication in environments where radio waves are disrupted by magnetic storms or multipath interference.
2Reliability
If optical wireless communication is implemented, then reliability is improved, but device complexity increases due to gimbal and imaging units
Solution Approach 1:
The communication device on the unmanned aircraft serves multiple functions: it acts as both a light receiver for communication signals and a light emitter for transmitting data back to the controller. The imaging unit serves dual purposes of capturing environmental images and detecting the position of the remote controller's communication device. This multi-functionality reduces the need for separate dedicated components.
Solution Approach 2:
The patent combines the communication receiver, light emitter, and imaging unit into an integrated communication device. The imaging unit is merged with the optical wireless communication system to detect controller position, and the gimbal system is integrated to coordinate both communication alignment and imaging functions, reducing overall system complexity despite the added capabilities.
3Ease of operation
If optical axes alignment is automated using imaging units, then ease of operation is improved, but loss of information increases due to potential detection errors
Solution Approach 1:
The communication device continuously captures images of the remote controller using its imaging unit and uses this visual feedback to automatically adjust the gimbal orientation. The system processes the captured images in real-time to determine the controller's position and orientation, providing continuous feedback for automatic alignment while implementing error correction mechanisms to maintain communication accuracy.
Solution Approach 2:
The system performs preliminary detection of the remote controller's position and orientation before establishing the optical communication link. By预先 capturing images and calculating the required gimbal orientation in advance, the system can proactively align the optical axes before communication begins, reducing the risk of misalignment during operation.
