Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAVs require extensive training and practice for amateur operators to master landing and takeoff, especially on uneven surfaces and in adverse environmental conditions, making these processes challenging and inaccessible to those with little training.
Innovation Solution
The development of methods and apparatus for launching and landing UAVs using sensors to detect positional changes and visual signals, allowing for automatic activation of rotor blades to generate lift and thrust, enabling quick and precise control, including the use of touch, pressure, temperature, and visual sensors to detect hand release or contact for autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional manual control methods are used for UAV launch and landing, then the UAV can be operated with basic equipment, but extensive training and practice are required to master these operations
Solution Approach 1:
The UAV system performs launch and landing operations autonomously by detecting visual signals and automatically controlling rotor blade activation. The system serves itself by using onboard sensors to detect gestures and autonomously execute flight maneuvers without requiring skilled manual control
Solution Approach 2:
The patent replaces manual mechanical control with optical detection systems. Visual sensors capture gestures and positional changes, which are then processed by controllers to automatically actuate rotor blades, substituting the mechanical control link with an optical-detection-and-control system
2Ease of operation
If automated sensor-based control is implemented, then training time is reduced and operation is simplified, but the device complexity increases due to additional sensors and controllers
Solution Approach 1:
The visual sensor system serves multiple functions: detecting launch gestures, tracking positional changes during flight, and identifying landing signals. The controller integrates these various detection functions into a unified automated control system, reducing the need for separate specialized components
3Adaptability or versatility
If manual control is used, then the UAV system remains simple, but operation on uneven surfaces and in adverse environmental conditions becomes challenging
Solution Approach 1:
The system continuously monitors visual signals and positional changes during flight, providing real-time feedback to the controller. This feedback mechanism enables the UAV to automatically adjust its flight path and rotor blade control in response to environmental conditions and surface variations, enhancing adaptability to uneven terrain and adverse conditions
