Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current control systems for unmanned aerial vehicles (UAVs) are cumbersome and difficult to operate, especially when using smartphones, due to lack of sensitivity and precision, requiring extensive practice and attention divided between the control interface and the UAV's flight.
Innovation Solution
A control system comprising a mobile device with application software and an intermediary device equipped with a microprocessor that encodes and transmits control signals to the UAV, allowing for intuitive control orders and automatic hover mode until new instructions are received, reducing overreaction and improving usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If touch panel of smartphone is used to control UAV, then device portability is improved, but control sensitivity and precision deteriorate
Solution Approach 1:
The patent introduces an intermediary device between the smartphone and UAV that translates touch panel inputs into precise control signals. This intermediary contains calibration data and algorithms that compensate for the inherent imprecision of touch panel input, enabling accurate UAV control while maintaining smartphone portability.
2Measurement precision
If orientation sensor, accelerometer, and gyroscope are used for intuitive control, then control sensitivity is improved, but response stability deteriorates due to overreaction
Solution Approach 1:
The patent implements feedback mechanisms that monitor sensor inputs and adjust control responses accordingly. The system uses calibration data to determine appropriate response levels, preventing overreaction to minor sensor fluctuations while maintaining sensitivity to intentional control inputs.
Solution Approach 2:
The system dynamically adjusts control parameters based on calibration data and flight conditions. By changing sensitivity thresholds and response factors, the system maintains optimal balance between responsiveness and stability throughout the flight operation.
3Ease of operation
If smartphone must be moved during control via sensors, then control intuitiveness is improved, but display readability deteriorates
Solution Approach 1:
The patent separates the control function from the display function. The smartphone is used solely for intuitive sensor-based control inputs, while a separate display device shows flight information. This segmentation allows the smartphone to be held steady for display readability while still enabling intuitive control through sensor movements.

AI summary
A control system for an unmanned aerial vehicle is disclosed. The control system includes a mobile device and an intermediary device. The mobile device is equipped with an APP allowing a user to input a control order. The intermediary device has a microprocessor for receiving the control order and generating an execution signal in accordance with the control order, and the execution signal is transmitted to the unmanned aerial vehicle. When the intermediary device does not receive any control order, the microprocessor automatically generates a hover signal for maintaining the unmanned aerial vehicle in a hovering flight state.
