Tow Control Handle for Hands-Free UAV Towing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hand-operated remote controls for unmanned aerial vehicles (UAVs) are limiting as they do not allow users to perform other tasks simultaneously, as they require both hands for operation, restricting their versatility in various applications such as skiing, surfing, or rescue operations.
Innovation Solution
A towing system comprising a tow control handle with sensors and control elements that can be operated with thumbs or adjacent fingers, allowing hands-free control of UAVs, along with a user device for wireless communication and obstacle avoidance, enabling users to control UAVs while engaging in other activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hand-operated remote controls are used for UAVs, then control precision is improved, but ease of operation deteriorates because both hands are required
Solution Approach 1:
The patent replaces the traditional mechanical hand-operated remote control system with a wearable device system that uses sensors (accelerometers, gyroscopes, magnetometers) to detect user movements and gestures. This substitution allows control of UAVs through body motion rather than manual manipulation of control sticks, resolving the contradiction by maintaining control precision through accurate motion sensing while dramatically improving ease of operation by freeing both hands for other activities
Solution Approach 2:
The wearable device creates a digital copy of the user's physical movements and gestures, translating them into control signals for the UAV. The sensors capture the user's intended motions and replicate them as precise control commands, maintaining control accuracy while allowing the user to perform other tasks simultaneously
2Reliability
If traditional remote controls require both hands, then control reliability is improved, but adaptability deteriorates for activities like skiing or surfing
Solution Approach 1:
The control system is segmented into multiple independent sensors (accelerometer, gyroscope, magnetometer) that each detect different aspects of user motion. This segmentation allows the system to capture comprehensive movement data while distributing the control functions across different sensor inputs, maintaining reliability through redundant sensing while adapting to various physical activities through flexible sensor data interpretation
Solution Approach 2:
The wearable device is designed with universal applicability across multiple activities such as skiing, surfing, rescue operations, and general UAV control. The sensor-based gesture recognition system can interpret various body movements regardless of the specific activity, making the control system adaptable to different contexts while maintaining reliable control through consistent sensor data processing

AI summary
A towing system is provided that includes a tow control handle that is attached by a tow line to an unmanned aerial vehicle (“UAV”) for towing a user. The tow control handle may include various control elements (e.g., sensors, buttons, switches, rotatable portions, etc.) which may be actuated by a user to provide control signals that are utilized for controlling various aspects of the flight of the UAV (e.g., direction, speed, etc.) A user device that is worn or otherwise carried by the user enables the user to summon the UAV to the user's location when a towing process is to begin and/or when a user is to re-acquire the tow control handle (e.g., after the user releases the tow control handle during the towing process, etc.)
