Single-Grip UAV Remote Control for Intuitive Flight and Peripheral Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices for UAVs and other remotely controlled devices are difficult for beginners to use due to the non-intuitive division of yaw, pitch, and roll controls between two joysticks, and require users to manage peripheral devices simultaneously, with complex user-defined response functions based on Newton polynomials that require many nodes and are time-consuming to configure.
Innovation Solution
A remote control device with a single grippable body for controlling yaw, pitch, and roll using force and torque, and a separate input controller for managing peripheral devices, using a Lagrange polynomial function for user-defined response curves with non-evenly spaced nodes, allowing for intuitive control and automatic selection of configuration settings based on device identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two joysticks are used to control yaw, pitch, and roll separately, then control precision is improved, but ease of operation deteriorates for beginners
Solution Approach 1:
The patent combines multiple control functions (yaw, pitch, and roll control) into a single joystick interface. Instead of requiring separate joysticks for each axis, the system integrates all three rotational controls into one unified input device, making it more intuitive and easier to operate while maintaining control precision through software-based axis separation.
Solution Approach 2:
The single joystick is designed to perform multiple control functions simultaneously. By implementing multi-functionality in a single device, the system eliminates the need for multiple specialized joysticks while preserving the ability to precisely control yaw, pitch, and roll through a unified interface that is easier for beginners to master.
2Measurement precision
If both hands are required to operate the remote control device, then control precision is improved, but ease of operation deteriorates when peripheral devices need to be operated simultaneously
Solution Approach 1:
The patent merges the control functions for the remotely controlled device and peripheral devices into a single handheld remote control unit. This integration allows the user to operate both the main device and peripherals with one hand, freeing the other hand for additional tasks while maintaining precise control through the unified interface.
Solution Approach 2:
The remote control device is designed with universal functionality to control both the primary remotely controlled device and associated peripheral devices. This multi-functionality is achieved by integrating multiple control channels into a single device, allowing one-handed operation for all controls without sacrificing precision.
3Manufacturing precision
If user-defined response functions are based on Newton polynomial with multiple nodes, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent changes the mathematical basis for response functions from Newton polynomials to Lagrange polynomials. This parameter change in the underlying mathematical model maintains the ability to define precise response curves while reducing the number of nodes required, thereby simplifying the device complexity and making configuration more manageable.
Solution Approach 2:
The patent modifies the node spacing requirement from even spacing to non-uniform spacing in the Lagrange polynomial implementation. This parameter change allows nodes to be positioned optimally for the desired response characteristics rather than being constrained to uniform intervals, achieving precision with fewer nodes and reduced complexity.
4Manufacturing precision
If multiple nodes are required to define response curves, then manufacturing precision is improved, but loss of time increases during configuration
Solution Approach 1:
The patent changes the polynomial basis from Newton to Lagrange, which fundamentally alters how response curves are constructed. This parameter change enables the system to achieve the same level of response curve precision with fewer nodes, directly reducing the time required for configuration while maintaining manufacturing precision.
5Adaptability or versatility
If configuration settings must be manually selected from multiple stored settings, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements an automatic selection mechanism that allows the system to self-determine the appropriate configuration settings based on device identifiers. Instead of requiring manual selection from multiple stored configurations, the system automatically matches and applies the correct settings, maintaining adaptability while significantly improving ease of operation.
Solution Approach 2:
The system uses device identifiers as feedback to automatically select the appropriate configuration settings. This feedback mechanism allows the remote control device to identify the connected remotely controlled device and automatically apply the correct configuration, eliminating manual selection while preserving adaptability across different device types.
