Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RC model control systems have limited bidirectional communication, requiring external devices and cables for configuration and calibration of add-on modules like flight attitude controllers, which is inconvenient and often unnecessary.
Innovation Solution
A wireless RC model control system with a bidirectional digital radio link between a transmitting device and a multifunction device in the RC model, allowing for control commands, parameterization, calibration, and data transmission, including secure data communication to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external control units or adjustment devices are used to configure the flight attitude controller, then the controller can be set and calibrated, but additional cables and external devices are required which increases device complexity and reduces ease of operation
Solution Approach 1:
The patent combines the configuration and control functions into a single integrated RC transmitter device. The transmitting device includes both control command transmission capabilities and parameter configuration capabilities, eliminating the need for separate external adjustment devices and cables. This merging of functions directly resolves the contradiction by reducing device complexity while maintaining ease of configuration.
Solution Approach 2:
The RC transmitter is designed with multi-functionality, serving both as a control device for operating the RC model and as a configuration device for setting parameters of the flight attitude controller. The single device can transmit control commands, configure parameters, and receive status information, making it a universal device that eliminates the need for multiple specialized devices.
2Ease of operation
If additional external control units are connected via cable to the electronics box, then parameter adjustment is possible, but the system requires physical connections that reduce ease of operation and increase device complexity
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless radio frequency communication system. The transmitting device communicates with the RC model and flight attitude controller wirelessly, eliminating the need for physical cable connections between external control units and the electronics box. This substitution directly reduces device complexity and improves ease of operation.
3Ease of operation
If a bidirectional wireless radio link is implemented for data transmission, then configuration and control can be performed from a single device, but secure data communication is required to prevent unauthorized access
Solution Approach 1:
The patent implements a bidirectional communication system where the receiving device not only receives control commands but also transmits status information, sensor data, and acknowledgment signals back to the transmitting device. This feedback mechanism enables secure configuration operations by allowing verification of data integrity and authentication of communication partners, thus maintaining data security while enabling ease of configuration.
