Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveease of configurationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveease of parameter adjustmentVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice 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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Engineering Contradiction:
Improveease of configurationVSAvoiddata security
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #23Feedback
