Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If parameters are adjusted by repeatedly launching and landing the aircraft, then parameter adjustment capability is achieved, but time consumption increases and operational efficiency deteriorates
Solution Approach 1:
The system performs preliminary actions by establishing a reference flying attitude and measuring reference sensor signals before flight. During flight, parameter adjustment is achieved by comparing current sensor signals with the pre-stored reference signals, eliminating the need for repeated take-offs and landings. The reference data is prepared in advance and used as a baseline for automatic parameter optimization.
Solution Approach 2:
The system enables self-service by allowing the aircraft to automatically adjust its own parameters during flight without pilot intervention or ground-based adjustment. The on-board computer automatically compares sensor signals with reference values and modifies control parameters in real-time, making the aircraft self-tuning and eliminating time-consuming manual adjustment cycles.
2Ease of operation
If manual counter control signals are used to maintain flying attitude, then control capability is achieved, but control accuracy deteriorates due to unidentifiable air movements
Solution Approach 1:
The system implements feedback by continuously monitoring sensor signals during flight and comparing them with pre-stored reference signals. The on-board computer processes the difference between current and reference attitudes to automatically generate correction signals, creating a closed-loop control system that compensates for air movements and maintains accurate flying attitude without pilot intervention.
Solution Approach 2:
The system replaces manual mechanical control with an automated electronic control system. Instead of the pilot manually adjusting control surfaces based on visual observation, the system uses sensor data and on-board processing to automatically adjust control surfaces, substituting human reaction with faster, more precise electronic control that can detect and respond to air movements the pilot cannot perceive.
3Manufacturing precision
If multiple landings are performed for parameter adjustment, then comprehensive parameter optimization is achieved, but operational reliability deteriorates due to increased crash risk
Solution Approach 1:
The system performs preliminary measurement of reference sensor signals during a single flight before parameter adjustment begins. This reference data is stored and used throughout subsequent flights for parameter optimization, eliminating the need for repeated landings and reducing exposure to crash risks while maintaining comprehensive optimization capability through continuous comparison with the reference attitude.
Solution Approach 2:
The system enables continuous parameter adjustment and optimization during flight without interruption or landing. The on-board computer continuously processes sensor signals and adjusts parameters in real-time, maintaining uninterrupted flight operation and eliminating the discontinuous take-off and landing cycles that increase crash risk, thereby ensuring both optimization precision and operational reliability.

AI summary
The invention relates to a method for adjusting parameters in a stabilizing device (4) for stabilizing a flying attitude of a remote-controlled fixed-wing aircraft. To adjust a first parameter for a first axis, a first adjustment signal is transmitted from the transmitter (1) to the stabilizing device (4). The first parameter (P1) is stored during the flight as a result of a first memory signal transmitted from the transmitter (1). A second parameter (P2) for a second axis is then adjusted and stored in a similar manner.
