Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple input mechanisms are used in existing aircraft control systems, then control functionality is comprehensive, but cognitive workload increases and efficiency decreases
Solution Approach 1:
The patent merges multiple input mechanisms into a single control stick that integrates multiple control functions. The control stick includes a grip portion, trigger portion, and throttle portion that can be manipulated with one hand to provide comprehensive control functionality while reducing the number of separate input devices the pilot must manage.
Solution Approach 2:
The control stick is designed as a universal control device that performs multiple functions through different manipulation methods. The same control stick can provide pitch control, roll control, throttle control, and other flight parameters through various input mechanisms integrated into a single device, allowing one component to replace multiple specialized controls.
2Measurement precision
If multiple feedback systems are implemented, then control precision is improved, but system complexity and mass increase
Solution Approach 1:
The patent combines multiple feedback mechanisms into an integrated control system where force feedback, position feedback, and haptic feedback are merged into the single control stick structure. This integration provides precise control information to the pilot through unified feedback channels rather than separate feedback systems.
Solution Approach 2:
The control stick incorporates force feedback mechanisms that provide tactile information to the pilot about aircraft state and control inputs. This feedback system allows the pilot to sense aircraft parameters and control forces directly through the control stick, improving control precision without requiring complex visual or electronic feedback displays.
3Reliability
If complex human controls are used, then control authority is maintained, but ease of operation decreases
Solution Approach 1:
The control stick incorporates self-centering mechanisms and force feedback systems that automatically guide the control input back to neutral positions and provide tactile cues for proper control application. This self-service functionality reduces the cognitive burden on the pilot by providing automatic guidance and feedback, allowing maintainment of control authority with reduced mental effort.

AI summary
The aircraft control system includes an inceptor with a set of primary inceptor axes and a set of secondary inceptor inputs. The inceptor can optionally include a hand rest, a thumb groove, a set of finger grooves, passive soft stops, and/or any other additional elements. The aircraft control system can optionally include a flight controller, aircraft sensors, effectors, and a haptic feedback mechanism. However, the aircraft control system can additionally or alternatively include any other suitable components.
