Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If parameter sensing mechanisms are positioned close to the point of force application, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by positioning parameter sensing mechanisms (force detectors, torque detectors) specifically at or near the point where force is applied to the throttle. This localized sensing arrangement ensures that measurements are taken at the most relevant location, maximizing measurement precision without requiring complex system-wide sensor networks. The sensing mechanism is strategically placed to directly detect the force applied by the pilot, providing accurate local measurements.
2Ease of operation
If haptic feedback is provided to the pilot, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements feedback by incorporating actuators that provide haptic feedback to the pilot based on sensed throttle parameters and aircraft conditions. The control system processes force detection data and generates appropriate haptic responses through the actuator, creating a closed-loop feedback system. This allows the pilot to receive tactile information about engine response and aircraft state, improving control ease while managing complexity through integrated control logic.
Solution Approach 2:
The active throttle assembly provides self-service by automatically adjusting throttle position and providing haptic feedback without requiring constant manual intervention from the pilot. The system uses sensed parameters to autonomously modulate throttle response, reducing pilot workload while maintaining precise control. The actuator system serves itself by using feedback from the sensing mechanisms to automatically correct or augment pilot inputs.
3Adaptability or versatility
If direct mechanical connection is replaced by electrical connection, then adaptability is improved, but measurement precision deteriorates
Solution Approach 1:
The patent applies mechanics substitution by replacing direct mechanical linkages between the throttle and engine with an electrical control system. The physical connection is substituted with electronic sensors, controllers, and actuators that communicate through electrical signals. This allows greater adaptability and programmability while maintaining measurement precision through careful selection and placement of force sensing mechanisms that directly detect pilot input forces.
