Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a voltage converter is used to supply the electromechanical thrust reverser actuator from the distribution network, then the actuator can be powered, but the mass and bulk of the power supply system increases significantly
Solution Approach 1:
The patent merges the power supply functions for the de-icing circuit and the thrust reverser actuator into a single integrated system. The generator mounted on the transmission box directly supplies both the de-icing circuit and the actuator through a rectifier, eliminating the need for separate voltage converters and reducing overall system mass and bulk.
Solution Approach 2:
The invention extracts the actuator power supply function from the main distribution network and voltage converter system. By providing a dedicated power supply path from the generator through a rectifier directly to the actuator, the system removes the bulky voltage converter that would otherwise be required to interface with the distribution network.
2Power
If a voltage converter is used to supply the electromechanical thrust reverser actuator, then the actuator can be powered, but the device complexity increases due to harmonic and current inrush constraints
Solution Approach 1:
The invention extracts the actuator power supply function from the main distribution network and voltage converter system. By providing a dedicated power supply path from the generator through a rectifier directly to the actuator, the system removes the bulky voltage converter that would otherwise be required to interface with the distribution network.
Solution Approach 2:
Instead of converting AC power from the distribution network to DC for the actuator through a complex voltage converter, the system inverts the approach by using a simple rectifier to convert the generator's AC output directly to DC for the actuator. This reversal of the power conversion path eliminates the need for complex voltage regulation and harmonic management.
3Adaptability or versatility
If voltage converters are dimensioned to supply all electrical equipment in the motor area, then all equipment can be powered, but the mass and bulk of the converters increases
Solution Approach 1:
The patent segments the power supply system into dedicated zones: the generator mounted on the transmission box directly supplies the de-icing circuit, while a separate power path through a rectifier supplies the thrust reverser actuator. This segmentation allows each component to be optimally sized for its specific function rather than requiring oversized converters to handle all possible loads.
Solution Approach 2:
The patent merges the power supply functions for the de-icing circuit and the thrust reverser actuator into a single integrated system. The generator mounted on the transmission box directly supplies both the de-icing circuit and the actuator through a rectifier, eliminating the need for separate voltage converters and reducing overall system mass and bulk.
