Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stabilization system uses dedicated inputs for guidance setpoint signals, then the guidance function can be implemented, but the interface management becomes complex and requires adaptation based on guidance system functions
Solution Approach 1:
The patent makes the existing manual command inputs universal by enabling them to accept both manual commands and guidance setpoint signals. The conversion device transforms guidance signals into a format compatible with manual command inputs, allowing the stabilization system to process both types of signals through the same interface without requiring separate dedicated inputs for each function.
Solution Approach 2:
The conversion device acts as an intermediary between the guidance system and the stabilization system. It receives guidance setpoint signals and converts them into control signals that mimic manual command formats, thereby mediating the interface compatibility issue and allowing seamless integration without modifying the stabilization system's existing input structure.
2Adaptability or versatility
If new control functions are added to the aircraft, then the system capabilities are enhanced, but the interface between guidance and stabilization systems must be altered
Solution Approach 1:
By making the manual command inputs universal, the system can accommodate new control functions through software configuration in the conversion device without requiring physical interface modifications. The conversion device can be programmed to handle different signal types and formats, enabling flexible addition of new functions while maintaining interface stability.
Solution Approach 2:
The conversion device provides dynamic adaptability by being able to reconfigure its signal conversion logic based on the specific control function being implemented. This dynamic reconfiguration capability allows new control functions to be added through software updates rather than hardware modifications, maintaining ease of manufacture while enhancing system capabilities.
3Adaptability or versatility
If the stabilization system is adapted for different guidance functions, then the guidance system can be customized, but the system complexity increases
Solution Approach 1:
The conversion device serves as a flexible intermediary that absorbs the complexity of adapting to different guidance functions. Rather than modifying the stabilization system for each guidance function, the conversion device is configured to handle the specific signal formats and conversion requirements, isolating the complexity from the core stabilization system and maintaining its simplicity.
