Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional manual procedures are used for manufacturing and maintaining rotorcraft, then flexibility in handling custom configurations is maintained, but error rates increase and productivity decreases
Solution Approach 1:
The patent replaces manual mechanical procedures with an automated AR-based system that uses sensors, processors, and display devices to guide manufacturing and maintenance operations. The system automatically detects component locations, retrieves relevant procedures, and presents step-by-step instructions, eliminating manual lookup and reducing human error while maintaining flexibility for custom configurations.
Solution Approach 2:
The system enables self-service by providing automated guidance that allows technicians to independently complete complex tasks without extensive training or supervision. The AR display presents context-aware instructions that adapt to the specific rotorcraft configuration, allowing operators to perform manufacturing and maintenance tasks autonomously with reduced error rates.
2Measurement precision
If customized procedures are developed for each rotorcraft configuration, then accuracy of maintenance instructions is improved, but device complexity and time consumption increase
Solution Approach 1:
The system dynamically adapts procedures based on real-time sensor data and rotorcraft configuration. Rather than requiring static customization for each configuration, the system automatically adjusts the displayed instructions, component locations, and maintenance steps based on the detected state of the specific rotorcraft, providing accurate guidance without manual procedure development.
Solution Approach 2:
The system performs preliminary actions by pre-loading and organizing maintenance procedures for various rotorcraft configurations before they are needed. When a specific configuration is detected, the system has already prepared the relevant instructions and can immediately present them, eliminating the need for real-time procedure customization and reducing complexity.
3Measurement precision
If comprehensive digital representations and meta-sensors are integrated into the AR system, then alignment precision is improved, but system complexity and cost increase
Solution Approach 1:
The patent implements a universal AR system architecture that can handle multiple rotorcraft configurations and sensor types through a common platform. The system uses standardized digital representations and meta-sensor interfaces that work across different configurations, reducing integration complexity while maintaining high alignment precision through configurable parameters and adaptive algorithms.
