Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight tests are conducted to test missile avionics systems, then realistic flight data can be obtained, but the costs and time consumption increase significantly
Solution Approach 1:
The patent applies preliminary action by conducting comprehensive laboratory tests and simulations before actual flight tests. The test system prepares missile avionics systems in advance with pre-configured test scenarios, allowing systematic validation of individual components and subsystems prior to expensive flight testing, thereby reducing the number of flight tests needed while maintaining high test reliability
Solution Approach 2:
The patent uses copying by creating virtual flight scenarios and simulated flight data that replicate real flight conditions. The test system generates synthetic flight data and virtual environmental conditions that mirror actual flight situations, enabling thorough testing without requiring numerous physical flight tests, thus reducing time consumption while maintaining test validity
2Duration of action of moving object
If flight tests are conducted to test GNC functionality for extended periods, then comprehensive GNC testing is achieved, but the cost and resource expenditure increase
Solution Approach 1:
The patent applies segmentation by dividing the test process into distinct modular stages: laboratory-based component testing, simulated flight testing, and actual flight testing. Each stage focuses on specific test objectives and can be independently configured and executed, allowing comprehensive long-duration testing of GNC functionality to be distributed across multiple shorter, less expensive test sessions rather than requiring single extended flight tests
Solution Approach 2:
The patent implements universality through a multi-functional test system that can operate in multiple modes (laboratory mode, simulation mode, and flight test mode) using the same core avionics testbed. This allows the system to perform various types of tests including GNC functionality testing, sensor validation, and algorithm verification across different durations and cost levels, providing comprehensive testing capability without proportionally increasing costs
3Ease of manufacture
If laboratory tests are used to simulate missile flight, then flight test costs are reduced, but realistic flight conditions cannot be fully replicated
Solution Approach 1:
The patent uses an intermediary approach by introducing a hybrid test system that bridges laboratory testing and actual flight testing. The system incorporates flight data recording and playback capabilities, allowing real flight data to be used in laboratory simulations, and enables iterative refinement of test scenarios based on actual flight results, progressively improving test realism while maintaining cost effectiveness
Solution Approach 2:
The patent applies dynamics by creating an adaptive test system that can dynamically adjust test parameters and scenarios based on accumulated flight data and results. The system learns from actual flight tests and automatically refines simulation parameters, environmental conditions, and test scenarios to better match real flight conditions over time, continuously improving test realism without requiring proportionally more expensive flight tests
4Reliability
If multiple flight tests are conducted to account for malfunctions, then comprehensive testing is achieved, but the time and resource consumption increase
Solution Approach 1:
The patent implements feedback by incorporating comprehensive data acquisition and analysis systems that continuously monitor test results and provide immediate feedback on system performance. The test system identifies anomalies, malfunctions, and test failures in real-time and automatically adjusts subsequent test scenarios to address identified issues, eliminating the need for multiple redundant flight tests while ensuring comprehensive validation of missile avionics systems
