Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If practical flight inspection by pilot is used for safety evaluation, then the evaluation can be performed with existing human resources, but the validation result is overly dependent on subjective perception and experience leading to inconsistency and error probability
Solution Approach 1:
The patent creates a virtual copy of the flight procedure by importing design data into a three-dimensional virtual scene. This virtual model replicates the actual flight path, obstacles, and environmental conditions, allowing objective validation without relying on pilot subjectivity. The virtual scene serves as a digital twin that can be repeatedly analyzed with consistent results.
Solution Approach 2:
The patent introduces an intermediary system consisting of image capturing devices, data recorders, and processing modules that mediate between the actual flight and the validation process. These devices objectively record flight parameters and compare them against the virtual model, eliminating direct human subjectivity from the validation judgment.
2Measurement precision
If sensory judgment of pilot is used for obstacle detection, then no additional equipment is needed, but the probability of error exists and large uncertainty exists in determining obstacles
Solution Approach 1:
The patent replaces the mechanical human sensory system with electronic image capturing devices and automated processing systems. Cameras and sensors objectively detect obstacles and record flight parameters, while software algorithms process this data to identify and validate obstacles, eliminating human sensory limitations and subjectivity.
Solution Approach 2:
The system enables self-validation by automatically comparing recorded flight data against the virtual three-dimensional model. The processing module autonomously identifies discrepancies, validates obstacles, and generates validation results without requiring human interpretation, thereby improving precision and eliminating human error.
3Loss of information
If three-dimensional animation simulation is used for flight reproduction, then basic flight state can be visualized, but lack detailed information of obstacles, artificial building and lighting environment
Solution Approach 1:
The patent performs preliminary action by capturing and recording detailed environmental data (obstacles, buildings, lighting) during actual flight inspections before validation. This recorded data is then integrated into the virtual three-dimensional scene, enriching the simulation with authentic detailed information that enhances the realism and accuracy of the virtual environment.
4Measurement precision
If practical flight inspection is used for flight ability evaluation, then actual flight conditions can be assessed, but no comparison with design scheme and design specification is available
Solution Approach 1:
The patent implements feedback by automatically comparing recorded flight data against the virtual three-dimensional model and design specifications. The processing module provides real-time feedback on whether the actual flight path, altitude, and parameters conform to the designed flight procedure, enabling precise validation and identification of deviations.
