Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full-motion or partial-motion flight simulator systems are used to provide tactile feedback and improve training realism, then training effectiveness is improved, but device complexity and cost increase significantly
Solution Approach 1:
The system divides the flight training functionality into two separate components: a mobile data acquisition unit that captures flight data during actual flights, and a separate processing system that analyzes the data and generates visual feedback. This segmentation eliminates the need for complex motion platforms while preserving training value through data-driven insights.
Solution Approach 2:
Instead of physically replicating flight sensations through motion platforms, the system creates a digital copy of the flight experience by capturing actual flight data and visualizing it in synthetic environments. This allows trainees to review and analyze real flight data without requiring expensive motion simulation hardware.
2Measurement precision
If inertial measurement units with GPS are permanently mounted in aircraft to capture flight data, then measurement precision is improved, but adaptability and portability deteriorate
Solution Approach 1:
The data acquisition unit is designed as a universal, multi-functional device that can be mounted on various types of aircraft and even attached to human bodies for different training applications. The same core hardware platform supports multiple sensor configurations and data collection modes, making it adaptable to diverse flight training scenarios while maintaining measurement precision.
Solution Approach 2:
The system transitions from static, permanently mounted sensors to a dynamic, reconfigurable platform. The mobile data acquisition unit can be installed, configured, and removed as needed, allowing the sensing system to adapt to different aircraft types and training requirements while maintaining high measurement accuracy through integrated inertial and GPS sensors.
3Use of energy by moving object
If data acquisition units require external power sources and wired connections to aircraft power supply, then power availability is ensured, but ease of operation and portability are reduced
Solution Approach 1:
The data acquisition unit incorporates an internal rechargeable battery that provides autonomous power supply, eliminating the need for external power sources or wired connections to aircraft power systems. This self-powered design enables the device to operate independently during flights and be easily transported between locations without requiring power infrastructure.
4Speed
If flight data is transmitted immediately to external systems for processing, then real-time feedback is provided, but loss of time for data storage and mobility occurs
Solution Approach 1:
The system performs preliminary data processing and buffering within the mobile acquisition unit during flight. Data is pre-processed, validated, and organized in the onboard memory before transmission, reducing the time required for post-flight analysis and enabling faster feedback cycles without sacrificing data quality or completeness.

AI summary
A low-cost training and synthetic visualization system and method directed to improving an individual's airborne performance in general aviation, skydiving, and other aerial applications. The system is comprised of a self-contained mobile sensor and data storage device for recording the travel path, orientation, and forces acting upon an object as it moves through space, a desktop graphics software program for creating a playback of the recorded data on a three-dimensional representation of the environment through which the object moved, a means of linking the sensor and data storage device to the software program for the purpose of exchanging information, and a centralized data storage and retrieval system designed to accept, assimilate and redistribute the recorded data.
