Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex sensor setups are used to detect equipment in simulation training, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent uses image capture devices (cameras) to create visual copies of equipment rather than attaching sensors directly to equipment. The system captures images of equipment in the real world and processes these images to detect equipment presence, position, and orientation, eliminating the need for complex sensor attachments while maintaining detection accuracy
Solution Approach 2:
The patent replaces mechanical sensor systems with an optical-based image processing system. Instead of using physical sensors to detect equipment, the system uses image capture devices to photograph equipment and computer vision algorithms to analyze the images, substituting a mechanical detection system with an optical-information processing system
2Measurement precision
If additional sensors are attached to equipment for detection, then measurement precision improves, but ease of operation deteriorates
Solution Approach 1:
The system creates visual copies of equipment through image capture and uses these copies for detection purposes. By processing images of the actual equipment rather than modifying the equipment with sensors, the original equipment remains unchanged and fully functional, maintaining ease of operation while achieving detection capabilities
Solution Approach 2:
The equipment detects itself passively through its visual characteristics in captured images. The system identifies equipment by analyzing visual features in images without requiring the equipment to actively transmit signals or have embedded detection components, allowing equipment to maintain its original simple operation while being detectable
3Reliability
If fixed-location simulation systems are used, then environmental fidelity improves, but adaptability deteriorates
Solution Approach 1:
The patent creates a universal simulation system that can operate in multiple locations (indoor ranges, outdoor ranges, various training facilities) using the same core components. The image capture devices and processing system are designed to work across different environments without requiring location-specific infrastructure, enabling the system to maintain environmental fidelity while adapting to various training locations
Solution Approach 2:
The system uses image capture devices as intermediaries between the physical training environment and the simulation processing system. These devices can be deployed in various locations to capture environmental data, which is then processed to create accurate simulations regardless of the original location, allowing the system to adapt to different training venues while maintaining environmental accuracy
