Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic conductivity physical traction systems or detection instruments are deployed to achieve setpoint cruise, then navigation function is realized, but deployment cost increases and operation becomes complex
Solution Approach 1:
The patent uses visual copying by capturing images of the physical environment with a camera and creating a digital representation (map) of the track. Instead of deploying physical magnetic tracks or detection instruments, the system copies the visual appearance of the track into digital form, allowing the mobile device to navigate by matching visual features in the captured images against the stored map, thereby eliminating the need for complex physical infrastructure
Solution Approach 2:
The patent replaces mechanical/physical navigation systems (magnetic tracks, infrared sensors, ultrasonic sensors) with a vision-based computational system. The mechanical system of physical track laying is substituted by algorithmic processing of visual data, using image processing and feature matching algorithms to achieve navigation without any physical track infrastructure
2Reliability
If physical tracks are laid for navigation, then setpoint cruise is achieved, but environmental impact increases and operation becomes inflexible
Solution Approach 1:
The system creates a digital copy of the track environment through visual mapping, storing key feature points and map data in memory. This digital representation allows the mobile device to navigate accurately without any physical track infrastructure, eliminating environmental disruption while maintaining cruise accuracy through continuous visual feature matching against the stored map
Solution Approach 2:
The patent substitutes the mechanical physical track system with a software-based visual navigation system. Instead of relying on physical magnetic or optical tracks that disrupt the environment, the system uses computer vision algorithms to detect and track visual features in the natural environment, achieving accurate cruise control without any harmful environmental impact
3Reliability
If auxiliary equipment is deployed for navigation, then setpoint cruise is realized, but system cost increases
Solution Approach 1:
The patent makes the mobile device itself universal by equipping it with integrated camera, sensor, and processing capabilities that combine multiple functions (environment perception, mapping, navigation, and control) into a single device. This eliminates the need for separate auxiliary equipment such as external cameras, magnetic tracks, or detection instruments, reducing equipment quantity while maintaining navigation capability
Solution Approach 2:
The mobile device performs self-service navigation by using its own onboard camera and sensors to capture environmental data, process it through mapping algorithms, and determine its position and trajectory without requiring external auxiliary equipment. The device serves itself by independently completing perception, mapping, navigation, and control functions
4Reliability
If physical track systems are used for navigation, then cruise control is achieved, but adaptability decreases
Solution Approach 1:
The patent implements dynamic adaptability by allowing the virtual track to be flexibly modified through software updates. The mapping system can dynamically adjust to environmental changes, and the navigation algorithm can adapt to different track configurations without requiring physical track reinstallation. The system stores multiple map data and can switch between different virtual track configurations as needed
Solution Approach 2:
The system achieves adaptability by changing software parameters rather than physical infrastructure. The virtual track definition, mapping parameters, and navigation algorithms can be modified through software configuration, allowing the system to adapt to different environments and track layouts without physical modifications, thereby maintaining cruise control reliability while enhancing versatility
