Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic conductivity physical traction systems or detection instruments are deployed to achieve setpoint cruise according to preset trajectory, then the mobile device can follow a predetermined path, but additional equipment deployment is required resulting in high cost, complicated operation and inflexible usage
Solution Approach 1:
The patent creates a virtual copy of the physical track by generating a digital map and virtual trajectory from environmental features detected by the mobile device's existing sensors. Instead of deploying physical tracks or auxiliary detection equipment, the system copies the navigation function into software by recognizing natural environmental landmarks and creating a digital representation that guides the device along preset paths.
Solution Approach 2:
The mobile device uses its own built-in sensors (camera, GPS, inertial measurement units) to detect environmental features and construct the digital map autonomously. The device serves its own navigation needs without requiring external auxiliary equipment, eliminating the need for separate track-laying systems or additional detection instruments.
2Reliability
If magnetic conductivity physical traction systems or detection instruments are deployed to achieve setpoint cruise according to preset trajectory, then the mobile device can follow a predetermined path, but the operation is complex and the cost is high
Solution Approach 1:
The system replaces expensive physical track infrastructure with a software-based virtual track copied from environmental features. The digital map and virtual trajectory are created by processing images and sensor data from the mobile device itself, eliminating the need for costly physical track deployment and auxiliary detection equipment.
Solution Approach 2:
The mobile device performs multiple functions using its existing hardware: the camera and sensors used for other purposes are also employed for environmental feature detection, digital map construction, and navigation. This multi-functionality eliminates the need for dedicated navigation equipment, reducing overall system cost and simplifying implementation.
3Reliability
If magnetic conductivity physical traction systems or detection instruments are deployed to achieve setpoint cruise according to preset trajectory, then the mobile device can follow a predetermined path, but the operation is inflexible and additional deployment is required
Solution Approach 1:
The virtual trajectory is dynamically adjusted based on the constructed digital map and real-time environmental feature recognition. The system can adapt the navigation path by reprocessing environmental data and regenerating the virtual track, allowing flexible modification of the preset trajectory without physical track changes or complex reconfiguration procedures.
Solution Approach 2:
The system transitions from physical track dimension to digital map dimension for trajectory definition. By representing the navigation path as coordinates and features in a digital environment rather than physical markings, the system enables easy modification and adjustment of trajectories through software operations, providing flexibility across the digital domain.
4Reliability
If magnetic conductivity physical traction systems or detection instruments are deployed to achieve setpoint cruise according to preset trajectory, then the mobile device can follow a predetermined path, but high operating noise and environmental change are caused
Solution Approach 1:
The patent replaces mechanical physical track systems with an optical and computational system. Instead of using magnetic conductivity physical tracks that require physical deployment and generate operational noise, the system uses camera-based environmental feature detection and algorithmic digital map construction to achieve navigation, eliminating mechanical components and their associated environmental impacts.
5Measurement precision
If visible light camera or infrared thermal imager are used to patrol the line for setpoint cruise, then the mobile device can navigate using detection instruments, but auxiliary equipment deployment is required resulting in complex operation, high cost and no guarantee of environmental invariability and cleanliness
Solution Approach 1:
The mobile device uses its existing camera and sensors for both general operation and environmental feature detection for navigation. The same detection instruments serve multiple purposes, eliminating the need for dedicated auxiliary navigation equipment while maintaining environmental detection accuracy through multi-purpose hardware utilization.
