Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic connection strategy based on historical connection records is used, then connection automation is improved, but connection accuracy deteriorates due to frequent mismatches with actual driver's device
Solution Approach 1:
The system performs preliminary tracking of mobile device movement trajectories before connection is needed. By recording the movement paths of multiple devices in advance and identifying which device enters the vehicle area first, the system prepares the correct device identification beforehand, enabling accurate automatic connection without relying on potentially outdated historical connection records.
Solution Approach 2:
The patent replaces the traditional mechanical approach of manual connection or simple historical record-based automatic connection with an electronic tracking and analysis system. Using GPS or other positioning technologies to monitor device movement trajectories and automatically determine which device belongs to the driver substitutes the inadequate mechanical selection methods, achieving both automation and accuracy.
2Measurement precision
If manual connection method is used, then connection accuracy is maintained, but user convenience deteriorates due to required manual intervention
Solution Approach 1:
The system enables self-service automatic connection by autonomously tracking device movements, identifying the driver's device based on trajectory analysis, and establishing connections without any manual intervention. The system serves itself by automatically determining which device to connect and executing the connection process, eliminating the need for users to manually select or pair devices while maintaining high accuracy through trajectory-based identification.
3Device complexity
If simple historical connection record strategy is used, then device complexity is reduced, but service reliability deteriorates due to frequent connection failures
Solution Approach 1:
The system performs preliminary tracking and analysis of device movement patterns before connection is required. By continuously monitoring and storing trajectory data in advance, the system builds a reliable basis for identification that does not depend on complex real-time calculations or complicated connection strategies, achieving both simplicity and reliability.
Solution Approach 2:
The system incorporates feedback mechanisms by continuously monitoring device trajectories and using this information to accurately identify the driver's device. The trajectory data serves as feedback that reliably indicates which device belongs to the driver, enabling consistent and reliable automatic connections without requiring complex decision-making algorithms.
