Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If extensive map updates and costly components are used for environmental information, then navigation accuracy and environmental awareness are improved, but system cost and complexity increase
Solution Approach 1:
The patent introduces mobile terminals (smartphones, tablets) as intermediary devices that already possess navigation applications and environmental information capabilities. These terminals act as mediators between the vehicle system and the external environment, eliminating the need for the vehicle to carry extensive map databases and complex environmental sensing hardware. The mobile terminal's existing GPS, compass, and navigation software provide the required environmental information accuracy without increasing vehicle system complexity.
Solution Approach 2:
The patent leverages the universal nature of mobile terminals that already possess multiple functions including navigation, communication, and environmental sensing capabilities. By utilizing these multi-functional devices, the system avoids duplicating functionality with dedicated vehicle components, thereby reducing overall system complexity while maintaining environmental information accuracy through the terminal's integrated sensors and software.
2Reliability
If traditional vehicle-mounted communication systems are used, then reliable communication is achieved, but flexibility and ease of integration with mobile devices are reduced
Solution Approach 1:
The patent utilizes mobile terminals that already possess universal communication capabilities (cellular networks, Wi-Fi, Bluetooth) to handle both reliable vehicle-to-infrastructure communication and flexible device-to-device interaction. This multi-functional approach maintains communication reliability through established protocols while simultaneously providing adaptability to integrate with various mobile devices and communication standards without requiring dedicated vehicle-mounted communication hardware for each function.
3Reliability
If dedicated navigation hardware is installed in vehicles, then navigation functionality is ensured, but cost and ease of installation are worsened
Solution Approach 1:
The patent employs mobile terminals as intermediary navigation devices that drivers already possess and are familiar with. By utilizing the terminal's existing navigation application, GPS receiver, and display interface, the system ensures reliable navigation functionality without requiring installation of dedicated navigation hardware in the vehicle. This approach dramatically improves ease of manufacture and deployment, as no vehicle modification is needed—drivers simply use their personal devices.
Solution Approach 2:
The patent leverages the self-service capability of mobile terminals, which already contain all necessary navigation components (processor, memory, display, sensors, communication interfaces). The terminal independently performs navigation calculations, route planning, and guidance functions without requiring vehicle system integration or dedicated hardware installation. This self-contained approach ensures navigation reliability while eliminating installation complexity.
