Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If in-vehicle navigation map is updated by specialized technicians via 4S shops or repair shops, then map data accuracy is maintained, but updating cost increases and updating efficiency decreases
Solution Approach 1:
The patent enables the in-vehicle navigation device to autonomously connect with mobile terminals and perform self-updating of map data without requiring specialized technicians. The device automatically establishes connections, receives configuration files, downloads latest map data, and completes updates independently, thereby improving updating efficiency while maintaining data accuracy through automated verification processes.
Solution Approach 2:
The patent introduces mobile terminals as intermediary devices that facilitate map updates between the in-vehicle navigation device and map data sources. The mobile terminal acts as a mediator that enables communication and data transfer, allowing updates to be performed without direct intervention from technicians while ensuring data integrity through the structured interaction protocol.
2Reliability
If in-vehicle navigation map is updated by specialized technicians via 4S shops or repair shops, then map data accuracy is maintained, but updating cost increases
Solution Approach 1:
By enabling the navigation device to perform self-updating through automated connection and data reception processes, the patent eliminates the need for specialized technician services, thereby removing service fees and reducing updating costs while maintaining data accuracy through automated quality control mechanisms.
Solution Approach 2:
The patent utilizes mobile terminals that users already possess as copying devices to transfer map data to the in-vehicle navigation device. This approach replaces expensive professional service with a replicated capability using readily available personal devices, significantly reducing updating costs while ensuring data integrity through the structured data transfer protocol.
3Productivity
If in-vehicle navigation device connects with mobile terminal for self-service updating, then updating cost decreases and updating efficiency improves, but device complexity increases
Solution Approach 1:
The patent leverages the universal communication capabilities of mobile terminals (which users already possess) to perform map updates. By utilizing existing multi-functional devices for a specialized purpose, the patent avoids adding dedicated complex updating hardware to the navigation device, thereby improving updating efficiency while minimizing increases in system complexity.
4Reliability
If in-vehicle navigation device enables self-service updating, then updating frequency increases and map real-time performance improves, but operation complexity increases
Solution Approach 1:
The patent implements automated updating processes where the navigation device autonomously connects with mobile terminals, receives configuration files, downloads map data, and completes updates without user intervention. This self-service mechanism enables frequent updates and maintains real-time map performance while keeping operation simple for users.
Solution Approach 2:
The patent incorporates automated feedback mechanisms where the navigation device receives configuration files that specify what updates are needed, automatically verifies data integrity, and completes updates only when appropriate. This feedback-driven approach ensures real-time map performance while maintaining operational simplicity through automated decision-making processes.
