Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle communication systems fail to account for datum differences in position information between navigation devices and central systems, requiring unnecessary conversion that complicates data transmission and processing.
Innovation Solution
An in-vehicle system with a position information reception unit, a first control unit connected to the reception unit, and a second control unit with a conversion process unit to convert and transmit position information data, enabling seamless conversion and transmission between different datum formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If position information is transmitted without datum conversion, then transmission simplicity is improved, but compatibility with systems using different datums deteriorates
Solution Approach 1:
The patent introduces a conversion process unit as an intermediary component that receives position information in one datum format and converts it to another datum format. This mediator enables compatibility between systems using different datums (e.g., WGS84 and JDZ2000) without requiring changes to the original position information source or the receiving systems, thus resolving the contradiction between transmission simplicity and datum compatibility.
2Adaptability or versatility
If a conversion process unit is added to enable datum conversion, then datum compatibility is improved, but system complexity increases
Solution Approach 1:
The conversion process unit is designed with multi-functionality, capable of handling multiple datum types (WGS84, JDZ2000, and other coordinate systems). By implementing a universal conversion mechanism that can process various datum formats through a single unified component, the patent reduces the need for multiple separate conversion modules, thereby minimizing system complexity while maintaining broad datum compatibility.
3Adaptability or versatility
If multiple control units with conversion capabilities are distributed, then system adaptability is improved, but configuration complexity increases
Solution Approach 1:
The patent divides the datum conversion functionality into separate, independent control units (first control unit and second control unit, each with its own conversion process unit). This segmentation allows different parts of the system to perform conversion independently based on their specific needs, improving system adaptability. The modular architecture enables flexible configuration where conversion capabilities can be distributed or centralized depending on the application requirements, without forcing a complex unified structure on all systems.
Data Source
AI summary
An in-vehicle system includes: a position information reception unit configured to receive position information from a satellite positioning system; a first control unit; a communication line connected to the first control unit; and a second control unit that is connected to the first control unit through the communication line and has a first conversion process unit configured to convert a datum of the position information. The first control unit is configured to transmit the position information received by the position information reception unit to the second control unit through the communication line, and the second control unit is configured to convert a datum of the position information received from the first control unit by the first conversion process unit.
