Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired diagnostic communication is used for software updates, then connection reliability is improved, but update speed deteriorates
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The in-vehicle gateway uses wireless communication modules to transmit software update data to ECUs, eliminating the need for physical cable connections while maintaining communication reliability through protocol design and error correction mechanisms.
2Stability of the object's composition
If wired diagnostic communication is used for software updates, then communication stability is improved, but user convenience deteriorates
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The in-vehicle gateway uses wireless communication modules to transmit software update data to ECUs, eliminating the need for physical cable connections while maintaining communication reliability through protocol design and error correction mechanisms.
Solution Approach 2:
The system enables automated software updates where the gateway automatically receives update information from servers and distributes it to relevant ECUs without requiring user intervention or visits to service centers, making the update process convenient and self-service oriented.
3Productivity
If automated wireless update system is implemented, then update efficiency is improved, but system complexity increases
Solution Approach 1:
The patent divides the software update system into distinct functional modules: a communication module for wireless data transmission, a control module for managing update processes, and individual ECU units for receiving and installing updates. This segmentation allows each component to perform its function independently, simplifying the overall system architecture despite the automated capabilities.
Solution Approach 2:
The in-vehicle gateway is designed as a universal device that handles multiple communication protocols and can update various types of ECUs through a single wireless interface. The gateway serves multiple functions including data reception, processing, and distribution to different control units, reducing the need for separate specialized devices.
