Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication devices with different protocols are mounted on a vehicle, then the functionality and versatility of the vehicle system is improved, but the communication compatibility and system integration complexity worsen
Solution Approach 1:
The patent introduces a gateway unit as an intermediary device that mediates communication between devices with different protocols. The gateway unit includes a transmission determination unit that receives signals from various devices, determines the appropriate transmission destination, and routes information accordingly. This mediator approach allows multiple protocol devices to coexist without direct compatibility requirements, resolving the contradiction between versatility and integration complexity.
Solution Approach 2:
The patent divides the vehicle communication system into modular segments, with each vehicle module containing its own gateway unit and communication devices. This segmentation allows each module to be independently configured and managed, reducing overall system integration complexity while maintaining the ability to support multiple protocols across the entire vehicle system.
2Reliability
If a traditional wired communication system is used to connect all devices, then communication reliability is improved, but the ease of installation and system flexibility worsens
Solution Approach 1:
The patent segments the communication system into modular vehicle modules that can be independently assembled and installed. Each module contains its own gateway unit and communication infrastructure, allowing for easier installation and maintenance while maintaining reliable wired connections within each module. The modular approach reduces installation complexity compared to a fully integrated wired system.
3Extent of automation
If vehicles are assembled by integrating all communication devices centrally, then system control is improved, but the productivity and assembly efficiency worsens
Solution Approach 1:
The patent divides the vehicle into multiple independently assemblyable modules, each with its own gateway unit and communication devices. This allows parallel assembly of multiple modules simultaneously, significantly improving productivity. The modular design maintains centralized control capability through the trunk line network that connects all gateway units, resolving the contradiction between automation control and assembly efficiency.
Solution Approach 2:
The patent enables preliminary assembly and testing of individual vehicle modules before final integration into the complete vehicle. Each module can be pre-configured and tested independently, reducing on-site assembly time and improving overall production efficiency while maintaining system control capabilities.
