Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If intelligent driving hardware and intelligent cockpit hardware are arranged separately, then each component can be independently designed and manufactured, but the overall hardware cost increases and maintenance and upgrading become inconvenient
Solution Approach 1:
The patent combines intelligent driving hardware and intelligent cockpit hardware into a single integrated controller unit. The controller includes a mother board with processing units, a daughter board with sensors and actuators, and a power supply unit, all integrated into one compact structure. This merging eliminates the need for separate independent controllers, reducing overall hardware cost and simplifying maintenance while maintaining independent design capabilities through modular board architectures.
2Adaptability or versatility
If intelligent driving hardware and intelligent cockpit hardware are arranged separately, then each component can function independently, but deep electronic and electrical integration is hindered
Solution Approach 1:
The controller employs a segmented modular architecture where the mother board contains processing units for intelligent driving functions, the daughter board houses sensors and actuators for cockpit functions, and the power supply unit provides dedicated power management. These segmented modules are electronically integrated through standardized connectors and communication interfaces, enabling deep integration while preserving independent functionality of each segment for easier maintenance and upgrading.
3Reliability
If separate hardware components are used for intelligent driving and cockpit functions, then system reliability can be maintained through component independence, but maintenance and upgrading become inconvenient
Solution Approach 1:
The controller implements a dynamic modular design where the daughter board can be easily detached from the mother board through standardized connectors. This dynamic interface allows maintenance personnel to access and replace specific components (such as sensors or processing units) without disassembling the entire controller, significantly improving maintenance convenience while maintaining system reliability through hot-swappable modular components.
