A redundant architecture LiDAR system is designed with dual components for LiDAR devices, data processing units, and power components, allowing for continuous operation even if one component fails, ensuring reliable data transmission to external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single LiDAR component and single data processor are used, then the device complexity is low, but the reliability of data transmission deteriorates due to potential component failures
Solution Approach 1:
The LiDAR system is divided into multiple independent components: first and second LiDAR components for sensing, first and second data processors for data handling, and dual power components for power supply. Each segment can operate independently, ensuring that failure of one segment does not compromise the entire system's data transmission reliability.
Solution Approach 2:
The patent implements redundancy by providing backup components (second LiDAR component, second data processor, and dual power components) that can take over when primary components fail. This beforehand cushioning ensures continuous operation and maintains data transmission reliability even when components malfunction.
2Reliability
If redundant components are added to the LiDAR system, then the reliability of data transmission is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into integrated components. The first and second power components can both supply power to the LiDAR device and data processor, combining power supply functions. The LiDAR components and data processors are integrated into a cohesive system where redundancy is achieved through functional merging rather than separate independent systems.
3Reliability
If dual power components are used to ensure continuous operation, then the reliability is improved, but the loss of energy increases due to redundant power consumption
Solution Approach 1:
The power management system dynamically switches between first and second power components based on operational needs and component status. When one power component fails or is insufficient, the system automatically transitions to the other power component, ensuring continuous operation while optimizing energy utilization and avoiding unnecessary energy consumption from simultaneously operating both power components.
