Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If discrete devices are used to build LiDAR system (computing processor, security MCU control processor, scanning control system, laser control system), then the system can be modular and flexible, but the LiDAR system becomes large in size and high in cost
Solution Approach 1:
The patent combines multiple discrete control devices (computing processor, security MCU control processor, scanning control system, laser control system) into a single integrated control chip. This merging of previously separate functional modules into one unified chip directly reduces the overall system size while maintaining the necessary control functions for LiDAR operation.
Solution Approach 2:
The integrated control chip performs multiple functions that were previously handled by separate devices: it serves as the computing processor, security controller, scanning controller, and laser controller all in one chip. This multi-functionality allows the system to maintain versatility and adaptability while reducing the number of discrete components needed.

AI summary
The present invention proposes a master control chip of a LiDAR and a LiDAR device. The master control chip of the LiDAR includes an execution control unit, a communication interface, an operation management unit and a function test unit. Main components of the execution control unit, the communication interface, the operation management unit and the function test unit of the LiDAR system are highly integrally designed, so that one chip completes functions such as ranging control, operation management and function detection that originally need to be implemented by one entire great system, thereby reducing design costs and a volume, and improving safety and reliability of the LiDAR system.
