Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvemodular flexibilityVSAvoidsystem size
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
