Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conductive slip ring is used for charging the laser assembly, then power can be transmitted to the rotating laser transceiver, but the slip ring wears out which affects the life span and reliability of the product
Solution Approach 1:
The patent replaces the mechanical conductive slip ring system with a wireless charging system. The wireless charging assembly transmits power wirelessly to the rotating laser transceiver, eliminating the mechanical contact and wear associated with slip rings. This substitution of mechanical system with wireless energy transmission directly resolves the wear and reliability issue while simplifying the charging structure.
2Reliability
If mercury or noble metals are used in conductive slip rings to reduce wearing, then durability is improved, but environmental friendliness and cost become issues
Solution Approach 1:
The wireless charging system completely eliminates the need for conductive slip rings containing mercury or noble metals. By using electromagnetic field-based wireless power transmission, the patent removes the harmful materials from the charging mechanism, thereby improving environmental friendliness while maintaining durability through contactless power transfer.
3Measurement precision
If conventional lidar apparatus uses complex circuits and mechanical structures to achieve 360-degree view angle and high resolution, then scanning capability is improved, but manufacturing complexity and manpower consumption increase
Solution Approach 1:
The wireless charging assembly serves multiple functions: it provides power to the rotating laser transceiver, enables wireless communication, and simplifies the overall structure. This multi-functionality reduces the need for separate charging mechanisms and complex mechanical structures, thereby easing manufacturing while maintaining the 360-degree scanning capability through the rotating assembly.
