Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If components are arranged in an ad hoc manner in existing LiDAR assemblies, then the system can be assembled, but the components lack accessibility and removability, requiring disassembly of the entire system for maintenance or updates
Solution Approach 1:
The LiDAR system is divided into modular components (transmitter module, receiver module, control module, power module) that can be independently accessed and removed. Each module is mounted on separate brackets or plates that allow individual access without disassembling the entire system, enabling maintenance and updates of specific components while keeping other modules in place.
2Ease of manufacture
If components are arranged in an ad hoc manner, then the system can be assembled, but cables connecting components become messy, making assembly not production friendly
Solution Approach 1:
Cables connecting various modules are bundled together and routed through a cable management system that consolidates them into organized pathways. This merging of cable routes eliminates the messy appearance and simplifies assembly processes, making the system more production-friendly while maintaining all necessary electrical connections.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances maintenance and production efficiency by allowing easy replacement and upgrade of components, improving assembly accessibility, and reducing space occupied by modules through optimized cable routing.
Implementation Method 1
a typical LiDAR system measures the distance to a target by illuminating the target with pulsed laser light beams
Implementation Method 2
measuring the reflected pulses with a sensor such as a photodetector or a photodetector array
Implementation Method 3
The integrated transmitter-receiver module is configured to be assembled to or disassembled from the frame through guideways
