Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a light-emitting display module is mounted on the rotating LiDAR module, then user interface information provision is improved, but the device complexity increases
Solution Approach 1:
The LiDAR module is designed to serve dual functions: its primary function for navigation and mapping, and a secondary function as a rotating display platform. The light-emitting display module mounted on the LiDAR module utilizes the existing rotation mechanism to provide user interface information, thereby making the LiDAR module multi-functional without adding separate dedicated display hardware.
Solution Approach 2:
The display function is merged with the LiDAR module by mounting the light-emitting display module on it. Instead of having separate navigation and display systems, the patent combines these functions into a single integrated structure where the LiDAR module's rotation serves both navigation purposes and information display purposes simultaneously.
2Reliability
If proximity sensors are arranged to protect the LiDAR module, then reliability is improved, but the device complexity increases
Solution Approach 1:
Proximity sensors are positioned in advance around the LiDAR module to detect obstacles before they can cause damage. The sensors are pre-configured at strategic locations that allow them to detect potential collisions with objects above or near the rotating LiDAR module, enabling the system to take preventive action before damage occurs.
Solution Approach 2:
Proximity sensors act as intermediary detection elements between the LiDAR module and external obstacles. These sensors provide an early warning system that mediates the interaction between the rotating LiDAR module and its environment, allowing the control system to adjust operation or alert the user before actual damage can occur.
3Measurement precision
If the LiDAR module rotates for mapping, then measurement precision is improved, but the stability of the display module deteriorates
Solution Approach 1:
The display module is designed to dynamically adapt to the rotating LiDAR module's motion. Rather than attempting to maintain static stability, the system embraces the rotation by configuring the light-emitting elements to operate effectively during rotation, using the rotational motion itself as part of the display mechanism for providing user interface information.

Function Achieved in This Case
The solution enables the provision of various types of information to users through the light-emitting display module, uses proximity sensors for user input without affecting the LiDAR module's rotation, and protects the LiDAR module, thereby improving user interaction and cleaning efficiency.
