Engineering Contradiction Analysis
1Adaptability or versatility
If multiple depth sensors are arranged to capture depth information from various locations, then depth detection coverage is improved, but device volume and weight increase
Solution Approach 1:
The patent employs a rotation mechanism that dynamically changes the orientation of the light source and reflective device to direct light beams toward different spatial locations. This dynamic adjustment allows a single depth sensor to capture depth information from multiple locations sequentially, replacing the need for multiple fixed sensors and thereby reducing device weight while maintaining comprehensive depth detection coverage.
