Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic-wave detection systems struggle to accurately distinguish multiple objects that overlap or cross each other in a captured image, leading to potential misidentification and inaccurate three-dimensional positioning.
Innovation Solution
The system employs a radiation system that radiates electromagnetic waves in different directions, a separation unit to separate reflected waves based on wavelength, and a switching unit to direct these waves to dedicated detection units, allowing for precise distance measurement and image capture, using a control unit to synchronize radiation and image acquisition to minimize timing discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single detector is used to detect electromagnetic waves, then the device complexity is reduced, but the ability to distinguish multiple overlapping objects deteriorates
Solution Approach 1:
The detection device is segmented into multiple independent detection units (first detector and second detector) that detect electromagnetic waves in different directions. Each detector is paired with a corresponding radiation unit that radiates waves in specific directions, allowing spatial separation of detection functions to distinguish overlapping objects.
Solution Approach 2:
The patent introduces a directional dimension to detection by using multiple radiation units that radiate electromagnetic waves in different directions (first direction and second direction). This adds spatial differentiation capability, transforming single-direction detection into multi-directional detection to resolve overlapping objects in three-dimensional space.
2Ease of operation
If radiation and image capture are performed without synchronization, then the operation simplicity is improved, but the measurement precision of three-dimensional positioning deteriorates
Solution Approach 1:
The control unit coordinates the radiation units and imaging unit through synchronized control, using feedback mechanisms to ensure that radiation and image capture occur at the same timing. This synchronization feedback loop eliminates timing discrepancies that would otherwise degrade three-dimensional positioning accuracy.
Solution Approach 2:
The control unit performs preliminary coordination to synchronize the radiation timing with image capture timing before the actual measurement process. This preliminary synchronization setup ensures that subsequent radiation and detection operations occur in perfect temporal alignment, enabling accurate three-dimensional positioning.
3Measurement precision
If multiple radiation units radiating in different directions are used, then the object distinction capability is improved, but the device complexity increases
Solution Approach 1:
The system is divided into paired modules where each radiation unit corresponds to a specific detection unit. This segmentation allows independent optimization of each radiation-detection pair while maintaining overall system coherence, managing complexity through modular design.
Solution Approach 2:
Multiple radiation units share common control infrastructure and detection processing systems. The control unit manages all radiation units uniformly, and the detection units process signals through a coordinated framework, allowing multi-directional radiation capability without linearly increasing overall system complexity.
