Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are used to detect multiple attributes of matter, then detection capabilities are improved, but machine footprint increases
Solution Approach 1:
The patent combines a spectroscopy system and a laser triangulation system into a single integrated apparatus with overlapping detection zones. The light source arrangement emits both spectroscopy light beams and laser light through the same optical path, allowing multiple detection functions to be performed by a unified structure rather than separate sensors, thereby reducing the overall machine footprint while maintaining comprehensive detection capabilities.
Solution Approach 2:
The light source arrangement serves multiple functions by emitting different types of light (spectroscopy light beams and laser light) through the same optical path. The detection zones of both systems overlap, allowing a single apparatus to perform both spectroscopic analysis and triangulation-based spatial detection, making the system multi-functional and reducing the need for additional separate sensors.
2Area of stationary object
If multiple sensors are positioned close together to reduce footprint, then space utilization is improved, but sensor interference occurs
Solution Approach 1:
The patent employs optical filters with specific wavelength selectivity in the light paths of both the spectroscopy system and laser triangulation system. These filters allow only the relevant wavelengths to pass through to each detector, enabling the sensors to be positioned close together with overlapping detection zones while preventing cross-interference between the different sensing modalities through spectral discrimination.
3Device complexity
If separate detection zones are used for spectroscopy and laser triangulation, then system complexity is reduced, but apparatus size increases
Solution Approach 1:
The patent merges the detection zones of the spectroscopy system and laser triangulation system into overlapping regions. The light source arrangement emits both types of light through the same optical path, and the detectors are positioned to receive light from overlapping detection zones, creating a more compact integrated structure rather than requiring separate, non-overlapping detection areas.
