Engineering Contradiction Analysis
1Area of stationary object
If conventional beam plates are used to deliver laser beams to multiple target locations, then beam delivery is achieved, but the physical space required becomes excessively large
Solution Approach 1:
The beam delivery system is segmented into multiple beam-customized optical components (BCOCs), each responsible for controlling a specific optical beam. This segmentation allows parallel processing of multiple beams, enabling efficient delivery to multiple target locations while reducing the overall footprint of the system.
Solution Approach 2:
The patent transitions from a two-dimensional beam plate surface to a three-dimensional arrangement of optical components including relay optics and beam-customized optical components positioned at different heights and depths. This dimensional transformation enables compact beam delivery by utilizing vertical space and optical path folding, significantly reducing the horizontal surface area required.
2Reliability
If conventional beam plates are used for beam delivery, then optical beams can be delivered to target locations, but misalignment errors and noise are introduced
Solution Approach 1:
Each beam-customized optical component is designed with local quality optimization, incorporating specific optical elements (lenses, waveplates, mirrors) tailored to the requirements of its assigned beam. This localized customization enables precise control of each beam's properties and trajectory, minimizing alignment errors while maintaining manageable overall system complexity through modular design.
Solution Approach 2:
The system incorporates alignment feedback mechanisms where the position and orientation of each beam-customized optical component can be adjusted based on measured beam characteristics. This feedback loop enables real-time correction of misalignment errors, improving delivery precision while the modular architecture keeps the control system complexity manageable.
3Manufacturing precision
If beam-customized optical components are used to control optical properties, then precise beam delivery is achieved, but the device complexity increases
Solution Approach 1:
The beam-customized optical components are designed with universal interfaces and standardized mounting configurations, allowing the same physical platform to be used across all components. Each BCOC can perform multiple functions (beam steering, focusing, polarization control) through integrated optical elements, reducing the need for separate specialized components and thereby controlling overall system complexity while maintaining high precision.
