Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an adjustment mechanism with multiple degrees of freedom is used to couple laser into fiber, then coupling efficiency can be ensured, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The patent extracts the complex multi-degree-of-freedom adjustment mechanism from the laser coupling system and replaces it with a simple fixed lens structure. The lens is directly mounted on the adapter housing without any adjustment mechanisms, thereby eliminating the complexity while maintaining coupling efficiency through proper optical design.
Solution Approach 2:
The system achieves self-alignment through the fixed optical path design. The lens position and orientation are predetermined during manufacturing to match the laser beam parameters, eliminating the need for manual adjustment during operation. The system serves itself by being pre-configured for optimal coupling.
2Reliability
If lens selection is made according to laser spot size and beam waist position to ensure coupling efficiency, then coupling efficiency improves, but adaptability decreases due to easy changes in laser parameters
Solution Approach 1:
The patent designs a universal adapter housing that can accommodate different laser types and parameters. The housing includes standardized interfaces and a lens selection mechanism that allows switching between different lenses to match various laser beam characteristics, making the system adaptable to multiple laser sources without requiring separate adapters for each laser type.
Solution Approach 2:
The system introduces dynamic adaptability through a lens selection mechanism that allows the user to switch between different lenses based on the laser parameters being used. This dynamic configuration capability enables the fixed structure to adapt to varying laser conditions, combining the stability of a fixed design with the flexibility needed for different laser types.
3Reliability
If optical path adjustment is performed manually to correct laser deviations, then coupling efficiency can be maintained, but loss of time increases due to frequent adjustments needed
Solution Approach 1:
The patent incorporates a feedback mechanism using a position detector to monitor the laser beam position in real-time. When deviations are detected, the system automatically triggers the adjustment mechanism to correct the beam alignment, maintaining coupling efficiency without requiring manual intervention. This closed-loop control eliminates the time loss associated with manual adjustments while ensuring stable coupling.
4Ease of operation
If a fixed structure with predetermined lens position is used, then ease of operation improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent performs preliminary action by pre-positioning the lens at the optimal location during the manufacturing process. The lens is mounted at a predetermined position and orientation that is calculated to match the expected laser beam parameters. This preconfiguration simplifies operation while the manufacturing precision requirements are managed through careful design and quality control during the assembly process.

AI summary
Disclosed are a laser adapter, a multiphoton microscope main unit, an optical system. The laser adapter includes: a shell, and a beam transformation device and a beam stabilization device, which are arranged in the shell. The shell is provided with a laser input port and a laser output port. The beam transformation device is configured to transform a laser beam that enters the shell. The beam stabilization device is disposed downstream of the beam transformation device in a laser transmission direction, and is configured to adjust the laser transmission direction, so as to correct a deviation between an actual position and an ideal position of the laser beam at the laser output port. When lasers with different parameters are input or a laser deflects during transmission, there is no need to readjust an optical path or replace an optical device on the optical path.
