Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the OCT measurement light optical system is integrated with the observation optical system in a Galilean-type ophthalmic microscope, then the system can be compact, but the design freedom and independence between systems are limited
Solution Approach 1:
The patent divides the optical system into separate modules: the observation optical system and the OCT measurement light optical system are independently designed and then combined. This segmentation allows each subsystem to be optimized independently while maintaining overall compactness through modular integration.
Solution Approach 2:
The OCT measurement light optical system is nested within the observation optical system structure. The measurement light path is arranged to share space with the observation light path through careful optical design, allowing the OCT system to be embedded without significantly increasing the overall microscope volume.
2Volume of moving object
If the OCT measurement light optical system is integrated with the observation optical system, then space is saved, but the ease of attachment and detachment of function expansion units is reduced
Solution Approach 1:
The function expansion unit containing the OCT measurement light optical system is designed as a detachable module that can be attached to or removed from the main observation optical system. This modular segmentation enables easy attachment and detachment while maintaining compact integration when assembled.
Solution Approach 2:
The system transitions from a fixed integrated design to a dynamic modular configuration. The function expansion unit can be dynamically attached or detached based on operational needs, providing flexibility while maintaining compactness when the unit is attached.
3Adaptability or versatility
If the OCT measurement light optical system is designed independently from the observation optical system, then design freedom increases, but the system complexity and size increase
Solution Approach 1:
By segmenting the optical systems into independent modules, each can be designed and optimized separately, reducing the complexity of integrated design while maintaining overall system functionality. The separate design allows for specialized optimization of each subsystem.
Solution Approach 2:
The modular function expansion unit with the OCT measurement light optical system can be applied to different observation optical systems, providing universal compatibility. This multi-functionality reduces overall system complexity by using standardized modules rather than custom-integrated designs.
