Conventional microscopes used in microinsemination require extensive optical element installation and removal for method switching, making it difficult to switch between observation methods quickly and efficiently, which can stress the egg and impact fertility rates.
Innovation Solution
A microscope design featuring a condenser turret with interchangeable optical elements and a drive control unit that allows for rapid switching between modulation contrast, differential interference contrast, and polarization observations by rotating the turret and adjusting the DIC prism and compensator, enabling quick method changes with minimal user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical elements are manually installed and removed for switching observation methods, then the microscope can perform multiple observation methods, but the switching time increases and egg stress increases
Solution Approach 1:
The condenser turret is designed to rotate between different positions, each holding a different optical element (apertured plate for RC observation, DIC prism for DIC observation). This dynamic switching mechanism allows rapid transition between observation methods without manual installation or removal of components, significantly reducing switching time and minimizing egg stress.
2Adaptability or versatility
If multiple optical elements are manually handled for method switching, then different observation methods can be implemented, but operational complexity increases
Solution Approach 1:
The rotating condenser turret provides a simple rotational motion to switch between different optical elements. The operator only needs to rotate the turret to the desired position rather than manually handling multiple optical elements, greatly simplifying the switching operation while maintaining the ability to perform multiple observation methods.
Solution Approach 2:
The condenser turret acts as an intermediary mechanism that holds and presents different optical elements to the optical path. This intermediary structure eliminates the need for direct manual handling of multiple optical elements, reducing operational complexity while enabling versatile observation methods.
3Adaptability or versatility
If extensive optical element installation and removal is performed, then multiple observation methods can be achieved, but egg stress increases impacting fertility rates
Solution Approach 1:
The dynamic rotating turret system allows rapid switching between observation methods, minimizing the time the egg is exposed to suboptimal conditions during method transitions. This reduces cumulative egg stress and improves fertility rates while maintaining the flexibility to use different observation methods as needed.
