Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple magnetic treatment apparatus is used, then the device complexity is reduced, but the positioning precision of the eye relative to the magnetic field generator deteriorates
Solution Approach 1:
The positioning member with offset eyecup is configured in advance to account for the anatomical offset between the orbital region and the eye center. This preliminary geometric compensation ensures that when the orbital region is positioned in the eyecup, the eye center automatically aligns with the magnetic coil center, achieving precise positioning without complex real-time adjustment mechanisms.
Solution Approach 2:
The positioning member acts as an intermediary component between the housing and the subject's orbital region. It includes a base attached to the housing and an eyecup configured to receive the orbital region, with the eyecup center offset from the base center to compensate for anatomical variations. This intermediary structure simplifies the overall system while ensuring accurate positioning.
2Ease of operation
If anatomical variations between subjects are not accounted for, then the ease of operation is improved, but the treatment reliability deteriorates
Solution Approach 1:
The positioning member incorporates an asymmetric offset design where the eyecup center is deliberately offset from the base center. This asymmetric geometry compensates for the natural anatomical offset between the orbital region and the eye center across different subjects, ensuring consistent and reliable positioning without requiring complex subject-specific adjustments.
Solution Approach 2:
The positioning member with its offset eyecup design serves as a universal solution that accommodates anatomical variations across different subjects. The fixed offset geometry provides a multi-functional approach that works for various eye positions and orientations, ensuring reliable treatment positioning for different individuals without requiring customization.
3Ease of operation
If the eye is not accurately positioned relative to the magnetic coil, then the ease of operation is maintained, but the treatment effectiveness deteriorates
Solution Approach 1:
The offset eyecup is pre-configured to establish the correct geometric relationship between the orbital region position and the eye center position. This preliminary action ensures that when the subject places their orbital region in the eyecup, the eye is automatically positioned at the optimal location relative to the magnetic coil, guaranteeing treatment effectiveness without requiring complex alignment procedures.
Solution Approach 2:
The positioning member with offset eyecup serves as an intermediary that translates the subject's orbital region position into the correct eye position relative to the magnetic coil. This intermediary structure ensures accurate treatment positioning while maintaining ease of operation, as the subject simply needs to place their orbital region in the eyecup without worrying about precise eye alignment.
