Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate devices are used for different ophthalmic technologies, then each device can be optimized for its specific function, but the floor space requirement increases and procedure time increases
Solution Approach 1:
The patent combines multiple ophthalmic diagnostic and treatment devices into a single integrated device. The housing contains multiple optical systems (topography system, Scheimpflug system, wavefront system, OCT system, laser treatment system) that share common components such as the radiation interface, optical path, and control unit. This merging eliminates the need for multiple separate devices, reducing floor space requirements while maintaining functional optimization through dedicated optical paths for each system.
Solution Approach 2:
The integrated device provides universal functionality by incorporating multiple ophthalmic technologies in one system. The device can perform corneal topography, anterior segment imaging, wavefront analysis, OCT imaging, and laser treatment through a single unified platform. The radiation interface and optical path are designed to accommodate multiple optical systems, allowing the device to serve multiple diagnostic and treatment functions without requiring separate specialized devices.
