Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple specialized measuring devices are used to measure different eye properties, then measurement accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by enabling a single measuring device to perform multiple measurement functions through detachable adapters. The basic device can measure axial distances, and by attaching different adapters (such as reflectometry adapters), it can also measure corneal curvatures and other eye properties, eliminating the need for multiple specialized devices while maintaining measurement accuracy
Solution Approach 2:
The patent applies segmentation by dividing the measurement system into a basic device and separate functional adapters. Each adapter is designed for a specific measurement type (e.g., reflectometry for curvature measurement), allowing the system to be configured flexibly by attaching only the necessary adapter for each measurement task, thereby reducing overall system complexity
2Adaptability or versatility
If a combination device is used to measure multiple eye properties, then versatility is improved, but the device diameter increases leading to ergonomic problems
Solution Approach 1:
The patent applies segmentation by separating the main device body from measurement functions, which are housed in detachable adapters. This allows the main device to remain compact and ergonomic, while versatility is achieved by attaching different adapters as needed, avoiding the need for a large integrated device diameter
Solution Approach 2:
The patent applies universality by designing a basic device that can accommodate multiple different adapters for measuring various eye properties. This modular approach provides versatility without requiring all measurement functions to be integrated into a single large device, thereby maintaining ergonomic performance
3Measurement precision
If a shorter working distance is used for measurement, then measurement accuracy is improved, but the risk of eye collision with the device increases
Solution Approach 1:
The patent applies dynamics by making the working distance adjustable through the use of detachable adapters that can be positioned at different distances from the eye. The system can dynamically adapt the measurement distance based on the specific measurement task and patient conditions, optimizing accuracy while minimizing collision risk

AI summary
The adapter (60) has a coupling unit (61) comprising a magnet, and a light conductor (62) for structured lighting of eye. Another light conductor diffuses or indirectly lights the eye, where the adapter is fastened at a measuring device (50) that comprises detectors i.e. image pickup unit, detecting property of the eye. A sensor recognizes the adapter, and a control unit switches a measuring mode for the property of the eye to a measuring mode for another property of the eye based on a measurement value of the sensor. An interferometer (54) is displaceable and/or swingable relative to the eye. The interferometer is designed as Michelson interferometer and Fourier domain interferometers. The sensor is designed as a signal transmitter. An independent claim is also included for a method for measuring properties of an eye.
