Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate imaging devices are used for ocular topography and aberrometry, then functional versatility is improved, but measurement precision deteriorates due to alignment requirements
Solution Approach 1:
The patent combines ocular topography and aberrometry imaging functions into a single imaging device that captures both types of data simultaneously. This eliminates the need for separate imaging devices and their associated alignment requirements, while maintaining full functional versatility for both topography and aberrometry measurements through unified optical path and detector system.
Solution Approach 2:
The imaging device is designed with multi-functionality to perform both ocular topography and aberrometry measurements using the same optical system and detector. The device can selectively capture reflected light patterns for topography or wavefront information for aberrometry, providing universal measurement capability without requiring separate specialized devices.
2Loss of information
If multiple imaging devices are used to provide comprehensive ocular data, then information completeness is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple imaging functions into a single integrated device that captures both topography and aberrometry data through one optical system and detector, eliminating the complexity of coordinating multiple separate devices while maintaining complete ocular information acquisition.
Solution Approach 2:
The single imaging device is designed with universal capabilities to extract both topographic surface information and aberrometric wavefront data from the same optical path, reducing device complexity by eliminating redundant components while preserving information completeness.
3Measurement precision
If separate detectors are used for topography and aberrometry, then measurement comprehensiveness is improved, but alignment precision requirements increase
Solution Approach 1:
The patent merges topography and aberrometry detection into a single detector system that processes both types of measurements simultaneously, eliminating the need for precise alignment between separate detectors while maintaining comprehensive measurement capability through unified data acquisition.

AI summary
Improved systems and methods for ocular topography and using a plenoptic detector are provided. For example, a multifunction ocular topography and aberrometry system can comprise a first set of light sources, a second light source, a plenoptic detector and a processing system coupled to the plenoptic detector. The first set of light sources and the second light source are configured to selectively illuminate an eye. The plenoptic detector is configured to selectively receive images of the first set of light sources reflected from a corneal surface of the eye and generate first plenoptic image data representing the images of the first set of light sources. The plenoptic detector is further configured receive images of the second light source reflected from a retina of the eye and generate second plenoptic image data representing the images of the second light source.
