Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional visual aid devices are used, then basic viewing correction is provided, but they cannot continuously diagnose and map the interior of the eye for precise visual correction
Solution Approach 1:
The patent divides the visual aid device into multiple independent components: a plenoptic lens array for capturing light field data, image capture devices for photographing the eye, processors for analyzing the data, and display devices for presenting corrected images. This segmentation allows each component to perform its specific function with high precision while maintaining overall system manageability.
Solution Approach 2:
The visual aid device integrates multiple functions into a single system: it captures eye images, maps the interior of the eye, diagnoses eye conditions, generates corrected images, and displays the results. This multi-functionality eliminates the need for separate diagnostic and corrective devices, reducing overall complexity while improving measurement precision.
2Reliability
If a plenoptic lens array is used to capture and map the interior of the eye, then continuous precise visual correction is enabled, but device complexity increases
Solution Approach 1:
The system performs preliminary mapping of the eye's interior structure before visual correction begins. The plenoptic lens array captures light field data and creates a detailed map of the eye's optical path, which is stored and used for continuous correction. This preliminary action enables reliable, continuous correction without requiring complex real-time recalibration.
Solution Approach 2:
The system continuously monitors eye characteristics using the plenoptic lens array and image capture devices, compares the current state with the mapped reference, and dynamically adjusts the displayed images to compensate for detected changes. This feedback loop ensures continuous reliable correction while using standardized components to manage complexity.
3Ease of operation
If multiple images are generated and presented to specific areas of the eye based on identified characteristics, then viewing ability is improved, but processing requirements increase
Solution Approach 1:
The system generates different images tailored to specific areas of the eye based on the mapped characteristics of each region. Each image is optimized for the local optical properties of the corresponding eye area, improving viewing ability by addressing local defects rather than applying uniform correction across the entire visual field.
Solution Approach 2:
The system processes and displays only the necessary portions of images for each viewing situation, rather than processing complete high-resolution images for the entire field of view. This partial action approach reduces processing power requirements while maintaining ease of operation for the user.
