Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing model eye apparatuses for intraocular lens evaluation fail to accurately compare different intraocular lenses due to the inability to capture distant or near objects or night distances in the same way, making it difficult to deliver realistic surgical outcomes to patients.
Innovation Solution
A portable model eye apparatus utilizing a beam splitter to emit light sources at right angles, paired with corneal and intraocular lens modules, and camera modules to capture images of intraocular lenses with different powers, ensuring identical imaging conditions for accurate comparison.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single portable model eye apparatus is used to evaluate intraocular lenses, then the device is portable and can be used in various environments, but it cannot capture distant or near objects or night distances in the exact same way for different intraocular lenses, making accurate comparison difficult
Solution Approach 1:
The patent divides the evaluation system into multiple independent portable model eye apparatuses, each dedicated to capturing a specific view (distant, near, night distance). This segmentation allows each apparatus to be optimized for its specific viewing condition while maintaining overall portability, resolving the contradiction between versatility and measurement precision.
Solution Approach 2:
The patent introduces a new dimension by adding multiple camera modules at different positions and orientations within the portable model eye apparatus. This dimensional expansion enables simultaneous capture of multiple views (distant, near, night distance) while maintaining portability, thus improving comparison accuracy without sacrificing mobility.
2Measurement precision
If multiple portable model eye apparatuses are used to capture different views for accurate comparison, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent merges multiple functional components (corneal modules, intraocular lens modules, camera modules) into a single integrated portable model eye apparatus. This consolidation achieves accurate multi-view capture while minimizing device complexity through unified design, avoiding the need for separate apparatuses for each viewing condition.
Solution Approach 2:
The portable model eye apparatus is designed with universal functionality to capture multiple types of images (distant, near, night distance) using a single device. This multi-functionality eliminates the need for multiple specialized apparatuses, reducing overall system complexity while maintaining high measurement precision through comprehensive viewing capabilities.
