Motorized Optometry Apparatus with Integrated Trial Lens Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optometry equipment for measuring visual acuity is bulky, requires separate storage of trial lenses, and causes unwanted non-continuous correction power transitions due to manual lens changes, making it impractical for precise visual compensation.
Innovation Solution
The development of motorized optometry equipment with adjustable lenses that can modify spherical and cylindrical powers, allowing for continuous correction adjustments via a drive motor system, communication module, and image analysis for precise visual compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If trial lenses are placed on discs in refraction equipment, then visual acuity measurement is enabled, but the equipment becomes bulky and heavy
Solution Approach 1:
The patent merges multiple trial lenses into a single glasses frame structure, allowing multiple lens combinations to be integrated in one lightweight unit rather than requiring separate heavy discs for each lens configuration
Solution Approach 2:
The patent uses imaging technology to capture and analyze optical correction data, creating a digital representation of the measurement process that eliminates the need for physical handling of multiple heavy lens discs
2Stability of the object's composition
If trial lenses are stored in separate dedicated boxes, then lens organization is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple trial lenses into a single integrated glasses frame, eliminating the need for separate storage boxes and manual lens handling while maintaining organized access to different lens configurations
Solution Approach 2:
The glasses frame structure serves multiple functions simultaneously: it holds multiple trial lenses, provides structural support, and enables direct placement on the patient's face, replacing the need for separate storage and handling systems
3Adaptability or versatility
If manual lens changes are performed, then correction adjustments are possible, but non-continuous transitions and measurement time increase
Solution Approach 1:
The patent enables dynamic adjustment of trial lenses through motorized mechanisms that can continuously and precisely change lens positions and configurations, replacing manual discrete changes with automated continuous control
Solution Approach 2:
The patent implements continuous motorized control for lens adjustment, allowing smooth transitions between different correction powers without the interruptions and non-continuous jumps inherent in manual lens changing processes
4Adaptability or versatility
If motorized adjustment mechanisms are added, then continuous correction adjustment is enabled, but device complexity increases
Solution Approach 1:
The motorized mechanism serves multiple functions: it adjusts lens positions, changes lens configurations, and controls the timing of adjustments, consolidating what would otherwise require separate mechanical systems into a single integrated drive unit
