Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmologic systems require integration of ophthalmologic devices with phoropters, which is costly and impractical, and cannot accommodate users who do not need the ophthalmologic device.
Innovation Solution
An ophthalmologic device that can be detachably coupled to existing correcting devices, featuring a coupling member, a second optical element that branches a second optical path from the first optical path, and an objective measuring system to acquire ocular characteristics.

Engineering Contradiction Analysis
1Reliability
If an ophthalmologic device is integrated with a phoropter, then ocular characteristics can be measured continuously in real time, but the cost increases and existing phoropters must be replaced
Solution Approach 1:
The system is divided into separate functional modules: the existing phoropter remains independent while the ophthalmologic device (wavefront sensor) is detachably coupled to it. This segmentation allows the measurement system to be added only when needed, avoiding full system replacement and reducing overall cost while maintaining continuous real-time measurement capability when integrated.
Solution Approach 2:
The coupling between the ophthalmologic device and phoropter is made dynamic and adjustable rather than fixed. The detachable coupling mechanism allows the system to transition between integrated and separate states, enabling users to activate continuous real-time measurement only when required, thus balancing performance needs with cost considerations.
2Extent of automation
If an ophthalmologic device is integrated with a phoropter, then measurement feedback to the phoropter is enabled, but the system cannot accommodate users who do not need the ophthalmologic device
Solution Approach 1:
The system provides dynamic adaptability by allowing the ophthalmologic device to be coupled or decoupled based on user needs. When coupled, automatic feedback and measurement are enabled; when decoupled, the system reverts to basic phoropter functionality, accommodating users who do not require advanced measurement capabilities.
Solution Approach 2:
The phoropter system is designed to serve multiple functions: it can operate independently for basic visual correction examinations, or be coupled with the ophthalmologic device for advanced ocular characteristic measurement and automatic feedback. This multi-functionality increases versatility while controlling costs.
3Ease of manufacture
If manual entry of measurement results is required, then existing devices can be used separately, but continuous real-time measurement and direct feedback are not possible
Solution Approach 1:
The system separates the measurement function from the correction function, allowing existing phoropters to be used independently for basic examinations. When higher productivity is needed, the ophthalmologic device can be detachably coupled to enable automatic real-time measurement and feedback, eliminating manual entry requirements while maintaining compatibility with existing devices.
