Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ophthalmic devices integrate the specific light irradiation system with the microscope unit or pedestal, making it difficult to flexibly attach and detach according to user needs.
Innovation Solution
An ophthalmic device with a detachable imaging unit that includes a specific light irradiation system, allowing easy and selective attachment of the imaging unit to the main unit, comprising an imaging module and a specific light irradiation system that can be used independently of the main unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the specific light irradiation system is integrated with the microscope unit or pedestal, then the device structure is compact and unified, but the flexibility to attach and detach the specific light irradiation system according to user needs is reduced
Solution Approach 1:
The device is divided into a main unit (microscope unit) and a detachable imaging unit. The specific light irradiation system is integrated into the imaging unit rather than being permanently fixed to the main unit, allowing the imaging unit to be attached or detached based on user needs.
Solution Approach 2:
The imaging unit serves multiple functions: it contains both the imaging module for capturing eye images and the specific light irradiation system for illuminating the eye with specific wavelengths. This multi-functional design allows users to selectively attach the imaging unit when either imaging or specific light illumination is needed.
2Adaptability or versatility
If the specific light irradiation system is permanently integrated into the main unit, then the device operates reliably without attachment issues, but users cannot selectively use the device with or without the specific light irradiation system
Solution Approach 1:
The attachment configuration between the imaging unit and main unit is designed to be dynamically changeable. Users can attach the imaging unit when specific light irradiation or imaging is required, and detach it when these functions are not needed, providing operational flexibility while maintaining reliability during use.
3Adaptability or versatility
If the imaging unit is made detachable from the main unit, then the flexibility and adaptability of the device is improved, but the complexity of ensuring proper connection and operation increases
Solution Approach 1:
The device is segmented into modular components (main unit and imaging unit) with defined attachment interfaces. This segmentation allows the imaging unit to be easily attached or detached without affecting the main unit's operation, simplifying the attachment process despite the increased configurational flexibility.

AI summary
Provided is an ophthalmic device that makes it possible to easily and selectively attach a specific light irradiation system for emitting specific light. A slit-lamp microscope (100), which is an example of this ophthalmic device, comprises: a body part (10) having an illumination system (30) for irradiating an eye (E) being examined of a subject with illumination light and an observation system (40) for observing return light from the eye (E) being examined; and an imaging unit (60) that is detachably attached to the body part (10) . The imaging unit (60) has an imaging section (61) for acquiring an image of the eye (E) being examined and a background illumination system (80) for irradiating the eye (E) being examined with background light different from the illumination light.
