Ophthalmic Apparatus Eye Positioning Detection Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmic apparatuses require manual dexterity and experience for precise positioning of a patient's eye relative to the treatment device, which can be cumbersome and imprecise.
Innovation Solution
An ophthalmic apparatus equipped with a detection device that records the eye's image to determine the required shift to achieve a nominal position, allowing for either manual or automatic adjustment of the positioning device to ensure precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning is used to position the eye relative to the treatment device, then the operator can control the positioning, but the positioning precision and ease of operation deteriorate due to requiring great experience and manual dexterity
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated image-guided positioning system. The detection device captures images of the eye and treatment device, and a control unit automatically calculates and executes positioning adjustments, substituting the manual mechanical operation with an automated optical-mechanical system that does not require operator experience or dexterity.
Solution Approach 2:
The patent uses image copying to enable precise positioning. The detection device creates visual copies (images) of the eye and treatment device positions, which are then processed by the control unit to determine the required shift. This copying approach allows precise measurement and positioning without direct manual manipulation.
2Productivity
If manual positioning is used, then the apparatus structure remains simple, but the positioning time and productivity worsen due to requiring operator experience and dexterity
Solution Approach 1:
The automated image-guided positioning system replaces manual positioning operations, enabling simultaneous image capture, processing, and positioning execution. This substitution eliminates the time-consuming nature of manual adjustment and significantly improves positioning efficiency without requiring operator experience.
Solution Approach 2:
The detection device captures images of the eye and treatment device positions in advance before the actual positioning operation. The control unit then processes these pre-captured images to calculate the required shift, enabling positioning to be executed without time-consuming manual measurement and adjustment during the procedure.
3Ease of operation
If an automated positioning system is implemented, then positioning precision and ease of operation improve, but the device complexity increases due to adding detection device and control unit
Solution Approach 1:
The detection device is designed to serve multiple functions: capturing images of both the eye and the treatment device, determining their respective positions, and providing data for shift calculation. This multi-functionality reduces the need for separate specialized components, thereby limiting the increase in device complexity while maintaining automated positioning capabilities.
Solution Approach 2:
The patent merges the detection, positioning calculation, and control functions into an integrated system. The control unit combines image processing, position determination, and positioning control in a single automated workflow, reducing the number of separate components and simplifying the overall apparatus structure despite the automation.
