Ophthalmic User-Profile Control for Ergonomic Refractive Surgery Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ophthalmic devices lack configurability, leading to discomfort and operational difficulties for users of varying heights, such as ophthalmologists and patients, during eye-surgical, therapeutic, and diagnostic procedures.
Innovation Solution
An ophthalmic apparatus with configurable components, including adjustable illumination, position-variable members, and a controller that adjusts these components based on user profile data to optimize user comfort and operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ophthalmic devices are made fixed and non-configurable, then device simplicity is maintained, but user comfort and operational ease deteriorate for users of varying heights
Solution Approach 1:
The patent applies the Dynamics principle by making the ophthalmic device height-variable through adjustable components. The device includes a height-adjustable headrest and position-variable members that can be moved along the longitudinal axis, allowing the device to adapt to different user heights and preferences, thereby improving user comfort without requiring complete device redesign for each user
Solution Approach 2:
The patent implements Parameter changes by allowing adjustment of key geometric parameters of the device, specifically the height of the headrest and the position of operational components along the longitudinal axis. These parameter adjustments enable the device to accommodate users of varying heights and ergonomic requirements, transforming a fixed device into a configurable one
2Productivity
If multiple users share a fixed ophthalmic device, then device simplicity is maintained, but adjustment time and operational efficiency deteriorate
Solution Approach 1:
The patent applies the Preliminary action principle by pre-configuring the device with adjustable components that can be quickly repositioned between users. The height-variable headrest and position-variable members are designed to be pre-adjustable to common height settings, allowing operators to rapidly switch between user profiles without extensive manual adjustment, thereby reducing adjustment time and improving operational efficiency
3Ease of operation
If ophthalmic devices are made height-variable with configurable components, then user comfort and ease of operation improve, but device complexity increases
Solution Approach 1:
The patent applies the Segmentation principle by dividing the height-adjustment functionality into separate, modular components: a height-adjustable headrest section and position-variable members that can be independently adjusted. This segmentation allows each component to be adjusted separately, simplifying the overall adjustment process and reducing the complexity burden of having multiple adjustable elements

AI summary
An ophthalmic apparatus includes a resting member configured to provide rest for a human patient, and an ophthalmic device configured to perform one or more procedures with respect to an eye of the patient resting on the resting member, where the one or more procedures include at least one of an eye-surgical, therapeutic and diagnostic procedure. The apparatus also includes a user interface device configured to receive log-in data from a user, and a controller configured to access stored user profile data based on the log-in data and configure one or more configurable components of the apparatus in accordance with the accessed user profile data.
