Suspended Optometry Units for Unobstructed Examiner View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optometric apparatuses obstruct the examiner's view of the subject's facial expressions during testing, limiting the accuracy of subjective measurements and occupying valuable space.
Innovation Solution
An optometric apparatus with a movement mechanism system suspended from an arm, allowing left and right optometry units to be moved independently, each equipped with optical element applying, target presenting, and objective measurement parts, enabling observation of facial expressions and efficient space use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the optometric apparatus is placed on the pedestal, then the measurement function is provided, but the examiner cannot observe facial expressions of the subject
Solution Approach 1:
The optometry units are made movable by suspending them from an arm that can rotate and position the units dynamically. This allows the apparatus to transition between different operational states: when needed for measurement, the units are positioned in front of the subject's eyes; when not needed, the arm can rotate to move the units out of the way, enabling the examiner to observe facial expressions without obstruction
2Reliability
If the optometric apparatus is placed on the pedestal, then the measurement function is provided, but the pedestal space is occupied
Solution Approach 1:
Instead of placing the optometry units horizontally on the pedestal surface, the units are suspended vertically from an arm that rotates along the pedestal's longitudinal axis. This dimensional reconfiguration allows the optometry units to be stored in a vertical orientation along the length of the pedestal rather than occupying horizontal surface area, thereby freeing up pedestal space while maintaining measurement functionality

AI summary
According to one embodiment, an optometric apparatus includes a movement mechanism system and left and right optometry units. The movement mechanism system is suspended from an arm. The left and right optometry units are configured to be moved by the movement mechanism system. The left and right optometry units each include an optical element applying part, a target presenting part, and an objective measurement part. The optical element applying part is configured to selectively apply a plurality of optical elements to a subject's eye. The target presenting part is configured to selectively present a plurality of visual targets to the subject's eye. The objective measurement part is configured for performing objective refraction measurement of the subject's eye.
