Attachable Strabismus Measurement Device With Variable Translucent Film
Solution Overview
Problem
Existing strabismus measurement devices lack a mechanism for alternate covering to detect latent strabismus and fail to provide information on which eye is fixating, leading to inaccurate diagnoses and cumbersome manual testing procedures.
Innovation Solution
A strabismus measuring device with a covering part, a covering control device, and a coupling part that can be attached to an eye-tracking device, featuring a variable translucent film switching between transparent and opaque states for each eye, enabling accurate Alternate Cover Test data transmission and easy attachment/detachment for use in infants and children.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual alternate covering is performed by the examiner, then strabismus can be detected, but the process is cumbersome and prone to errors due to variations in covering duration and measurement distance
Solution Approach 1:
The patent replaces the manual mechanical covering operation with an automated electronic covering mechanism. The covering and uncovering of the ocular lens are controlled automatically by a control unit that sends signals to the covering mechanism, eliminating the need for manual operation and ensuring consistent timing and duration of covering without human variation.
Solution Approach 2:
The system performs self-measurement by automatically tracking eye position and detecting strabismus without requiring continuous manual intervention. The eye-tracking device continuously monitors eye movements and the control unit automatically determines strabismus based on the tracking data, allowing the system to serve itself in the measurement process.
2Loss of information
If existing strabismus measurement devices are used, then eye movement analysis is available, but they lack alternate covering mechanism and fixation eye information
Solution Approach 1:
The patent combines the eye-tracking device with the covering mechanism into an integrated system. The covering mechanism is positioned to cover the ocular lens of the eye-tracking device, and the control unit coordinates the covering operation with the eye-tracking function, merging two separate functions into one unified diagnostic system.
Solution Approach 2:
The control unit acts as an intermediary that receives signals from the eye-tracking device, processes the eye position information, and controls the covering mechanism accordingly. It also generates the covering control signals and transmits diagnostic information, serving as the coordinating intermediary between the tracking and covering functions.
3Duration of action of stationary object
If the covering part is fixed and non-replaceable, then device structure is simple, but continuous use is limited when damaged or worn
Solution Approach 1:
The patent divides the device into separable components, with the covering part being a distinct module that can be detached and replaced independently from the main device body. The covering part includes the ocular lens and covering mechanism, which can be removed and replaced without affecting the core eye-tracking and control systems.

AI summary
Provided relates to a device for measuring ocular strabismus. More specifically, the ocular strabismus measuring device according to the present invention includes a covering part, a covering control device, and a coupling part. The device allows for the alternate cover test by selectively covering a variable translucent film controlled by the covering control device. It can be attached to and detached from an eye-tracking device, enabling alternate covering for each eye individually. The device transmits data on the covering state along with binocular eye deviation data to the eye-tracking device. The covering part is easily attachable and detachable, making the device useful for measuring strabismus in infants and children, and it allows for continuous use by replacing the covering part in case of damage or wear.
