Solution Overview
Problem
Existing eye training devices cause visual fatigue due to vergence-accommodation conflict and are either complex, immobile, or ineffective in directly improving eye muscle coordination, particularly for extraocular and intraocular muscles.
Innovation Solution
A mobile device with a laser beam generator and manipulator, controlled by a unit to move the laser beam in predetermined patterns, stimulating extraocular and intraocular muscles by tracking the beam with eye movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laser beam is moved in predetermined patterns to stimulate eye muscles, then eye muscle strengthening is improved, but device complexity increases
Solution Approach 1:
The device is divided into separate functional modules: a laser source unit, a manipulator unit with motors, and a control unit. This segmentation allows each component to be optimized independently and simplifies the overall system while achieving the complex function of predetermined laser beam movement patterns for eye muscle stimulation.
Solution Approach 2:
A manipulator mechanism acts as an intermediary between the laser source and the target surface. This manipulator, controlled by motors and guided by the control unit, translates electrical signals into precise mechanical movements, enabling the laser beam to follow predetermined patterns without directly coupling the laser with the movement control system.
2Manufacturing precision
If multiple mirrors and motors are used to move the laser beam, then laser beam movement precision is improved, but device size and complexity increase
Solution Approach 1:
Multiple functional elements (mirrors, motors, laser source) are merged into a compact integrated assembly. The manipulator combines positioning and orientation functions in a single mechanism, reducing the overall device volume while maintaining the precision required for accurate laser beam movement patterns.
Solution Approach 2:
The device utilizes rotational movements in multiple dimensions through the manipulator mechanism. By employing motors that can rotate the laser source and mirror assemblies in different planes, the system achieves precise three-dimensional beam positioning without requiring proportionally large linear travel distances, thus reducing overall device size.
3Adaptability or versatility
If a computer display and monitor are used for eye training, then visual stimulation is improved, but mobility is lost and visual fatigue increases
Solution Approach 1:
The invention extracts the essential function of visual stimulation from the computer display system and implements it through a portable laser beam projectable onto surfaces like ceilings or walls. This removes the dependency on stationary monitors and computers, providing the same eye-training visual stimulation in a mobile, portable format that can be used anywhere without causing the fatigue associated with prolonged computer use.
4Ease of operation
If the laser device is made mobile and compact, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The device replaces bulky mechanical positioning systems with electronically controlled motors that drive the manipulator. Instead of using complex mechanical linkages or manual adjustment mechanisms, the system uses motorized actuators controlled by electronic signals from the control unit, achieving compact mobility while managing mechanical complexity through electronic control.
