Solution Overview

Problem

Existing eye training devices cause visual fatigue due to vergence-accommodation conflict and lack effectiveness in directly improving coordinated eye muscle function, and are often cumbersome or not mobile.

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 requiring users to follow the beam with their eyes, allowing adjustable movement and size of the fixation target.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If 3D imaging and virtual reality are used for eye training, then visual stimulation is provided, but vergence-accommodation conflict occurs causing visual fatigue

Engineering Contradiction:
Improvevisual stimulation capabilityVSAvoidvisual fatigue
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces complex optical systems (3D imaging, virtual reality) with a simple laser point projection system. Instead of using displays that create vergence-accommodation conflict, the invention uses a laser device that projects a movable light point, eliminating the harmful visual effects while maintaining eye training functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts only the essential function of visual stimulation from complex VR/3D systems, isolating the core requirement (moving visual target) from the harmful components (displays causing vergence-accommodation conflict). This allows eye training without the associated visual fatigue.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If irritation generating devices are disposed around the eyeball, then eye movement is stimulated, but the accommodation system is not effectively engaged

Engineering Contradiction:
Improveeye movement stimulationVSAvoidcoordinated eye muscle function
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The laser device serves multiple functions simultaneously: it provides visual stimulation for eye movement and engages the accommodation system through the movable light point. This single device addresses both eye movement and accommodation coordination, unlike irritation devices that only stimulate movement.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses a dynamically movable laser point that can change position, size, and movement patterns. This dynamic target engages both the eye movement apparatus and the accommodation system, as the changing visual stimulus requires coordinated response from all eye muscle systems.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If multiple mirrors, motors and beam scattering media are used for laser beam control, then laser beam movement is achieved, but device complexity and size increase

Engineering Contradiction:
Improvelaser beam movement capabilityVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts only the essential function of laser beam movement from complex optical systems. Instead of using multiple mirrors, motors, and beam scattering media, the invention uses a simplified manipulator system with minimal components, reducing device complexity while maintaining functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces complex optical manipulation systems with a simpler manipulator mechanism. The manipulator directly controls the laser device position with fewer moving parts, eliminating the need for multiple mirrors and complex mechanical assemblies while achieving the same beam movement capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If stand alone monitors or displays are used for eye strain relief, then visual content is provided, but mobility is lost

Engineering Contradiction:
Improvevisual content deliveryVSAvoidmobility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The laser device integrates visual content delivery and mobility into a single portable unit. Instead of using separate stand-alone monitors, the invention combines the light source, manipulation system, and control functions in one mobile device that can be easily transported and used in various locations.

Inventive Principle:
Principle #6Universality (Multi-functionality)
