Solution Overview

Problem

Existing devices that simulate the effects of intoxication, such as FATAL VISION goggles, do not effectively replicate the reduced peripheral vision associated with high blood alcohol concentration, which is a critical aspect of impairment that can go unnoticed by intoxicated individuals.

Innovation Solution

A peripheral vision reducing apparatus that attaches to existing impairment-simulating eyewear, featuring a light filter around the periphery of the Fresnel lens with adjustable apertures to simulate reduced peripheral vision by controlling the amount of light passing through, thereby enhancing the simulation of 'tunnel vision' effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing impairment-simulating eyewear (such as FATAL VISION goggles with Fresnel lenses) is used, then distorted vision and intoxication effects are simulated, but reduced peripheral vision (tunnel vision) associated with high blood alcohol concentration is not effectively replicated

Engineering Contradiction:

Improvesimulation accuracy of reduced peripheral visionVSAvoidcompatibility with existing eyewear devices

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The peripheral vision reducing apparatus is designed to attach to the front panel of existing impairment-simulating eyewear, with the light filter positioned around the periphery of the Fresnel lens. This nesting approach allows the new component to integrate with and enhance existing devices without replacing them, thereby improving simulation accuracy while maintaining compatibility.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The light filter is divided into multiple segments or zones that can independently control light transmission in different peripheral regions. This segmentation allows precise control over peripheral vision reduction while maintaining the central vision effects produced by the Fresnel lens, achieving both accurate tunnel vision simulation and compatibility with existing eyewear designs.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If a light filter is added around the periphery of the Fresnel lens, then reduced peripheral vision is simulated, but device complexity increases

Engineering Contradiction:

Improvesimulation accuracy of tunnel visionVSAvoidstructure complexity of eyewear assembly

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The light filter is integrated with the existing eyewear frame or front panel structure, merging the new peripheral vision reduction function with the existing device framework. This combining approach minimizes additional complexity by utilizing existing structural elements rather than adding completely separate components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The light filter is implemented as a thin film or flexible material that can be easily attached to the front panel around the Fresnel lens. This thin-film approach reduces structural complexity compared to rigid filters, allowing simple attachment methods and minimal interference with the existing eyewear design.

Inventive Principle:

Principle #30Flexible shells and thin films

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The apparatus effectively simulates reduced peripheral vision, allowing for a controlled and safe experience of the impairing effects of intoxication, enhancing educational and safety programs by providing a realistic simulation of high blood alcohol concentration without putting subjects at risk.

Implementation Method 1

The light filter portion can be substantially annular or ovoid. For each eye, the peripheral light filter defines at least one aperture in the middle of a user's visual field through which a first amount of light can pass. The light filter portions are also configured to permit a second amount of light to pass therethrough, the second amount of light being less than the first amount of light.
