Solution Overview

Problem

The functionality of eyewear with optical filters, such as sunglasses, is not easily perceivable indoors due to limitations in electronic displays that cannot accurately replicate natural scenes, leading to difficulty in demonstrating their features and benefits.

Innovation Solution

A system and method using an electronic display with high pixel density, luminance, and color gamut, along with image data that includes layers to enhance or attenuate specific spectral bands, to simulate the effect of optical filters on eyewear, allowing users to experience the filtering capabilities of eyewear even in indoor environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If eyewear with optical filters is demonstrated indoors using electronic displays, then the eyewear can be showcased in indoor environments, but the functionality and benefits of the optical filters are not readily perceivable

Engineering Contradiction:

Improveindoor demonstration capabilityVSAvoidperceivability of optical filter functionality

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent applies color changes by using image data with modified chroma values and spectral power distributions that simulate how optical filters enhance colors in natural scenes. The display shows images with enhanced saturation and contrast that mimic the visual effect of wearing eyewear with optical filters, allowing indoor viewers to perceive the color-enhancing benefits that would normally only be visible outdoors.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent changes parameters by adjusting the luminance, chroma, and spectral composition of the displayed images to match the characteristics of natural outdoor scenes. By modifying these parameters, the system creates visual stimuli that interact with the optical filters in eyewear to produce perceivable effects, overcoming the limitation of indoor lighting conditions.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If electronic displays are used to demonstrate eyewear functionality, then demonstrations can be performed indoors, but the displays cannot accurately replicate natural scenes

Engineering Contradiction:

Improveindoor demonstration capabilityVSAvoidaccuracy of natural scene replication

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent uses copying by creating digital images that replicate the spectral power distribution and chromatic characteristics of natural outdoor scenes. These copied natural scene characteristics are then displayed on electronic screens, allowing the display to simulate rather than perfectly replicate natural lighting conditions, enabling reliable demonstration of optical filter functionality indoors.

Inventive Principle:

Principle #26Copying

3Measurement precision

If image data with enhanced chroma and contrast is displayed, then the optical filter benefits are more perceivable, but the image may not accurately represent the original scene

Engineering Contradiction:

Improveperceivability of optical filter functionalityVSAvoidaccuracy of scene representation

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent applies segmentation by separating the image data into different spectral components and chroma layers. This allows selective enhancement of specific wavelength ranges that correspond to the optical filter's transmission characteristics, while maintaining accurate representation of other scene elements. The segmented approach enables targeted color enhancement without distorting the overall scene accuracy.

Inventive Principle:

Principle #1Segmentation
