Solution Overview

Problem

Existing eyewear technologies do not effectively combine functional lighting with aesthetic appeal, failing to provide both desired visual effects and user interaction.

Innovation Solution

Incorporation of light-emitting diodes (LEDs) with diffusers, such as anisotropic and prism-like diffusers, to create unique lighting patterns like a comet-like effect, which are controlled by a controller to indicate functionality and provide aesthetic characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If lighting is added to eyewear to improve functionality and aesthetics, then the visual appeal and user interaction are enhanced, but the device complexity and structural integrity are compromised

Engineering Contradiction:

ImprovefunctionalityVSAvoidstructural integrity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the lighting function with the existing eyewear structure by integrating LEDs and diffusers into the frame or lens assembly. The lighting components are merged with structural elements rather than added as separate attachments, thereby enhancing functionality while minimizing impact on structural integrity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lighting system serves multiple functions: it provides aesthetic illumination, indicates camera operation status, and enhances visibility. By making the lighting system multi-functional, the patent reduces the need for additional separate components, thereby maintaining structural integrity while achieving enhanced functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Shape

If diffusers are used to create unique lighting patterns, then the aesthetic appeal is enhanced, but the manufacturing complexity increases

Engineering Contradiction:

Improvelighting patternVSAvoidmanufacturing complexity

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

The patent employs diffusers with specific local optical properties to create desired lighting patterns. By varying the diffuser characteristics in different regions, the patent achieves aesthetically pleasing lighting effects without requiring complex overall manufacturing processes. The diffusers can be produced using standard optical manufacturing techniques with localized pattern variations.

Inventive Principle:

Principle #3Local quality
