Solution Overview

Problem

Conventional eyeglasses, such as bifocals, often cause discomfort and require multiple pairs for different vision corrections, leading to inconvenience and potential misplacement, especially when using sunglasses.

Innovation Solution

Design of eyeglasses with a movable platform and lenses that allow users to switch between different lenses by rotating them into and out of viewing positions, eliminating the need for multiple pairs and reducing the risk of misplacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If bifocals are used to correct multiple vision problems, then the need for multiple pairs of glasses is reduced, but user comfort deteriorates causing dizziness and sickness

Engineering Contradiction:

Improvevision correction capabilityVSAvoiduser comfort

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent divides the single bifocal lens into separate interchangeable lenses - a distance vision lens and a reading lens - that can be independently selected and positioned. This segmentation allows users to switch between different vision corrections without the visual disruption and discomfort associated with traditional bifocals, resolving the contradiction between versatility and comfort.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a dynamic lens positioning mechanism that allows users to move lenses between different positions (e.g., from a first position for distance vision to a second position for reading). This dynamic adjustment enables flexible adaptation to different viewing needs while maintaining visual comfort, unlike static bifocals that cause fixed visual disruption.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple pairs of glasses are carried for different vision needs, then adaptability to different vision problems is improved, but convenience deteriorates due to cumulative burden and misplacement risk

Engineering Contradiction:

Improvevision correction optionsVSAvoidcarrying convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines multiple lenses (distance vision lens, reading lens, and optionally sunglasses) into a single eyeglass frame with a unified lens positioning mechanism. Users can switch between different vision corrections by adjusting the lens positions rather than physically changing entire glasses, eliminating the need to carry multiple separate pairs and reducing misplacement risk.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The eyeglass frame is designed as a universal platform that can accommodate and switch between multiple types of lenses (distance, reading, sunglasses). This multi-functional design allows a single pair of glasses to replace multiple specialized pairs, improving convenience while maintaining adaptability to different vision needs and environmental conditions.

Inventive Principle:

Principle #6Universality (Multi-functionality)
