Solution Overview

Problem

Conventional eyeglasses are bulky and prone to damage when stored, making them inconvenient for carrying and potentially damaging when kept in pockets or bags, especially for individuals who only need them for specific activities.

Innovation Solution

An extendable eyeglass apparatus with pivotally and slideably connected lens portions that transition between a stowed and extended configuration, featuring guide pins and channels for precise movement, and lanyard clips for secure attachment, allowing for compact storage and easy deployment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional eyeglasses are kept in pockets or bags for storage, then they are readily available for use, but they become bulky and prone to damage

Engineering Contradiction:

Improvedamage resistanceVSAvoidstorage size

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The eyeglass apparatus allows the second lens portion to be positioned within the plane of the first lens portion when stowed, creating a nested configuration that reduces storage volume while protecting the lenses from damage

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The eyeglass apparatus transitions between a stowed configuration (reducing volume and protecting lenses) and an extended configuration (enabling use), using movable connections and channels to dynamically change the spatial relationship between lens portions

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If eyeglasses are made compact for storage, then they are easier to carry, but they may become damaged during storage

Engineering Contradiction:

ImproveportabilityVSAvoidlens protection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The second lens portion nests within the plane of the first lens portion during storage, creating a compact configuration that is both portable and protective of the lenses from external damage

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The overlapping lens configuration acts as a protective barrier before damage can occur, with the lenses positioned to cushion and protect each other from external impacts during storage

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Adaptability or versatility

If eyeglasses are kept in pockets for specific activities, then they are convenient to access, but they occupy unnecessary space when not needed

Engineering Contradiction:

Improveactivity-specific useVSAvoidpocket space

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The eyeglass apparatus dynamically transitions between a compact stowed configuration (when not in use) and an extended functional configuration (when needed for specific activities), optimizing space utilization while maintaining activity-specific versatility

Inventive Principle:

Principle #15Dynamics

AI summary

An eyeglass apparatus comprises first and second eyeglass portions, each having a connector portion and a lens portion. The eyeglass apparatus is configured to transition between stowed and extended configurations. When the eyeglass apparatus is in the stowed configuration, the lens portions overlie one another. When the eyeglass apparatus is in the extended configuration, the lens portions are in a non-overlying configuration.
