Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing eyewear retainers do not adequately protect eyeglasses from scratching, require separate storage, and lack functionality for cleaning or serving as a fashion accessory.

Innovation Solution

A combination eyewear protector and wrist wrap constructed from fabric sheets with elastic cords and fasteners, allowing eyewear to be securely held and preventing temple pieces from contacting lenses, while also enabling cleaning and serving as a fashion accessory.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If eyewear is stored in pockets or bags, then storage is provided, but the temple pieces may contact the interior surface of the lenses and cause scratching

Engineering Contradiction:

Improvelens scratchingVSAvoidstorage structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The eyewear is nested within a protective case that is itself contained within the wrist wrap. The temple pieces are positioned within recesses or compartments that prevent them from contacting the lens interior surfaces, eliminating scratching while maintaining compact storage without requiring complex separate storage solutions.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The protective case and wrist wrap are merged into a single integrated device. The case is sewn or attached to the wrist wrap, combining protection, storage, and wrist-bearing functionality into one unit, eliminating the need for separate storage devices and reducing overall complexity.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If a protective cover is used, then lens protection is provided, but the device cannot serve as a fashion accessory or cleaning tool

Engineering Contradiction:

Improvemulti-functionalityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wrist wrap is designed to perform multiple functions: it serves as a protective case holder, a wrist accessory for fashion purposes, and includes a fabric surface that can function as a cleaning tool for the eyewear lenses. The fabric material is selected to be soft and non-abrasive, suitable for both protection and cleaning, thereby providing versatility without requiring additional specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If separate storage devices are used, then storage capacity is provided, but the association between case and eyewear is not maintained

Engineering Contradiction:

Improvecase-eyewear associationVSAvoidstorage system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The protective case and wrist wrap are merged into a single integrated unit, ensuring that the case and eyewear remain associated whenever the device is worn on the wrist. The case is permanently attached to the wrist wrap through sewing or other attachment methods, eliminating the need for separate storage devices and maintaining reliable association without increasing system complexity.

Inventive Principle:

Principle #5Merging (Combining)

4Ease of operation

If the device is worn on the wrist, then portability is improved, but the structure becomes more complex

Engineering Contradiction:

ImproveportabilityVSAvoidwrist wrap structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The wrist wrap serves multiple functions: it provides a wearable platform for carrying the protective case, acts as a fashion accessory, and includes fabric surfaces for cleaning. By consolidating these functions into a single simple wrist wrap structure rather than multiple separate devices, the overall complexity is reduced while maintaining ease of operation and portability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

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

Provides effective protection against lens scratching, eliminates the need for separate storage, and allows eyewear to be worn as a wrist accessory, offering versatility and convenience.

Implementation Method 1

an elastic cord with a cord lock and double strand slider are introduced around the top edge of the first and second sheets

Methodology Applied

Scientific EffectElasticity: Elasticity

Implementation Method 2

The material used for the construction of the eyewear protector and wrist wrap should be a soft cloth or fabric which is also strong, stretchable, washable, quick drying and does not scratch eyewear lenses

Methodology Applied

Scientific EffectFriction: Friction

AI summary

An eyewear protector and wrist wrap used with conventional eyeglasses, sunglasses, or eyewear in general, which can hold eyewear of varying size and shape and is made of a soft stretchable material. The device construction prevents the temple pieces of the eyewear from coming into contact with the interior surface of the lenses. An elastic drawstring assures that the eyewear be contained within the device and allows for the entire package to be hung from a wrist or from a pant belt loop. The device can be folded and with the aid of a strap having a fastener at one end which can engage with a fastener on the device, can be worn on a wrist as a wrist wrap. The device can be produced in countless colors and have logo labels or any matter of design placed onto it which is visible during both functions.
