Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing devices for retaining eyeglasses around the neck are inadequate for simultaneously securing multiple pairs, such as prescription and sunglasses, as they require selection and storage, which can lead to damage or loss, especially in situations without storage space.

Innovation Solution

A dual eyeglass retention device that connects two pairs of eyeglasses via bands, allowing one pair to be worn while the other is securely suspended against the user's body, eliminating the need for storage and enabling easy switching between pairs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a single band retention device is used, then the device structure is simple, but only one pair of eyeglasses can be retained

Engineering Contradiction:

Improvenumber of eyeglass pairs retainedVSAvoidretention device structure

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The retention device is divided into two separate bands (first band and second band), each capable of independently retaining a pair of eyeglasses. The bands are connected through a connection mechanism, allowing each band to function semi-independently while being part of a unified device. This segmentation enables the retention of multiple eyeglass pairs without requiring a completely complex new structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The retention device is designed to perform multiple functions: it can retain prescription eyeglasses, sunglasses, or any other eyeglass type on either band. The connection mechanism between bands allows the device to adapt to different usage scenarios, providing universal applicability for various eyeglass retention needs while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If unused eyeglasses are stored in a pocket, then storage is provided, but the eyeglasses may be damaged or broken

Engineering Contradiction:

Improveeyeglass safetyVSAvoideyeglass accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The invention extracts the unused eyeglasses from vulnerable storage locations like pockets and suspends them securely on the retention device around the user's neck. The bands and connection mechanism are designed to hold the eyeglasses in a protected position close to the body, eliminating the risk of damage associated with pocket storage while keeping them easily accessible when needed.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If traditional eyeglass cases are used, then storage is provided, but they are aesthetically unpleasing and prone to loss or theft

Engineering Contradiction:

Improveeyeglass protectionVSAvoidstorage solution

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention merges the retention function with the storage function into a single integrated device. The bands and connection mechanism serve both to retain the eyeglasses securely around the neck and to store them safely when not in use. This eliminates the need for separate traditional eyeglass cases, providing protection while maintaining aesthetic appeal and reducing the risk of loss or theft.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A retention device for two pairs of eyeglasses. A pair of retaining bands connect the opposite temples of each of the eyeglasses, so that when a user dons one of the pairs of eyeglasses, the other hangs against their person, thereby being protected, secured and readily available. In an alternate embodiment, a neckband is used from which retaining bands extend to secure two eyeglasses.
