Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solutions for holding eyewear and identification items simultaneously are bulky and impractical, particularly for individuals who need quick access to both, such as law enforcement and conference attendees, as they often require secure and easy access to vision correction and identification.

Innovation Solution

An adjustable sliding block with a neck strap and expandable connectors made from resilient materials, combined with a lanyard for identification, allowing for secure and convenient carrying of eyewear and identification items on a single strap.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate straps are used to hold eyewear and identification, then each item can be securely held, but the overall device becomes bulky and impractical

Engineering Contradiction:

Improvesecure holding of itemsVSAvoidbulkiness of straps

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent combines separate eyewear strap and identification lanyard into a single integrated strap system. The strap includes an eyewear retention portion with connectors for holding eyewear, and an identification portion with a lanyard for holding identification items, merging two separate functions into one unified device that reduces bulk while maintaining secure holding capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single strap is designed to perform multiple functions: it can hold eyewear through adjustable connectors, carry identification items via the lanyard portion, and provide quick access to both items. This multi-functional design eliminates the need for separate straps while maintaining reliability of item retention

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate straps are used to hold eyewear and identification, then both items can be held securely, but the device complexity increases

Engineering Contradiction:

Improvesecure holding of itemsVSAvoidnumber of straps

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple strap functions into a single strap structure that includes both eyewear retention capabilities with adjustable connectors and identification holding capabilities with a lanyard, reducing device complexity from multiple separate straps to one unified strap system

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single strap is designed as a multi-functional device that can securely hold both eyewear and identification items simultaneously, providing the same reliability as separate straps but with reduced complexity through consolidation of functions

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If eyewear cases are used to store eyewear, then eyewear is protected, but portability and quick access are reduced

Engineering Contradiction:

Improveprotection of eyewearVSAvoidquick access to eyewear

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of a rigid eyewear case, the patent uses a flexible strap with adjustable connectors that can quickly adapt to hold eyewear securely. The flexible nature of the strap allows for rapid deployment and adjustment, providing both protection and quick access unlike traditional hard cases

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The strap features adjustable and expandable connectors that can dynamically adapt to different eyewear types and sizes. This dynamic adjustment capability allows the strap to securely hold various eyewear while maintaining quick access, eliminating the need for fixed rigid cases

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If adjustable connectors are used to accommodate different users, then versatility is improved, but device complexity increases

Engineering Contradiction:

Improveaccommodation of different usersVSAvoidadjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The strap incorporates adjustable and expandable connectors that can dynamically change size and configuration to accommodate different user needs and eyewear types. This dynamic adjustability provides high versatility while keeping the mechanism simple through the use of expandable connector designs

Inventive Principle:

Principle #15Dynamics
