Dual Eyewear Strap Merging Two Pairs Into Single Adjustable Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear holders require multiple straps and cases for multiple pairs of glasses, which are impractical and can lead to confusion and risk of damage or loss when quickly switching between different types of eyewear, such as sunglasses, safety glasses, and reading glasses.
Innovation Solution
A single strap with adjustable plastic or resilient material that splits into double strap ends with connectors to securely hold two separate pairs of eyewear, eliminating the need for multiple straps and cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate straps are used to hold multiple pairs of eyewear, then each pair of eyewear can be securely held, but the device complexity and ease of operation deteriorate due to needing to adjust and manage multiple separate straps
Solution Approach 1:
The patent combines multiple separate straps into a single integrated strap system. The single strap contains multiple pockets or compartments that can hold different pairs of eyewear, eliminating the need for multiple separate straps while maintaining secure holding capability.
Solution Approach 2:
The single strap is designed to serve multiple functions: it can hold different types of eyewear (sunglasses, safety glasses, reading glasses) simultaneously, and can be adjusted to accommodate various neck sizes and wearing preferences, making it a universal solution for multiple eyewear needs.
2Adaptability or versatility
If multiple separate straps are used to hold multiple pairs of eyewear, then each pair can be accessed, but the ease of operation worsens due to the need to adjust two separate straps for proper neck positioning
Solution Approach 1:
The patent merges multiple adjustment mechanisms into a single adjustment system. The single strap has one adjustment mechanism that controls the overall fit, and the eyewear are accessed by opening pockets or compartments rather than adjusting separate straps, simplifying the operation.
Solution Approach 2:
The strap is segmented into functional zones: a main adjustable section for neck fitting and separate pocket sections for holding different eyewear. This segmentation allows independent access to each pair of eyewear without affecting the overall strap adjustment.
3Reliability
If multiple eyewear cases are used to store different pairs of glasses, then the eyewear is protected, but the device complexity and loss risk increase due to managing multiple separate cases
Solution Approach 1:
The patent combines multiple separate cases into a single integrated strap with multiple pockets or compartments. Each pocket provides protection for a pair of eyewear while being part of a unified structure, reducing the number of separate components from multiple to one.
Solution Approach 2:
The design nests multiple pockets or compartments within the single strap structure, similar to nested dolls. Each pocket is contained within the overall strap boundary, allowing multiple eyewear to be stored in a compact, organized manner within one protective structure.
