Eyewear Retaining Strap With Looped Material for Visible Item Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectacles do not effectively hold or secure items such as tools, access cards, or safety devices in a visible and accessible manner, often obscuring or impairing their functionality when stored in pockets or on belts.
Innovation Solution
Spectacles designed with a viewing lens, bracket, retaining strap, and fastening means, where the retaining strap comprises a soft, fuzzy material with looped elements like non-removable loops or mushroom-shaped fasteners, allowing secure and visible attachment of objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If items are stored in pockets or on belts for accessibility, then items are easily accessible, but visibility and electromagnetic functionality are obscured or impaired
Solution Approach 1:
The patent transitions item storage from traditional horizontal surfaces (pockets, belts) to a vertical dimension by attaching items to the retaining strap that hangs around the neck. This dimensional change allows items to be positioned in front of the body where they remain visible and electromagnetically accessible while maintaining easy physical access through the strap's proximity to the wearer.
Solution Approach 2:
The retaining strap acts as an intermediary carrier between the wearer and the items. Instead of items being directly stored in pockets or on belts, they are attached to the strap which serves as a mediating structure. This intermediary allows items to be positioned optimally for visibility and functionality while remaining easily accessible to the wearer.
2Adaptability or versatility
If spectacles are designed with additional attachment features for items, then item fixation is enabled, but device complexity increases
Solution Approach 1:
The retaining strap serves multiple functions: it retains the spectacles on the wearer's head, provides a mounting surface for various items through integrated fastening means, and acts as an adjustable length modifier. By combining these functions into a single component, the patent avoids adding separate attachment devices to the spectacles themselves, thereby maintaining simplicity while achieving versatility.
Solution Approach 2:
The patent merges the retention function and item attachment function into the retaining strap assembly. The fastening means are integrated directly into the strap rather than being separate components attached to the spectacles frame. This merging reduces overall device complexity by consolidating functions into fewer components.
3Ease of manufacture
If the retaining strap uses traditional smooth material, then manufacturing is simple, but item attachment stability is poor
Solution Approach 1:
The retaining strap is constructed as a composite structure combining a base fabric material with an overlaid loop material layer. The base material provides structural integrity and comfort, while the loop material layer provides secure attachment properties for items. This composite construction maintains ease of manufacture through layered assembly while dramatically improving item attachment stability through the mechanical interlocking capability of the loop structure.
Solution Approach 2:
The strap employs local quality differentiation by applying the loop material specifically to the outer surface where item attachment is needed, while the inner surface maintains smooth fabric for comfort against the skin. This localized application of different material properties optimizes both attachment reliability and manufacturing simplicity.
