Adjustable Eyewear Temple with Internal Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglass temples are insufficient for maintaining glasses in place during strenuous activities, often being uncomfortable and aesthetically unpleasing, as they are either too rigid or have visible secondary cable temples when stored.
Innovation Solution
An adjustable eyewear temple system featuring a substantially rigid temple piece with a channel for a flexible cable temple that can be stored or deployed, allowing adjustment via an external piece, and optionally incorporating an elastic object to urge the cable into a deployed position, ensuring secure grip without visible secondary cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rigid temple piece is used, then the glasses are easy to place and remove, but the glasses cannot be securely retained during strenuous activities
Solution Approach 1:
The temple piece is segmented into a rigid outer temple for structural support and a flexible cable temple for secure retention. The flexible cable temple can be deployed from the rigid temple to engage behind the ear during strenuous activities, providing secure retention while maintaining ease of placement and removal.
Solution Approach 2:
The temple piece transitions from a static rigid structure to a dynamic system where the flexible cable temple can be deployed or stowed. This dynamic capability allows the glasses to adapt between normal use (rigid temple only) and strenuous activities (flexible cable deployed) to maintain both ease of operation and reliability.
2Reliability
If spring-hinged temples or cable temples are used to maintain glasses during strenuous activities, then retention is improved, but comfort and aesthetics are reduced
Solution Approach 1:
The flexible cable temple is nested within the rigid temple piece when not in use. This nesting allows the flexible cable to be completely concealed within the rigid temple's internal channel, eliminating visibility issues and maintaining aesthetic appearance during normal daily activities while providing retention capability when needed.
Solution Approach 2:
Different portions of the temple system have different properties: the rigid outer temple provides structural support and aesthetics for normal use, while the flexible cable temple provides secure retention when deployed. This local differentiation of properties allows the system to excel at both normal comfort and strenuous activity retention without compromise.
3Reliability
If secondary cable temples are stored in or along primary rigid temples, then retention capability is provided, but the secondary cables remain visible and reduce aesthetic quality
Solution Approach 1:
The flexible cable temple is nested within an internal channel of the rigid temple piece, completely concealing it from external view during normal wear. This internal nesting eliminates the aesthetic problem of visible secondary cables while maintaining the retention capability for strenuous activities.
Solution Approach 2:
The flexible cable temple is extracted from the traditional external attachment method and relocated to an internal position within the rigid temple structure. This extraction and repositioning eliminates visual visibility while preserving the functional retention capability when the cable is deployed.
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
The system provides secure retention during physical activities while maintaining a standard appearance during daily use, enhancing comfort and aesthetics by allowing seamless transition between stored and deployed positions.
Implementation Method 1
there is further an elastic object positioned within the channel between the flexible cable temple piece and an inner end portion of the channel. The elastic object compresses when the flexible cable temple piece is in the stored position and urges the flexible cable temple piece into the deployed position.
Data Source
AI summary
An adjustable eyewear temple system is disclosed. The system includes both a substantially rigid temple piece and a flexible cable temple piece, wherein the cable temple piece extends through a channel along the inside of the rigid temple piece. An adjustment piece allows the cable temple piece to be stored within the rigid temple piece when not needed. The system appears to a passerby as a standard temple piece due to the location of the channel and adjustment piece on the inside.
