Eyeglass Extensions with Converging Neck Rest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglass chains can be excessively long or short, leading to unwanted movement and entanglement issues when worn around the neck, causing discomfort and risk of impact with external objects.
Innovation Solution
The use of flexible silicone rubber extensions that attach to the temple tips of eyeglasses, allowing them to be worn around the neck with reduced mobility and without entanglement, by incorporating a cavity system that securely fits different temple tip sizes and orientations to prevent rotation and ensure stable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a chain is used to join the temples and allow eyeglasses to be worn around the neck, then the eyeglasses can be worn in a different position for ease of use, but the chain may be excessively long causing wide oscillations and risk of striking external objects
Solution Approach 1:
The patent changes the length parameter of the extension from excessive (chain) to optimized (extensions of appropriate length), reducing oscillation and impact risk while maintaining ease of use. The extensions are configured to rest behind the neck without being too long to cause harmful oscillations.
2Ease of operation
If a chain is used to join the temples and allow eyeglasses to be worn around the neck, then the eyeglasses can be worn in a different position for ease of use, but the chain may entangle and hold the eyeglasses causing discomfort
Solution Approach 1:
The patent extracts the entanglement problem by replacing the chain with extensions that have a different structural configuration. The extensions are designed to rest behind the neck and do not entangle, removing the harmful entanglement effect while preserving the ease of use benefit.
3Object-affected harmful factors
If extensions are used to attach to temple tips, then the mobility of eyeglasses is reduced and they can be supported on the neck, but the extensions must fit different temple tip sizes and orientations
Solution Approach 1:
The patent applies universality by designing extensions that can adapt to different temple tip sizes and orientations. The extensions are configured to securely fit various temple tips while maintaining their primary function of reducing mobility and supporting the eyeglasses on the neck.
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
This solution reduces the oscillation and entanglement of eyeglasses when worn around the neck, providing a comfortable and secure fit that prevents accidental impacts with external objects.
Implementation Method 1
The extensions are made of flexible silicone rubber and incorporate a cavity system that securely fits different temple tip sizes and orientations

AI summary
Eyeglasses (2) comprise a pair of extensions (1) configured to be fixed each to a respective temple tip (42) of the eyeglasses (2). Each extension (1) comprises a body (5), having a first segment (53) adapted to be fixed to a respective temple tip (42) of an eyeglass (2), and a second segment (54) inclined with respect to the first segment (53). When the first segments (53) are connected each to the respective temple tip (42), the second segments (54) project from the respective temple tips (42) in directions (T) converging with each other. In this way, the second segments (54) can rest on the neck of a user and support the eyeglasses at the neck without the use of a chain. The extensions (1) are adaptable to temple tips (42) of different sizes.
