Eyeglass Support Strap for Rhinoplasty Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for supporting eyeglasses after rhinoplasty surgery often obstruct the downward field of vision, require alteration of the glasses, or are not adjustable to different head sizes, and may not be suitable for heavy surgical applications.
Innovation Solution
A head-encircling strap with a support member that holds glasses spaced from the nose, adjustable in length, and optionally includes padding and additional straps for comfort and easy attachment, allowing independent support for vision-enhancing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If support members are affixed to an eyeglass frame to support glasses off the bridge of the nose, then the glasses are kept away from the nose, but the support members obstruct the downward field of vision
Solution Approach 1:
The patent introduces a headband as an intermediary device that supports the eyeglasses without requiring attachments to the glass frame itself. The headband rests on the crown of the head and extends forward to support the glasses, thereby mediating between the head and the glasses while avoiding both nose contact and frame modification.
Solution Approach 2:
The support system is segmented into separate functional components: the headband portion that contacts the head, the support structure that holds the glasses, and the connection mechanism. This segmentation allows the support function to be separated from the eyeglass frame, eliminating the need for frame modifications while maintaining support stability.
2Reliability
If devices are attached directly to the eyeglasses to support them off the bridge of the nose, then the glasses are kept away from the nose, but the original style of the eyeglasses is destroyed and expensive replacement is required
Solution Approach 1:
The headband serves as an intermediary support device that does not require direct attachment to the eyeglass frame. Instead, it supports the glasses from above, preserving the original frame integrity and avoiding costly modifications or replacements.
Solution Approach 2:
The invention creates a separate support structure (the headband) that replicates the support function without modifying the original eyeglasses. This independent support system can be removed and transferred to different glasses, avoiding the need for permanent frame modifications.
3Reliability
If a fixed head-encircling device is used to support eyeglasses, then the glasses are supported off the nose, but the device cannot be adjusted to different head sizes
Solution Approach 1:
The headband incorporates adjustable elements including an adjustable strap with multiple length positions and flexible components that can adapt to different head circumferences. This dynamic adjustability allows the same device to accommodate various head sizes while maintaining stable glasses support.
Solution Approach 2:
The headband allows for parameter changes in length and configuration through adjustable straps and flexible components. These parameter adjustments enable the device to adapt to different head sizes and user preferences while maintaining the primary function of supporting eyeglasses off the nose.
4Ease of operation
If a simple strap is used to support eyeglasses, then the device is easy to use, but it cannot support heavy apparatus such as surgical light devices or magnifiers
Solution Approach 1:
The headband combines multiple support elements including head-resting portions, nose-avoiding support structures, and adjustable straps into a single integrated device. This merging of functions allows the device to handle heavier loads while maintaining ease of operation and adjustment.
Solution Approach 2:
The headband utilizes composite construction with multiple components made from different materials optimized for their specific functions - flexible materials for comfort and adjustment, and stronger materials for load-bearing support elements. This composite approach enables the device to support heavier apparatus while remaining easy to operate.

AI summary
A device for enhancing support of eyeglasses on the head of a person. The device is in the form of an independent support member or an adjustable strap having a support member to enhance support of eyeglasses. The strap may include a cushion to provide comfort. The support member includes a hook for supporting the eyeglasses. The device is useful for supporting eyeglasses from the bridge of the nose of a person who has undergone rhinoplasty surgery or for supporting heavy equipment associated with eyeglasses used for surgical applications. The independent support member is easily attached to a head-engaging device and eyeglasses to enhance support of the eyeglasses.
