Eyeglasses Hat Mounting Tethers Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearers of eyeglasses face issues with glare, reflections, loss, and misplacement due to inadequate retention systems, which can lead to damage and difficulty in locating the glasses, especially during active movements or when removed from the head.
Innovation Solution
A system comprising mounting pins and flexible tethers that connect the temple arms of eyeglasses to a baseball cap, allowing adjustable placement and secure attachment, ensuring the eyeglasses remain with the hat, reducing glare, and making them easier to locate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If eyeglasses are retained using temple arms alone, then the structure remains simple, but the reliability of retention is insufficient during active movements
Solution Approach 1:
The patent combines the hat and eyeglasses into a single integrated system by attaching the eyeglasses to the hat bill using elastic bands that connect to the temple arms. This merging ensures that when the hat is worn, the eyeglasses are securely retained during active movements, solving the reliability issue without requiring a completely separate retention mechanism.
Solution Approach 2:
The patent introduces elastic bands as an intermediary element between the hat bill and the temple arms. These bands provide flexible connection that maintains retention reliability while accommodating movement, thus improving reliability without proportionally increasing complexity.
2Ease of operation
If eyeglasses are removed from the head, then comfort is improved, but the risk of loss increases
Solution Approach 1:
By merging the hat and eyeglasses into a single removable unit, the patent allows the user to remove both items together when comfort is needed. This maintains the anti-loss capability because the eyeglasses remain attached to the hat, eliminating the risk of leaving them behind while improving ease of operation.
3Reliability
If traditional retainers are used to secure eyeglasses, then retention is improved, but the ability to locate misplaced eyeglasses deteriorates
Solution Approach 1:
The patent merges the locatability of the hat with the eyeglasses. Since the eyeglasses are attached to the hat bill, they can be easily located by finding the hat. This resolves the contradiction by maintaining retention while dramatically improving locatability through the association with a larger, more visible object.
4Adaptability or versatility
If eyeglasses are kept separate from the hat, then each item can be optimized independently, but the risk of damage when misplaced increases
Solution Approach 1:
The patent combines the protective function of the hat with the eyeglasses. When both items are attached together, the hat provides a larger target area that is less likely to be stepped on or damaged, thereby protecting the eyeglasses from harm while maintaining the ability to independently optimize each component's design.
5Adaptability or versatility
If mounting pins are manually insertable at different locations, then adaptability is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent uses dynamic elements (elastic bands) that can accommodate different temple arm sizes and configurations without requiring precise manual adjustment of pin locations. The elastic bands naturally adapt to the geometry of the temple arms, maintaining adaptability while significantly improving ease of operation by eliminating complex installation procedures.
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 effectively retains eyeglasses on the head, reduces glare and reflections, prevents loss and damage, and facilitates easy location by keeping the eyeglasses connected to a more visible and protective hat, enhancing usability during sports and daily activities.
Implementation Method 1
Each of the bases is connected to a flexible tether, preferably an adjustable length loop and more preferably to an elastic loop. The elastic loop is preferably adjustable via a slide lock to allow each of the temple arms of eyeglasses to be inserted through a different loop.

AI summary
A hat has two flexible tethers each connected to a different temple arm of a pair of eyeglasses, with the tethers removably or permanently fastened to a bill of the hat. The two tethers are on opposing sides of the bill, with a first tether end of each tether preferably permanently connected a bottom side of the bill by stitching or a rivet. A second end of each tether has an opening sized to receive a temple arm passing therethrough during use and may have a slide lock to change the opening size to cinch the opening and second tether end tight against the temple arm. The stitching or rivet on the top of the bill may be covered by a top layer of material on the bill, or it may pass through that top layer of material. The rivet connection is useful with hard hats.
