Flip-up Eyeshield Assembly with Spring-Loaded Pivot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a device that allows for quick and hands-free transition of sunglasses from a use position to a non-use position while attached to a head covering, ensuring they do not obstruct the line of sight and providing convenient storage when not in use.
Innovation Solution
A flip-up eyeshield assembly with a pivot arm and latch surface that uses a biasing element, such as a torsion spring, to automatically pivot the eyeshield from a use position to a non-use position, keeping it attached to the brim of a head covering, allowing it to be easily moved between use and non-use positions without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sunglasses are removed from line of sight, then vision is unobstructed, but sunglasses require storage location
Solution Approach 1:
The patent combines the sunglasses with the head covering by providing a mounting structure that attaches the sunglasses to the brim. This merging eliminates the need for separate storage locations, as the sunglasses are always mounted on the head covering when not in use, resolving the contradiction between easy removal and storage convenience.
2Speed
If sunglasses are quickly transitioned to non-use position, then vision is restored, but manual operation is required
Solution Approach 1:
The patent implements a spring-loaded automatic return mechanism where the sunglasses automatically return to the non-use position after being pushed down into the use position. The spring-loaded mounting structure provides automatic resetting without requiring manual operation to return the sunglasses to their resting position, enabling self-service operation.
3Loss of time
If sunglasses remain attached to head covering, then storage is eliminated, but line of sight may be obstructed
Solution Approach 1:
The patent creates a dynamic mounting system where the sunglasses can move between two positions: a use position where they are pushed down in front of the eyes for sun protection, and a non-use position where they rest on the brim above the line of sight. This dynamic positioning allows the sunglasses to remain attached to the head covering while eliminating line of sight obstruction when not in use.
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
Enables convenient, hands-free operation of transitioning sunglasses between use and non-use positions, ensuring unobstructed vision and eliminating the need for storage when not in use, while maintaining attachment to the head covering.
Implementation Method 1
The biasing element includes a single torsion spring
Implementation Method 2
The biasing element is configured with a pre-loaded spring force to automatically pivot the pivot arm from the latched position to the released position without human intervention

AI summary
An eyeshield assembly configured to couple to a brim of a head covering includes a pivot arm with a latch surface. The pivot arm is configured to move between a latched position, when the eyeshield assembly is in a use position, and a released position, when the eyeshield assembly is in a non-use position. The eyeshield assembly also includes a latch arm with a distal end configured to receive the latch surface of the pivot arm when the pivot arm is in the latched position. Additionally, the eyeshield assembly includes a hinge assembly operably coupled to the pivot arm and including a biasing element. The biasing element is configured to pivot the pivot arm relative to the latch arm to move the pivot arm from the latched position to the released position without human intervention.
