Eyeglass Arms with Dual-Axis Rotation for Salon and Traditional Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional eyeglass designs fail to address the challenges of accessibility and stability for individuals who need to see both near and far, particularly in situations where the ears are not accessible, and existing solutions like bifocals and lorgnette glasses have limitations such as glasses sliding down the nose or being used only in specific circumstances.
Innovation Solution
The multiuse eyeglasses feature a frame with arms that rotate on two axes, allowing for a hybrid configuration that enables the user to adjust the position of the lenses without removing the glasses, providing stability and versatility by allowing the arms to be rotated downwards relative to the frame, incorporating a hinge element with teeth and biasing springs for multiple predetermined positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional eyeglasses are worn with arms extended behind the ears, then the lenses are held securely in front of the eyes, but the glasses cannot be used when ears are not accessible (during hair dying, hair drying, surgery, etc.)
Solution Approach 1:
The eyeglass arms are designed to rotate between multiple positions (extended behind ears, folded against temples, downward salon position) allowing the device to adapt to different usage situations. This dynamic reconfiguration enables versatility without adding complex separate components.
Solution Approach 2:
The same eyeglass structure serves multiple functions: traditional wear behind ears, folded position for alternative earless wearing, and downward salon position for hair treatments. This multi-functionality resolves the contradiction between adaptability and complexity.
2Reliability
If bifocal or progressive lenses are used to see both near and far, then vision capability is improved, but the glasses slide down the nose when the user looks over them
Solution Approach 1:
The arms can rotate to a downward salon position that allows the lenses to remain at the correct height on the nose even when the user looks over the frames. This dynamic positioning prevents the glasses from sliding down while maintaining vision correction effectiveness.
3Adaptability or versatility
If lorgnette spectacles with handles are used for salon settings, then the lenses can be positioned correctly without ear support, but the design is only suitable for specific circumstances and lacks everyday versatility
Solution Approach 1:
The patent merges the traditional eyeglass structure with the lorgnette salon position capability into a single unified design. The arms can rotate to provide both traditional behind-ear support and downward salon positioning, eliminating the need for separate lorgnette glasses while maintaining salon functionality.
4Ease of operation
If traditional eyeglasses are folded for transportation and storage, then portability is improved, but the lenses cannot be adjusted to different positions while worn
Solution Approach 1:
The arms are designed with rotation capability that allows them to be folded for portability and extended or repositioned for different wearing situations. This dynamic design enables both compact storage and adjustable lens positioning while worn, resolving the contradiction between portability and adaptability.

AI summary
The multiuse eyeglasses include a frame that holds two lenses and arms that extend from the frame. The arms include a first axis of rotation that is generally perpendicular to the arms and a second axis of rotation that is orthogonal to the first axis of rotation and allows the arms to be rotated downwards relative to the frame.
