Eyeglass Arms with Dual-Axis Rotation for Adjustable Lens Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional eyeglasses designs fail to address the needs of users who require flexibility in viewing both near and far objects without compromising the glasses' position, as they either slide down the nose (bifocals) or are inconvenient in situations where the ears are inaccessible (e.g., hair drying, surgery).
Innovation Solution
The multiuse eyeglasses feature a frame with arms that rotate on two axes, allowing for a traditional, hybrid, and lorgnette configurations, enabling adjustable lens positioning without removing the glasses, with a hinge element and pivot screws facilitating distinct arm positions and a biasing spring system for secure, click-based adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional eyeglasses are designed with fixed arms, then the structure is simple and stable, but the user cannot adjust lens positioning without removing the glasses
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed arm structure into a dynamic, multi-position adjustable structure. The arms incorporate rotatable joints that allow movement between multiple predetermined positions (fully folded, partially folded, and fully extended), enabling the lens positioning to be adjusted without removing the glasses while maintaining structural integrity through defined mechanical stops at each position.
2Reliability
If bifocal 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 patent resolves this contradiction by enabling dynamic adjustment of the arm position. When the user needs to look over the glasses, they can rotate the arms to a partially folded position that lowers the lenses, maintaining proper optical alignment without the glasses sliding down the nose. This dynamic repositioning capability preserves both vision capability and position stability.
3Ease of operation
If traditional eyeglasses are worn during hair drying or surgery, then the glasses remain secure on the ears, but the user loses the ability to see and read when ears are inaccessible
Solution Approach 1:
The patent enables the arms to be rotated to a partially folded position that brings the lenses closer to the eyes without requiring the ears to be accessible. This dynamic adjustment allows users to maintain vision functionality in scenarios like hair drying or surgery where traditional ear-based securing would fail, while the glasses remain securely positioned through the mechanical joint structure.
4Adaptability or versatility
If the arms are made fully rotatable to provide positioning flexibility, then adaptability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the arm structure into multiple segments connected by rotatable joints. Each joint provides rotation between predetermined positions defined by mechanical stops, breaking down the complex fully-rotatable requirement into manageable discrete positions. This segmentation maintains adaptability while simplifying manufacturing compared to continuous rotation mechanisms.
Solution Approach 2:
The patent implements a dynamic hinge mechanism that allows rotation between predetermined positions rather than continuous rotation. The mechanical stops at each position provide natural manufacturing targets for alignment and assembly, reducing the precision requirements compared to fully continuous rotation while still providing the necessary positioning flexibility for multiple use scenarios.

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.
