Rotatable Eyewear with Latching Hinge for Tilted Lens Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses designs with rigid mounting points cause instability when tilted for improved eye comfort and focus, leading to frequent adjustments and potential falling off.
Innovation Solution
A rotatable eyewear apparatus with a frame, temples, and hinges that allow lenses to be tilted to desired angles using a latching mechanism with stops, providing secure positioning and easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid mounting point is used to attach temples to the frame, then the structure is simple and stable, but the eyeglasses cannot be tilted to improve eye comfort and focus
Solution Approach 1:
The patent applies the dynamics principle by replacing the rigid fixed mounting with a rotatable hinge mechanism that allows the temples to pivot relative to the frame. This enables the lenses to be tilted to various angles to improve eye comfort and focus, while the hinge provides controlled movement rather than complete freedom of motion.
Solution Approach 2:
The mounting mechanism is segmented into multiple independent components: the frame, the temple, the hinge, and the latching mechanism. This segmentation allows each component to perform its specific function - the hinge enables rotation while the latching mechanism provides secure positioning at desired angles.
2Adaptability or versatility
If the temples are made rotatable to allow lens tilting, then eye comfort and focus improve, but the eyeglasses become unstable and may fall off
Solution Approach 1:
The latching mechanism engages in advance to secure the temple at a desired tilted position before the user wears the eyeglasses. This preliminary locking action ensures that once the temple is positioned at the optimal angle for eye comfort, it remains stable and will not unintentionally shift or cause the eyeglasses to fall off.
Solution Approach 2:
The spring-loaded latching mechanism automatically engages and disengages without requiring additional user action. When the temple is tilted to a desired position, the pawl automatically engages with the corresponding notch on the rotation stop, securing the position. The user can simply push the temple to release the latch when adjustment is needed.
3Stability of the object's composition
If a latching mechanism with multiple notches is added to secure tilted positions, then lens positioning stability improves, but the device complexity increases
Solution Approach 1:
The latching mechanism provides different qualities at different positions: multiple notches on the rotation stop allow for various tilted positions, each offering stable locking. The spring-loaded pawl provides consistent engagement force across all positions. This localized optimization at each positioning point achieves overall system stability without requiring a completely complex mechanism throughout.
4Ease of operation
If the temple is designed to fold for storage, then portability and storage convenience improve, but the structural complexity increases
Solution Approach 1:
The folding functionality is merged with the existing hinge mechanism. The same hinge that enables temple rotation for lens tilting also allows the temple to fold against the frame for compact storage. This dual functionality is achieved by incorporating a release mechanism that allows the hinge to move from its normal position to a folded position, eliminating the need for a separate folding mechanism.

AI summary
An apparatus includes a frame, a left temple, a right temple, a left end piece, a right end piece, a left hinge, and a right hinge. The frame includes a left side and a right side and the frame may support a plurality of lens. The frame of the apparatus that improves vision may be tilted to provide the lenses at varying angles and lock into place via a latching mechanism. The effect of the tilted lens provides significantly increased clarity and definition of vision, with no expensive custom lenses or magnification.
