Augmented Reality Glasses With Damped Rotary Frame Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality glasses suffer from unstable and non-smooth engagement between the headgear and frame, leading to inconsistent alignment of the optomechanical assembly with the user's eyeball, which compromises the viewing experience.
Innovation Solution
The augmented reality glasses incorporate a rotary structure that connects the headgear and frame assembly, allowing for smooth rotation and synchronization of the optomechanical assembly, including a U-shaped frame with sub-rotary structures and a rotation transmission member to ensure the display is vertically aligned with the user's eyes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single screw fastener is used to connect the headgear and frame, then the structure is simple, but the rotation is not smooth and the degree of freedom is unstable
Solution Approach 1:
The connection structure is divided into multiple independent rotary joints (first rotary joint and second rotary joint) instead of using a single screw fastener. Each joint independently controls the rotation of the frame relative to the headgear, providing smooth rotation and stable degrees of freedom while maintaining structural simplicity
Solution Approach 2:
The connection structure transitions from a static single-screw fastener to dynamic rotary joints that enable smooth, multi-directional rotation. The rotary joints allow the frame to rotate freely relative to the headgear, providing stable degrees of freedom and smooth rotation control
2Adaptability or versatility
If the frame is at a large angle with respect to the headgear, then the adjustment range is increased, but the active display area cannot be parallel to the eyeball section, weakening the viewing experience
Solution Approach 1:
The frame is made dynamically adjustable through rotary joints that allow continuous rotation. The optomechanical assembly can rotate independently to maintain parallel alignment with the eyeball section regardless of the frame's angle relative to the headgear, ensuring precise display alignment across the full adjustment range
Solution Approach 2:
The alignment control is segmented into two independent rotation systems: the first rotary joint adjusts the frame angle relative to the headgear, while the second rotary joint adjusts the optomechanical assembly angle relative to the frame. This segmentation allows the display area to remain parallel to the eyeball section even when the frame is at large angles

AI summary
The present disclosure relates to the field of augmented reality technology, and in particular to augmented reality glasses. The augmented reality glasses include: a headgear assembly configured to secure the augmented reality glasses on a user's head; an optomechanical assembly; a frame assembly configured to carry the optomechanical assembly; and a damping rotary structure configured to rotatably connect the headgear assembly and the frame assembly such that when the augmented reality glasses are worn on a user's head, the user is allowed to see a picture displayed by the optomechanical assembly.
