Foldable Augmented Reality Device with Rotating Lens Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality (AR) devices, particularly those designed for complex games or mixed reality experiences, are large and not portable due to the need for projecting images onto glass lenses, making them unsuitable for compact forms.
Innovation Solution
A foldable AR device design featuring a rotatable and foldable structure with a projector, support element, and lens module, utilizing pivot portions and a drive module to minimize volume, allowing the device to be easily carried and accommodated, with the projector and lens module capable of rotating to use or accommodation positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If images are projected onto glass lenses through a projection device to achieve complex AR experiences, then the AR functionality is improved, but the device size becomes large and portability is reduced
Solution Approach 1:
The device is divided into separable components: a spectacle frame portion and a lens module portion that can be worn separately or combined. The lens module containing the projection device can be detached from the spectacle frame, allowing users to wear only the lightweight frame or combine with the functional lens module based on usage needs.
Solution Approach 2:
The lens module is designed with rotatable and foldable structures that allow it to dynamically change its spatial configuration. The module can rotate around pivot points and fold against the spectacle frame, enabling the device to transition between an extended functional state and a compact portable state.
2Measurement precision
If a projection device and lens module are integrated into the AR device, then image projection capability is improved, but the device complexity and size increase
Solution Approach 1:
The lens module is designed to fold and nest against the spectacle frame when not in use. The projection device and lens assembly are contained within a compact housing that can be collapsed flat against the frame, similar to a nested doll structure where smaller components are contained within larger ones.
Solution Approach 2:
The lens module utilizes rotational degrees of freedom around pivot points to achieve compact storage. By rotating the lens module around a pivot axis and folding it against the frame, the device transitions from a three-dimensional extended configuration to a flattened two-dimensional configuration, effectively reducing its volume.

AI summary
An augmented reality (AR) device (100) includes a main body (10), a support element (20), and a lens module (30). The main body (10) includes a base (11), a projector (12), and a first pivot portion (13). The projector (12) is pivoted to the base (11) by using the first pivot portion (13), so that the projector (12) is capable of rotating relative to the base (11) by using the first pivot portion (13) as a first rotation axis (C1). The support element (20) is pivoted to a first end portion (111) of the base (11) and is configured to wear on a head of a user. The lens module (30) is pivoted to a second end portion (112) of the base (11) and the second end portion (112) is opposite to the first end portion (111). The lens module (30) is capable of rotating relative to the base (11) and being overlapped under the base (11). Through a rotatable and foldable accommodation structure, the augmented reality device (100) is easier to be carried and accommodated.
