Foldable VR Viewer with Tension Mechanism for Lens Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual-reality or augmented-reality viewers for mobile devices often obscure or block input and output mechanisms, are bulky, difficult to carry, and lack lens protection, making them inconvenient and prone to damage.
Innovation Solution
A virtual-reality or augmented-reality viewer design featuring a central body with lenses, side bodies that can move to expose input and output mechanisms, and a tension mechanism allowing the viewer to switch between closed and open states for improved portability and lens protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the viewer surrounds most of the mobile device to securely hold it, then the device is securely held, but the input and output mechanisms and ports are obscured or blocked
Solution Approach 1:
The viewer is divided into a central body and two separate side bodies that can be independently positioned. The side bodies can be folded away or positioned to not interfere with access to input and output mechanisms, while the central body maintains device holding security.
Solution Approach 2:
The side bodies are made movable relative to the central body, allowing them to be folded away when not needed for lens protection. This dynamic configuration enables the viewer to adapt between providing full coverage and providing access to device mechanisms.
2Ease of operation
If the viewer is designed to be compact and collapsible for portability, then portability is improved, but lens protection is reduced
Solution Approach 1:
The side bodies can be folded against the central body for compact storage and portability, or extended out to provide lens protection when the viewer is in use. This dynamic structure allows the same device to achieve both compactness and protection.
Solution Approach 2:
The side bodies can be folded or nested against the central body when not in use, creating a compact form factor for portability, while being available to extend out for lens protection when needed.
3Object-affected harmful factors
If the side bodies are extended to provide lens protection, then lens protection is improved, but the viewer becomes bulkier and less portable
Solution Approach 1:
The side bodies are designed to be extended only when lens protection is needed during viewing. When collapsed, they minimize the viewer's volume for portability. This dynamic extension and retraction resolves the contradiction between protection and compactness.
4Object-affected harmful factors
If the viewer is made bulky to provide full coverage and protection, then lens protection and device security are improved, but portability and ease of carrying are reduced
Solution Approach 1:
The viewer transitions from a compact portable form when side bodies are folded to an extended protective form when side bodies are positioned outward. This dynamic transformation allows the viewer to provide full protection during use while remaining portable for carrying.
Solution Approach 2:
By separating the protective side bodies from the central holding body, the viewer can extend protection only where needed (at the lens edges) rather than requiring a uniformly bulky structure, thus improving portability while maintaining protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The viewer provides increased access to device ports, enhanced portability, and better lens protection by allowing the lenses to be exposed and protected as needed, addressing the limitations of existing designs.

AI summary
A virtual-reality or augmented-reality viewer (1) for a mobile electronic device (2), the viewer (1) including a central body (3), a left lens (4) and a right lens (4) arranged in the central body (3), a left side body (5) connected to the central body (3), a right side body (5) connected to the central body (3), and a tension mechanism (6) which biases the left and right side bodies (5) towards each other. In a first viewer state, a left portion of the central body (3) is accommodated in the left side body (5) and a right portion of the central body (3) is accommodated in the right side body (5). In a second viewer state, the left portion of the central body (3) is not accommodated in the left side body (5) and the right portion of the central body (3) is not accommodated in the right side body (5), so that the left and right lenses (4) are not covered by the left or right side body (5).
