Dual Mode Headset Pivot Frame AR VR Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current AR and VR headsets are expensive, complex, and designed for only one type of user experience, requiring separate units for dynamic or static experiences, limiting user flexibility and developer innovation due to their large and heavy designs.
Innovation Solution
A dual-mode headset with a pivot frame and reflective screen that allows for both augmented reality (AR) and virtual reality (VR) modes by pivoting between positions, using a holder for electronic devices with a reflective screen to reflect content and accommodate corrective optics for focused viewing in VR mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a headset is designed for VR mode with shut-out surroundings, then immersive static experience is improved, but adaptability for AR mode is worsened
Solution Approach 1:
The patent implements a pivot frame that can rotate between VR and AR positions, allowing the headset to dynamically change its configuration. The display assembly can pivot to different angles, enabling the same hardware to serve both VR (shut-out) and AR (transparent) modes, thus resolving the contradiction between mode adaptability and device complexity.
Solution Approach 2:
The headset is designed with universal components that serve multiple functions. The same display assembly, when positioned at different angles via the pivot frame, provides both VR and AR experiences. This multi-functionality eliminates the need for separate dedicated VR and AR headsets, improving adaptability without proportionally increasing complexity.
2Reliability
If separate VR and AR headsets are manufactured, then specialized performance is improved, but manufacturing cost is worsened
Solution Approach 1:
The patent creates a universal headset platform that can deliver both VR and AR performance through a single device. By using a pivot frame mechanism that allows the display assembly to switch between positions, the same manufacturing base serves both modes, reducing the need for separate production lines and lowering overall manufacturing costs while maintaining specialized performance for each mode.
Solution Approach 2:
The invention merges VR and AR functionalities into a single headset unit. The pivot frame mechanism combines the optical paths for both modes within one device, allowing manufacturers to produce one type of headset rather than two separate specialized units, thereby reducing manufacturing costs while preserving mode-specific performance.
3Manufacturing precision
If headset components are made large for VR immersion, then VR display quality is improved, but portability is worsened
Solution Approach 1:
The pivot frame mechanism allows the display assembly to be positioned dynamically. In VR mode, the display can be positioned closer to the eye for immersive quality, while in AR mode, it can be positioned further away or at an angle that reduces the perceived bulk and weight. This dynamic positioning optimizes display quality when needed while improving portability and comfort during extended wear.
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
Enables a single headset to seamlessly switch between AR and VR modes, providing users with flexibility and developers with reduced hardware investment, while maintaining clear visibility of surroundings in AR mode and focused display in VR mode.
Implementation Method 1
a reflective screen (8) configured to reflect content displayed on the display screen (7)
Implementation Method 2
a pivot frame (4) rotatable between a first pivot frame position in which the holder (5) and the reflective screen (8) are in the AR position and a second pivot frame position in which the holder (5) and the reflective screen (8) are in the VR position

AI summary
A dual mode VR and AR headset (1) comprising head-attachment means (2), a main frame (3) connected to said head-attachment means (2), and a pivot frame (4). The pivot frame (4) comprises a holder (5) configured to accommodate an electronic device (6) having a display screen (7), and a reflective screen (8) configured to reflect content shown on said display screen (7). The pivot frame (4) is pivotally connected to the main frame (3), allowing the pivot frame (4) to be moved between a first pivot frame position and a second pivot frame position relative to the main frame. In the first pivot frame position, the reflective screen (8) at least partially intersects a field of view (α) of a user wearing the headset (1), and in the second pivot frame position, and when the electronic device (6) is accommodated in the holder (5), the display screen (7) at least partially intersects the field of view (α).
