Rotating Display Assembly for Head-Mounted Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted display devices, such as VR and AR devices, are inconvenient as they require users to remove the entire device for short breaks, and lack an unobtrusive design that allows easy switching between usage and non-usage states.
Innovation Solution
A head-mounted display device with a rotating assembly powered by a planetary gear reducer motor, allowing the display assembly to pivot between two positions, one directly in front of the user's field of vision and another angled 110 degrees away, enabling quick and easy toggling between usage and non-usage states without removing the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display assembly is made fixed and stable, then the device structure is simple and reliable, but the user cannot quickly switch between usage and non-usage states
Solution Approach 1:
The display assembly is transformed from a fixed structure to a dynamically adjustable one through the rotating assembly. The motor-driven rotation mechanism allows the display assembly to pivot between multiple positions, enabling quick transitions between usage and non-usage states while maintaining structural integrity through precision engineering of the rotating components
2Ease of operation
If the display assembly is positioned directly in front of the user, then the display is visible and usable, but the device becomes obtrusive and uncomfortable for extended wear
Solution Approach 1:
The rotating assembly enables the display assembly to be dynamically repositioned from a direct front position (visible and usable) to an angled or retracted position (less obtrusive). This dynamic adjustment allows users to switch between visibility and comfort based on their immediate needs, reducing the harmful effect of the device being constantly obtrusive
Solution Approach 2:
The device is segmented into fixed and rotating components, allowing the display assembly to be independently positioned. This segmentation enables the display to be moved out of the direct line of sight when not in use, reducing obtrusiveness while maintaining full functionality when needed
3Productivity
If the entire device must be removed for breaks, then the device structure is simple, but the user experiences loss of time and inconvenience
Solution Approach 1:
The rotating assembly provides dynamic repositioning capability that allows the display assembly to be quickly moved to a non-obtrusive position during breaks. This eliminates the need to remove the entire device, saving time and improving user convenience while maintaining a relatively simple overall device structure through modular design

AI summary
A head-mounted display device includes a display assembly, a rotating assembly, and a fixed assembly. The rotating assembly is connected to the display assembly and includes a motor holder, a motor and a first connecting element. The motor is disposed on the motor holder. The first connecting element has a first accommodating portion and a second accommodating portion, wherein the first connecting element receives a part of the motor and the second connecting element receives a part of the motor holder. The fixed assembly is connected to the rotating assembly. The rotating assembly rotates the display assembly relative to the fixed assembly.
