Head-Mounted Display Weight Distribution via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display devices often cause discomfort such as headaches and neck pain due to suboptimal weight distribution between the front and back, which is not adequately addressed in existing designs for surgical or scientific imaging applications.
Innovation Solution
The design splits the functionality into a display assembly at the front and a video processing assembly at the back, with a main mounting structure that balances the weight and positioning to place the center of gravity above the spine, ensuring equal weight distribution between the front and back, thereby reducing discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display assembly and video processing assembly are placed together at the front of the head-mounted display device, then the device structure is simplified, but the weight distribution becomes unbalanced causing user discomfort
Solution Approach 1:
The device is divided into two separate assemblies: a display assembly containing the display device and optical elements, and a video processing assembly containing the processing circuitry. These assemblies are positioned at different locations on the head-mounted display device to achieve balanced weight distribution, resolving the contradiction between structural simplicity and user comfort.
2Manufacturing precision
If the display assembly is made heavier to improve display quality, then the display performance is improved, but the weight distribution becomes unbalanced causing strain on the user's head and neck
Solution Approach 1:
The video processing assembly is positioned on the opposite side of the head-mounted display device from the display assembly to act as a counterweight. This balances the weight distribution caused by the heavier display assembly, preventing strain on the user's head and neck while maintaining high display quality.
3Device complexity
If the video processing assembly is placed at the front with the display assembly, then the device structure is simplified, but the center of gravity shifts forward causing neck pain and headaches
Solution Approach 1:
Instead of placing the video processing assembly at the front with the display assembly, the invention inverts this arrangement by positioning the video processing assembly at the back of the head-mounted display device. This reverses the weight distribution pattern and shifts the center of gravity to a more balanced position, eliminating headaches and neck pain.

AI summary
Examples relate to a head-mounted display device, a method for providing a head-mounted display device and a scientific or surgical imaging system comprising a head-mounted display device. The head-mounted display device comprises a display assembly, comprising one or more displays for displaying the image. The head-mounted display device comprises a video processing assembly, comprising processing circuitry for generating at least one processed display signal for the one or more displays based on an input display signal. The head-mounted display device comprises a main mounting structure for fastening the display assembly and the video processing assembly to the head of a user. At least one of a weight of the display assembly and the video processing assembly and a positioning of the display assembly and the video processing assembly at the main mounting structure is such, that a weight distribution between front and back of the head-mounted display device is balanced.
