HMD Foam Support Adjustment for Eye Relief and Wearing Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display apparatuses lack the ability to adjust eye relief and wearing angle to meet individual user needs, resulting in poor fit and user experience.
Innovation Solution
An adjusting mechanism comprising a sliding module and a flipping module that allow for adjustable eye relief and wearing angle by changing the horizontal distance and rotational position of the foam support relative to the middle shell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the foam bracket and middle shell are fixed as a whole structure, then the manufacturing precision and structural stability are improved, but the adaptability for different users' eye relief and wearing angle needs deteriorates
Solution Approach 1:
The foam bracket assembly is divided into multiple independent modules: a sliding module that adjusts horizontal distance (eye relief) and a flipping module that adjusts the wearing angle. Each module can be independently adjusted to suit different user needs while maintaining overall structural integrity.
Solution Approach 2:
The fixed structure is transformed into a dynamic adjustable structure. The sliding module enables horizontal movement to change eye relief distance, while the flipping module enables rotational movement to change wearing angle, allowing the device to adapt to different users dynamically.
2Device complexity
If the eye relief and wearing angle are fixed, then the device complexity is reduced, but the ease of operation for personalized adjustment deteriorates
Solution Approach 1:
The adjustment function is segmented into two independent modules: sliding module for eye relief adjustment and flipping module for wearing angle adjustment. This segmentation allows each module to have a simple, dedicated adjustment mechanism rather than a complex integrated system.
Solution Approach 2:
The device enables users to perform self-adjustment of eye relief and wearing angle according to their own needs. The sliding and flipping modules are designed to be user-operable without requiring professional assistance, allowing personalized fit adjustment.

AI summary
An adjusting mechanism is disclosed. The adjusting mechanism includes, but is not limited to, a middle shell and a foam support. The adjusting mechanism further includes, but is not limited to a sliding module movably arranged in the middle shell, connected with the foam support, and configured to adjust a horizontal spacing between the middle shell and the foam support. The adjusting mechanism still further includes, but is not limited to, a flipping module rotatably arranged on the sliding module, connected with the foam support, and configured to drive the foam support to flip relative to the middle shell.
