Pivoting Head Abutting Portion for HMD Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays (HMDs) often fail to provide optimal comfort for users due to inadequate design, leading to discomfort during extended use in virtual reality environments.
Innovation Solution
A head-mounted display design featuring a pivotally connected head abutting portion with a rotating mechanism and annular soft pads, allowing for adjustable angle alignment with the user's head and improved contact distribution, enhancing comfort through a combination of rotating rods, pivoting portions, and a connecting belt for structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the head abutting portion is rigidly connected to the connecting structure, then the structural stability is improved, but the wearing comfort deteriorates due to inability to adapt to user's head position
Solution Approach 1:
The head abutting portion is pivotally connected to the connecting structure, allowing it to rotate relative to the connecting structure. This dynamic connection enables the head abutting portion to adapt to different user head positions and angles while maintaining structural stability through the pivot connection mechanism.
2Ease of operation
If the head abutting portion is pivotally connected to allow rotation, then the wearing comfort is improved, but the device complexity increases due to additional pivoting mechanism
Solution Approach 1:
The pivotal connection between the head abutting portion and connecting structure provides rotational freedom to adapt to user comfort needs. The pivot mechanism includes a pivot axis and pivot connection structure that enables controlled rotation while adding minimal complexity to the overall device.
3Ease of operation
If soft pads are added to increase contact area, then the wearing comfort is improved, but the device complexity increases due to additional components
Solution Approach 1:
Soft pads are strategically positioned at specific contact points between the head abutting portion and the user's head. The first soft pad is located on the inner surface of the head abutting portion, and the second soft pad is positioned to enhance contact comfort, providing localized comfort improvement without requiring complete soft padding throughout the entire structure.

AI summary
A head-mounted display includes a display device, a connecting structure and a head abutting portion. The connecting structure is in a shape of strip. The connecting structure has two opposite ends. The ends are respectively connected with the display device. The connecting structure and the display device define an accommodation space. The accommodation space is configured to accommodate a head of a user. The head abutting portion is pivotally connected with the connecting structure. The head abutting portion is at least partially located between the connecting structure and the display device. The head abutting portion is configured to abut against the head of the user.
