Head-Mounted Display Holding Element for Secure Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display (HMD) apparatuses tend to slip down due to the weight of the image module, causing discomfort and headaches, and existing solutions like holding bands can be intrusive and uncomfortable.
Innovation Solution
The display apparatus features a shiftably mounted holding element on the temples with a unique internal surface curvature and a locking mechanism, allowing individual positioning behind the ear for secure and comfortable fit, preventing forward sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a holding band is provided to prevent the HMD from slipping down, then the stability of the HMD is improved, but the comfort of the user deteriorates due to pressure on the nose and head
Solution Approach 1:
The invention extracts the holding function from the nose support region and relocates it to the temples and behind the ears. The holding elements are mounted on the temples and extend backward to engage with the temporal bone region, removing the need for a holding band that presses on the nose and head.
Solution Approach 2:
The holding elements act as intermediaries between the HMD frame and the user's head. Instead of directly pressing on the nose, the holding elements engage with the temporal bone region behind the ears, using the temple structure as a mediator to distribute and redirect the holding force away from sensitive areas.
2Stability of the object's composition
If the holding element is made rigid to provide stable support, then the stability of the HMD is improved, but the adaptability to different user head shapes deteriorates
Solution Approach 1:
The holding element incorporates a pivot connection that allows it to rotate and adjust its angle relative to the temple. This dynamic adjustment capability enables the holding element to adapt to different head shapes and anatomical variations while maintaining stable support. The pivot connection allows the holding element to find its optimal engagement position with the temporal bone region.
3Stability of the object's composition
If the holding element extends far downwards to increase abutment area, then the stability of the HMD is improved, but the compactness of the apparatus deteriorates
Solution Approach 1:
Instead of extending the holding element primarily in the downward direction, the invention utilizes the longitudinal dimension of the temple. The holding element extends backward along the temple toward the temporal bone region, achieving stable engagement through longitudinal positioning rather than excessive downward extension. This dimensional shift maintains compactness while providing sufficient abutment area.

AI summary
A display apparatus which comprises an image module for generating an image, a spectacle-like frame which carries the image module, and wherein the spectacle-like frame comprises a front portion with a nose support, as well as two lateral temples mounted to the front portion. At least one of the temples has shiftably mounted to it a holding element. The holding element comprises a first portion extending downwards from the temple, and a second portion connected with the lower end of the first portion, the second portion extending from the lower end of the first portion in a direction pointing away from the front portion.
