Adjustable Head-Mounted Display With Rotatable Ear Cups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted displays have fixed lengths for the head band and display legs, which limits their universality, and the sound outputting portion's components do not rotate, making storage inconvenient due to space inefficiency.
Innovation Solution
The adjustable head-mounted display features a head-mounted portion length adjustment mechanism, leg length adjustment mechanisms, and rotatable ear cup brackets, allowing for customizable fit and multidirectional rotation for efficient storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the head band and display legs have fixed lengths, then the structure is simple and easy to manufacture, but the universality is poor and cannot adapt to different head circumferences
Solution Approach 1:
The head band incorporates a length adjustment mechanism with a sliding rod that can move along the head band to change its effective length. The display legs also have adjustable lengths through a similar sliding mechanism, allowing the device to adapt to different user head circumferences while maintaining a relatively simple overall structure.
2Volume of stationary object
If the sound generators are fixedly connected to the head-mounted portion, then the structure is stable, but the storage space is large and inconvenient when traveling
Solution Approach 1:
The ear cup brackets are designed to be rotatable relative to the head-mounted portion, allowing the sound generators to be rotated into a compact position during storage. This dynamic adjustment enables the device to occupy less space in storage boxes while maintaining stable connection during use.
3Volume of stationary object
If the ear cup brackets are fixed and cannot rotate, then the structure is simple, but the storage efficiency is low and occupies large space
Solution Approach 1:
The ear cup brackets incorporate a rotation mechanism that allows them to rotate relative to the head-mounted portion. This dynamic feature enables compact storage configuration without requiring complex structures, as the rotation capability is integrated into the existing bracket design.

AI summary
An adjustable head-mounted display comprises a head-mounted portion (1), a display portion (2) and a sound outputting portion (3). The display portion (2) comprises two legs (21) and a display (22), one end of each leg (21) is connected to corresponding end of the display (22), and the other end of each leg (21) is rotatably connected to an end of the head-mounted portion (1) on corresponding side. The sound outputting portion (3) comprises a left headphone and a right headphone, wherein the left headphone and the right headphone each comprises an ear cup (32), an ear cup bracket and a sound generator in the ear cup. The ear cup bracket is connected to an end of the head-mounted portion (1) on corresponding side, and the ear cup is connected to the ear cup bracket; and the head-mounted portion (1) is provided with a head-mounted portion length adjustment mechanism. By the present disclosure, the user can adjust the length upon his demand, and the universality will be improved.
