Head-Mounted Display Rotating Extension Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display devices experience instability and discomfort due to uneven weight distribution and complex fixing mechanisms, leading to difficulty in wearing and removing them.
Innovation Solution
The use of two extension members that can rotate to contact or depart from the sides of the head, combined with an adjustable fixing member, allows for a secure and comfortable fit, improving wearability and convenience by allowing easy adjustment and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a complex fixing mechanism is used to secure the head-mounted display device, then the stability is improved, but the ease of operation deteriorates
Solution Approach 1:
The fixing mechanism is divided into two independent extension members (first and second extension members) that can be adjusted separately. Each extension member has its own adjusting mechanism, allowing the user to independently adjust the fit on each side of the head, simplifying the overall operation while maintaining stability
Solution Approach 2:
The extension members are designed to be adjustable rather than fixed. The adjusting mechanisms allow the extension members to be dynamically modified in length or position, enabling the device to adapt to different head sizes and shapes, thereby improving both stability and ease of operation
2Stability of the object's composition
If the fixing structure is made more complex to improve stability, then the stability is improved, but the device complexity increases
Solution Approach 1:
The fixing structure is segmented into two separate extension members with independent adjusting mechanisms. This segmentation reduces the complexity of any single component while maintaining overall system stability through the combined effect of both members working together
Solution Approach 2:
The extension members serve multiple functions: they provide structural support for stability, allow for adjustment to fit different users, and can be independently modified. This multi-functionality reduces the need for additional specialized components, thereby reducing overall device complexity
3Stability of the object's composition
If the head-mounted display device is made to fit tightly, then the stability is improved, but the comfort deteriorates due to pressure on specific parts
Solution Approach 1:
The adjusting mechanisms allow for localized adjustment of the extension members. Users can independently modify the fit at different locations on their head, distributing the pressure more evenly and avoiding concentration of force on sensitive areas like the ears, thereby maintaining stability while improving comfort
Solution Approach 2:
The adjustable extension members enable dynamic modification of the device's fit characteristics. Users can adjust the tension and position to achieve a secure fit without excessive pressure, allowing the device to adapt to the user's head shape and comfort preferences
4Ease of operation
If the extension members are made adjustable to improve comfort, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The adjusting mechanism is segmented into simple, independent components for each extension member. This segmentation allows for easy adjustment without requiring complex coordinated mechanisms, improving ease of operation while keeping the overall device complexity manageable through modular design

AI summary
A head-mounted display device includes a body, two extension members and an adjustable fixing member. The body is adapted to lean against a front portion of a head of the user. The two extension members are disposed opposite each other. First ends of the two extension members are respectively coupled to two opposite ends of the body and configured to rotate with respect to the body so as to lean against two side portions of the head. The adjustable fixing member is coupled to each second end of the two extension members to lean against the back portion or top portion of the head, wherein the body is fixed on the head through the two extension members and the adjustable fixing member. Each of the extension members is adapted to contact or to depart from the two side portions of the head by rotating with respect to the body.
