Head-Mounted Display Adjustable Fixing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted display devices are difficult for users to adjust and wear comfortably, leading to a negative impact on user experience due to their inflexible design, which does not accommodate varying head shapes effectively.
Innovation Solution
A head-mounted display device featuring an adjustable fixing assembly that can expand to fit larger head shapes and contract to securely fit around the user's head, incorporating sliding and rotating mechanisms, as well as elastic cover members, to distribute pressure across multiple contact points, enhancing comfort and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an integrated mask or pad is used for head-mounted display devices, then the device structure is simple, but it is difficult for users to adjust and wear comfortably
Solution Approach 1:
The device is divided into multiple independent components: a front element, extending portions, and adjustable fixing assemblies. Each fixing assembly can be independently adjusted to accommodate different head shapes and sizes, providing customization without requiring complete structural redesign.
Solution Approach 2:
The fixing assemblies incorporate sliding mechanisms that allow dynamic adjustment of the device's fit to the user's head. The sliding portions enable the fixing assemblies to move along the extending portions, adapting to different head circumferences and shapes while maintaining a secure fit.
2Adaptability or versatility
If the device is designed to fit one head shape, then the device structure is simple, but it cannot accommodate varying head shapes effectively
Solution Approach 1:
The adjustable fixing assemblies serve multiple functions: they secure the device to the head, accommodate different head shapes, and provide pressure distribution. The same structural components enable adaptation to various head sizes and shapes through sliding adjustments, eliminating the need for multiple device variants.
Solution Approach 2:
The device allows adjustment of key dimensional parameters through sliding mechanisms. The distance between the front element and the rear fixing points can be modified by sliding the fixing assemblies along the extending portions, enabling adaptation to different head circumferences and shapes while maintaining structural integrity.
3Reliability
If the fixing assembly is made rigid for secure fit, then the device stability is high, but the user experience is negative due to discomfort
Solution Approach 1:
The fixing assemblies combine rigid structural elements with sliding adjustment mechanisms. The rigid portions provide stable securing force, while the sliding portions enable dynamic adjustment to achieve optimal fit and comfort for different users, transforming a static rigid structure into an adaptively stable system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a secure and comfortable fit for users with different head shapes by easily adjusting to accommodate various sizes, preventing the device from falling off and improving overall user experience through distributed pressure and increased contact points.

AI summary
A head-mounted display device including a front element, a pair of extending portions, an adjustable fixing assembly, a top adjustable fixing assembly, a rear adjustable fixing assembly, and a rotatable adjusting mechanism is provided. The front element is adapted to be placed or be installed with a display device and is adapted to cover eyes of a user. The top adjustable fixing assembly is adapted to be in contact with a parietal bone of the user. The rear adjustable fixing assembly is adapted to be in contact with an occipital bone of the user. The adjustable fixing assembly and the top adjustable fixing assembly are adjustable according to head shapes of different users. The rotatable adjusting mechanism adjusts the rear adjustable fixing assembly so that the rear adjustable fixing assembly is adapted to head shapes of different users.
