Head-Mounted Display Adjustment Mechanism for Linear and Angular Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mountable devices (HMDs) lack customizable adjustment mechanisms to accommodate users with different facial features and eyesight needs, leading to uncomfortable and suboptimal viewing experiences.
Innovation Solution
The HMDs incorporate a connection between the display and facial interface that allows for translational and rotational adjustments, featuring actuators like levers, buttons, or sliders for intuitive control, enabling angular and linear adjustments to fit various users comfortably.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional HMDs use fixed display positioning, then device structure is simple, but user comfort and viewing quality deteriorate due to inability to accommodate different facial features
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed display positioning into a dynamic, adjustable system. The display assembly is made movable relative to the facial interface through adjustment mechanisms that allow linear translation and angular rotation, enabling the system to adapt to different user facial features while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements parameter changes by providing adjustment mechanisms that modify key geometric parameters - specifically the linear distance between display and facial interface, and the angular orientation of the display. These parameter adjustments allow optimization of viewing comfort for different users without fundamentally redesigning the entire device structure.
2Adaptability or versatility
If HMDs lack customization capabilities, then manufacturing is simpler, but adaptability to different users deteriorates
Solution Approach 1:
The patent applies universality by designing adjustment mechanisms that enable a single HMD device to accommodate multiple users with different facial features and eyesight needs. The movable display assembly with adjustment capabilities allows one device to serve multiple purposes across different users, eliminating the need for custom-manufactured devices for each user while maintaining high adaptability.
3Manufacturing precision
If display position is fixed relative to facial interface, then connection structure is simpler, but viewing quality and eye relief deteriorate
Solution Approach 1:
The patent applies dynamics to the connection structure by transitioning from a fixed rigid connection to a dynamic adjustable connection. The display assembly can translate linearly and rotate angularly relative to the facial interface through the connection mechanism, enabling precise positioning optimization for different users while maintaining structural integrity.
Solution Approach 2:
The patent implements segmentation by dividing the connection into functional segments - a movable display assembly and a facial interface - connected through adjustment mechanisms. This segmentation allows independent optimization of each component while providing adjustability, achieving high viewing quality without requiring complete redesign of the entire connection structure.
