Head-Mountable Display Securement and Light Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mountable display systems face challenges in providing comfortable and effective virtual and mixed reality experiences due to limitations in design, including inadequate securement mechanisms and light sealing, which affect user comfort and immersion.
Innovation Solution
The design incorporates a head-mountable display device with a housing featuring a front and rear opening, a display screen, and securement straps with electronic components, including a speaker and computing unit, along with a flexible textile securement band that follows the user's face contours, and an adjustment mechanism for optimal positioning, and a light seal to block external light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional securement mechanisms are used in head-mountable displays, then the device structure is simple, but user comfort and stability are insufficient
Solution Approach 1:
The securement system is divided into multiple independent components: a head strap with first and second portions, adjustable buckles, and a forehead band. This segmentation allows each component to be optimized independently for comfort and adjustability while maintaining overall system functionality.
Solution Approach 2:
The securement mechanism incorporates adjustable elements including movable buckles and elastic forehead bands that can dynamically adapt to different user head shapes and sizes. The system transitions from a static design to a dynamic one that can be reconfigured for optimal comfort.
2Object-affected harmful factors
If basic light sealing is implemented, then the device structure is simple, but light blocking performance is inadequate
Solution Approach 1:
The light seal utilizes flexible black rubber material that forms a continuous barrier around the display assembly. This flexible film conforms to the contours of the display housing while maintaining effective light blocking, combining simplicity with functional effectiveness.
3Adaptability or versatility
If fixed display positioning is used, then the device structure is simple, but adaptability to different users is limited
Solution Approach 1:
The display assembly incorporates movable mounting mechanisms that allow it to be repositioned along the head strap and adjusted for different user preferences. The display can be moved forward, backward, and laterally within defined ranges, providing adaptability without requiring a completely complex reconfiguration system.
