Head-Mountable Display Straps for Adaptive Fit and Light Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head mountable computer systems for augmented and virtual reality struggle with providing comfortable and effective display solutions that securely fit various user head shapes and sizes, while also ensuring proper light sealing and integration of electronic components.
Innovation Solution
The development of a head-mountable display device featuring a housing with a front and rear opening, a display screen in the front opening, a display assembly in the rear opening, and securement straps with electronic components, along with a flexible textile securement band that follows the contours of a user's face for improved fit and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rigid head mountable displays are used, then structural stability is maintained, but user comfort and adaptability to various head shapes deteriorates
Solution Approach 1:
The securement system is divided into multiple independent components: a head strap with first and second portions, a bridge component connecting the portions, and adjustable fastening mechanisms. This segmentation allows each component to be optimized independently for comfort and adjustability while maintaining overall structural integrity.
Solution Approach 2:
The bridge component is designed to be movable relative to the head strap portions, allowing dynamic adjustment of the display device's position and orientation. This movable connection enables the system to adapt to various head shapes and user preferences without requiring a completely rigid structure.
2Object-affected harmful factors
If display components are integrated into the housing, then light sealing is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The display device is segmented into distinct modules: housing, display assembly, securement system, and optical components. Each module can be manufactured and tested separately before final assembly, reducing manufacturing complexity while enabling precise integration of light-sealing features at the interfaces between modules.
Solution Approach 2:
Interface components and sealing elements act as intermediaries between the housing and display assembly, ensuring proper light sealing without requiring complex integrated structures. These intermediary elements simplify the assembly process while effectively preventing light leakage.
3Adaptability or versatility
If securement straps with electronic components are added, then functionality is enhanced, but device complexity and weight increase
Solution Approach 1:
Electronic components such as speakers and computing components are merged with the securement straps and housing structures. This integration allows multiple functions to be combined into single components, reducing the total number of separate parts and minimizing overall weight while enhancing functionality.
Solution Approach 2:
The securement straps and housing structures serve multiple functions: they provide mechanical support, enable adjustment, integrate electronic components like speakers and computing components, and maintain light sealing. This multi-functionality reduces the need for additional dedicated components, thereby minimizing weight increase.
