Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mountable display systems lack efficient integration of multiple display screens and securement mechanisms that provide comfortable fit and effective light blocking, while also accommodating user interaction and environmental illumination.
Innovation Solution
A head-mountable display device with a housing featuring dual display assemblies oriented in opposite directions, securement straps with electronic components, and a flexible textile material, along with a light seal to block external light, and adjustable mechanisms for positioning the display screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display screens are integrated in the head-mountable display device, then the display functionality and virtual reality experience are improved, but the device complexity increases
Solution Approach 1:
The display system is divided into multiple independent display assemblies, each with its own display screen positioned at different orientations. The first display assembly includes a first display screen, while the second display assembly includes a second display screen and a third display screen. This segmentation allows each display to function independently while contributing to the overall virtual reality experience, resolving the contradiction between enhanced display functionality and reduced device complexity.
Solution Approach 2:
The display screens are arranged in different spatial dimensions and orientations rather than a single plane. The first display screen is oriented to project light in a first direction, while the second and third display screens are oriented to direct light in a second direction opposite the first direction. This three-dimensional arrangement increases display versatility without proportionally increasing perceived device complexity.
2Ease of operation
If securement straps with electronic components are added to provide a secure fit, then user comfort and stability are improved, but the device complexity increases
Solution Approach 1:
The securement straps are integrated with electronic components to form unified functional elements. The first securement strap includes a first electronic component, and the second securement strap includes a second electronic component. This merging combines the mechanical function of securing the device to the user's head with electronic functionality, improving user comfort and stability while minimizing the increase in device complexity through integration rather than addition.
3Object-affected harmful factors
If a light seal is added to block external light, then light blocking effectiveness is improved, but the device complexity increases
Solution Approach 1:
The light seal is constructed from flexible material that can conform to the user's facial contours. This flexible shell approach provides effective light blocking by creating a seal around the user's eyes while maintaining comfort and ease of wear. The flexibility allows the light seal to adapt to different users without requiring complex adjustable mechanisms, thus improving light blocking effectiveness with minimal increase in device complexity.
4Adaptability or versatility
If display screens are oriented in opposite directions to project light in different directions, then the versatility of the display system is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The display system is segmented into separate display assemblies, each with independently oriented display screens. The first display assembly and second display assembly are positioned and oriented independently, allowing each to be manufactured and assembled with standard precision tolerances. This segmentation distributes the manufacturing complexity across separate components rather than requiring high precision in a single integrated structure.
Solution Approach 2:
The display assemblies are designed with adjustable positioning capabilities, allowing the display screens to be oriented in different directions (first direction and second direction opposite to the first). This dynamic adjustability compensates for manufacturing variations and allows the system to achieve the required optical precision through post-manufacturing adjustment rather than requiring extremely tight manufacturing tolerances.
