Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head mountable display systems for augmented and virtual reality lack effective securement mechanisms and light sealing solutions that provide both comfort and optimal visual experience, particularly in terms of adjustable display positioning and effective light blocking.
Innovation Solution
A head-mountable display device featuring a housing with securement straps and a flexible textile band, a display assembly with adjustable position mechanisms, and a light seal that presses against the user's face to block external light, ensuring comfortable fit and clear visuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If securement straps are added to the head mountable display device, then the device can be securely fastened to the user's head, but the device complexity increases
Solution Approach 1:
The securement system is divided into separate components: a first securement strap with a first electronic component, a second securement strap with a second electronic component, and a securement band connecting them. This segmentation allows each component to perform its specific function while distributing the overall complexity across multiple simpler elements rather than a single complex mechanism.
Solution Approach 2:
The securement straps and band serve multiple functions: they provide mechanical securement to hold the display device to the user's head, and the integrated electronic components enable tracking and monitoring of securement status, wearability, and user interaction. This multi-functionality reduces the need for separate systems.
2Object-affected harmful factors
If a light seal is added to block external light, then the visual experience is enhanced, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The light seal is implemented as a flexible component that can be integrated into the housing structure. This flexible approach allows the seal to conform to the housing geometry and provide effective light blocking without requiring complex rigid mechanisms or multiple assembly steps, thereby reducing overall device complexity.
3Ease of operation
If the display assembly position is made adjustable, then the comfort and visual quality improve, but the device complexity and manufacturing precision requirements increase
Solution Approach 1:
The display assembly position is made adjustable through an adjustment mechanism that allows the display to move between multiple positions. This dynamic capability enables the system to adapt to different user needs and preferences. The mechanism is designed to provide discrete, pre-determined positions that balance adjustability with manufacturing precision requirements.
4Adaptability or versatility
If multiple display assemblies are included, then the versatility and visual experience improve, but the device complexity and volume increase
Solution Approach 1:
Multiple display assemblies are integrated within the housing structure in a nested arrangement, where the displays are positioned within the internal volume of the device. This nesting approach allows multiple display units to be compactly arranged without proportionally increasing the external dimensions or overall complexity of the device, as the displays share the internal space efficiently.
