Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single display assembly is used in traditional head-mountable devices, then the device structure remains simple, but light projection efficiency and user comfort are limited
Solution Approach 1:
The display system is divided into multiple independent display assemblies (first display assembly with first display screen, second display assembly with second and third display screens) that can be positioned separately. Each display assembly can be independently oriented and positioned to optimize light projection toward different regions of the user's face, thereby improving overall light projection efficiency while maintaining manageable system complexity through modular segmentation.
Solution Approach 2:
The patent transitions from a single display orientation to multiple display orientations by positioning display screens at different angles and directions. The first display screen projects light in a first direction while the second display screen and third display screen project light in a second direction opposite the first direction, utilizing spatial dimensionality to enhance coverage and efficiency.
2Adaptability or versatility
If fixed positioning mechanisms are used for display assemblies, then device structure remains simple, but user comfort and adaptability are reduced
Solution Approach 1:
The patent implements adjustable positioning mechanisms that allow the display assemblies to be dynamically repositioned. The first display assembly and second display assembly can be adjusted to different positions and orientations, enabling adaptation to different users and usage scenarios. This dynamic adjustability improves user comfort and versatility while the mechanisms remain integrated into the overall device structure.
3Extent of automation
If traditional securement straps without electronic components are used, then the device remains simple, but functionality and user experience are limited
Solution Approach 1:
The patent merges electronic components directly into the securement straps. The first securement strap includes a first electronic component and the second securement strap includes a second electronic component, combining the functions of securing the device to the user's head with additional electronic functionalities such as sensors, actuators, or communication modules. This integration enhances user experience and enables automated features while the straps remain part of the overall device structure.
4Object-affected harmful factors
If insufficient light blocking is provided, then the device structure remains simple, but user comfort and immersion are reduced
Solution Approach 1:
The patent employs flexible light sealing structures, including flexible light seal materials that can conform to the user's face contours. These flexible seals create effective light blocking around the display assemblies and viewing zones, preventing external light interference and enhancing user comfort and immersion. The flexible nature of these seals allows them to adapt to different users while maintaining effective light blocking.
