Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable display devices face challenges in achieving high resolution while minimizing size, weight, and cost, as increased resolution leads to larger and heavier devices, making them inconvenient for users and less appealing to consumers.
Innovation Solution
The integration of an image beam shifter and a light guiding component allows for the projection of image beams to different positions either simultaneously or with time division, effectively reducing the display area and thus the size and weight of the device, while maintaining or enhancing resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of the display screen is increased, then the display quality is improved, but the size and weight of the display device are increased
Solution Approach 1:
The patent divides the display system into multiple components: a display screen, an image beam shifter, and a light guiding component. The image beam shifter segments the image beam into multiple projected image beams that are directed to different positions, allowing high-resolution display without requiring a proportionally large display screen area.
Solution Approach 2:
The patent transitions from a two-dimensional display approach to a three-dimensional optical path approach. By using the light guiding component to transport projected image beams to different positions in space and the image beam shifter to project beams to different positions on the light guiding component, the system achieves high resolution by utilizing spatial dimensionality rather than simply increasing display screen area.
2Measurement precision
If the resolution of the display screen is increased, then the display quality is improved, but the size of the display device is increased
Solution Approach 1:
The patent segments the image beam into multiple projected image beams through the image beam shifter, which then directs these beams to different positions on the light guiding component. This segmentation allows the system to achieve high resolution by distributing image information across multiple spatial positions rather than requiring a single large display area.
Solution Approach 2:
The light guiding component serves as an intermediary between the display screen and the target display positions. It receives projected image beams from the image beam shifter and transports them to different positions in the target zone, enabling compact device design while achieving high-resolution display across multiple positions.
3Measurement precision
If the size and weight of the display device are increased, then the display resolution can be improved, but the user convenience is reduced
Solution Approach 1:
The patent employs dynamic beam shifting through the image beam shifter, which can project image beams to different positions on the light guiding component with time division. This dynamic capability allows the system to achieve high resolution without requiring a large, static display structure, thereby maintaining portability and user convenience.
Solution Approach 2:
The patent replaces traditional mechanical display expansion with an optical system. Instead of physically enlarging the display screen to achieve higher resolution, the system uses optical beam shifting and light guiding to project high-resolution images to multiple positions, eliminating the need for increased device size and weight.
4Area of stationary object
If the display area is reduced, then the device size and weight are reduced, but the display resolution may be compromised
Solution Approach 1:
The patent compensates for reduced display area by utilizing the third dimension (spatial positioning). The light guiding component transports projected image beams to different positions in the target zone, and the image beam shifter projects beams to different positions on the light guiding component, effectively distributing high-resolution display across multiple spatial locations rather than requiring a single large area.
Solution Approach 2:
The patent changes the parameter of image beam positioning by using the image beam shifter to dynamically adjust where image beams are projected on the light guiding component. This parameter change allows the system to achieve high resolution by varying beam positions over time and space rather than relying on a large static display area.
