Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques are unable to display information in regions larger than the normal visual field and enable visual recognition of such information.
Innovation Solution
A display device with a light irradiation system that applies light on regions outside the ambient light irradiation region, including a contact or intraocular lens type display element with pixels arranged two- or three-dimensionally, capable of projecting light onto the retina beyond the normal visual field limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If light is applied only on the ambient light irradiation region through the pupil, then the display device can maintain normal visual field coverage, but it cannot display information in regions larger than the visual field region
Solution Approach 1:
The patent applies light not only through the pupil (central dimension) but also on regions outside the ambient light irradiation region (peripheral dimension), effectively expanding the visual field coverage from the central visual axis to include peripheral retinal regions, thereby displaying information in a larger region than the normal visual field
Solution Approach 2:
The patent divides the light irradiation into multiple regions: the ambient light irradiation region through the pupil and additional regions outside this area. By segmenting the irradiation zones and applying light selectively to different retinal regions, the system expands visual field coverage while maintaining normal central vision
2Area of stationary object
If a display element is integrated with the eyeball to expand visual field coverage, then information can be displayed in a larger region, but the device complexity increases
Solution Approach 1:
The display element is integrated within the eyeball structure itself, nesting the display functionality inside the existing ocular anatomy. This approach expands visual field coverage while minimizing external device complexity by utilizing the eye's own structure as the mounting platform
Solution Approach 2:
The integrated display element serves multiple functions: it displays information in expanded visual field regions while coexisting with the natural visual pathway. The system achieves both normal vision through the pupil and enhanced peripheral information display through the same integrated structure
