Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an iris acquisition function is added to the virtual reality device, then user security and privacy are enhanced, but device complexity increases
Solution Approach 1:
The patent combines the iris acquisition function with the existing virtual reality device structure by integrating an iris camera and infrared source into the housing. The iris camera is positioned to capture iris images through the displaying surface without requiring separate security devices, thereby enhancing user security while minimizing additional complexity.
Solution Approach 2:
The virtual reality device is designed to perform multiple functions: displaying virtual reality content and acquiring iris images for biometric authentication. The housing and optical components serve dual purposes, allowing the device to function as both a VR display and a security authentication system.
2Adaptability or versatility
If an iris camera and infrared source are integrated into the virtual reality device, then biometric authentication capability is provided, but the line of sight and display screen may be interfered with
Solution Approach 1:
The iris camera and infrared source are positioned at specific locations within the housing that are optimized for iris capture while minimizing interference with the user's line of sight and display viewing. The infrared source is placed to illuminate the iris without creating visible distractions, and the iris camera is positioned to capture images through specific regions of the displaying surface.
Solution Approach 2:
The displaying surface acts as an intermediary through which the iris camera captures iris images. The infrared source illuminates the iris, and the light reflects through the displaying surface to the iris camera, allowing biometric authentication without direct line-of-sight obstruction for the user.
3Measurement precision
If the infrared source is positioned to illuminate the iris, then iris image capture is improved, but the positioning requirements become more complex
Solution Approach 1:
The infrared source is pre-positioned within the housing at a location that optimally illuminates the user's iris when the virtual reality device is worn. The iris camera is similarly pre-positioned to capture reflected infrared light from the iris through the displaying surface, eliminating the need for real-time positioning adjustments.

AI summary
A virtual reality device with iris acquisition function, includes a housing having an accommodating space, an observing lens embedded in the housing, a display screen accommodated in the housing and arranged opposite to the observing lens, and at least one iris camera accommodated in the housing. The virtual reality device further includes at least one infrared source accommodated in the housing, the infrared source is arranged on a focal plane of the observing lens and light emitted from the infrared source passes through the observing lens to an iris of a human eye. The iris camera is configured to acquire an iris image of a human eye through the observing lens and the iris camera is arranged at a position which will not interfere a line of sight of the human eye on the infrared source and the display screen.
