Engineering Contradiction Analysis
1Ease of operation
If two-dimensional medical images are displayed on conventional display devices, then medical personnel can view medical images, but complex operations are required to obtain three-dimensional information and quick access to required information is hindered
Solution Approach 1:
The display device automatically senses viewer eye locations and determines ray casting paths without requiring manual intervention or complex operations from medical personnel. The system self-adjusts to provide three-dimensional display effects based on automatic eye tracking, eliminating the need for manual configuration while maintaining ease of obtaining three-dimensional information.
Solution Approach 2:
The patent replaces manual mechanical operations with automatic electronic sensing and calculation systems. Instead of requiring medical personnel to manually adjust or perform complex operations to obtain three-dimensional information, the system uses automatic eye coordinate sensing and ray path calculation to generate three-dimensional display effects, thereby reducing operational complexity.
2Extent of automation
If automatic eye location sensing and ray casting path calculation are implemented, then three-dimensional display effects are provided automatically, but device complexity increases
Solution Approach 1:
The display device integrates multiple functions including two-dimensional image display, eye location sensing, coordinate conversion, ray path calculation, and three-dimensional image rendering into a single unified system. This multi-functionality approach allows the device to provide automatic three-dimensional display effects while managing complexity through consolidation rather than adding separate independent systems.
