Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional stereo display technology is used, then stereo image display function is achieved, but user comfort and convenience deteriorate due to requiring special glasses
Solution Approach 1:
The patent extracts and eliminates the special glasses component from the stereo display system. By using a curved-surface imaging element that inherently provides stereo image separation, the system removes the need for users to wear additional eyewear, thereby improving comfort and convenience while maintaining the stereo display function.
Solution Approach 2:
The curved-surface imaging element serves multiple functions: it displays stereo images, separates left-eye and right-eye images, and eliminates the need for separate glasses. This multi-functional approach resolves the contradiction by integrating the stereo separation function directly into the display hardware.
2Reliability
If special glasses are required for stereo display, then stereo image separation is achieved, but device complexity and inconvenience increase
Solution Approach 1:
The patent removes the external glasses component and integrates the image separation function directly into the curved-surface imaging element, reducing system complexity while maintaining reliable stereo image separation through the inherent optical properties of the curved surface.
Solution Approach 2:
The curved-surface imaging element uses its spherical curvature to inherently separate and direct left-eye and right-eye images to different regions of the user's field of view. This geometric approach provides reliable stereo separation without requiring additional complex optical components or eyewear.
3Ease of operation
If curved-surface imaging element is used, then special glasses are eliminated, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs a curved-surface imaging element with a spherical geometry that provides inherent stereo image separation. While manufacturing precision is required for the curved surface, the design simplifies the overall system by eliminating the need for complex glass components, and the curved surface geometry itself provides the necessary optical function.
