Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dihedral corner reflector array is used to display images in the air, then the image is displayed at a plane-symmetrical position without aberration, but the ability to create depth and realistic visual experience is limited
Solution Approach 1:
The optical device is divided into multiple optical members with different thicknesses, where each optical member has a specific thickness value. This local variation in thickness creates different refraction effects for different regions, enabling depth creation while maintaining overall image display accuracy at the plane-symmetrical position.
Solution Approach 2:
The patent changes the thickness parameter of the optical members to create depth effects. By having optical members with different thickness values, the system can adjust the refraction rate and image formation position, thereby creating multiple depth layers without compromising the precision of the plane-symmetrical image display.
2Adaptability or versatility
If the optical device has varying thickness to create depth, then the visual experience is enhanced, but the device complexity increases
Solution Approach 1:
Multiple optical members with different thicknesses are combined into a single optical device structure. This merging approach allows the system to achieve depth perception through a unified component rather than separate elements, reducing overall system complexity while maintaining the depth creation capability.
Solution Approach 2:
The optical device with varying thickness serves multiple functions: it displays images at the plane-symmetrical position, creates depth perception, and controls image formation positions. This multi-functionality reduces the need for additional separate components, thereby reducing device complexity while enhancing versatility.
3Device complexity
If the optical device has constant thickness with varying refraction rate, then the structure is simplified, but the control over image formation positions becomes more difficult
Solution Approach 1:
The optical device has constant thickness throughout, but different regions have different refraction rates. This local variation in refraction rate allows for precise control over image formation positions while maintaining a simple and uniform structural design, resolving the contradiction between structural simplicity and positioning control.
