Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single optical system is used for photographing the anterior segment, then the device structure is simple, but the imaging precision and detail capture are insufficient
Solution Approach 1:
The anterior segment photographing system is divided into multiple optical systems (first and second optical systems) that photograph the anterior segment from different directions. Each optical system captures images from its specific viewpoint, and the combination of these segmented views achieves comprehensive high-precision imaging of the anterior segment that cannot be obtained by a single optical system.
2Manufacturing precision
If multiple optical systems are added to capture detailed anterior segment images, then imaging precision improves, but device complexity increases
Solution Approach 1:
Multiple optical systems are merged into a single integrated anterior segment photographing system that shares common components such as the objective lens and light source. The first and second optical systems are combined to photograph the anterior segment from different directions simultaneously, achieving high-precision imaging while reducing overall system complexity through component sharing.
3Area of stationary object
If a single viewpoint is used for photographing, then the optical system is simple, but the field of vision and stereoscopic effect are limited
Solution Approach 1:
The system transitions from single-viewpoint two-dimensional imaging to multi-viewpoint three-dimensional imaging by adding the first and second optical systems that photograph from different directions. This dimensional expansion provides a broader field of vision and creates natural stereoscopic effects, allowing comprehensive observation of the anterior segment from multiple spatial perspectives.
