Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional eye imaging cameras use fixed optical components, then the system structure is simple, but the adaptability and versatility are poor
Solution Approach 1:
The optical system is divided into separate, interchangeable modules including multiple lenses and optical filters that can be independently selected and positioned. Each lens and filter is a distinct component that can be moved or replaced without affecting the entire system structure, enabling different imaging modalities while maintaining manageable complexity.
Solution Approach 2:
The system incorporates movable and adjustable optical components that can be dynamically repositioned or exchanged during operation. The lenses and filters are designed to be relocatable within the optical path, allowing the system to adapt to different imaging requirements through dynamic reconfiguration rather than being fixed in a single static arrangement.
2Adaptability or versatility
If lenses or optical filters are made interchangeable, then the versatility improves, but the device complexity increases
Solution Approach 1:
The system employs universal mounting interfaces and standardized optical paths that accommodate multiple different lenses and filters through a common framework. The interchangeable components are designed to work within a unified system architecture, allowing versatility through multiple options while avoiding the complexity that would arise from entirely separate systems for each component type.
Solution Approach 2:
Specific regions of the optical system are designed with particular qualities for component interchangeability, such as standardized mounting interfaces and positioning mechanisms at lens and filter locations, while other parts of the system maintain simpler fixed structures. This localized application of complexity only where needed for interchangeability minimizes overall system complexity while achieving the desired versatility.
3Ease of operation
If the system allows easy replacement of components, then the ease of operation improves, but the reliability may worsen
Solution Approach 1:
The interchangeable lenses and filters are pre-configured with standardized mounting features and alignment mechanisms that ensure proper installation and optical alignment before use. The components are designed in advance with compatibility features built-in, allowing easy replacement while maintaining system reliability through pre-established mechanical and optical interfaces that prevent misalignment or improper installation.
