Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single imaging mode is used, then the device structure is simple, but the detection accuracy is insufficient
Solution Approach 1:
The device is segmented into multiple independent detection modules, each with its own light source and optical sensor arranged at different positions. This allows parallel operation of multiple imaging modes without requiring complex sequential switching mechanisms, thereby improving detection accuracy while controlling structural complexity.
Solution Approach 2:
The detection device is designed to perform multiple imaging functions simultaneously through different detection modules. Each module can operate independently or in combination, enabling the system to capture images in various modes (transmission, reflection, fluorescence) using a single integrated structure, thus resolving the contradiction between multi-functionality and structural simplicity.
2Measurement precision
If light is emitted only from above the culture vessel, then the optical path is simple, but the image quality is insufficient
Solution Approach 1:
The optical paths are extended from a single vertical dimension to multiple spatial dimensions. Light sources and optical sensors are positioned at different heights and angular positions around the culture vessel, enabling illumination and detection from multiple directions simultaneously. This multi-dimensional optical arrangement improves image quality by capturing transmission, reflection, and fluorescence signals without requiring excessively complex optical components.
3Adaptability or versatility
If only one optical sensor is used, then the device structure is simple, but the detection capability is limited
Solution Approach 1:
The detection system is divided into multiple optical sensor units positioned at different locations and orientations. Each sensor is optimized for specific detection angles and wavelengths, allowing the system to capture diverse optical signals (transmitted light, reflected light, fluorescence) simultaneously. This segmented approach enhances detection versatility while maintaining relatively simple individual sensor structures.
Solution Approach 2:
Multiple optical sensors with different detection capabilities are merged into a single integrated detection device. The sensors are positioned to detect light from different directions and wavelengths, enabling the system to perform multiple detection functions (transmission imaging, reflection imaging, fluorescence detection) through a unified structure, thereby improving adaptability without proportionally increasing overall complexity.
