Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single area is used for both detection and heating, then device complexity is reduced, but the ability to perform simultaneous detection and heating of different portions is limited
Solution Approach 1:
The device is divided into multiple functional areas: a detection area with a detector and a heating area with heating elements. These areas are circumferentially offset from each other, allowing independent operation on different portions of the microfluidic device. This segmentation enables simultaneous detection and heating without interference between the functions.
Solution Approach 2:
The detection area and heating area are arranged in a circumferential dimension around the rotation axis, rather than overlapping in the same spatial location. This dimensional arrangement allows both areas to access different portions of the rotating microfluidic device simultaneously, resolving the conflict between functional versatility and structural simplicity.
2Adaptability or versatility
If the microfluidic device is stationary, then device complexity is reduced, but operational versatility and efficiency are limited
Solution Approach 1:
The microfluidic device is made rotatable around a vertical axis, transforming it from a stationary to a dynamic component. This rotation allows different portions of the device to be sequentially positioned under the fixed detection area and heating area, enabling versatile operations including simultaneous detection and heating of different chambers or tracks without requiring multiple fixed components.
3Adaptability or versatility
If heating elements are fixed in position, then device complexity is reduced, but the ability to heat different portions specifically is limited
Solution Approach 1:
The heating system is segmented into multiple heating elements arranged circumferentially around the rotation axis. Each heating element can be independently controlled to heat specific portions of the microfluidic device as they pass underneath, enabling selective heating of different chambers or tracks without requiring a complex movable heating system.
4Device complexity
If detection and heating areas overlap, then device structure is simplified, but interference between detection and heating operations occurs
Solution Approach 1:
The heating function is extracted from the detection area and placed in a separate, circumferentially offset heating area. This separation eliminates thermal interference with the detector while allowing both functions to operate simultaneously on the rotating microfluidic device. The detector remains in its optimal detection position without exposure to heating radiation.
