Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic discs are suspended in liquid and exposed to dynamic magnetic field for rotation, then remote and non-invasive detection of fluid characteristics is enabled, but device complexity increases due to need for magnetic field generator, light source, and light sensor system
Solution Approach 1:
The patent replaces direct mechanical contact and invasive measurement methods with a field-based system. Magnetic fields are used to rotate the discs remotely without physical contact, and optical fields are used to detect the rotation state, eliminating the need for direct mechanical interaction with the liquid sample.
Solution Approach 2:
The magnetic discs serve as intermediaries that translate fluid characteristics into detectable optical signals. The discs are suspended in the liquid and their rotation, driven by magnetic fields, modulates the light beam passing through the liquid, allowing indirect detection of fluid properties through the discs' motion.
2Loss of information
If magnetic discs rotate in liquid under dynamic magnetic field, then light beam intensity is modulated for detection, but measurement precision requirements increase to accurately detect fluid characteristics and agent presence
Solution Approach 1:
The system utilizes changes in light intensity (optical property) as the magnetic discs rotate. The rotating discs modulate the light beam passing through the liquid, creating detectable intensity variations that encode information about fluid characteristics and the presence of target agents.
Solution Approach 2:
The magnetic discs undergo rotational motion when exposed to the dynamic magnetic field. This rotation creates periodic modulation of the light beam intensity, transforming the fluid's physical properties into measurable oscillating optical signals that can be analyzed for precise detection.
3Adaptability or versatility
If targeting material with affinity for agent is attached to magnetic discs, then specific agent detection is enabled, but manufacturing precision requirements increase for coating and attaching targeting material
Solution Approach 1:
The magnetic discs are equipped with targeting materials that have specific affinity for particular agents. This localized functionalization allows the discs to selectively bind to target molecules in the liquid, enabling specific detection of desired substances while leaving other components unaffected.
Solution Approach 2:
The magnetic discs are constructed as composite structures combining magnetic material with targeting material coatings. This composite design integrates the magnetic response properties needed for remote actuation with the biological recognition properties required for specific agent detection.
