Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual preservative addition is used in collection tanks, then the system is simple to operate, but the preservative concentration cannot be strictly controlled leading to decay or interference with heparin extraction
Solution Approach 1:
The system employs level sensors that detect the mucosa level in the collection tank and provide feedback to the control unit, which automatically activates the pump and preservative dosing system. This closed-loop feedback mechanism ensures precise preservative concentration control without requiring complex manual monitoring and adjustment procedures.
Solution Approach 2:
The system is designed to automatically perform preservative dosing and mucosa transfer operations without continuous human intervention. The control unit autonomously manages the entire process from detecting mucosa accumulation to dosing preservative and transferring the mixture, making the complex automation transparent to the user while maintaining simple operation.
2Reliability
If preservative concentration is increased to prevent decay, then mucosa preservation is improved, but heparin extraction is interfered with
Solution Approach 1:
The system precisely controls the preservative dosing parameters based on the actual mucosa volume detected by level sensors. By adjusting the preservative amount to match the exact mucosa quantity in the tank, the system achieves reliable preservation while avoiding excessive preservative concentrations that would interfere with subsequent heparin extraction processes.
Solution Approach 2:
Instead of adding a fixed excessive amount of preservative, the system adds only the partial amount necessary based on real-time mucosa level detection. This ensures sufficient preservation without over-dosing, thereby preventing interference with heparin extraction while maintaining reliable mucosa preservation.
3Productivity
If multiple collection tanks and storage reservoirs are used, then processing capacity is increased, but the risk of widespread decay increases with any dosing mishap
Solution Approach 1:
The system divides the processing into multiple independent collection tanks, each equipped with its own automated dosing and control system. This segmentation isolates potential dosing errors to individual tanks, preventing widespread decay across all tanks and reservoirs while maintaining high overall processing capacity through parallel operation.
Solution Approach 2:
Each collection tank is equipped with level sensors and automated control systems that continuously monitor and adjust preservative dosing. This feedback mechanism ensures reliable preservation in each tank independently, preventing the propagation of dosing errors across the entire system while enabling high productivity through multiple concurrent tanks.
4Measurement precision
If automated metering control is implemented, then preservative dosing precision is improved, but the number of parts and connections increases making installation and cleaning difficult
Solution Approach 1:
The pump unit is designed with multi-functionality, serving both as a mucosa transfer pump and a preservative dosing pump. This universal design reduces the total number of separate components and connections required for automated metering, thereby maintaining dosing precision while simplifying installation and cleaning procedures compared to systems with separate dedicated pumps for each function.
