Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional organ procurement methods are used, then mobile staff can perform procurement procedures, but there is no precise controlled delivery of preservation solution and no suitable systems for maintaining optimal perfusate parameters
Solution Approach 1:
The patent combines multiple functions (pump, thermal control, sensors, and control module) into a single integrated portable enclosure. This merging resolves the contradiction by providing precise controlled delivery of preservation solution while maintaining portability and reducing the complexity of coordinating multiple separate devices.
Solution Approach 2:
The portable enclosure serves multiple functions simultaneously: it houses the pump, provides thermal control through heating/cooling elements, contains sensors for monitoring, and includes a control module for automation. This multi-functionality enables precise perfusate delivery without requiring separate specialized equipment for each function.
2Reliability
If conventional methods are used, then organ procurement can be performed by mobile staff, but there are no suitable systems for maintaining optimal perfusate parameters during the procedure
Solution Approach 1:
The patent incorporates sensors that continuously monitor perfusate parameters (temperature, flow, pressure) and feed this information back to the control module. The control module automatically adjusts the pump and thermal control elements to maintain optimal parameters, eliminating the need for manual monitoring and adjustment while ensuring reliable parameter maintenance.
Solution Approach 2:
The system performs self-regulation through automated feedback control. The control module continuously adjusts pump speed and thermal elements based on sensor input, allowing the system to maintain optimal perfusate parameters autonomously without requiring constant manual intervention, thus improving both reliability and ease of operation.
3Reliability
If precise controlled delivery of preservation solution is implemented, then unexplained failures in organ recipients can be reduced, but the system becomes more complex
Solution Approach 1:
By integrating the pump, thermal control system, sensors, and control module into a single portable enclosure, the patent achieves precise controlled delivery of preservation solution that improves organ recipient outcomes while avoiding the complexity of coordinating multiple separate devices. The unified design maintains reliability without proportionally increasing system complexity.
