Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If infusion pumps are designed as non-modular units, then device complexity is reduced, but adaptability and sustainability deteriorate
Solution Approach 1:
The infusion pump is divided into modular components: a reusable driving device containing the motor-gear unit and control unit, and disposable pump units containing the pump rotor and giving set. This segmentation allows the driving device to be reused across multiple pump units, improving adaptability and sustainability while maintaining manageable complexity through standardized interfaces.
Solution Approach 2:
The driving device is designed as a universal platform that can operate with different types of pump units through standardized coupling mechanisms. The receptacle in the driving device can releasably receive various pump unit designs, allowing one driving device to serve multiple functions and applications, thereby improving adaptability without proportionally increasing complexity.
2Adaptability or versatility
If trochoidal pump devices are designed for modular and reusable applications, then sustainability and adaptability improve, but device complexity increases
Solution Approach 1:
The trochoidal pump device is segmented into a reusable driving device and disposable pump units. The driving device contains the complex motor-gear unit and control electronics, while the pump units contain simpler mechanical pumping components. This segmentation allows the complex parts to be reused while the simpler parts are disposed of, improving sustainability without permanently increasing overall system complexity.
Solution Approach 2:
The pump units are designed as disposable components that are replaced after use, while the expensive and complex driving device is reused. This approach allows the modular design to improve sustainability and adaptability while containing complexity in the reusable portion of the system.
3Adaptability or versatility
If reusable components are implemented in infusion pumps, then sustainability improves, but manufacturing precision requirements increase
Solution Approach 1:
By segmenting the system into reusable and disposable parts, the manufacturing precision requirements are concentrated on the reusable driving device components that require precise assembly (motor-gear unit, control unit, receptacle). The disposable pump units can have lower precision requirements since they are not reused, thereby improving sustainability without excessively raising overall manufacturing precision demands.
Solution Approach 2:
The driving device is designed as a universal reusable platform with standardized interfaces that must be manufactured with high precision to ensure compatibility with various pump units. This concentrates precision manufacturing requirements on a single reusable component rather than requiring all components to meet high precision standards, improving sustainability while managing manufacturing complexity.
4Ease of operation
If modular pump units with releasable coupling are used, then ease of operation and sustainability improve, but reliability may deteriorate due to connection issues
Solution Approach 1:
The system is segmented into modular components with standardized coupling interfaces. The receptacle in the driving device and the coupling in the pump units are designed to mate precisely, providing both ease of operation for attachment/detachment and reliable fluid-tight connections. The segmentation allows for simple user operation while maintaining connection integrity through carefully designed interfaces.
Solution Approach 2:
The control unit in the driving device receives feedback signals from the pump units to verify proper connection and operation. This feedback mechanism ensures that the releasable coupling is properly engaged and functioning, maintaining reliability while preserving the ease of operation benefits of modular design.
