Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional PCR apparatus with integrated cell lysis components is used, then cell lysis function is provided, but the apparatus becomes expensive and cumbersome
Solution Approach 1:
The system divides the cell lysis functionality into a separate standalone device that can be used independently from the PCR apparatus. The cell lysis device includes an ultrasonic transducer and chamber that can be operated separately, allowing the PCR apparatus to focus only on amplification while the cell lysis device handles sample preparation.
Solution Approach 2:
The cell lysis device is designed to work with multiple types of samples and can be integrated with different PCR apparatuses. The ultrasonic transducer system can process various cell types and the device can be adapted to different experimental requirements, making it a universal solution for cell lysis.
2Ease of operation
If standalone cell lysis devices are used, then portability and versatility are improved, but efficiency and performance are reduced
Solution Approach 1:
The system incorporates a frequency sweep mechanism that automatically identifies the resonant frequency of the ultrasonic transducer by monitoring power consumption across a range of frequencies. This feedback loop ensures the transducer operates at maximum efficiency regardless of variations in the standalone device, maintaining high performance while preserving portability.
Solution Approach 2:
The system dynamically adjusts the operating frequency parameter of the ultrasonic transducer to match its resonant frequency. By sweeping through a frequency range and identifying the peak power consumption point, the system optimizes the transducer's performance parameters to achieve maximum cell lysis efficiency in the standalone device.
3Use of energy by moving object
If frequency optimization is implemented, then active power usage is maximized, but additional monitoring and control components are required
Solution Approach 1:
The system performs self-characterization by automatically sweeping through frequencies and identifying its own resonant peak. The microcontroller monitors the transducer's power consumption across frequencies and autonomously determines the optimal operating point without requiring external calibration or complex control systems.
Solution Approach 2:
The system replaces complex mechanical tuning mechanisms with an electronic frequency sweep and monitoring approach. Instead of physically adjusting the transducer, the system uses electronic control to sweep through frequencies and identify the optimal operating point, simplifying the overall control architecture while maximizing power efficiency.
