Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used for generating emulsion, amplifying nucleic acids, and recovering products, then flexibility and adaptability are maintained, but substantial time input and user effort are required
Solution Approach 1:
The system enables automated self-service processing where the apparatus automatically performs emulsion generation, nucleic acid amplification, and product recovery without requiring substantial user input. The system manages its own operations through integrated control mechanisms that coordinate the various units (emulsion generation, amplification, breaking, and purification) to execute the complete workflow autonomously.
Solution Approach 2:
Manual mechanical operations are replaced with automated mechanical and electronic systems. The apparatus uses automated dispensing, magnetic separation, and controlled thermal cycling to substitute human-operated mechanical processes, thereby increasing productivity while maintaining precise control over the biological materials.
2Reliability
If traditional centrifugation methods are used to break emulsion and separate components, then effective separation is achieved, but repeated centrifugation is required to remove oil and surfactants
Solution Approach 1:
The system extracts and removes oil and surfactant components from the emulsion using automated breaking and purification units. These units employ chemical breaking agents and purification techniques that selectively remove unwanted components in a single or limited number of steps, eliminating the need for repeated centrifugation cycles while maintaining effective separation of nucleic acid products.
Solution Approach 2:
The system changes the chemical and physical parameters of the emulsion system by introducing breaking agents that alter the emulsion stability and enable phase separation. This parameter change allows for more efficient single-step or limited-step separation processes compared to traditional repeated centrifugation, reducing processing time while maintaining reliability.
3Reliability
If manual processing steps are performed, then precise control over biological materials is possible, but damage or modification of biological materials may occur
Solution Approach 1:
The automated system performs all processing steps without manual intervention, eliminating human error and the risk of accidental damage to biological materials. The self-service nature of the apparatus ensures consistent, gentle handling of nucleic acids through programmed operations, maintaining biological integrity while simplifying the user experience to minimal input requirements.
4Manufacturing precision
If multiple centrifugation steps are used to purify nucleic acids, then thorough purification is achieved, but the process becomes time-consuming and complex
Solution Approach 1:
The system merges multiple purification functions into integrated units that combine breaking, separation, and purification steps. The emulsion breaking unit and nucleic acid purification unit work together to achieve thorough purification in a streamlined sequence, reducing the number of discrete steps and overall process complexity while maintaining high purification quality through automated control.
