Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual or partially automated pipetting devices are used for sampling, then sampling can be performed, but the process becomes labor intensive and complex with significant cost and human error
Solution Approach 1:
The patent replaces manual pipetting operations with an automated sampling system that uses a sampling valve, fluid supply system, and computer control to automatically extract and transport samples. The mechanical manual pipetting is substituted with an automated fluid handling system controlled by a computer, eliminating human error and improving efficiency.
Solution Approach 2:
The sampling system is designed to be self-service through automated control. The computer controls the sampling valve, fluid supply, and sample transport without requiring manual intervention. The system automatically selects reactors, extracts samples, and transports them to storage containers based on pre-programmed parameters.
2Measurement precision
If manual sampling methods are used, then sampling can be performed, but accuracy and reproducibility are compromised due to human error
Solution Approach 1:
The patent replaces manual sampling operations with an automated system that uses a sampling valve, fluid supply system, and computer control to automatically extract and transport samples. The mechanical manual pipetting is substituted with an automated fluid handling system controlled by a computer, eliminating human error and improving efficiency.
Solution Approach 2:
The system incorporates feedback mechanisms where the computer monitors and controls the sampling process parameters. The system can detect when sampling is complete and automatically adjust subsequent operations. This feedback control ensures consistent, reproducible sampling results.
3Quantity of substance
If current sampling systems are used, then sampling can be performed, but a relatively large sample volume is required
Solution Approach 1:
The patent uses a fluid supply system with pneumatic or hydraulic principles to push samples through channels. The fluid supply system uses pressure differential to transport samples from the reactor through the sampling valve and extraction channel to the storage container, enabling efficient and controlled sample transfer with minimal volume requirements.
Solution Approach 2:
The system changes the physical parameters of sample transport by using fluid pressure differentials and controlled flow rates. The sampling valve and fluid supply system allow precise control over sample volume and flow characteristics, enabling efficient sampling with smaller volumes compared to traditional methods.
