Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input interfaces are used for setting adjustable parameters, then users can directly input treatment parameters, but the complexity of setting adjustments increases and error probability rises
Solution Approach 1:
The system automatically calculates and determines the adjustable settings based on the target treatment parameter entered by the user. The blood treatment apparatus performs self-service by computing the required pump rates and other technical parameters without requiring manual calculation or multiple manual adjustments, thereby reducing operational complexity while maintaining ease of use.
Solution Approach 2:
The system transforms the user's input of a single target treatment parameter into automatically calculated technical parameter values for the blood treatment apparatus. This parameter transformation approach simplifies the user's task while the system handles the complexity of converting high-level treatment goals into specific operational parameters.
2Reliability
If multiple adjustable settings are manually configured to achieve treatment goals, then treatment targets can be achieved, but the likelihood of errors increases due to interdependent settings
Solution Approach 1:
The blood treatment apparatus automatically determines the correct settings by calculating them based on the target treatment parameter. This self-service capability ensures that interdependent settings are correctly coordinated without requiring the user to manually adjust multiple parameters, thereby improving reliability while maintaining operational simplicity.
Solution Approach 2:
The system provides feedback to the user by displaying the calculated adjustable settings and technical parameter values. This allows the user to verify that the automatically determined settings are appropriate before initiating treatment, enhancing reliability through user confirmation while keeping the operation simple.
3Productivity
If users manually determine and adjust multiple interdependent settings, then treatment goals can be achieved, but the time required for setup increases
Solution Approach 1:
The system performs preliminary calculation of all necessary adjustable settings and technical parameter values automatically based on the target treatment parameter. This preliminary action eliminates the need for users to spend time manually determining and coordinating multiple interdependent settings, thereby improving treatment preparation efficiency without time loss.
Solution Approach 2:
The blood treatment apparatus performs self-service by automatically calculating and setting the technical parameters required for treatment. This automation significantly reduces the time users would otherwise spend on manual configuration while maintaining high treatment preparation efficiency.
4Ease of operation
If a simplified input interface is used for setting parameters, then ease of operation improves, but the system must automatically calculate multiple technical parameters
Solution Approach 1:
The system implements parameter transformation by accepting a simplified target treatment parameter input from the user and automatically calculating the corresponding technical parameter values. This approach maintains user interface simplicity while necessitating automatic calculation, as the system must convert the high-level treatment goal into specific operational parameters.
Solution Approach 2:
The blood treatment apparatus performs self-service by automatically determining all necessary technical parameters based on the user's simple input. This self-service capability enables the system to handle the complexity of parameter calculation internally while presenting a simplified interface to the user.
