Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex programming sequence is used to allow detailed parameter adjustment, then the machine can perform precise medical treatments, but the ease of operation deteriorates and requires trained professionals
Solution Approach 1:
The system automatically adjusts dependent parameters when a user modifies an independent parameter. The computing device detects changes in parameters and autonomously calculates and applies appropriate adjustments to related parameters, eliminating the need for manual programming of each parameter and reducing operational complexity while maintaining treatment precision
Solution Approach 2:
The system pre-establishes relationships between parameters and pre-configures adjustment rules. When a user modifies one parameter, the system has already prepared the corresponding adjustments for dependent parameters, allowing instant automatic adjustment without requiring the user to manually program each parameter sequence
2Adaptability or versatility
If manual entry of each parameter is required, then the user can control treatment details, but the time required for programming increases significantly
Solution Approach 1:
The computing device autonomously handles the adjustment of dependent parameters based on user input to independent parameters. This self-service mechanism automatically performs calculations and applies adjustments, eliminating the time-consuming manual entry of each parameter while preserving the ability to control treatment details through selective parameter modification
Solution Approach 2:
The system pre-configures parameter relationships and adjustment algorithms before treatment programming begins. This preliminary setup enables the system to instantly compute and apply parameter adjustments when users modify independent parameters, dramatically reducing programming time while maintaining treatment adaptability
3Reliability
If the machine prompts the user to check parameters after entry, then errors can be detected, but the machine cannot automatically correct mistakes
Solution Approach 1:
The system automatically detects parameter changes and autonomously adjusts dependent parameters to maintain consistency and prevent errors. This self-correcting mechanism goes beyond simple error detection by automatically compensating for inappropriate adjustments, eliminating the need for manual error correction while maintaining high reliability
Solution Approach 2:
The system continuously monitors parameter changes and provides automatic feedback adjustments. When a user modifies a parameter, the computing device detects the change, evaluates its impact on dependent parameters, and automatically applies corrective adjustments, creating a closed-loop feedback system that prevents errors rather than merely detecting them

AI summary
A graphical user interface for a medical system comprises a display device, an electronic processor that operates with the display device to display a plurality of screens including a programming screen by which a user can enter or modify medical treatment parameters employed by a machine to perform a medical treatment. When a user modifies a first medical treatment parameter, the processor is programmed to adjust at least one other medical treatment parameters depending on the first medical treatment parameters.
