Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure indicators are integrated into the fluid conductor, then pressure monitoring capability is improved, but device complexity increases
Solution Approach 1:
The pressure indicator is integrated directly into the fluid conductor structure, merging the monitoring function with the existing fluid delivery component. This eliminates the need for separate pressure monitoring devices and reduces overall system complexity while maintaining effective pressure monitoring capability.
Solution Approach 2:
The fluid conductor structure itself serves as the pressure indicator through its elastic deformation properties. The material and structure are designed to automatically indicate pressure changes through visible deformation, eliminating the need for external sensing mechanisms or additional components.
2Reliability
If diagnostic indicators are added to monitor treatment conditions, then treatment efficacy is improved, but device complexity increases
Solution Approach 1:
Multiple diagnostic functions (pressure indication, temperature sensing, pH sensing) are merged into a single integrated fluid conductor structure. This consolidation provides comprehensive treatment monitoring while minimizing the number of separate components and reducing overall device complexity.
Solution Approach 2:
The fluid conductor is designed with multi-functionality, serving both as a fluid delivery mechanism and as an integrated diagnostic platform. The same structure provides pressure indication through elastic deformation and can incorporate temperature and pH sensing capabilities, allowing one component to perform multiple monitoring functions.
3Reliability
If real-time feedback mechanisms are implemented, then treatment consistency is improved, but device complexity increases
Solution Approach 1:
The elastic pressure indicators provide continuous visual feedback on pressure conditions throughout the fluid conductor. This real-time feedback allows operators to monitor treatment consistency and make immediate adjustments if pressure deviations occur, ensuring reliable and consistent treatment delivery.
