Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional calibration method is used with fixed control rules, then the calibration process is simple, but the calibration precision is insufficient due to manufacturing and assembly errors
Solution Approach 1:
The patent transforms fixed control rules into dynamic adaptive control rules that automatically adjust based on real-time feedback from the infusion tube. The controller modifies control parameters dynamically during calibration to compensate for manufacturing and assembly errors, achieving higher precision without manual intervention.
Solution Approach 2:
The patent introduces a feedback mechanism where the controller receives calibration data from the infusion tube and automatically adjusts control rules based on this feedback. This closed-loop system enables the pump to learn and adapt to specific tube characteristics, improving calibration accuracy while maintaining operational simplicity.
2Adaptability or versatility
If calibration parameters are manually adjusted for different infusion tubes, then the adaptability to different tube types is improved, but the ease of operation deteriorates due to increased manual intervention
Solution Approach 1:
The patent enables the infusion pump to automatically identify and adapt to different infusion tube types without user intervention. The system performs self-calibration by autonomously adjusting control parameters based on detected tube characteristics, eliminating the need for manual parameter adjustment while maintaining high adaptability.
Solution Approach 2:
The patent automatically changes control parameters based on the identified infusion tube type. The system stores multiple sets of control parameters corresponding to different tube types and automatically selects and adjusts the appropriate parameters, achieving versatility without requiring user knowledge or manual intervention.
3Measurement precision
If generic control rules are used for all infusion consumables, then the device complexity is low, but the measurement precision deteriorates for specific consumable types
Solution Approach 1:
The patent segments the control rules into multiple specific sets, each optimized for different types of infusion consumables. The controller identifies the specific consumable type and selects the corresponding control rule set, enabling precise control for each consumable type while keeping the overall system manageable through automated selection.
Solution Approach 2:
The patent creates a universal calibration system that can handle multiple types of infusion consumables through a single automated framework. The system universally applies the same calibration process but dynamically adjusts parameters based on consumable type, achieving both precision and versatility without requiring separate manual calibration procedures for each consumable type.
