Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional detection methods and devices are used for infusion liquid parameters, then detection can be performed, but the detection results are not reliable and time-consuming
Solution Approach 1:
The detection assembly is nested within the infusion bottle cap structure. The cap includes a detection chamber where detection reagents are pre-loaded, and the infusion liquid flows through this chamber during normal infusion, enabling automatic detection without separate detection devices or procedures.
Solution Approach 2:
The infusion liquid itself serves as the sample for detection by flowing through the detection chamber and reacting with pre-loaded reagents. The system performs self-detection during the infusion process, eliminating the need for separate sampling and detection operations.
2Measurement precision
If detection devices are added to the infusion system, then parameter detection is enabled, but the device complexity increases
Solution Approach 1:
The detection function is merged with the infusion bottle cap. The cap structure integrates the detection chamber, reagent storage, and fluid pathway into a single component that is already part of the infusion system, avoiding addition of separate detection devices.
Solution Approach 2:
The infusion cap serves multiple functions: it seals the bottle, connects to the infusion tube, and performs parameter detection. This multi-functionality eliminates the need for separate detection equipment and reduces overall system complexity.
3Measurement precision
If infusion liquid is sampled for detection, then parameter measurement is possible, but liquid loss and contamination risk increase
Solution Approach 1:
The detection process occurs continuously during the infusion flow without interrupting or diverting the liquid. The infusion liquid flows through the detection chamber and continues into the infusion tube, maintaining continuous useful action without loss.
Solution Approach 2:
The detection chamber acts as an intermediary where a small portion of the flowing liquid interacts with reagents. This intermediary chamber allows measurement without requiring significant liquid sampling or breaking the sealed infusion system.

Implementation Method 1
Taking the pH value as an example, during each infusion liquid preparation process, it is necessary to monitor whether the pH value is in a range maximizing the medicine efficacy
Implementation Method 2

AI summary
Disclosed is an infusion accessory capable of detecting infusion liquid parameters, which is a lid body, comprising a first portion provided with one or more detecting members and a second portion having one or more liquid channels. Relative position changes may occur between the first portion and the second portion, the liquid channels and the detecting members may be switched between an open position and a closed position as position changes occur between the first portion and the second portion, the open position enables communication between the liquid channels and the detecting members so that liquid in the liquid channels may flow into the detecting members, the close position enables sealing between the liquid channels and the detecting members so that the liquid in the liquid channels cannot flow into the detecting members and the liquid that already flows into the detecting members cannot return to the liquid channels.
