Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid sampling methods lack the capability to accurately record the time and date of sample acquisition, which is crucial for pharmacokinetic analyses due to time-sensitive fluid components that may change during drug absorption or excretion.
Innovation Solution
A fluid sampling device equipped with an absorbent member and a recorder that generates timestamp data, including the time and date of fluid absorption, ensuring accurate recording of sample acquisition times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional fluid sampling methods are used, then the sampling process is simple, but the time and date of sample acquisition cannot be accurately recorded
Solution Approach 1:
The patent combines the absorbent member (for fluid absorption) and the recorder (for timestamp recording) into a single integrated sampling device. This merging allows the device to simultaneously perform both fluid sampling and accurate time/date recording without requiring separate systems, thereby improving measurement precision while controlling device complexity.
Solution Approach 2:
The sampling device is designed to perform multiple functions: absorbing fluid through the absorbent member and recording timestamp data through the recorder. This multi-functionality enables a single device to address both the fluid sampling requirement and the time recording requirement, resolving the contradiction between improved measurement precision and device complexity.
2Reliability
If accurate timestamp recording is implemented, then pharmacokinetic analysis accuracy is improved, but device complexity increases
Solution Approach 1:
The recorder is designed to automatically generate and store timestamp data without requiring external intervention or complex programming. The absorbent member triggers the recording function through its own absorption action, creating a self-service mechanism that improves reliability while minimizing the complexity of the recorder system.
Solution Approach 2:
The recorder is pre-configured to automatically capture and store time and date information at the moment of fluid absorption. This preliminary setup ensures that timestamp data is reliably recorded without requiring complex real-time processing or external systems, thereby improving pharmacokinetic analysis accuracy while controlling device complexity.
