Clinical Data Logger Time Shift Feature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clinical data logging devices face challenges in training users and testing due to complex scheduling requirements, which are difficult to replicate in a time-efficient manner, especially for long-term clinical investigations.
Innovation Solution
A time shift feature on the device allows users to selectively advance or retard the clock to specific points in the health monitoring schedule, enabling the device to operate as if it had reached that point in real time, facilitating training and testing while maintaining accurate data logging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device operates according to a complex clinical schedule spanning months or years, then data collection accuracy is improved, but training and testing efficiency deteriorates due to the time required to reach various scheduled events
Solution Approach 1:
The time shift feature enables testers and trainers to skip ahead through scheduled time periods by adjusting the device clock to future dates, allowing rapid progression through months or years of clinical schedule without waiting for actual time to pass, thus dramatically improving training and testing efficiency while preserving data collection accuracy
2Productivity
If the clock is adjusted to a future point in the schedule, then training and testing efficiency is improved by reaching events of interest quickly, but data integrity may deteriorate if the device behavior does not match real-time operation
Solution Approach 1:
The device provides feedback mechanisms that confirm whether adjusting the clock to a future date produces the expected behavior and data collection patterns, allowing testers to verify that time-shifted operation maintains data integrity equivalent to real-time operation
Data Source
AI summary
A health monitoring device that includes a data logger module that collects health information from a subject or clinician during specific time ranges that are part of a health monitoring schedule. The collected health information and/or the time ranges are determined in part by the content of the collected health information. The device records the collected health information along with a time stamp. The device also includes a clock and a time shift mode that allows a user to adjust the clock to a specified point in the health monitoring schedule so that the device operates at the specified point in the same manner as if the device had reached the specified point without intervention by the user to adjust the clock.
