Buttonless Physiological Meter Clock Reset Detection

Solution Overview

Problem

Buttonless physiological monitors lack the ability to record temporal parameters, rendering stored measurements worthless without time stamps, and are prone to inefficiencies and errors due to the absence of user input interfaces.

Innovation Solution

A method is implemented in a physiological measurement system that links time records to each measurement using a microprocessor, clock, and memory, without user input interfaces, by determining if the clock has been reset and setting flags to ensure accurate temporal parameter association with measurements, and communicating with remote processors to adjust time stamps as necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a buttonless physiological meter is used, then manufacturing cost is reduced and operational simplicity is improved, but the ability to record and manipulate temporal parameters is lost

Engineering Contradiction:

Core Design Contradiction:

Ease of manufactureVSLoss of information

Solution Approach 1:

The system automatically detects clock resets and self-corrects temporal parameters without requiring user input. The microprocessor monitors the clock status, detects resets, and automatically adjusts time stamps on stored measurements, allowing the buttonless meter to maintain accurate temporal information autonomously

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements a feedback mechanism where the microprocessor continuously monitors the clock status and detects when the clock has been reset. Based on this feedback, the system automatically flags affected measurements and corrects temporal parameters, ensuring accuracy without user intervention

Inventive Principle:

Principle #23Feedback
