Solution Overview

Problem

Conventional portable medical devices often generate false or inappropriate alarms due to their reliance on single alerting schemes, which can be inconvenient and ineffective in various environmental conditions.

Innovation Solution

The integration of onboard situational awareness sensors that detect current conditions and dynamically select a preferred alerting scheme from multiple options, using a decision module to generate alerts tailored to the user's environment and reactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single default alerting scheme is used, then the device complexity is reduced, but the adaptability to different environmental conditions deteriorates

Engineering Contradiction:
Improvealerting scheme complexityVSAvoidadaptability to environmental conditions
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic alerting schemes that automatically adjust alert behavior based on real-time environmental conditions detected by sensors. The system transitions from static default alerts to dynamic adaptive alerts that change characteristics (sound, light, vibration) according to detected conditions such as ambient light levels, noise levels, and user presence, thereby improving adaptability without requiring complex manual configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system employs self-service mechanisms where the device autonomously selects and adjusts alerting schemes based on environmental sensor data without requiring user intervention. The device monitors its own operational context and automatically adapts alert behavior, eliminating the need for users to manually configure alert settings while maintaining simplicity of use.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If conventional alarm features are used, then the ease of operation is maintained, but the reliability of appropriate alerting deteriorates

Engineering Contradiction:
Improveuser convenienceVSAvoidreliability of appropriate alerting
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system incorporates feedback mechanisms where environmental sensors continuously monitor conditions and feed this information back to the alerting controller. The controller adjusts alert characteristics based on this feedback loop, ensuring alerts are appropriate for current conditions. This automatic feedback-based adjustment improves alert reliability while maintaining ease of operation, as users do not need to manually configure settings.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical configuration of alert settings with automated sensor-based detection and decision-making systems. Instead of requiring users to physically navigate menus and adjust parameters, the system uses electronic sensors and algorithms to automatically determine appropriate alert behavior, improving both reliability and ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple alerting schemes are available, then the adaptability to different conditions is improved, but the device complexity increases

Engineering Contradiction:
Improvevariety of alerting optionsVSAvoidalerting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the alerting system into distinct modular components: environmental sensors (light, noise, proximity), a decision-making controller, and multiple alert output mechanisms (visual, auditory, haptic). Each component performs a specific function, and the controller intelligently selects and combines these segments based on detected conditions. This modular segmentation allows for multiple alerting options while managing complexity through clear functional separation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements multi-functional alerting elements that can operate in multiple modes. For example, a single alert mechanism can function as visual, auditory, or haptic feedback depending on environmental conditions. This universality allows the system to provide diverse alerting options without requiring separate dedicated components for each alert type, thereby managing complexity while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A portable medical device and related operating methods are provided. One operating method involves a portable medical device that includes a situational awareness sensor. The method begins by detecting an alert condition associated with operation of the portable medical device. In response to the alert condition, the situational awareness sensor performs a scanning operation to obtain sensor data indicative of a current environmental status of the portable medical device. The device can then select a preferred alerting scheme from a plurality of different available alerting schemes, where the preferred alerting scheme is influenced by the sensor data. The device then generates an alert for the alert condition in accordance with the preferred alerting scheme.
