AED Attention Direction via Segmented Sensory Outputs

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current automated external defibrillators (AEDs) divert users' attention from the victim during a rescue attempt, as instructions are primarily delivered through the AED unit, necessitating a better method to direct the user's attention effectively.

Innovation Solution

The integration of sensory outputs in both the AED unit and ancillary components, such as pads, allows for controlled programming to direct the user's attention between the unit and the ancillary components, utilizing displays and speakers to provide instructions and guidance during a rescue attempt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If instructions are delivered through the AED unit, then the user receives clear guidance, but the user's attention is diverted from the victim

Engineering Contradiction:

Improveinstruction deliveryVSAvoiduser attention focus

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent segments the instruction delivery function across multiple components: the AED unit and the pads. Each component has its own sensory outputs (displays and speakers) that can independently provide instructions to the user, allowing the user to receive guidance while maintaining focus on the victim

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pads serve as an intermediary component between the AED unit and the user. They relay instructions and feedback to the user directly at the point of contact with the victim, reducing the need for the user to look at or interact with the main AED unit during critical moments

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the user focuses on the AED unit for instructions, then the user receives guidance, but the rescue efficiency decreases

Engineering Contradiction:

Improveuser guidanceVSAvoidrescue efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

By dividing the guidance function between the AED unit and pads, the system allows continuous instruction delivery without requiring the user to shift attention between components. The pads provide localized feedback that the user can access while maintaining their position and focus on the victim

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pads provide self-contained sensory outputs that deliver instructions and feedback directly to the user's field of view during the rescue process, eliminating the need for the user to service or monitor the main AED unit interface during critical operations

Inventive Principle:

Principle #25Self-service

AI summary

A medical device having a unit in communication with ancillary components wherein the unit and the ancillary components each have a sensory output through which communication with a user of the medical device may be accomplished and to which the user's attention directed. In one aspect, the medical device is an AED unit with associated pads, which are an ancillary component electrically connected to the AED unit. In this illustrative example, the unit has a unit sensory output (e.g., a speaker or a display), and the pads, and/or their associated packaging, have an ancillary sensory output (e.g. a speaker or display). Programming in the AED unit controls output to the sensory outputs such that the user's attention is directed between the unit and the ancillary components.
