Solution Overview

Problem

Existing portable automated external defibrillators face issues with electrode cable damage during transport and inadequate power supply for defibrillation, leading to delayed treatment and potential cerebral infarction or vascular disease.

Innovation Solution

A portable automated external defibrillator design featuring a body with a sub-power source, cable winding unit, and operation button, paired with an accessory containing a main power source and sub-controller, which prevents cable twisting and ensures stable power supply through a graphene storage battery, and is wearable for improved portability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the automated external defibrillator is made portable and wearable, then ease of operation and response time are improved, but the power supply capability deteriorates due to limited battery capacity in portable devices

Engineering Contradiction:
ImproveportabilityVSAvoidpower supply capability
Core Design Contradiction:
Ease of operationVSPower

Solution Approach 1:

The device is divided into two separate components: a wearable body unit with a small sub-power source for portability, and a separate accessory unit containing a large main power source. The cable connects these two units, allowing the user to wear the lightweight body while the accessory provides sufficient power for defibrillation when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A cable acts as an intermediary connector between the body unit and the accessory unit. This cable transmits both electrical power and control signals, enabling the small sub-power source in the wearable body to control the larger main power source in the separate accessory, thus resolving the power limitation of portable devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the electrode cable is made flexible for easy carrying, then ease of operation is improved, but the cable becomes susceptible to twisting and damage

Engineering Contradiction:
Improveease of carryingVSAvoidcable durability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cable is pre-wound around a winding unit integrated into the body unit before use. This preliminary winding action organizes the cable in a controlled manner, preventing random twisting and tangling during carrying and storage, thereby maintaining both flexibility and durability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cable is nested around the winding unit, which is integrated within the body unit structure. This nesting arrangement allows the cable to be compactly stored within the wearable device itself, protecting it from external damage while maintaining ease of carrying.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A portable automated external defibrillator includes a body and an accessory. The body includes a sub power source, a main controller, and a cable winding unit inside the body, an operation button on a front surface of the body, a main electrode pad on a rear surface of the body, and a plug on a side of the body and to which a cable wound on the cable winding unit is coupled. The accessory includes a main power source and a sub-controller inside the accessory, a sub-electrode pad on a rear surface of the accessory, and an outlet on a side of the accessory. The portable automated external defibrillator may prevent a cable of the electrode pad from being twisted or broken, and stably perform an electric shock by the main power source kept in an inactive state during carrying and which is activated in use.
