Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable defibrillation devices face challenges in ensuring timely and reliable application of conductive paste for effective defibrillation, due to high contact resistance issues and the unreliability of gas-explosion mechanisms for paste release.
Innovation Solution
The electrode plate features a hermetic shell with an inflation port and an overflow aperture, housing a capsule with a conductive paste. A sealing structure, comprising a sealing component and a force applying component, automatically opens the overflow aperture upon inflation, allowing the conductive paste to be reliably and safely applied to the patient's skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas-producing agent is used to create high gas pressure to break open the capsule and release conductive paste, then the conductive paste can be released, but the box must have thick and hard walls causing discomfort to the patient
Solution Approach 1:
The device is divided into separate functional components: a soft wearable box for comfort, a separate capsule for paste storage, and a membrane with aperture for controlled release. This segmentation allows each component to be optimized independently - the box remains soft and comfortable while the capsule provides reliable paste release when needed.
Solution Approach 2:
A membrane with aperture serves as an intermediary between the capsule and the external environment. The membrane allows controlled release of conductive paste through the aperture when gas pressure is applied, while the gas itself acts as an intermediary to transmit force from the power source to the capsule without requiring the box walls to be thick and hard.
2Reliability
If gas-producing agent explosion is used to release conductive paste, then paste release can be achieved, but safety of the gas-producing agent becomes difficult to guarantee
Solution Approach 1:
The invention uses a disposable electrode plate with integrated capsule and membrane that is replaced after use. This eliminates the need for reusable gas-producing agents and complex safety mechanisms, as the entire assembly is discarded after a single use, ensuring safety without compromising paste release reliability.
Solution Approach 2:
Gas from a power source acts as an intermediary to inflate the electrode plate and apply pressure to the capsule, causing the membrane to rupture and release the paste. This intermediary gas mechanism avoids direct use of explosive gas-producing agents while achieving the same paste release effect with improved safety.
3Quantity of substance
If multiple capsules are used with gas-producing agent, then sufficient paste can be released, but strength differences between capsules cause individual capsules to break open prematurely
Solution Approach 1:
The gas-producing agent is extracted and separated from the electrode plate assembly, placed instead in a power source that inflates the plate. This externalization allows uniform pressure application to all capsules simultaneously through the inflated plate, eliminating the problem of premature rupture caused by localized pressure variations from internally placed agents.
Solution Approach 2:
The inflated electrode plate acts as an intermediary that distributes pressure uniformly across multiple capsules. When the plate is inflated by gas from the power source, it applies even pressure to all capsules simultaneously, ensuring they all rupture at the same time and release paste consistently, regardless of minor strength differences between capsules.

AI summary
An electrode plate (100) and a wearable defibrillation device are disclosed. The electrode plate (100) includes a hermetic shell (110), a capsule (120) and a sealing structure (130). The hermetic shell (110) has an inflation port (111) and an overflow aperture (112). The overflow aperture (112) is disposed in a conductive exposed surface (113) of the hermetic shell (110). The capsule (120) is provided in the hermetic shell (110) and defines a cavity (122) for storage of a conductive paste therein. The cavity (122) defines an inlet orifice (123) and an outlet orifice (124). The overflow aperture (112) is disposed at the outlet orifice (124). A sealing component (132) of the sealing structure (130) is positioned at the overflow aperture (112) and configured to close the overflow aperture (112) and the outlet orifice (124) when the hermetic shell (110) is not inflated. The force applying component (131) of the sealing structure (130) is disposed on the hermetic shell (110) and then is connected to the sealing component (132) after being inserted into the capsule (120) through the inlet orifice (123). The force applying component (131) is configured to pull the sealing component (132) as a result of inflation and expansion of the hermetic shell (110) and thus open the overflow aperture (112) and the outlet orifice (124) and bring them into communication. As a result, the conductive paste is allowed to flow through the outlet orifice (124) and the overflow aperture (112) onto the exposed surface (113). During cardiac defibrillation of the electrode plate (100), the conductive paste can automatically applied to provide a patient with timely protection, and the conductive paste can be released in a reliable and safe manner.
