Solution Overview

Problem

Current heart massage equipment lacks precise guidance for correct pressure placement and frequency, leading to inefficiency in CPR and a risk of rib damage, as it does not accurately conform to the anatomy of the breastbone and heel of the hand, and lacks feedback mechanisms for optimal compression.

Innovation Solution

A heart massage device with a resilient, anatomically shaped plate that distributes pressure evenly, embedded sensors for pressure and frequency feedback, and a hand strap for secure positioning, combined with visual and auditory indicators to ensure correct compression depth and rate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a flat compression surface is used, then the device is simple to manufacture, but the pressure is not correctly distributed across the chest leading to rib damage

Engineering Contradiction:

Improveease of manufactureVSAvoidrib damage

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The compression surface is shaped to correspond to the anatomy of the breastbone and heel of hand, replacing a flat surface with a curved, anatomically-contoured surface that distributes pressure correctly across the chest while preventing rib damage

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Device complexity

If no feedback mechanism is provided, then the device is simpler, but the correct pressure and frequency cannot be ensured

Engineering Contradiction:

Improvedevice complexityVSAvoidpressure measurement

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

Pressure sensors are embedded in the compression surface to detect compression depth and frequency, providing real-time feedback through visual and auditory indicators to ensure correct CPR parameters are maintained

Inventive Principle:

Principle #23Feedback

3Device complexity

If the equipment does not conform to anatomy, then the device is simpler to design, but correct placement is difficult achieving

Engineering Contradiction:

Improvedevice complexityVSAvoidease of placement

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The plate is shaped to correspond to the anatomy of the breastbone and heel of hand, creating complementary curved surfaces that guide correct placement through anatomical conformity rather than complex adjustment mechanisms

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

By using a plate (1) according to the invention as a pad of a helper's hand when the helper is to give heart massage (CPR) and to shape the top side (3) of the plate (1) into the shape of the heel of the hand (6) and its bottom side (11) into the shape of the chest (12), a correct arrangement of the plate on the chest (12) will be ensured. The plate (1) is provided with embedded sensors (2) such that the compressive force as well as the pressure frequency may be registered and indicated for controlling and ensuring correct massage.
