Solution Overview

Problem

Existing CPR devices are cumbersome, require assembly, and fail to provide effective chest compressions due to improper positioning and lack of adjustability, leading to delays and reduced effectiveness in administering CPR, especially by untrained bystanders.

Innovation Solution

A compact, foldable, and adjustable CPR positioning apparatus with an automated chest compression device mounted on a frame that can be quickly deployed around a patient, providing intuitive assembly and adjustable support for effective chest compressions regardless of patient position, allowing hands-free operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual CPR is performed by bystanders, then CPR can be administered, but physical exhaustion leads to inconsistent compressions and reduced effectiveness over time

Engineering Contradiction:
Improveautomated chest compressionVSAvoidmechanical CPR apparatus
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The mechanical CPR apparatus is designed to automatically perform chest compressions without requiring continuous manual operation. Once positioned and activated, the device self-regulates compression depth, rate, and rhythm, freeing the operator from physical exhaustion while maintaining consistent compression quality throughout the resuscitation process.

Inventive Principle:
Principle #25Self-service

2Reliability

If mechanical CPR apparatus is used, then compression consistency is improved, but apparatus assembly and positioning delay CPR initiation

Engineering Contradiction:
Improvecompression consistencyVSAvoidCPR initiation delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The apparatus is designed with pre-assembled components and intuitive positioning features that allow rapid deployment. The frame structure is configured to be quickly positioned around the patient's torso before CPR begins, with the chest compression device already in place and ready for immediate activation, eliminating assembly delays.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The apparatus incorporates adjustable and movable components that can be quickly configured to fit different patient sizes and positions. The frame and compression device can be dynamically adjusted during positioning to ensure proper alignment without requiring time-consuming assembly steps, enabling rapid deployment while maintaining compression reliability.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If fixed-position CPR devices are used, then device simplicity is maintained, but adaptability to different patient positions and sizes is reduced

Engineering Contradiction:
Improveadjustability to patient positionVSAvoidadjustable frame structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The apparatus features a dynamic frame structure with adjustable components that can be configured to accommodate various patient positions (supine, lateral, seated) and body sizes. The frame includes movable supports and adjustable compression device positioning that can be quickly modified during resuscitation to optimize CPR delivery for different clinical scenarios without requiring complete device reconfiguration.

Inventive Principle:
Principle #15Dynamics
