Solution Overview

Problem

Manual CPR can be ineffective due to incorrect positioning of mechanical CPR devices, leading to delays in chest compressions and potential irreversible damage to vital organs, especially in emergency situations where rescuers may struggle to align the device correctly.

Innovation Solution

The use of alignment devices, such as sensors, straps, templates, and light-emitting devices, to ensure accurate positioning of the backboard and upper portion of mechanical CPR devices, providing real-time feedback to rescuers through visual or auditory cues, and the option of using a mechanical CPR device without a backboard to eliminate positioning complications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual CPR is performed by untrained rescuers, then the device is simple to operate, but the positioning accuracy and effectiveness of chest compressions deteriorate

Engineering Contradiction:

Improveease of operationVSAvoidpositioning accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

Visual alignment aids (colored stripes, markers, templates) serve as intermediaries between the rescuer and the patient's anatomy, providing clear guidance for correct backboard positioning without requiring advanced training. The alignment device mediates the positioning process by translating complex anatomical landmarks into simple visual cues

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Color-coded alignment indicators (e.g., colored stripes on the backboard matching colored markers on the patient) provide immediate visual feedback for correct positioning. The color matching system allows rescuers to quickly identify proper alignment through simple color correspondence rather than requiring knowledge of anatomical landmarks

Inventive Principle:

Principle #32Color changes

2Device complexity

If the backboard is positioned first before attaching the upper portion, then the device structure is simplified, but the alignment time and setup duration increase

Engineering Contradiction:

Improvedevice structureVSAvoidalignment time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The backboard is pre-positioned on the patient's back with alignment markers visible before the upper portion of the mechanical CPR device is attached. This preliminary positioning with visual guides prepared in advance allows for rapid verification of correct alignment, reducing the time needed during the actual device assembly and activation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Visual feedback mechanisms (alignment markers, colored stripes, templates) provide real-time confirmation of correct backboard positioning. The feedback system allows rescuers to immediately verify proper alignment without trial-and-error adjustments, reducing iterative repositioning time while maintaining simplified device structure

Inventive Principle:

Principle #23Feedback

3Measurement precision

If alignment devices with multiple components are used, then the positioning precision is improved, but the device complexity and setup time increase

Engineering Contradiction:

Improvepositioning precisionVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

Multiple alignment functions (backboard positioning, upper portion alignment, compression point identification) are merged into integrated visual guidance systems. The alignment markers and colored indicators serve multiple purposes simultaneously, providing comprehensive positioning guidance without requiring separate complex alignment devices for each function

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The alignment device components are designed to serve multiple functions: the colored stripes and markers not only guide backboard positioning but also verify upper portion alignment and confirm compression point accuracy. This multi-functionality achieves high positioning precision without proportionally increasing device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An alignment device for assisting a rescuer for correctly aligning a mechanical cardiopulmonary resuscitation (CPR) device. The alignment device can guide positioning of the backboard so that the backboard is correctly positioned prior to connecting an upper portion of the mechanical CPR device to the backboard. The alignment device can also include positioning the mechanical CPR device without a backboard or positioning the backboard and the upper portion of the mechanical CPR device nearly simultaneously.
