Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mannequins for cardiopulmonary resuscitation training lack accuracy in detecting the depth and rate of chest compressions, leading to inconsistent training quality due to reliance on sound feedback which can degrade over time.
Innovation Solution
A mannequin with a pivoting arm equipped with a magnet and sensors that detect the magnetic force at different heights, providing real-time feedback on compression depth and rate through a display, ensuring accurate training by determining the correct depth and frequency of cardiac compressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sound feedback is used to indicate successful cardiopulmonary resuscitation training, then the device complexity is reduced, but the measurement precision of compression depth and rate degrades over time
Solution Approach 1:
The patent replaces the mechanical sound feedback system with a magnetic sensing system. Magnets are embedded in the pivoting arm at multiple positions, and magnetic sensors detect the position of these magnets to determine compression depth and rate. This substitution eliminates the degradation issue of mechanical components while maintaining relatively simple device architecture.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the mechanical compression action and the electronic detection system. The magnets attached to the pivoting arm create magnetic fields that are detected by magnetic sensors, providing a non-contact measurement method that avoids mechanical wear and maintains precision over time.
2Measurement precision
If multiple sensors are installed to detect compression depth and rate accurately, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent makes the pivoting arm multi-functional by embedding multiple magnets in it. This single component serves both as the mechanical lever for compression and as the carrier for multiple magnetic position indicators. The magnetic sensors detect different magnet positions to simultaneously determine both compression depth and rate, reducing overall system complexity.
Solution Approach 2:
The patent merges the mechanical structure (pivoting arm) with the sensing target (magnets). Instead of having separate mechanical components and separate sensing components, the magnets are integrated into the pivoting arm itself, combining structural and sensing functions into a unified system that reduces complexity.
