Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CPR training systems lack effective feedback mechanisms, particularly for chest compressions and breathing techniques, as they often rely on non-sensor equipped manikins that cannot provide real-time performance evaluation, leading to inadequate training in adhering to established CPR guidelines.
Innovation Solution
A CPR training system comprising a manikin with a removable skin, a compression pad equipped with force and acceleration sensors, and a breathing module with an air pressure sensor, which processes signals to provide real-time feedback on compression depth, rate, and breathing volume, ensuring compliance with CPR guidelines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If non-sensor equipped manikins are used for CPR training, then the training system is simple and easy to operate, but real-time performance evaluation and feedback cannot be provided
Solution Approach 1:
The manikin is divided into functional modules: a removable skin layer, a compression pad with sensors, a breathing module with pressure sensors, and a control unit. This segmentation allows each component to be optimized independently while maintaining overall system functionality, resolving the contradiction between measurement capability and structural simplicity.
Solution Approach 2:
The system incorporates sensors that detect compression depth, rate, and breathing volume, then provide real-time feedback to users through visual and auditory signals. This feedback mechanism enables precise performance evaluation while keeping the manikin structure relatively simple through modular design.
2Measurement precision
If multiple sensors are integrated into the manikin to provide real-time feedback, then CPR performance can be accurately evaluated, but the device complexity and difficulty of installation increase
Solution Approach 1:
Sensors are grouped into functional modules (compression pad with force/acceleration sensors, breathing module with pressure sensors) that can be independently installed and replaced. The removable skin layer facilitates easy access to these modules, simplifying the installation process while maintaining comprehensive sensing capability.
Solution Approach 2:
The compression pad serves multiple functions: it detects compression depth through force sensors, measures compression rate through acceleration sensors, and provides tactile feedback to users. This multi-functionality reduces the need for separate components, simplifying installation while maintaining measurement precision.
3Speed
If acceleration sensors are used to detect compression depth in real-time, then feedback can be provided during training, but the correlation between acceleration signals and actual compression depth may be inaccurate
Solution Approach 1:
The system combines multiple sensing approaches: force sensors that directly measure compression depth, acceleration sensors that detect compression rate, and pressure sensors in the breathing module. By merging these sensing methods, the system achieves both real-time feedback and accurate measurement through data correlation and validation.
Solution Approach 2:
The control unit acts as an intermediary that processes signals from multiple sensors, correlates acceleration data with force sensor measurements, and validates breathing volume through pressure sensor feedback. This intermediary processing resolves the inaccuracy between acceleration signals and actual compression depth by cross-referencing multiple data sources.
4Ease of operation
If the skin is made removable to facilitate sensor installation, then the compression pad can be easily positioned, but the manikin structure becomes more complex
Solution Approach 1:
The manikin skin is designed as a removable layer that can be easily detached and reattached, providing access to the compression pad and breathing module for installation and maintenance. This segmentation adds minimal complexity while significantly improving ease of operation for sensor positioning.
Solution Approach 2:
The skin is constructed as a flexible, thin-film material that can be easily removed and reattached without compromising the structural integrity of the manikin. This approach provides easy access to internal components while maintaining a simple overall construction compared to rigid or permanently attached designs.

AI summary
A training system and training method for cardiopulmonary resuscitation (CPR) is disclosed. The training system includes a manikin, a chest compression module, a breathing module and a data processing module. The chest compression module and the breathing module are installed on the manikin and connected to the data processing module. During a training session, a student performs CPR on the manikin. The data processing module evaluates and provides feedback regarding the chest compressions and the rescue breathings performed by the student. The training method includes positioning the chest compression module and the breathing module on the manikin, initializing the chest compression module and the breathing module to identify compression and breathing characteristics of the manikin, performing CPR on the manikin, and evaluating the CPR based on the compression and breathing characteristics of the manikin.
