Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If fixed predetermined contact areas are used for electrode positioning, then the simulator structure is simplified, but realism and adaptability are reduced

Engineering Contradiction:

Improvesimulator structureVSAvoidelectrode positioning flexibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The simulator surface is segmented into multiple zones with different electrical properties (conductive and insulating areas), allowing electrodes to be placed on conductive zones while maintaining realistic anatomical representation. This segmentation enables flexible electrode positioning without requiring a completely complex redesign of the entire simulator structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The simulator is designed to work with any defibrillator device type (manual, automated, AED) through universal electrode covers that interface with standard defibrillator electrodes. The same simulator surface can accommodate different electrode placements for various training scenarios, providing multi-functionality without increasing structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If specifically configured mannequins with embedded electrical circuits are used, then the electrical discharge can be collected, but the risk of electrical shocks and electronic interferences increases

Engineering Contradiction:

Improveelectrical discharge collectionVSAvoidrisk of electrical shocks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

An impedance circuit acts as an intermediary between the defibrillator electrodes and the simulator body. This intermediary circuit safely manages the electrical discharge by providing controlled impedance matching, preventing direct high-voltage exposure to the simulator's electronic components and reducing the risk of electrical shocks and interference.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The simulator uses a simplified electrical model that copies only the essential characteristics of human tissue impedance needed for training purposes, rather than embedding complex biological systems. This copying approach maintains reliability for discharge collection while minimizing harmful electrical effects by avoiding unnecessary electronic components.

Inventive Principle:

Principle #26Copying

3Ease of manufacture

If visible contact areas and predetermined positions are used, then manufacturing is simplified, but realism is reduced

Engineering Contradiction:

Improvesimulator productionVSAvoidanatomical simulation realism

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

Different regions of the simulator surface are given different electrical properties (conductive vs. insulating) to match anatomical variations. This local quality differentiation allows realistic simulation of different body parts and anatomical characteristics while maintaining a relatively simple overall manufacturing process using standard materials and techniques.

Inventive Principle:
