Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual CPR operation is used, then operators can perform CPR, but it requires professional medical skills and high accuracy which are hard to find in emergencies

Engineering Contradiction:

Improveease of operationVSAvoidquality of CPR

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs self-diagnosis and self-adjustment by automatically analyzing ECG signals and adjusting CPR parameters without requiring external medical expertise. The device serves itself by making intelligent decisions based on real-time physiological data.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical CPR operation with an automated system that uses sensors, processors, and algorithms to perform CPR. The mechanical action of compression is supplemented or replaced by intelligent control systems that adjust force and frequency automatically.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Duration of action of stationary object

If automatic CPR devices are used, then operation continuity is improved, but they lack intelligent judgment mechanisms to adjust force and frequency according to patient conditions

Engineering Contradiction:

Improvecontinuity of CPRVSAvoidability to adjust to patient conditions

Core Design Contradiction:

Duration of action of stationary objectVSAdaptability or versatility

Solution Approach 1:

The system continuously monitors ECG signals and uses this feedback to automatically adjust CPR parameters. The feedback loop includes sensing heart rhythm, analyzing it through algorithms, and modifying compression force and frequency in real-time based on the analyzed data.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent implements dynamic adjustment of CPR parameters where force and frequency are not fixed but continuously adapted based on real-time ECG analysis. The system transitions from static automatic CPR to dynamic intelligent CPR that responds to changing patient conditions.

Inventive Principle:

Principle #15Dynamics

3Measurement precision

If conventional ECG signal analysis is used, then heart conditions can be assessed, but it relies on subjective judgment and may not be handled in time

Engineering Contradiction:

Improveaccuracy of heart condition assessmentVSAvoidtime to analyze ECG signals

Core Design Contradiction:
