Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple rescuers perform CPR simultaneously without role identification, then CPR coverage is maintained, but feedback coordination becomes impossible and role transitions are not tracked

Engineering Contradiction:

ImproveCPR qualityVSAvoidrescuer role information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system provides real-time feedback to each rescuer by transmitting role identification results to portable computing devices, enabling coordinated feedback based on current roles while maintaining CPR quality

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Motion sensor data serves as an intermediary to indirectly identify rescuer roles without requiring direct communication or manual input from rescuers, resolving the information loss problem

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If manual role tracking is used among rescuers, then role information can be recorded, but response time during role transitions increases and coordination efficiency decreases

Engineering Contradiction:

Improverole transition speedVSAvoidrole transition time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system automatically identifies rescuer roles through motion sensors without requiring manual input or communication between rescuers, enabling instantaneous role detection and eliminating transition delays

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual role tracking is replaced with automated motion sensor-based identification, substituting mechanical human coordination with electronic detection and processing systems

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If general feedback is provided to all rescuers, then information distribution is simple, but feedback precision for specific roles (compression quality, ventilation timing) is insufficient

Engineering Contradiction:

Improvefeedback distributionVSAvoidfeedback accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

Feedback is customized according to each rescuer's identified role, with compression providers receiving depth and rate feedback while ventilation providers receive timing feedback, ensuring precision for specific roles

Inventive Principle:

Principle #3Local quality

4Measurement precision

If accelerometers are used to monitor compression depth, then compression quality can be measured, but the system cannot identify which rescuer is performing compressions or provide coordinated team feedback

Engineering Contradiction:

Improvecompression depth measurementVSAvoidrescuer identification information

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

Motion sensor data acts as an intermediary to identify which rescuer is performing compressions by analyzing characteristic motion patterns, preserving rescuer identification information while maintaining measurement precision

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces manual rescuer identification with automated motion pattern recognition, substituting mechanical observation with electronic sensor-based detection

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

In an illustrative embodiment, a system for collecting and presenting metrics related to each member of a team of rescuers involved in a resuscitation effort includes a set of wearable devices, each configured to determine role-identifying data indicative of a role of a rescuer donning the respective device. The system may include a portable computing device for storing, during the resuscitation effort, a time progression of compression data and ventilation data, receiving the role-identifying data from the wearable devices, and storing a time series of role information representing a series of changes in roles among the team of rescuers. The system may include a remote computing system for preparing a case overview GUI presenting time periods of compression data, each time period being visually correlated with a current rescuer and/or current wearable device corresponding to the compression role.
