Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional CPR training mannequins are used, then the device is simple and easy to manufacture, but they fail to provide adequate feedback on proper CPR technique and do not illustrate human body structures
Solution Approach 1:
The patent implements a feedback mechanism using pressure sensors that detect compression depth and rate, coupled with visual indicators (lights) that provide real-time feedback to the trainee. This resolves the contradiction by adding information feedback while managing device complexity through integrated sensor-indicator systems.
Solution Approach 2:
The patent introduces an intermediary feedback system consisting of sensors and visual indicators that mediate between the trainee's actions and the training objective. This intermediary layer provides the necessary information without requiring direct complex measurement systems.
2Loss of information
If traditional CPR training mannequins are used, then the device is simple in design, but they fail to provide visualization of human body structures relevant to CPR
Solution Approach 1:
The patent uses visual indicators as intermediaries to represent internal body structures and physiological responses. Instead of requiring complex transparent anatomical models, simple light indicators serve as intermediaries to convey information about heart activity, blood flow, and compression effectiveness.
Solution Approach 2:
The patent creates simplified copies or representations of internal body structures using visual indicators rather than detailed anatomical models. This allows visualization of relevant structures without the complexity of full anatomical replication.
3Reliability
If pressure sensors and visual indicators are added to provide feedback, then proper CPR technique can be indicated, but the device complexity increases
Solution Approach 1:
The patent implements a feedback loop where sensors detect compression parameters and visual indicators provide immediate feedback. This resolves the reliability-complexity contradiction by using a direct sensor-indicator connection that provides reliable technique indication with minimal intermediary components.
Solution Approach 2:
The feedback system is designed to be self-regulating, where the sensors automatically detect compression depth and rate, and the visual indicators automatically provide feedback without requiring external intervention or complex processing systems.
4Loss of information
If the mannequin includes transparent sections to show anatomical structures, then CPR-relevant body structures can be viewed, but manufacturing complexity increases
Solution Approach 1:
Instead of manufacturing complex transparent anatomical models, the patent uses simple transparent sections combined with visual indicators that copy or represent the essential anatomical structures and physiological responses. This reduces manufacturing complexity while maintaining visualization functionality.

AI summary
A CPR patient training mannequin. The CPR patient training mannequin provides for training and teaching individuals in proper CPR technique. The mannequin includes a simulated torso section and simulated head section that enables a user to administer CPR and visually inspect the mannequin's response to the administration. The torso section utilizes a sensor configured to detect pressure exerted by a user performing chest compressions and includes one or more lights positioned in a simulated carotid artery and brain that are operably connected to the sensor. The lights are configured to illuminate to indicate the pressure exerted by a user. In an alternative embodiment, the torso section includes simulated lungs having lights that illuminate if a user properly performs a jaw-thrust maneuver and nose pinch on the mannequin.
