Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional CPR training mannequins are used, then the device structure is simple and cost-effective, but they fail to provide adequate feedback on proper technique and do not illustrate anatomical structures
Solution Approach 1:
The patent implements a feedback mechanism using a sensor to detect pressure applied to the mannequin's chest and lights to visually indicate whether the pressure is within the proper range. This provides real-time feedback to trainees on their CPR technique, resolving the information loss problem while adding only moderate complexity through the sensor-light system.
Solution Approach 2:
The patent uses color changes in the lights to convey different feedback states - lights illuminate in specific patterns or colors to indicate proper versus improper pressure application. This visual feedback method effectively communicates technique quality without requiring complex display systems.
2Loss of information
If traditional CPR training mannequins are used, then the device is simple to manufacture, but they fail to provide visualization of anatomical structures and their functions
Solution Approach 1:
The patent incorporates lights within the mannequin's anatomical structures (such as the heart and carotid artery) that illuminate to show blood flow and anatomical function during CPR. This visualizes the complex interrelated functions and structures of the human body pertinent to CPR without requiring complex external display systems.
Solution Approach 2:
The patent uses lights as an intermediary to make invisible anatomical processes visible. The lights mediate between the internal physiological processes (blood flow, heart function) and the trainee's observation, allowing visualization of anatomical structures and their functions during CPR administration.
3Reliability
If pressure sensing and illumination systems are added to the mannequin, then feedback on proper technique is provided, but the device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism using a sensor to detect pressure applied to the mannequin's chest and lights to visually indicate whether the pressure is within the proper range. This provides real-time feedback to trainees on their CPR technique, resolving the information loss problem while adding only moderate complexity through the sensor-light system.
Solution Approach 2:
The mannequin serves itself by automatically detecting pressure through the sensor and providing appropriate visual feedback through the light system without requiring external monitoring or intervention. This self-service capability improves training reliability while minimizing the need for additional complex control systems.

Implementation Method 1
A sensor disposed about the mannequin is configured to detect pressure being applied to the simulated heart and torso section
Implementation Method 2
The sensor is operably connected to a simulated carotid artery having a plurality of lights at intervals, the plurality of lights being configured to illuminate in response to the sensor detecting a first pressure

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 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.
