Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real patients are used for training healthcare students, then the authenticity of training is improved, but patient comfort and privacy deteriorate due to repeated examinations
Solution Approach 1:
The patent creates a pulsation generator that replicates the pulse generation function of a human heart. The device uses a diaphragm, chamber, and valve system to generate pulsations that mimic cardiac output, providing a realistic training model without using actual patients. This copying approach maintains training authenticity while eliminating harm to patients.
Solution Approach 2:
The pulsation generator acts as an intermediary between the training objective and the student. Instead of directly examining patients, students interact with the pulsation generator that mediates the pulse sensation. This intermediary device provides the necessary tactile feedback for learning while protecting patients from repeated examinations.
2Adaptability or versatility
If real patients with various health disorders are arranged for training, then the diversity of training cases is improved, but the availability and logistics deteriorate
Solution Approach 1:
The pulsation generator is designed with adjustable parameters including pulse rate, pulse pressure, and stroke volume. These dynamic adjustments allow the device to simulate various cardiac conditions and health disorders, providing training case diversity without the logistical challenges of arranging different patients. The device can be reconfigured instantly to represent different clinical scenarios.
Solution Approach 2:
The patent employs parameter changes to create diverse training scenarios. By modifying the pulse rate, pressure, and volume parameters of the pulsation generator, the same physical device can represent multiple different cardiac conditions. This approach provides versatility while maintaining ease of operation, as parameter adjustment is simpler than patient scheduling and coordination.

AI summary
A simulator for simulating a pulse in a manikin comprises a manikin body. The simulator further comprises a first magnet and a second magnet disposed opposite to each other and spaced apart from each other. The first magnet and second magnet comprise two juxtaposed first and second sub-magnets. The first and second juxtaposed sub-magnets in each magnet are oriented substantially in opposite directions. The first magnet and the second magnet are positioned such that the first sub-magnet of the first magnet is oriented substantially in a same direction as the first sub-magnet of the second magnet and such that the second sub-magnet of the first magnet is oriented substantially in a same direction as the second sub-magnet of the second magnet. The transducer further comprises an armature movably disposed between the first and second magnets. The armature comprises a frame and a solenoid wound adjacent a periphery of the frame. The transducer also comprises a rod attached to the frame of the armature. The armature interacts with the manikin body to simulate the pulse.
