Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional medical mannequins are used for CPR training, then training can be conducted with standard equipment, but the mannequins lack female anatomical representation leading to inadequate training for women
Solution Approach 1:
The breast simulation device is divided into separate components: a containment structure, fluid filling, and attachment mechanisms. This segmentation allows the device to be attached to conventional mannequins without replacing the entire mannequin system, thereby improving anatomical representation while maintaining simplicity.
Solution Approach 2:
The breast simulation device acts as an intermediary component that bridges conventional mannequins and female anatomical training requirements. By attaching the simulation device to the mannequin chest area, it provides female anatomical representation without requiring a completely new mannequin design.
2Adaptability or versatility
If breast simulation devices with fluid filling are used to simulate multiple breast sizes, then anatomical realism is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The device uses fluid filling to change the volume and shape parameters of the breast simulation. By adjusting the amount of fluid injected into the containment structure, different breast sizes can be simulated without manufacturing multiple devices with different fixed volumes, thereby improving versatility while maintaining ease of manufacture.
3Adaptability or versatility
If attachment devices are added to enable mounting on mannequins, then adaptability to training equipment is improved, but device complexity increases
Solution Approach 1:
The attachment device is designed with universal mounting capabilities that can be adapted to different mannequin types and chest configurations. The attachment mechanism uses general-purpose fastening methods that work across various mannequin designs, thereby improving compatibility without significantly increasing device complexity.

AI summary
Breast simulation devices and mannequin adapters. The breast simulation devices include a containment structure and a valve. The containment structure encloses an interior volume for holding a fluid, and the containment structure has a non-uniform thickness when viewed cross-sectionally. The valve is configured to (i) enable the fluid to be added to the interior volume and (ii) enable the fluid to be removed from interior volume. The mannequin adapters are configured to (i) be affixed to a medical mannequin and (ii) house one or more breast simulation devices.
