Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical training manikins lack realism, durability, and ease of use, and are not designed for efficient transportation and storage, while also being cost-effective and capable of simulating human anatomy accurately.
Innovation Solution
A portable CPR manikin kit comprising a stackable torso with slotted openings for realistic chest compression, a two-part head with tiltable feature, and an electro-mechanical indicator for real-time feedback, along with a chest compression piston that provides resistance through a quick release mechanism and large spring, allowing for compact storage and realistic simulation of human anatomy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the manikin uses a rigid frame structure to provide durability and realistic simulation, then the simulation realism is improved, but the weight increases and portability decreases
Solution Approach 1:
The manikin is divided into multiple detachable components including torso, head, limbs, and base sections that can be separated for transport and reassembled for use. This segmentation allows each component to be lightweight while the assembled structure provides realistic simulation capabilities.
Solution Approach 2:
The manikin uses flexible synthetic skin coverings and pliable material layers instead of rigid external frames. These flexible shells provide realistic tactile feedback and visual appearance while maintaining lightweight construction and portability.
2Reliability
If the manikin is designed as a single integrated unit for realistic simulation, then the simulation quality is improved, but the ease of transportation and storage decreases
Solution Approach 1:
The integrated manikin is segmented into modular components that can be detached and stored separately or stacked compactly. This allows high-quality simulation when assembled while enabling easy transport and space-efficient storage when disassembled.
Solution Approach 2:
Smaller manikin components such as limbs and head can be nested within or attached to larger components like the torso during storage, creating a compact configuration that is easy to transport while maintaining the ability to assemble into a complete realistic simulation model.
3Duration of action of stationary object
If the manikin uses heavy durable materials for longevity, then the product life is improved, but the portability and ease of handling decreases
Solution Approach 1:
The manikin combines lightweight materials such as foams, plastics, and synthetic fabrics with strategically placed reinforcement elements. This composite construction provides durability and extended product life while maintaining overall lightweight construction for easy portability.
Solution Approach 2:
Durable flexible synthetic materials are used for the skin covering and structural components, providing longevity and resistance to wear while remaining lightweight and easy to handle during transport and setup.
4Reliability
If the manikin includes complex anatomical features for realistic simulation, then the training effectiveness is improved, but the device complexity and cost increases
Solution Approach 1:
Complex anatomical features such as articulated joints, flexible rib cages, and realistic tissue layers are concentrated in specific critical areas like the chest and head where they provide maximum training value, while other areas use simpler constructions to control overall complexity and cost.
Solution Approach 2:
Flexible synthetic skin and tissue-like materials are used to create realistic anatomical appearances and tactile feedback without requiring complex internal structures, achieving training effectiveness while controlling device complexity.

AI summary
A portable medical training manikin with a hollow torso body with a chest plate having slotted openings provided to enable realistic flexing of the chest plate along hinges engaged with a chest compression piston. The torso body has a realistic skin covering the torso and interconnected at a hinge. A chest compression piston supports and resists chest compressions performed by a user. The chest compression piston is engaged with the central chest plate of the torso body by a quick release mechanism having detent locks for securing the piston engaged with the chest plate. A two-piece tiltable head configuration enables detachment of the back half of the head piece, and inversion for nested stacking within the front half head piece. The hollow torso body is likewise configured for convenient stacking, including the compression pistons, in a carrying container.
