Solution Overview
Problem
Current teaching methods for congenital heart defects in nursing education, such as textbooks and 2D illustrations, fail to engage active learning and often confuse students due to anatomical complexity, while detailed 3D models can be distracting.
Innovation Solution
A cardiac defect model with interchangeable normal and defective cardiac component inserts, formed from 3D printing, featuring a base with cavities and protrusions for precise placement, allowing students to learn various heart defects methodically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If detailed 3D models are used to teach congenital heart defects, then anatomical accuracy and realism are improved, but student distraction and learning complexity increase
Solution Approach 1:
The heart model is divided into modular components that can be independently assembled and manipulated. Each component represents a specific anatomical structure or defect type, allowing students to focus on one element at a time rather than being overwhelmed by the complete detailed anatomy. This segmentation maintains anatomical accuracy while reducing cognitive overload and distraction.
Solution Approach 2:
Specific defective components are extracted from the complete heart model and placed in separate cavities for focused study. This allows students to examine particular congenital heart defects in isolation from the rest of the anatomy, improving understanding of specific pathologies without the distraction of complete anatomical detail.
2Ease of operation
If traditional teaching methods (textbooks, 2D illustrations) are used, then simplicity and ease of use are maintained, but student engagement and understanding of complex anatomy decrease
Solution Approach 1:
The teaching model transitions from two-dimensional illustrations to three-dimensional manipulable components. Students can physically assemble, disassemble, and rotate the heart model to view anatomical structures from multiple angles, providing comprehensive spatial understanding while maintaining ease of use through simple assembly operations.
Solution Approach 2:
The model uses simplified geometric shapes and standardized components that replicate essential anatomical features without requiring complete anatomical fidelity. This copying approach captures the critical structural relationships needed for learning while maintaining simplicity and ease of manipulation.
3Adaptability or versatility
If multiple cardiac defects are taught simultaneously using detailed models, then comprehensive coverage is improved, but learning retention and conceptual clarity decrease
Solution Approach 1:
Different congenital heart defects are represented as separate, interchangeable components that can be independently studied. Each defect type has its own dedicated cavity and component set, allowing students to master one defect type at a time while maintaining the ability to study multiple defects comprehensively by swapping components.
Solution Approach 2:
The base model serves multiple functions by accommodating various defect components in standardized cavities. The same base structure can display different congenital heart defects by simply changing the inserted components, providing comprehensive coverage of multiple defect types while maintaining a consistent, familiar framework that aids retention.

AI summary
A cardiac defect model that can be used for training and instruction purposes is provided. The cardiac defect model includes a base that includes an aorta, a pulmonary artery, a left atrium, a right atrium, a left ventricle, and a right ventricle. The cardiac defect model also includes a plurality of cavities. Each cavity is configured to receive a normal cardiac component insert and a defective cardiac component insert. Further, the normal cardiac component insert and the defective cardiac component insert are interchangeable.
