Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional EKG training methods are used, then learners can access basic EKG rhythm information, but learners cannot effectively integrate new information with existing anatomical and physiological knowledge
Solution Approach 1:
The patent creates a physical replica of the human heart with transparent chambers and walls that copies anatomical structures. This replica integrates EKG rhythm information with visual anatomical representation, allowing learners to see the connection between electrical activity and heart structure simultaneously, thereby effectively integrating new information with existing anatomical knowledge
Solution Approach 2:
The patent introduces an intermediary system consisting of LED lights embedded in the heart replica that visually represent electrical activity. This intermediary translates abstract EKG concepts into visible anatomical processes, serving as a bridge between new EKG information and existing anatomical understanding
2Adaptability or versatility
If heart rate is increased to simulate tachyarrhythmia, then more realistic cardiac conditions are demonstrated, but individual waves become difficult to identify due to overlap
Solution Approach 1:
The patent implements a pace control button that dynamically adjusts the heart rate simulation. Learners can control the tempo of electrical activity visualization, slowing it down to clearly observe individual waves when studying normal rhythm, and speeding it up to simulate tachyarrhythmia conditions when needed, thereby maintaining wave identification accuracy across different heart rate simulations
Solution Approach 2:
The patent changes the temporal parameter of electrical activity visualization through the pace control mechanism. By adjusting the timing and speed of LED illumination sequences, the system maintains clear wave separation even when simulating faster heart rates, allowing learners to observe wave morphology accurately across different cardiac conditions
3Manufacturing precision
If detailed anatomical structures are included in the heart replica, then anatomical accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by making specific portions of the heart replica transparent (chambers and walls) while keeping other parts opaque or simplified. This selective transparency allows detailed visualization of electrical activity in critical areas without requiring the entire replica to be complex and transparent, thereby reducing overall device complexity while maintaining anatomical accuracy where needed
