Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intravascular or percutaneous techniques are used to treat heart disorders, then surgery risk and recovery time are reduced, but device structure complexity increases significantly
Solution Approach 1:
The device is divided into multiple functional modules including a catheter delivery system, a transducer array with multiple elements, a control system, and a graphical interface system. Each module performs a specific function and can be independently controlled, reducing the overall complexity while maintaining the benefits of intravascular access.
Solution Approach 2:
A control system acts as an intermediary between the transducer array and the external graphical interface. This control system automatically selects and activates appropriate transducers based on pre-stored anatomical data and graphical path information, reducing the operational complexity for the physician while maintaining precise device control.
2Ease of operation
If intravascular or percutaneous techniques are used, then direct visual contact with devices is lost, but transducer selection and activation complexity increases
Solution Approach 1:
The system creates a graphical copy or representation of the transducer array's spatial arrangement and activates corresponding transducers based on pre-stored anatomical data and graphical path information. This graphical interface allows physicians to control transducers without direct visual contact, reducing operational complexity while maintaining precision.
Solution Approach 2:
The system incorporates feedback mechanisms where the control system receives input from the graphical interface, selects appropriate transducers based on pre-stored anatomical data, and activates them accordingly. This automated feedback loop reduces the complexity of transducer selection while maintaining precise control without direct visual contact.
3Adaptability or versatility
If multiple transducers are used for mapping and ablation functions, then treatment capability is enhanced, but device complexity increases
Solution Approach 1:
The transducer array is designed with multiple transducers that can perform multiple functions including mapping, sensing, and ablation. The control system automatically selects and activates the appropriate transducers based on the required function and pre-stored anatomical data, enabling enhanced treatment capability while managing device complexity through automated multi-functionality.
