Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate TTFields devices are used to treat multiple tumors, then each tumor can receive appropriate treatment, but the device complexity and number of components increase significantly
Solution Approach 1:
The system divides the treatment function into independently controllable electrode elements (master and slave electrodes) that can be selectively activated. Each electrode element can be independently programmed with specific frequencies and firing configurations, allowing targeted treatment of multiple tumors using a single integrated device rather than multiple separate devices.
Solution Approach 2:
The TTFields device is designed with universal functionality to treat multiple tumors simultaneously or sequentially. The control device can dynamically program frequency ranges and firing sequences for multiple electrode elements, enabling one device to perform the function of multiple separate devices through software-controlled configuration.
2Adaptability or versatility
If multiple separate TTFields devices are used for multiple tumors, then each tumor receives dedicated treatment, but the treatment cost increases
Solution Approach 1:
The patent merges multiple treatment functions into a single TTFields device. By combining multiple master and slave electrode elements in one device with a unified control system, the invention eliminates the need for multiple separate devices, thereby reducing the quantity of equipment required and associated costs while maintaining the ability to treat multiple tumors.
Solution Approach 2:
The device achieves multi-tumor treatment capability through universal programming of electrode elements. The control device can configure different frequency ranges and firing sequences for different electrode pairs, allowing one device to replace multiple specialized devices through software-defined treatment protocols.
3Adaptability or versatility
If multiple separate TTFields devices are used, then comprehensive tumor coverage is achieved, but the programming and operational complexity increases
Solution Approach 1:
The control device automatically manages the complexity of programming multiple electrode elements. The system can dynamically program frequency ranges and firing sequences without requiring manual configuration of each electrode, reducing operational complexity. The device serves itself by internally coordinating the multiple electrode elements under unified control.
Solution Approach 2:
The control device acts as an intermediary between the operator and the multiple electrode elements. It abstracts the complexity of programming by providing a unified interface that manages frequency ranges, firing configurations, and sequences for all electrode elements, shielding the user from the underlying complexity while maintaining comprehensive treatment coverage.
