Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If microwave generators incorporate additional features such as temperature measurement devices or microwave signal measurement devices, then the functionality and utility of the system is improved, but the device complexity and difficulty of updating reconfiguring increases
Solution Approach 1:
The microwave generator is divided into a base unit and separate auxiliary modules. Each auxiliary module (temperature measurement device, microwave signal measurement device, etc.) functions independently and can be selectively connected to the base unit. This segmentation allows users to add only the necessary features for specific procedures without permanently increasing the complexity of the entire system.
Solution Approach 2:
The system transitions from a static, fixed configuration to a dynamic, reconfigurable architecture. Auxiliary modules can be connected and disconnected based on procedural needs, and the base unit can be updated with new features while maintaining compatibility with existing modules. This dynamic structure enables continuous adaptation to new technologies and procedures.
2Adaptability or versatility
If microwave generators include built-in additional features, then the system provides comprehensive functionality, but the ease of updating and reconfiguring to meet changing needs deteriorates
Solution Approach 1:
By separating auxiliary features into independent modules, the system enables selective replacement and updating of individual modules without affecting the base unit or other modules. This modular approach simplifies the update process compared to replacing an entire built-in system.
Solution Approach 2:
The base unit is designed with universal interfaces and communication protocols that can accommodate various types of auxiliary modules. This universality allows the base unit to work with multiple generations of modules, facilitating easy updates while maintaining comprehensive functionality.
3Reliability
If microwave generators are designed as integrated systems, then the system provides stable and reliable operation, but the flexibility to customize and select only necessary functionalities is reduced
Solution Approach 1:
The system maintains reliability through standardized interfaces and communication protocols between the base unit and auxiliary modules. Each module operates independently with its own power supply and processing, ensuring that failures in one module do not affect the stability of the entire system, while still providing customized functionality.
4Adaptability or versatility
If all auxiliary modules are always connected to the microwave generator, then the system is ready for any procedure, but the power consumption and energy usage increases
Solution Approach 1:
The system dynamically adjusts its configuration by connecting only the necessary auxiliary modules for each specific procedure. The base unit can be quickly reconfigured by connecting or disconnecting modules based on the procedural requirements, ensuring optimal power consumption while maintaining system readiness for various procedures.
