Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different pulse sequences are generated by manual activation of program units, then pulse sequence functionality is provided, but the configuration is fixed and unclear to operators
Solution Approach 1:
The pulse sequence is divided into modular program units that can be independently configured and combined. Each program unit represents a discrete functional block that can be selected and arranged to create different pulse sequences, making the system both versatile and easier to operate through modular design
Solution Approach 2:
The system transitions from fixed, hard-coded pulse sequences to a dynamic configuration system where program units can be selectively activated and reconfigured. This allows the pulse sequence structure to adapt dynamically based on operator selection and imaging requirements
2Stability of the object's composition
If program units are combined in fixed order, then pulse sequence structure is maintained, but modification and selection of desired sequences is difficult
Solution Approach 1:
By segmenting the pulse sequence into independent program units with defined interfaces, the system maintains structural integrity through standardized connections while allowing flexible reconfiguration of individual units. This modular architecture enables both structural stability and adaptability
Solution Approach 2:
The system allows modification of pulse sequences by changing parameters such as the selection, ordering, and configuration of program units. This enables versatile sequence customization while maintaining the overall structural framework through controlled parameter adjustments
3Adaptability or versatility
If a mediator unit is introduced to exchange information between program units, then dynamic and flexible design is enabled, but device complexity increases
Solution Approach 1:
The mediator unit serves multiple functions: it manages information exchange between program units, maintains data consistency, handles configuration requests, and coordinates pulse sequence execution. This multi-functionality justifies the added component by consolidating several control tasks into a single versatile unit
Solution Approach 2:
The mediator unit acts as an intermediary layer between program units, standardizing communication interfaces and managing data flow. This abstraction layer simplifies the overall system architecture by providing a uniform interface pattern, reducing the complexity of direct peer-to-peer connections between multiple program units
4Adaptability or versatility
If manual activation of program units is used, then pulse sequence selection is possible, but the process is time-consuming and inefficient
Solution Approach 1:
The system enables automated configuration of pulse sequences through pre-defined program unit combinations and selection mechanisms. Operators can quickly select desired sequences without manual activation of each program unit, allowing the system to serve itself in terms of configuration assembly while maintaining adaptability
