Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single controller coordinates all components in a biological fluid treatment device, then device complexity is reduced, but reliability and security are compromised due to potential single points of failure and hacking threats
Solution Approach 1:
The controller architecture is segmented into a first controller for user input and a second controller for component coordination. This segmentation eliminates single points of failure and prevents external hacking threats from compromising the entire system, as each controller operates independently with specific functions.
Solution Approach 2:
A separate communications protocol acts as an intermediary layer between the two controllers and between controllers and components. This intermediary ensures secure and reliable coordination while maintaining architectural simplicity, as the protocol standardizes interactions without requiring complex point-to-point integration.
2Reliability
If multiple controllers are used to improve security and reliability, then system coordination is enhanced, but device complexity and cost increase
Solution Approach 1:
The system is divided into two functional controllers with clearly defined responsibilities: the first controller handles user input and interface operations, while the second controller manages component coordination and treatment processes. This segmentation improves reliability without creating excessive complexity.
Solution Approach 2:
Each controller is designed to handle multiple functions within its domain. The first controller manages various user interface functions, while the second controller coordinates multiple treatment components. This multi-functionality reduces the need for additional specialized controllers, thereby limiting complexity growth.
3Device complexity
If a unified communication protocol is used across all components, then device complexity is minimized, but security vulnerabilities increase due to potential external hacking threats
Solution Approach 1:
A separate communications protocol serves as an intermediary security layer between controllers and external systems. This protocol implements security measures while maintaining standardized communication, thereby protecting against hacking threats without requiring complex custom protocols for each component.
Solution Approach 2:
The communication architecture is segmented into different protocol layers: a first communications protocol for user input and a second communications protocol for component coordination. This segmentation isolates security-critical communications from user-facing interfaces, limiting the impact of potential security breaches.
4Productivity
If components are modified or replaced to improve performance, then productivity is enhanced, but regulatory compliance becomes more difficult due to impact on other components
Solution Approach 1:
The device architecture is segmented into modular components controlled by distinct controllers. This allows individual components to be modified or replaced for improved productivity without requiring revalidation of the entire system, as each controller-managed module can be independently assessed for regulatory compliance.
Solution Approach 2:
The standardized communications protocols provide universal interfaces that remain consistent even when components are modified. This universality maintains regulatory compliance by ensuring that communication standards and safety protocols remain unchanged, allowing component improvements without system-wide revalidation.
