Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple single-function controllers are installed to provide multiple functions, then the system can achieve required functionality, but the device complexity and operational complexity increase
Solution Approach 1:
The controller is designed to perform multiple functions including leak detection using capacitive sensors, level control using ultrasonic sensors, rate and count control through solenoid valve management, and pressure monitoring. This multi-functional integration eliminates the need for multiple separate controllers while maintaining all required capabilities.
2Adaptability or versatility
If multiple single-function controllers are installed to provide multiple functions, then the system can achieve required functionality, but the ease of operation deteriorates due to multiple alarm locations and indications
Solution Approach 1:
All alarm indications and diagnostic information are merged into a single display unit on the controller. The display shows alarm conditions, sensor status, and system state in one location, eliminating the need for operators to check multiple separate alarm locations and indications across different controllers.
3Reliability
If a single-use controller is used for a specific function, then the controller can be optimized for that function, but the adaptability to perform other functions is limited
Solution Approach 1:
The controller integrates multiple sensing capabilities (capacitive sensors for leak detection, ultrasonic sensors for level control), actuation control (solenoid valve management for rate and count control), and monitoring functions (pressure sensors) within a single device, allowing it to adapt to various operational requirements while maintaining reliable performance in each function.
