Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual visual observation and recording methods are used, then device complexity is reduced, but measurement precision and reliability deteriorate due to human error and irregular monitoring frequency
Solution Approach 1:
The patent replaces manual visual observation with an automated load cell-based measurement system. The load cell converts mechanical force (weight of fluid) into electrical signals, which are then processed by a control circuit to provide automated, continuous monitoring. This substitution eliminates human error while maintaining relatively simple device architecture through the use of standard sensing components.
2Productivity
If manual monitoring methods are used, then device complexity is low, but productivity decreases due to substantial time required for measurement and recording
Solution Approach 1:
The measurement system performs self-service by automatically measuring fluid levels without requiring human intervention. The load cell continuously monitors weight changes, and the control circuit automatically records and processes the data, enabling high-frequency monitoring that would be impractical manually. This automation significantly increases productivity while keeping the device structure manageable.
Solution Approach 2:
The system enables continuous monitoring of fluid levels through the persistent operation of the load cell and control circuit. Unlike manual methods that occur at discrete intervals, the automated system maintains constant surveillance of fluid weight, ensuring no changes are missed and enabling real-time response to fluid level variations.
3Measurement precision
If automated load cell measurement is implemented, then measurement precision and productivity improve, but device complexity increases due to additional components and setup requirements
Solution Approach 1:
The measurement system is divided into distinct functional modules: the load cell sensing element, the load measurement assembly housing, the control circuit, and the fluid container. This segmentation allows each component to be optimized independently and facilitates easier maintenance and calibration. The modular structure manages complexity by organizing functions into separate, manageable units rather than a monolithic system.
