Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement devices are distributed across a facility, then measurement coverage is improved, but tracking and managing asset data becomes more difficult
Solution Approach 1:
An asset management system serves as an intermediary between distributed measurement devices and facility operators. The system automatically collects, stores, and manages asset data from multiple devices across the facility, eliminating the need for manual tracking while maintaining comprehensive measurement coverage.
Solution Approach 2:
The asset management system implements continuous feedback loops by automatically monitoring device locations, operational status, and maintenance requirements. This feedback mechanism enables real-time tracking of distributed assets without interfering with their measurement functions.
2Object-affected harmful factors
If asset tags are placed inside the high frequency shield, then shielding effectiveness is improved, but communication with external interrogators is blocked
Solution Approach 1:
The asset tag is extracted from the interior of the high frequency shield and positioned on the exterior surface. This separation allows the tag to communicate freely with external interrogators while the shield continues to protect the sensitive measurement circuitry from high frequency interference.
Solution Approach 2:
The measurement device is segmented into functionally independent components: the shielded measurement circuitry inside the high frequency shield and the unshielded asset tag on the outside. This segmentation allows each component to perform its specific function without interfering with the other.
3Device complexity
If manual tracking methods are used for measurement devices, then system complexity is reduced, but accuracy and reliability of asset management deteriorates
Solution Approach 1:
The asset management system operates autonomously by automatically collecting data from asset tags, tracking device locations, monitoring operational status, and generating maintenance alerts. This self-service capability eliminates manual intervention while ensuring high accuracy and reliability in asset management.
Solution Approach 2:
Manual mechanical tracking methods are replaced with an automated electronic asset management system that uses wireless communication between asset tags and interrogators. This substitution eliminates human error while maintaining system simplicity through standardized protocols and interfaces.
