Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single evaluation device is used to test magneto-resistive effect elements under multiple temperature conditions, then the device structure remains simple, but the throughput is remarkably lowered due to repeated temperature setting
Solution Approach 1:
The evaluation device is divided into multiple independent evaluation units (first evaluation unit, second evaluation unit, etc.), each capable of independently testing sensors under different conditions. This segmentation allows parallel processing of multiple sensors simultaneously, thereby increasing throughput without requiring a single complex reconfigurable system.
Solution Approach 2:
Each evaluation unit is designed with universal functionality to handle multiple test conditions through standardized interfaces and configurations. The units can evaluate different sensor types (magneto-resistive effect elements, pressure sensors, etc.) under various conditions without requiring complete reconfiguration, maintaining operational simplicity while enabling diverse testing capabilities.
2Productivity
If temperature conditions are changed for the same sensor evaluation, then comprehensive testing is achieved, but time is lost due to repeated temperature setting
Solution Approach 1:
Different temperature conditions are pre-configured in separate evaluation units before the evaluation process begins. Each unit is permanently set to a specific temperature condition, eliminating the need for dynamic temperature reconfiguration during testing. Sensors are simply routed to the appropriate pre-configured unit, significantly reducing setup time.
Solution Approach 2:
Multiple evaluation units operate simultaneously and continuously, each processing sensors under its designated conditions. This parallel continuous operation eliminates idle time associated with sequential temperature changes, maintaining constant productive action across all evaluation channels.
3Reliability
If multiple evaluation conditions are applied to the same sensor sequentially, then thorough testing is performed, but the testing process becomes time-consuming
Solution Approach 1:
The testing process is segmented across multiple parallel evaluation units, each dedicated to specific test conditions. Sensors are distributed to appropriate units based on required test conditions, enabling simultaneous execution of multiple test scenarios. This maintains comprehensive testing coverage while dramatically improving efficiency through parallel processing.
Solution Approach 2:
The testing approach transitions from sequential single-dimension testing to parallel multi-dimensional testing. By adding the spatial dimension of multiple simultaneous evaluation units, the system achieves comprehensive testing across different conditions without the time penalty of sequential execution, effectively moving from one-dimensional sequential processing to multi-dimensional parallel processing.
