Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional testing system is used, then speed sensor testing can be performed, but the system weighs over sixty pounds and is limited in portability
Solution Approach 1:
The conventional testing system is divided into separate functional components (power source, motor, sensor port, converter member) that can be independently configured and optimized, allowing the overall system weight to be reduced while maintaining testing functionality
Solution Approach 2:
The testing device is designed with a universal sensor port that can accommodate different types of speed sensors through the converter member, enabling a single lightweight device to perform multiple testing functions across various sensor types
2Reliability
If a conventional testing system is used, then speed sensor testing is possible, but the system is limited to specific traction motors with alternating current speed sensors
Solution Approach 1:
The sensor port incorporates a converter member that can be adjusted to accommodate different sensor types and configurations, making the testing device compatible with both alternating current and direct current speed sensors across various traction motor types
Solution Approach 2:
The converter member is designed to be movable and adjustable, allowing the sensor port depth and configuration to be dynamically changed to match different sensor requirements, thereby increasing adaptability to various traction motor systems
3Adaptability or versatility
If the sensor port depth is fixed, then the structure is simpler, but the device cannot accommodate different sensor types requiring different depths
Solution Approach 1:
The converter member is designed as a movable component that can be positioned at different depths within the sensor port, allowing the same physical structure to accommodate various sensor types without requiring multiple fixed-depth ports or complex interchangeable components
