Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the vehicle transmits refueling readiness information before the dispenser is coupled to the connector, then the refueling process can be initiated earlier, but the transmission timing becomes less precise and may occur before the vehicle is actually ready
Solution Approach 1:
The detection sensor is positioned to detect the dispenser before full coupling occurs, allowing the vehicle to prepare for refueling in advance. The signal transmitter is configured to transmit the refueling readiness signal at the precise moment when detection sensor confirms dispenser coupling, enabling preliminary preparation without sacrificing timing precision.
2Measurement precision
If the vehicle waits for complete dispenser coupling before transmitting the refueling readiness signal, then transmission timing precision is improved, but the refueling process initiation is delayed
Solution Approach 1:
The detection sensor begins detecting the dispenser as it approaches the connector, allowing the vehicle system to prepare refueling procedures in advance. Once the detection sensor confirms coupling, the signal transmitter immediately transmits the readiness signal, achieving both early preparation and precise timing.
Solution Approach 2:
The detection sensor acts as an intermediary between the physical coupling process and the signal transmission. It provides an intermediate detection state that triggers the signal transmitter to send the refueling readiness signal at the optimal moment, balancing early initiation with precise timing.
3Measurement precision
If a detection sensor is added to detect dispenser coupling, then the transmission timing precision is improved, but the device complexity increases
Solution Approach 1:
The detection sensor is integrated into the existing connector assembly, serving multiple functions: detecting dispenser coupling, verifying proper connection, and triggering the refueling readiness signal. This multi-functional design adds detection capability without proportionally increasing overall system complexity.
Solution Approach 2:
The detection sensor, signal transmitter, and connector are merged into a single integrated assembly. The detection sensor is positioned on the support plate near the connector, and both components share the same housing structure, reducing the number of separate parts and simplifying installation while maintaining detection precision.
