Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simulation and validation processes are implemented for hydrogen dispenser fill control formulas, then reliability and accuracy of hydrogen dispensing are improved, but device complexity and validation time are increased
Solution Approach 1:
The patent implements simulation of fill operations before actual dispensing to validate the fill control formula. By performing preliminary validation through simulation, the system ensures reliability of the dispensing process without requiring complex real-time validation infrastructure during actual operation.
Solution Approach 2:
The patent creates a virtual copy of the fill operation through simulation, using template data and static parameters to replicate actual dispensing scenarios. This copying approach allows validation without requiring duplicate physical equipment, thus improving reliability while limiting the increase in device complexity.
2Measurement precision
If simulation of fill operations is performed to validate fill control formula, then accuracy of hydrogen dispensing is improved, but validation time and processing duration are increased
Solution Approach 1:
The simulation validates the fill control formula in advance before actual dispensing operations. By performing validation preliminarily, the system ensures measurement precision is achieved without requiring repeated validation during each dispensing operation, thus limiting time loss.
Solution Approach 2:
The simulation uses template data and static parameters to perform partial validation of the fill control formula, focusing on critical aspects such as process limits and protocol compliance. This partial action approach achieves sufficient accuracy without requiring exhaustive validation of every possible scenario, thereby reducing validation time.
3Reliability
If comprehensive validation including template data and static parameters is implemented, then reliability of hydrogen fueling is improved, but ease of operation is reduced
Solution Approach 1:
The validation system uses template data and static parameters that are automatically processed through the simulation. The system performs self-validation by comparing simulated results against expected outcomes, reducing the need for manual intervention and maintaining ease of operation while improving reliability.
Solution Approach 2:
The validation apparatus is designed to handle multiple validation scenarios using a unified simulation framework. By making the validation system universal and multi-functional, it can process different template data and static parameters through the same interface, thereby maintaining ease of operation while comprehensively improving reliability.

AI summary
Validating of a fill control formula used by a hydrogen dispenser for dispensing hydrogen is described. Template data of the hydrogen dispenser related to dispensing of hydrogen by the hydrogen dispenser over a period of time is received, as well as static parameter values. One or more fill operations for dispensing hydrogen to one or more hydrogen fuel tanks may be simulated based on the template data and static parameters, as well as based on the fill control formula utilized in the hydrogen dispenser. A comparison of one or more fill operation parameter values calculated by simulating the one or more fill operations and one or more values of one or more similar fill operation parameters in the template data may be output on a user interface.
