Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unidirectional communication protocol is used for hydrogen fueling, then device complexity is reduced, but reliability and safety deteriorate due to lack of bidirectional verification and active management
Solution Approach 1:
The patent implements bidirectional communication where the mobility and dispenser exchange messages to negotiate communication protocols and fueling parameters. The communication controller actively manages the fueling process by receiving status information from the dispenser and sending control commands, creating a feedback loop that enhances safety and reliability compared to unidirectional communication.
2Productivity
If conventional unidirectional communication is used, then ease of operation is maintained, but productivity deteriorates due to slow and inefficient fueling process
Solution Approach 1:
The patent employs dynamic protocol negotiation where the communication controller and dispenser select optimal communication protocols based on their capabilities and the specific fueling scenario. This dynamic adaptation enables more efficient data exchange and faster fueling operations compared to rigid unidirectional protocols, while maintaining ease of operation through automated negotiation.
3Adaptability or versatility
If unidirectional communication protocol is implemented, then adaptability is limited, but device complexity is reduced
Solution Approach 1:
The patent implements a universal communication framework where the mobility and dispenser negotiate to find a common communication protocol from their respective supported protocols. This multi-functional approach allows the system to adapt to different protocol requirements and scenarios, enhancing compatibility and versatility while managing complexity through structured negotiation procedures.

AI summary
A method according to an embodiment of the present invention comprises the steps of: transmitting, to a communication entity related to a dispenser, a first message including a list of at least one first fueling protocol supported by a mobility and first communication protocols required for executing the one or more fueling protocols; and receiving, from the communication entity related to the dispenser, a response message including a second fueling protocol determined from the at least one first fueling protocol.
