Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unidirectional infrared communication devices are used for hydrogen fueling control, then wireless communication is achieved, but communication efficiency and reliability are limited
Solution Approach 1:
The patent implements bidirectional communication between the mobility device and dispenser, allowing real-time feedback exchange. The mobility device can send fueling status, temperature, and pressure information to the dispenser, while receiving control commands, thereby improving both communication reliability and fueling efficiency through active monitoring and control.
Solution Approach 2:
The patent inverts the conventional unidirectional communication model by implementing bidirectional communication where both the mobility device and dispenser can actively transmit and receive information. This reversal enables the mobility device to initiate communications and share real-time data, transforming the passive communication system into an active, efficient fueling process.
2Adaptability or versatility
If conventional hydrogen fueling protocols are used, then fueling process is established, but compatibility and interoperability are insufficient
Solution Approach 1:
The patent implements a universal discovery and pairing mechanism that works across different communication technologies (infrared, Bluetooth, Wi-Fi). The mobility device can discover dispensers and establish connections using multiple communication protocols, making the system adaptable to various environments and improving both compatibility and reliability.
Solution Approach 2:
The patent introduces dynamic protocol selection and negotiation mechanisms. The system can adaptively choose the most appropriate communication protocol based on available technologies and environmental conditions, enabling flexible and reliable fueling operations across different scenarios and enhancing overall system compatibility.
3Loss of time
If discovery and pairing procedures are simplified, then fueling process starts faster, but safety checks may be compromised
Solution Approach 1:
The patent performs discovery, pairing, and safety checks as preliminary actions before the actual fueling process begins. By completing authentication, compatibility verification, and safety parameter checks in advance, the system minimizes fueling preparation time while ensuring all safety requirements are met before hydrogen transfer starts.
Solution Approach 2:
The patent implements continuous monitoring during the fueling process, maintaining real-time communication between the mobility device and dispenser. Temperature, pressure, and flow rate parameters are continuously tracked, ensuring safety is maintained throughout the fueling operation without requiring interruptive safety checks, thus reducing overall time loss.

AI summary
The method according to an embodiment of the present invention includes the steps of: sharing information about pairing between a mobility and a dispenser for fueling hydrogen to the mobility, and discovering the dispenser; checking information about interoperability or compatibility between the dispenser and the mobility on the basis of the information about pairing; performing pairing between the dispenser and the mobility, on the basis of the information about pairing; and, on the basis of the information about interoperability or compatibility between the dispenser and the mobility, conducting a subsequent process related to a fueling protocol or a communication protocol for a process in which the dispenser fuels hydrogen to the mobility through transmittance and reception of at least one message to and from the dispenser.
