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 reliability and safety are limited
Solution Approach 1:
The patent implements bidirectional communication between the vehicle terminal and dispenser terminal, allowing real-time feedback exchange. The vehicle terminal can send fueling requests and receive confirmation, while the dispenser terminal can send status updates and control responses. This two-way feedback mechanism significantly improves communication reliability compared to unidirectional infrared communication.
Solution Approach 2:
The patent replaces traditional mechanical/unidirectional communication systems with an electronic bidirectional communication system using wireless networks. This substitution enables more reliable data transmission, real-time monitoring, and active safety management, resolving the limitations of conventional unidirectional communication.
2Productivity
If conventional hydrogen fueling protocols are used, then fueling process is established, but efficiency and responsiveness are slow
Solution Approach 1:
The patent implements preliminary actions by establishing bidirectional communication and negotiating protocols before the actual fueling process begins. The vehicle and dispenser terminals exchange information, confirm compatibility, and prepare control parameters in advance, enabling faster and more efficient fueling execution without delays during the process.
Solution Approach 2:
The patent introduces dynamic protocol negotiation and real-time parameter adjustment capabilities. The communication system can adaptively select optimal protocols and adjust fueling parameters based on real-time conditions, significantly improving fueling efficiency and reducing time loss compared to static conventional protocols.
3Reliability
If bidirectional communication is implemented for real-time control, then safety and responsiveness improve, but system complexity increases
Solution Approach 1:
The patent implements a universal bidirectional communication framework that handles multiple functions including safety monitoring, protocol negotiation, parameter exchange, and control commands through a single integrated system. This multi-functional approach improves safety and responsiveness while minimizing the increase in system complexity by consolidating functions rather than adding separate systems.
