Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydrogen storage tank is used to supply high-pressure hydrogen, then hydrogen supply capability is improved, but device size and complexity increase, reducing mobility
Solution Approach 1:
The patent removes the hydrogen storage tank from the system entirely. Instead of storing hydrogen and then pressurizing it, the system directly pressurizes hydrogen from a source through a pressurizing unit, eliminating the need for large storage tanks and reducing overall device complexity while maintaining hydrogen supply capability
Solution Approach 2:
The system transitions from a static storage-based approach to a dynamic pressurization-based approach. The pressurizing unit dynamically compresses hydrogen as needed, allowing the system to adapt to varying demand without requiring oversized storage capacity, thereby improving mobility
2Reliability
If manual operation protocols are implemented for safety, then safety control is improved, but operational complexity and time consumption increase
Solution Approach 1:
The system implements automatic control functions that perform safety checks and refueling operations without requiring manual intervention. The control unit automatically monitors pressure, temperature, and flow parameters, and executes safety protocols, allowing the system to serve itself and eliminating the need for specialized manual operation knowledge
Solution Approach 2:
The system incorporates real-time monitoring of pressure, temperature, and flow parameters with automatic feedback control. Sensors continuously measure system state and feed this information back to the control unit, which automatically adjusts operations to maintain safety parameters, replacing manual safety protocols with automated feedback-based control
3Productivity
If real-time measurement and automatic control are implemented, then gas filling efficiency is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical control systems with electronic sensing and control. Microprocessors and sensors electronically monitor and control pressure, temperature, and flow parameters, achieving efficient automatic control with simpler, more integrated components compared to traditional mechanical control systems
Solution Approach 2:
The control unit is designed as a multi-functional integrated system that simultaneously performs measurement, calculation, control, and safety monitoring functions. This universal controller handles multiple tasks through a single device, reducing overall system complexity while maintaining high gas filling efficiency through coordinated control of multiple parameters

AI summary
Proposed is an apparatus for supplying hydrogen to various mobility products using hydrogen as fuel, that is, a hydrogen station. An integrated and mobile automatic hydrogen station achieves miniaturization by increasing space efficiency by adopting a structure that can supply high-pressure hydrogen directly from a hydrogen generating source without having a hydrogen storage tank so as to facilitate movement to sites operating hydrogen-fueled mobility products and ensure the airtightness of a gas supply path at the same time, and measures physical state variables such as pressure and temperature of gas being supplied in real time and automatically controls a supply process on the basis of the measurement so as to increase gas filling efficiency while improving safety and user convenience of a filling process.
