Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single large-capacity portable tank is used for hydrogen storage, then the storage capacity is increased, but the manufacturing complexity and regulatory compliance difficulty increase
Solution Approach 1:
The system divides the hydrogen storage function into multiple separate portable tanks (first portable tank and second portable tank) instead of using a single large tank. Each tank can be independently manufactured to smaller, more manageable capacities that easier meet regulatory requirements while collectively providing the needed total storage capacity.
2Productivity
If multiple supply units with removable portable tanks are provided, then the efficiency of hydrogen storage and the ability to simultaneously fill multiple tanks is improved, but the device complexity increases
Solution Approach 1:
The supply units are designed with universal interfaces that can accept different portable tanks (first or second tank) interchangeably. The hydrogen generating unit can supply hydrogen to multiple tanks through these standardized supply units, enabling flexible and efficient filling operations without requiring complex specialized equipment for each tank type.
3Loss of energy
If hydrogen is generated and stored during load testing, then the utilization of generated hydrogen is improved, but the safety risks of handling and storing hydrogen increase
Solution Approach 1:
The system introduces supply units as intermediary components between the hydrogen generating unit and the portable tanks. These supply units act as controlled interfaces that manage the hydrogen transfer process, incorporating safety mechanisms and control functions to mitigate the inherent safety risks of hydrogen handling while enabling efficient utilization of the generated hydrogen.

Function Achieved in This Case
Enables efficient storage and utilization of hydrogen during load testing by allowing multiple portable tanks to be filled simultaneously, facilitating efficient hydrogen storage and use without external power sources, while maintaining operational safety.
Implementation Method 1
a hydrogen generating unit that performs electrolysis based on power supplied from the power source being tested to generate hydrogen
Implementation Method 2
a compressor that operates based on power from the power source being tested and compresses the hydrogen obtained in the hydrogen generating unit. The hydrogen made to a high pressure state by the compressor is supplied to the two or more supply units
Data Source
AI summary
A load testing device includes a connection unit to which a power source being tested is connected, a hydrogen generating unit that performs electrolysis based on power supplied from the power source being tested to generate hydrogen, two or more supply units to which hydrogen obtained in the hydrogen generating unit passes and to which a portable tank is removably attached, and an operational unit that has a load amount adjustment switch and a display unit. The load amount of the hydrogen generating unit is switched depending on an operational state of the load amount adjustment switch. The display unit displays at least one of an attachment status of the portable tank and a filling status of hydrogen in the two or more supply units.
