Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportable filling stations for pressurized fluids like hydrogen and liquefied natural gas face challenges in meeting strict safety requirements for fire and explosion protection, particularly when quickly setting up on-site for emergency or temporary applications, as they often lack effective ventilation and protection for fluid circuit components.
Innovation Solution
A transportable filling station design featuring a floor-mounted container with support structures forming a passage for ambient air flow, where fluid circuit components are exposed to ventilation to dilute and dissipate escaped vapors, and electrical components are isolated to minimize spark risks, with modular configurations for easy assembly and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fluid circuit components are enclosed in a sealed container for protection, then component safety is improved, but vapor dilution and dissipation capability deteriorates
Solution Approach 1:
The container is divided into different zones with different ventilation characteristics. The fluid circuit components are placed in a locally protected area while maintaining overall container ventilation through strategic opening placement, achieving both component protection and vapor dissipation
Solution Approach 2:
The support structures serve as intermediary elements that both protect the fluid circuit components and facilitate ventilation. These structures create protected mounting surfaces while simultaneously forming ventilation channels and directing air flow through the container
2Loss of time
If the filling station is designed for rapid deployment, then setup time is reduced, but safety compliance deteriorates
Solution Approach 1:
The filling station is segmented into modular components (container, support structures, fluid circuit components, electrical components) that can be independently manufactured and assembled. This modular design enables rapid deployment while ensuring each component meets safety requirements through standardized design
Solution Approach 2:
Safety-critical features such as ventilation channels, support structures with integrated protection, and component mounting positions are pre-designed and pre-positioned in the container structure. This preliminary configuration ensures safety compliance is built-in from the start, eliminating the need for complex safety installations during rapid deployment
3Device complexity
If electrical components are placed close to fluid circuit components for compact design, then device complexity is reduced, but ignition risk increases
Solution Approach 1:
Electrical components are extracted from the immediate vicinity of fluid circuit components and placed in separate zones within the container. This spatial separation reduces ignition risk while the overall compact container design maintains portability and ease of deployment

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures rapid on-site setup of a gas station that meets safety standards by diluting escaped vapors to non-hazardous levels and protecting components from ignition risks, while allowing for easy maintenance and transportability through modular design.
Implementation Method 1
a passage between one another through which ambient air can freely flow via openings in the lateral sides
Implementation Method 2
Any pressurized fluid vapors escaping from the fluid circuit components due to a failure or leak during operation are diluted by the ambient air flow in the passageway to a harmless, non-ignitable mixture and dissipated
