Modular Rail Fluid Dispensing for Mobile Refueling Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing a network of fixed fluid refueling stations across a large territory is difficult and costly, especially for rail vehicles with varying refueling needs, as seen in US 2019/041004 A1, which does not address the mobility and adaptability of fluid distribution systems.
Innovation Solution
A modular fluid distribution system with interchangeable containers, including a first container for a fluid reservoir and a second container with a conditioning and distribution unit, allowing easy deployment and refueling along rails based on demand, and optionally a third container for increased capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a network of fixed refueling stations is established across the territory, then refueling availability is improved, but establishment cost and complexity increase
Solution Approach 1:
The patent transforms the static fixed refueling station into a dynamic mobile refueling unit that can be relocated along railway tracks. This mobility allows a single unit to serve multiple locations sequentially, providing refueling availability across the territory without requiring a permanent network of fixed stations, thereby reducing overall system complexity and establishment cost
Solution Approach 2:
The refueling system is divided into modular components including the mobile refueling unit with separable fuel tanks and conditioning equipment. This segmentation enables flexible deployment where individual modules can be transported and reconfigured as needed, allowing comprehensive territorial coverage through coordinated movement of modular units rather than establishing fixed infrastructure everywhere
2Ease of operation
If fixed refueling stations are distributed across the territory, then refueling access is improved, but cost increases
Solution Approach 1:
The mobile refueling unit travels along railway tracks to provide refueling services at different locations, transforming the static access model into a dynamic one. This allows the system to maintain good refueling access across the territory while concentrating infrastructure resources in a single movable unit, significantly reducing the cost compared to establishing fixed stations at every location
3Reliability
If the system is designed with fixed infrastructure, then refueling reliability is improved, but mobility is lost
Solution Approach 1:
The patent implements a mobile refueling unit equipped with stable rail-mounted propulsion and positioning systems that can reliably travel to designated locations. The unit maintains refueling reliability through consistent operational procedures and stable connections during fueling, while simultaneously achieving mobility by design, thus resolving the contradiction between reliability and adaptability
4Ease of repair
If modular containers are used, then ease of replacement is improved, but system complexity increases
Solution Approach 1:
The refueling system employs modular containers with standardized interfaces for fuel tanks, conditioning units, and support equipment. These segmented modules can be independently replaced or maintained by detaching and reattaching standardized components, significantly improving ease of replacement. The complexity increase is minimal and offset by the operational benefits of rapid module interchangeability
