Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems face challenges in efficiently handling multiple fluid and solid media in confined spaces while meeting design criteria for space and weight constraints, necessitating a more integrated and compact pipe arrangement.
Innovation Solution
A multi-walled pipe section with nested layers is employed to transport and accommodate different media, integrating functions such as fluid transport, thermal insulation, and heat exchange, allowing for a compact and efficient pipe system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate pipes are used for each fluid medium and solid medium, then each medium can be transported independently, but the space required increases and the system becomes more complex in confined spaces
Solution Approach 1:
The patent applies nesting by placing multiple pipe layers concentrically within each other, where each pipe layer transports a different fluid medium or accommodates solid medium. This nested configuration allows independent transport of multiple media while occupying minimal space, directly resolving the contradiction between reliable independent transport and space efficiency in confined vehicle environments.
Solution Approach 2:
The patent merges multiple separate pipe functions into a single multi-walled pipe structure where different pipe layers handle different media. This combining approach maintains the independence of each medium's transport path while consolidating the physical footprint, thereby reducing the overall area occupied by the pipe arrangement in confined spaces.
2Reliability
If multiple separate pipes are used for different media, then each medium can be handled separately, but the overall weight and number of parts increase
Solution Approach 1:
The patent combines multiple separate pipe components into a single integrated multi-walled pipe structure. By merging the functions of multiple pipes into one consolidated component, the total weight of the pipe arrangement is reduced while maintaining separate handling capabilities for different media through the nested pipe layers.
Solution Approach 2:
The multi-walled pipe structure serves multiple functions simultaneously - each pipe layer can transport different fluid media or accommodate solid media, thermal insulation can be integrated in the walls, and heat exchange can occur between layers. This multi-functionality reduces the need for additional separate components, thereby reducing overall weight.
3Area of stationary object
If functional integration is implemented in multi-walled pipes, then space is reduced and weight is decreased, but the manufacturing complexity increases
Solution Approach 1:
The patent segments the multi-walled pipe into distinct pipe layers, where each layer can be manufactured separately and then assembled into the final multi-walled structure. This segmentation approach reduces manufacturing complexity by allowing each layer to be produced using standard pipe manufacturing processes, followed by controlled assembly, rather than requiring complex integrated manufacturing.
Solution Approach 2:
The nested structure allows for modular assembly where inner pipe layers are placed within outer pipe layers in a systematic sequence. This nesting approach simplifies manufacturing by enabling step-by-step assembly of standardized components, reducing the overall manufacturing complexity despite the integrated functional design.
Applied Scientific Principles
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 multi-walled pipe arrangement enhances safety, reduces overall footprint, and improves media transport efficiency by combining multiple functions into a single pipe section, suitable for vehicles with limited space.
Implementation Method 1
a first pipe layer provides a first function and a second pipe layer provides a second function that is different from the first function... each pipe layer is chosen to transport a fluid medium or to accommodate a solid medium
Implementation Method 2
the pipe arrangement combines the transport of different media and other functions in a single multi-walled pipe section... thermal insulating function
Implementation Method 3
a heat exchanging function for exchanging heat between adjacent pipe layers

AI summary
In order to allow functional integration in a single structure for fluid transport in vehicles, a pipe arrangement is provided that includes at least one multi-walled pipe section that includes a multi-walled pipe for separately transporting each fluid medium or for separately accommodating each solid medium. In one solution, the multi-walled pipe section includes at least two nested pipe layers and the multi-walled pipe section is formed in a location of the pipe arrangement that is disposed in a confined space of the vehicle. In another solution, the multi-walled pipe section includes at least three nested pipe layers, wherein each pipe layer is chosen to transport a fluid medium or to accommodate a solid medium.
