Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cryogenic containers require complex and costly individual sockets for each line, making it difficult to connect the inner container to multiple lines in a structurally simple manner, especially for large-scale applications.
Innovation Solution
A double-walled cryogenic container design with a fluid distribution container that extends from the inner container into the evacuable space, featuring multiple openings for line connections, allowing for a central arrangement of lines and reducing material usage and production complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual sockets are provided for each line connection to the inner container, then each line can be connected independently, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The patent merges multiple individual socket functions into a single integrated fluid distribution container that extends from the inner container wall into the evacuable space. This container provides multiple opening(s) for line connections, eliminating the need for separate individual sockets for each line while maintaining independent connection capability.
Solution Approach 2:
The fluid distribution container serves multiple functions simultaneously: it acts as a structural component extending from the inner container, provides a distribution interface for multiple lines, and facilitates fluid communication between the inner container and external lines. This multi-functionality reduces the overall number of components needed.
2Ease of operation
If multiple individual connections are made to the inner container wall, then each line can be connected directly, but the number of holes and weld edges increases manufacturing complexity
Solution Approach 1:
The patent combines multiple connection points into a single fluid distribution container structure. Instead of drilling multiple separate holes in the inner container wall for different lines, only one opening is made to accommodate the fluid distribution container, which then provides multiple line connection points. This significantly reduces the number of holes and weld edges required.
Solution Approach 2:
The connection function is segmented between the inner container (providing the main structure and single opening) and the fluid distribution container (providing multiple line connection points). This segmentation allows the inner container to remain simple while the fluid distribution container handles the complexity of multiple connections.
3Manufacturing precision
If predefined calculations and defined spacing are used for nozzle dimensioning, then precise positioning is achieved, but manufacturing cost and complexity increase
Solution Approach 1:
The fluid distribution container provides a universal connection interface that can accommodate multiple lines with different requirements. The container's opening(s) are designed to receive the fluid distribution container, which then provides standardized connection points for lines, eliminating the need for individually calculated and positioned nozzles for each line.
