Manned Space Station With Solid Structure and Sealed Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manned space stations face structural complexity due to the need to withstand external threats and provide life-support systems, while ensuring crew safety and mobility in case of damage or danger.
Innovation Solution
A space station design featuring a housing with multiple sealed compartments partitioned by bulkheads and an inner chamber with access openings, allowing crew to move between compartments through an inner cavity, and equipped with a metal structure for protection and integrated life-support systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple modules are used to provide different functions, then functional requirements are met, but structural complexity increases
Solution Approach 1:
The patent combines multiple functional modules into a single integrated space station structure. The housing integrates life-support systems, workspace, crew rest spaces, and protection functions into one unified structure rather than separate modules, thereby reducing structural complexity while maintaining all required functions.
Solution Approach 2:
The space station housing is designed as a multi-functional structure that simultaneously provides life-support, workspace, crew accommodation, and protection against external threats. This universal design eliminates the need for separate specialized modules, reducing overall structural complexity.
2Reliability
If separate compartments are provided for crew safety, then safety requirements are met, but structural complexity increases
Solution Approach 1:
The space station housing is segmented into multiple independently sealable compartments that can be isolated from each other. This segmentation allows the crew to be separated into different safe zones in case of damage to one compartment, meeting safety requirements while maintaining a unified structural design.
Solution Approach 2:
The patent implements a nested compartment structure where multiple sealed compartments are arranged within the housing. The inner chamber is surrounded by multiple compartments, creating a nested arrangement that provides safety through compartmentalization without requiring separate external modules.
3Object-affected harmful factors
If a metal structure is used for protection, then protection against external threats is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent employs composite material construction for the housing structure, combining metal elements with other materials to achieve the required protection against radiation and meteorite impacts. This composite approach provides enhanced protection while simplifying manufacturing compared to purely metal structures.

AI summary
A space station includes a housing that defines an interior space. An inner chamber is located in the interior space and defines an inner cavity that is sealable from the remainder of the interior space. At least one bulkhead is arranged in the interior space to partition the interior space into at least two compartments that are hermetically sealable from one another. One compartment can be accessed from another compartment via the inner cavity of the inner chamber. The inner cavity is sealable against each compartment. Openings in an outer surface of the housing enable crew members to leave a damaged compartment through the opening. Thus, alternative routes exist to leave a damaged compartment, i.e., either through the inner cavity or through the opening in the outer surface of the housing. When one compartment is damaged, the adjacent compartments are still operative because they are sealed from the damaged compartment.
