Decentralized Modular Space Body Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing space modules are limited in their ability to be arbitrarily assembled and require a central control module, leading to complex and costly systems with increased computer capacity needs as the space body grows, and lack decentralized resource management, making them inflexible and prone to resource failures.
Innovation Solution
A space body composed of interchangeable modules with decentralized resource management, each equipped with its own processor-controlled controller, supply interfaces for gas, liquid, and electric resources, and a standardized multiple connection for various supply lines, allowing for modular expansion and redundancy through networked control and resource distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a central control module is used to coordinate space modules, then control tasks can be managed, but the system complexity and cost increase significantly
Solution Approach 1:
The control system is segmented into decentralized control units distributed across individual space modules rather than a single central control module. Each module has its own control unit that can autonomously manage local control tasks, eliminating the need for complex central coordination while maintaining overall system functionality.
Solution Approach 2:
Each space module is equipped with its own control unit that enables self-service operation. The control units autonomously manage their respective modules without requiring external coordination, reducing the complexity of central control while ensuring each module can function independently or in coordination with others through standardized interfaces.
2Adaptability or versatility
If the space body is expanded by coupling more space modules, then functionality increases, but the computer capacity requirement of the central controller increases
Solution Approach 1:
Control capacity is segmented and distributed across multiple independent control units in each space module rather than concentrated in a single central controller. This allows the system to scale functionality by adding modules without proportionally increasing the computer capacity of any single unit, as each module manages its own control tasks locally.
3Reliability
If redundant systems are used to compensate for controller failures, then reliability improves, but system complexity and cost increase
Solution Approach 1:
The control system is divided into multiple independent control units distributed across different space modules. This segmentation provides inherent redundancy - if one control unit fails, other modules with their own control units can continue to operate independently or take over functions, providing failure safety without requiring complex redundant systems within each controller.
Solution Approach 2:
Each control unit is designed to be self-sufficient and autonomous, capable of independent operation without relying on redundant backup systems. The decentralized architecture ensures that failure of one control unit does not compromise the entire system, as other control units continue to manage their respective modules independently.
4Ease of operation
If resources are managed centrally, then coordination is simplified, but the system lacks flexibility and is prone to single points of failure
Solution Approach 1:
Resource management is segmented and distributed across multiple control units in different space modules rather than centralized in one location. Each control unit manages resources locally within its module, providing flexibility and adaptability while maintaining coordination through standardized interfaces and communication protocols between modules.

AI summary
A space body has at least two space modules which can be interchangeably connected to one another. At least one closable connection opening is in each case provided on the space modules, via which a passage is produced when the space modules are connected. Furthermore, at least one coupling device connects in each case the space modules to one another. A supply interface is provided for coupling a supply line of the space modules.
