Docking System Adapter for Standardized CBM Mounting Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing space station modules require selection of a docking system interface during manufacturing, making it difficult and expensive to change later, and there is a need for a standardized bulkhead design to accommodate both active and passive CBMs.
Innovation Solution
An adapter that facilitates the attachment of a docking system to a common berthing mechanism (CBM) mounting interface, allowing for flexible conversion between different mounting mechanisms without replacing the integrated mechanism, using a hollow structure with interfacing rings and fastening holes for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a docking system interface is selected during manufacturing, then the module can be structurally attached to compatible systems, but changing the interface later becomes extremely difficult and expensive
Solution Approach 1:
The bulkhead is divided into two separate interfaces: a CBM interface that is integrally welded into the module structure during manufacturing, and a docking system interface that is attached via a removable adapter. This segmentation allows the permanent CBM interface to remain while the docking system interface can be changed by replacing the adapter, thus resolving the contradiction between structural reliability and interface adaptability.
Solution Approach 2:
An adapter serves as an intermediary component between the CBM bulkhead interface and the docking system interface. The adapter translates between these two different interfaces, allowing the module to connect to various docking systems without requiring changes to the integral CBM bulkhead structure. This intermediary enables interface versatility while maintaining the reliability of the original structural attachment.
2Reliability
If different bulkhead interfaces are designed for different docking systems, then each system can be optimized for its specific interface, but module production becomes less efficient and more costly
Solution Approach 1:
The CBM bulkhead interface is designed as a universal standard that can accommodate multiple docking system interfaces through the use of different adapters. Instead of designing unique integral bulkheads for each docking system (IBDM, NDS, etc.), the same CBM bulkhead can work with any docking system by simply changing the adapter. This multi-functionality approach optimizes production efficiency while maintaining interface-specific performance through dedicated adapters.
3Ease of manufacture
If a standardized CBM bulkhead design is used, then manufacturing is streamlined and costs are reduced, but the ability to accommodate different docking systems is limited
Solution Approach 1:
The adapter acts as an intermediary that bridges the standardized CBM bulkhead interface and various proprietary docking system interfaces. The standardized CBM bulkhead provides manufacturing simplicity and cost reduction, while the interchangeable adapters provide docking system compatibility. This two-component approach (standardized bulkhead + specific adapter) resolves the contradiction between production standardization and docking versatility.
Solution Approach 2:
The system transitions from a static, fixed interface design to a dynamic, reconfigurable interface system. The standardized CBM bulkhead remains fixed during manufacturing, but the docking system interface becomes dynamic through the ability to swap adapters. This dynamic approach allows the system to adapt to different docking systems while maintaining manufacturing standardization benefits.

AI summary
An adapter for attaching a docking system to a common berthing mechanism mounting interface is a device that enables a system with an integrated mounting mechanism to be coupled to an external system by using an alternate mounting mechanism. The device includes a hollow body, a first interfacing ring, a second interfacing ring, several first holes, and several second holes. The hollow body enables the transition from the integrated mounting mechanism to the alternate mounting mechanism. The first interfacing ring enables the fastening of the hollow body to the alternate mounting mechanism. The first holes enable the use of appropriate fasteners to secure the hollow body to the alternate mounting mechanism. The second interfacing ring enables the fastening of the hollow body to the integrated mounting mechanism. The second holes enable the use of appropriate fasteners to secure the hollow body to the integrated mounting mechanism.
