Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-space testing and operations face challenges with hazardous debris generation, limited volume for enclosed tests, and the need for extensive secondary development efforts due to externally observable classified equipment, which complicates debris mitigation and operation safety.
Innovation Solution
An expandable and contractable enclosure system for in-space robotics testbeds that can contain objects, expand to a larger volume for operations, and contract to a compact form for launch, equipped with a robotic arm and expandable supports, sensors, and launch restraints to manage debris and facilitate safe in-space testing and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If in-space testing and operations are conducted with traditional enclosed volumes, then debris containment is achieved, but the available workspace is limited by launch volume
Solution Approach 1:
The enclosure system transitions from a static fixed-volume structure to a dynamic variable-volume structure that can expand and contract. The enclosure volume is adjusted based on operational requirements: expanded during workspace operations to provide ample volume, and contracted during launch to minimize volume constraints. This dynamic adaptation resolves the contradiction between needing large workspace volume and managing enclosure system complexity.
Solution Approach 2:
The enclosure system is divided into multiple expandable and contractable sections that can be independently controlled. This segmentation allows the enclosure to be compact during launch and then expanded to provide sufficient workspace volume. The modular segmented structure manages complexity by breaking down the large volume requirement into manageable expandable units.
2Reliability
If in-space testing is conducted with fixed enclosed volumes, then launch constraints are met, but debris mitigation capability is reduced
Solution Approach 1:
The enclosure system dynamically adjusts its volume to optimize both debris mitigation reliability and enclosure volume. When debris mitigation is the priority (such as during containment operations), the enclosure expands to provide adequate workspace for safe operations. During launch, the enclosure contracts to meet volume constraints while maintaining structural integrity for debris containment. This dynamic volume adjustment ensures reliable debris mitigation across different operational phases.
3Reliability
If extensive secondary development efforts are implemented for test setups, then operational safety is improved, but system complexity and development time increase
Solution Approach 1:
The enclosure system is designed as a universal multi-functional platform that integrates debris containment, workspace provision, and operational safety features into a single system. Rather than implementing separate secondary development efforts for each safety requirement, the enclosure provides integrated functionality that addresses multiple safety concerns simultaneously, reducing overall system complexity and development time while maintaining high operational safety standards.
