Engineering Contradiction Analysis
1Adaptability or versatility
If current best-practice manufacturing methods are used for extra-terrestrial spacecraft fabrication, then functional devices can be manufactured with a range of materials, but the complexity of integrating thousands of unique parts made using diverse processes and raw materials increases significantly
Solution Approach 1:
The patent segments the spacecraft into standardized modular units that can be independently manufactured and then assembled. This breaks down the complex integration of thousands of unique parts into manageable modules, each with standardized interfaces, thereby reducing overall system complexity while maintaining material diversity across different module types.
Solution Approach 2:
The patent employs universal standardized interfaces and common structural elements that can accommodate multiple material types and functional requirements. This allows the same assembly framework to work with diverse materials, reducing the need for unique integration processes for each part while maintaining adaptability.
2Extent of automation
If self-replicating systems with macro-scale building blocks are created, then high-level system design challenges are addressed, but the parts require a high-degree of embedded complexity including conventional actuators and processors
Solution Approach 1:
The patent implements self-service through standardized interfaces that enable modules to autonomously connect and configure themselves when brought together. The modular architecture with standardized mechanical, electrical, and data interfaces allows systems to self-assemble and self-configure, enabling self-replication without requiring highly complex embedded systems in each part.
3Adaptability or versatility
If reconfigurable spacecraft are designed to adapt to environment, then efficiency and flexibility of space exploration missions are improved, but the system requires complex mechanisms for transforming and reorienting
Solution Approach 1:
The patent employs dynamic reconfigurability where standardized modular units can be easily added, removed, or repositioned through simple standardized interfaces rather than complex transforming mechanisms. This allows the spacecraft to adapt its configuration by reassembling modular components, achieving flexibility without requiring complex in-situ transformation mechanisms.

AI summary
A system of flexural, actuating, and semiconducting elements of part-types necessary to assemble actuated robotic systems. These parts are joined with a common interface, interlocking with neighboring parts to form a regular lattice structure. Primary considerations for the design of the part interfaces include ease of assembly and the ability to transfer mechanical loads and electronic signals to neighboring parts. The parts are designed to be assembled vertically so structures can he built incrementally one part at a time. They can be easily fabricated at a range of length-scales using a variety of two-dimensional manufacturing processes. These processes include, for example, stamping and laminating, which enable high-throughput production. The simple mechanical interfaces between parts also enable disassembly allowing for reconfigurability and reuse. The interlocking nature of these assemblies allows loads to be distributed through many parallel load-paths.
