Innovation Solution
A method involving the design and manufacture of interlockable building bricks with a TiO2 shell portion, utilizing in-situ materials like Martian regolith, and 3D printing, which allows for modular structures to be created with a common outer surface and voids for reduced weight and increased structural efficiency, responding to topographic characteristics and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If modular building bricks are designed with interlocking mechanisms for easy assembly, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The building system is divided into modular bricks that can be independently manufactured and assembled. Each brick is a discrete unit with standardized interlocking features, allowing the complex structure to be built from simple, repeatable components that are easy to handle and assemble.
Solution Approach 2:
Multiple functional features are integrated into a single brick design: the interlocking protrusions and recesses combine structural connection, alignment, and stability functions. The shell portion integrates radiation shielding and structural integrity, merging protection and structural functions into one element.
2Reliability
If a shell portion containing TiO2 is added to protect against radiation, then reliability is improved, but weight of stationary object increases
Solution Approach 1:
The brick combines regolith material with TiO2 to create a composite structure. The TiO2 shell portion provides radiation shielding functionality while the regolith core provides structural mass, creating a composite material that achieves protection requirements with optimized weight compared to solid shielding materials.
Solution Approach 2:
The TiO2 shell is applied specifically to the outer surface of each brick where radiation exposure occurs, rather than distributing shielding material throughout the entire structure. This localized approach provides radiation protection where needed while minimizing additional weight.
3Weight of stationary object
If voids are created in the brick structure to reduce weight, then weight of stationary object is reduced, but strength decreases
Solution Approach 1:
The brick incorporates voids or porous structures within its composition, creating a material that balances weight reduction with structural integrity. The voids are strategically positioned and sized to minimize weight while maintaining sufficient strength for the building application.
Solution Approach 2:
The combination of regolith and TiO2 creates a composite material with optimized mechanical properties. The composite structure provides sufficient strength despite the presence of voids, as the material composition and interlocking design compensate for the reduced density.
4Ease of manufacture
If interlockable bricks are manufactured using 3D printing with in-situ materials, then ease of manufacture is improved, but manufacturing precision may worsen
Solution Approach 1:
The building system uses standardized modular bricks with tolerance-built interlocking features. By segmenting the structure into discrete units with standardized dimensions and built-in tolerance accommodation, the system achieves sufficient precision for structural assembly without requiring ultra-precise manufacturing, making 3D printing with in-situ materials feasible.
