Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current porous materials lack uniformity at a small volume scale, leading to nonuniform properties such as strength and elastic modulus, which affects their performance.
Innovation Solution
A highly uniform porous material with evenly distributed pores at any unit-level volume, ensuring that the elastic modulus is reduced by 10-99% compared to the raw material, achieved by classifying pores into different levels and controlling their distribution to maintain consistent mass across three-dimensional blocks of various sizes.

Engineering Contradiction Analysis
1Manufacturing precision
If porous materials are prepared with conventional methods, then they can be produced with relatively simple processes, but the pore distribution is nonuniform at small volume scale leading to inconsistent material properties
Solution Approach 1:
The invention divides the porous material structure into repeating unit cells with controlled pore arrangements. By segmenting the material into standardized units, uniform pore distribution is achieved at small scales while maintaining manufacturability through modular construction approaches.
Solution Approach 2:
The invention implements specific pore size and distribution characteristics at local unit cell levels to ensure uniform material properties. Each unit cell is designed with controlled pore geometry, and the local structural quality is optimized to achieve consistent macroscopic behavior across the entire material.
2Stability of the object's composition
If the pore size and distribution are made uniform throughout the material, then the material properties become consistent, but the elastic modulus cannot be sufficiently reduced
Solution Approach 1:
The invention introduces asymmetric pore arrangements and non-uniform pore size distributions within the unit cell structures. This controlled asymmetry allows the material to maintain consistent macroscopic properties while achieving lower elastic modulus through optimized local structural configurations that do not compromise overall uniformity.
Solution Approach 2:
The invention systematically varies pore size, pore shape, and pore distribution parameters within controlled ranges to optimize the balance between material consistency and elastic modulus reduction. By adjusting these structural parameters, the material achieves both uniform properties and reduced stiffness as required.
