Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If complex carbon capture machinery and equipment are used, then carbon dioxide capture efficiency is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the carbon capture function from complex machinery and embeds it directly into building materials through MOF integration. The MOF material is incorporated into concrete, bricks, or facade panels, allowing the building structure itself to perform carbon capture without separate capture equipment.
Solution Approach 2:
The building materials themselves perform the carbon capture function autonomously. The MOF-containing materials automatically adsorb CO2 from the environment without requiring external power, control systems, or maintenance, making the building self-sufficient for carbon sequestration.
2Quantity of substance
If traditional carbon capture facilities are installed, then carbon dioxide storage capability is improved, but ease of manufacture and installation deteriorates
Solution Approach 1:
The patent merges the carbon storage function with常规 building materials. The MOF is integrated into concrete mixtures, brick formulations, or facade panel compositions, combining structural functionality with carbon capture in a single material system that requires no separate installation.
Solution Approach 2:
The invention uses composite materials consisting of conventional construction materials combined with MOF components. This allows the benefits of both material types to be achieved - the structural properties of concrete/bricks and the carbon capture capabilities of MOF - in a unified material that maintains ease of manufacture.
3Quantity of substance
If building structures are modified to incorporate carbon capture technology, then carbon adsorption capability is improved, but ease of operation and structural integrity deteriorates
Solution Approach 1:
The carbon capture functionality is built into the building materials during their initial manufacture or fabrication. MOF-containing concrete is poured, MOF bricks are laid, or MOF panels are installed as part of the standard construction process, eliminating the need for later modifications to existing structures.
Solution Approach 2:
The MOF is uniformly distributed within the building material matrix, creating a homogeneous composite where carbon capture capability is evenly throughout the material. This ensures consistent performance while maintaining the material's structural homogeneity and integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composite material provides an innovative, cost-effective, and environmentally friendly method for carbon sequestration, enhancing existing construction materials with carbon adsorption capabilities and making carbon capture technology accessible to building owners without significant structural changes or equipment installation.
Implementation Method 1
The metal-organic framework is configured to/has the ability to adsorb carbon dioxide (exhibits adsorption of carbon dioxide). CO 2 adsorption by MOFs is associated to the inherent microporous nature of this type of materials. The intrinsing property of a MOF to adsorb carbon dioxide is attributed to the microporosity of such materials and the presence of open metal sites (OMS) within the pores of the MOF which facilitate CO 2 -OMS interactions.
Implementation Method 2
Being based on physisorbents, the amount of energy required for the regeneration of the material is lower than that of chemisorbents, another sorbent material.
