Engineering Contradiction Analysis
1Object-affected harmful factors
If cement is used as a building material, then structural needs are met, but ecological footprint increases due to CO2 production
Solution Approach 1:
The patent creates a composite material combining cement with conductive carbon nanoparticles (such as carbon black or graphite). This composite maintains the structural properties of cement while adding electrical conductivity functionality, allowing the material to serve dual purposes and reduce the need for separate heating elements, thereby reducing overall ecological footprint.
Solution Approach 2:
The patent modifies the electrical conductivity parameter of cement by incorporating carbon nanoparticles. This parameter change transforms cement from an insulating material to a conductive one, enabling new applications such as heated pavements and freeze-thaw protection without requiring additional materials.

If conventional cement is used, then manufacturing is simple, but energy storage capabilities are lacking
Solution Approach 1:
The patent makes cement multi-functional by incorporating conductive carbon nanoparticles, enabling it to simultaneously provide structural support, electrical conductivity, and energy storage capabilities. This eliminates the need for separate heating elements or energy storage systems, reducing overall system complexity despite the modified material composition.
