Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive geotextile with multiple layers is used, then conductivity is achieved, but installation becomes complex and time-consuming
Solution Approach 1:
The patent combines the conductive function and structural support function into a single integrated mesh layer. The mesh itself is made conductive through carbon mixing in the plastic material, eliminating the need for separate conductive wire layers and carrier textiles. This merging of functions directly resolves the contradiction by maintaining conductivity while simplifying the overall structure to a single layer that is easier to install.
Solution Approach 2:
The patent uses composite material technology by mixing carbon particles into the plastic matrix to create a conductive plastic mesh. This composite approach provides both the mechanical strength of plastic and the electrical conductivity of carbon, achieving the conductive function without requiring delicate metal wire layers that need protective carrier textiles, thus simplifying installation.
2Reliability
If conductive geotextile with protective layers is used, then conductivity is maintained, but installation time increases
Solution Approach 1:
The conductive mesh integrates the conductive function directly into the structural layer, eliminating the need for separate protective carrier layers. The mesh is self-supporting and can be installed directly without the time-consuming process of handling and protecting delicate conductive elements, thus reducing installation time while maintaining conductivity.
Solution Approach 2:
The conductive mesh is designed to be self-supporting and self-protecting. The plastic mesh structure inherently protects the carbon conductive network without requiring additional carrier textiles. This self-service design eliminates the time-consuming steps of installing and protecting separate layers, allowing for faster installation.
3Reliability
If delicate conductive geotextile is used, then conductivity is achieved, but installation becomes difficult in adverse weather
Solution Approach 1:
By using composite material technology with carbon mixed in plastic, the patent creates a conductive mesh that has both electrical conductivity and mechanical robustness. The plastic matrix provides weather resistance and structural integrity, while the carbon provides conductivity. This composite structure is not delicate like metal wire geotextiles and can be easily installed in adverse weather conditions.
Solution Approach 2:
The patent changes the material parameters by using carbon-filled plastic instead of metal wires. This parameter change transforms the conductive element from a delicate, weather-sensitive material to a robust, weather-resistant material that maintains its properties in adverse conditions, significantly improving ease of installation.
4Reliability
If multi-layer conductive geotextile is used, then conductivity is provided, but connection process becomes complex
Solution Approach 1:
The patent merges all conductive functions into a single mesh layer, eliminating multiple layers that would need to be connected. The single-layer design means connections are made directly between mesh points without the complexity of aligning and connecting multiple layers, significantly simplifying the connection process while maintaining conductivity.
