Engineering Contradiction Analysis
1Ease of manufacture
If poly-based resin is used in conventional dry heating panels, then construction is simplified and construction time is reduced, but thermal conductivity deteriorates and heating efficiency decreases
Solution Approach 1:
The patent uses a composite material consisting of carbon fiber reinforced polymer resin. The carbon fiber provides high thermal conductivity while the polymer resin maintains construction simplicity. This composite structure allows the panel to be easily constructed like conventional poly-based panels while achieving superior thermal conductivity comparable to metal sheets.
2Ease of manufacture
If poly-based resin is used in conventional dry heating panels, then construction cost is reduced, but heat storage capacity decreases and flame retardancy is poor
Solution Approach 1:
The carbon fiber reinforced polymer composite provides both cost-effectiveness and enhanced safety properties. The carbon fiber addition improves flame retardancy significantly compared to conventional poly-based resin, while the overall construction cost remains lower than metal sheet solutions due to the polymer matrix providing the base structure.
3Temperature
If metal sheet is used on the upper plate to secure thermal conductivity, then thermal conductivity is improved, but heat storage capacity is low and indoor air is dried
Solution Approach 1:
The carbon fiber reinforced polymer composite combines the thermal conductivity benefits of metal with the heat storage capacity of polymer materials. The carbon fiber network provides efficient heat conduction pathways, while the polymer matrix retains its ability to store thermal energy, avoiding the overheating and air drying issues associated with metal sheets.
4Device complexity
If conventional dry heating panel with poly-based resin is used, then construction is simplified, but the panel is vulnerable to fire due to low flame retardancy
Solution Approach 1:
The carbon fiber reinforcement transforms the flame retardancy properties of the polymer composite. Carbon fiber is inherently fire-resistant and creates a protective char structure that slows combustion, significantly improving the flame retardancy of the panel while maintaining the construction simplicity of a single integrated panel structure.
