Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If carbon nonwovens with closed-surface structure are used for heating and stabilization, then good electrical conductivity and heating performance are achieved, but embedding into composite structures becomes difficult
Solution Approach 1:
The closed-surface carbon nonwoven structure is segmented into an open lattice grid structure with discrete openings. This segmentation allows the material to be embedded into composite structures while maintaining heating capability through the conductive coating on the lattice elements.
Solution Approach 2:
The invention transitions from a closed-surface structure to a porous open lattice structure with controlled openings (1x1 mm to 20x20 mm). This porous structure enables embedding into composite matrices while the conductive coating ensures heating functionality is preserved.
2Strength
If fiber tissue thickness is increased to improve mechanical strength, then reinforcement capability is enhanced, but overall structure height increases
Solution Approach 1:
The invention uses composite construction by coating the fiber lattice structure with electrically conductive materials. This composite approach provides both mechanical strength from the fiber lattice and heating functionality from the conductive coating, achieving high strength without increasing overall thickness.
Solution Approach 2:
The fiber lattice structure acts as a thin, flexible reinforcement layer that can be embedded within composite structures without significantly increasing height. The structure provides mechanical strength while maintaining a thin profile suitable for integration into wall and floor applications.
3Use of energy by moving object
If lattice openings are made larger to improve heat distribution, then heating efficiency is enhanced, but mechanical strength decreases
Solution Approach 1:
The invention optimizes the lattice opening parameters (size, shape, distribution) to achieve a balance between heat distribution and mechanical strength. The opening dimensions (1x1 mm to 20x20 mm) are specifically selected to allow adequate heat transfer while maintaining structural integrity through the fiber lattice framework.
