Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple conventional functional layers (PET, foam, graphene, copper foil) are attached to achieve protection, cushioning, and heat dissipation, then the required functional performance is improved, but the device structure becomes complicated and thickness increases
Solution Approach 1:
The patent combines multiple conventional functional layers (protection layer, cushioning layer, and heat dissipation layer) into a single integrated porous metal layer. This layer simultaneously provides mechanical protection through its metallic structure, cushioning through its porous architecture that absorbs impact energy, and heat dissipation through its high thermal conductivity metal composition, thereby eliminating the need for separate stacked layers and simplifying the overall device structure.
Solution Approach 2:
The porous metal layer is designed to perform multiple functions simultaneously: it serves as a protective barrier against external damage, provides cushioning through its energy-absorbing porous structure during impact events, and conducts heat away from sensitive components. This multi-functional design allows a single layer to replace what would traditionally require multiple specialized layers, reducing structural complexity while maintaining comprehensive functional performance.
2Reliability
If multiple conventional functional layers are attached to achieve protection, cushioning, and heat dissipation, then the required functional performance is improved, but the thickness and weight of the display panel increase
Solution Approach 1:

This layer simultaneously provides mechanical protection through its metallic structure, cushioning through its porous architecture that absorbs impact energy, and heat dissipation through its high thermal conductivity metal composition, thereby eliminating the need for separate stacked layers and simplifying the overall device structure.
Solution Approach 2:
The patent employs a porous metal layer where the porous structure provides cushioning functionality by absorbing impact energy through cell collapse and deformation. The metallic material provides protection and heat dissipation, while the porosity reduces overall material density and weight compared to solid metal layers. This porous architecture allows the layer to achieve multiple functions with reduced weight and thickness compared to using solid conventional materials stacked together.
