Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate layers are used for heat dissipation, electromagnetic wave shielding, and light blocking, then each function can be optimized independently, but the device structure becomes complex and manufacturing cost increases
Solution Approach 1:
The patent combines heat dissipation filler, electromagnetic wave shielding filler, and light blocking filler into a single resin coated layer applied to the back surface of the substrate. This merging of multiple functional fillers into one integrated layer achieves the desired functional performance while simplifying the overall device structure and reducing manufacturing complexity compared to using separate layers for each function.
Solution Approach 2:
The resin coated layer is designed to perform multiple functions simultaneously: heat dissipation through thermally conductive filler, electromagnetic wave shielding through conductive or magnetic filler, and light blocking through pigmented filler. This multi-functional approach allows a single layer to replace what would traditionally require multiple separate layers, thereby reducing structural complexity while maintaining comprehensive functional performance.
2Ease of manufacture
If a simplified single-layer structure is used, then manufacturing process is simplified and cost is reduced, but achieving all functions (heat dissipation, shielding, light blocking) in one layer is difficult
Solution Approach 1:
The resin coated layer employs a composite material system comprising multiple types of fillers (heat dissipation filler, electromagnetic wave shielding filler, and light blocking filler) dispersed in a resin matrix. This composite structure enables the single layer to achieve multiple functions simultaneously, making the simplified manufacturing process viable while maintaining comprehensive functional performance that would otherwise require multiple specialized layers.
Solution Approach 2:
Different regions or aspects of the resin coated layer are optimized for different functions through the strategic selection and distribution of specific fillers. The layer exhibits locally optimized properties: thermally conductive pathways for heat dissipation, conductive networks for electromagnetic shielding, and pigmented regions for light blocking, all within the single integrated layer structure.
