Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heterogeneous contact manner is used to combine structural layers, then manufacturing process is simplified, but bonding strength and structural stability deteriorate
Solution Approach 1:
The patent introduces a transition layer with gradually changing material composition and refractive index between the substrate and functional layers. This gradient structure changes the physical parameters continuously rather than abruptly, enabling homogeneous contact that improves bonding strength while maintaining manufacturing feasibility through controlled material deposition.
Solution Approach 2:
The transition layer is constructed as a composite material system combining multiple materials with different properties in a graded manner. This composite structure integrates the advantages of different materials while eliminating the abrupt interface problems, achieving both strong bonding and optical functionality.
2Ease of manufacture
If heterogeneous contact manner is used to combine structural layers, then manufacturing process is simplified, but structural stability and service life deteriorate
Solution Approach 1:
By implementing a gradient transition layer where material composition, density, and refractive index change continuously from the substrate to the functional layer, the patent eliminates abrupt interfaces that cause stress concentration and delamination. This parameter gradient approach significantly improves structural stability and extends service life while keeping the manufacturing process manageable.
3Device complexity
If conventional stacked structures are used, then device complexity is reduced, but energy consumption increases due to plasmon loss
Solution Approach 1:
The transition layer with gradually changing refractive index parameters reduces plasmon energy loss by creating a smooth optical impedance matching between the metal substrate and dielectric functional layers. This prevents abrupt plasmon decay at sharp interfaces, reducing energy loss while maintaining relatively simple device structure.

AI summary
A microstructure with high bonding strength includes a substrate, a deposition layer, and a first dielectric layer. The substrate has a first surface. The first surface has a covered area and an exposed area. The deposition layer has a plurality of nanoscale metal particles. The deposition layer is disposed on the covered area of the first surface. The exposed area is exposed from the deposition layer. The deposition layer has a bonding face on one side away from the first surface. The first dielectric layer is disposed on the bonding face and contacts the exposed area. With the connection structure between the first dielectric layer and the exposed area of the substrate, a hotspot structure formed by the deposition layer and the first dielectric layer is more stably fixed to the substrate, thereby improving bonding strength of the overall structure.
