Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a metal reflective structure is added to improve brightness and uniformity, then luminance and brightness uniformity are improved, but device complexity increases
Solution Approach 1:
The patent combines the metal reflective structure directly with the circuit board by setting the circuit board as the substrate, merging two components into one integrated structure. This reduces the number of separate parts and assembly steps while maintaining the brightness improvement function.
Solution Approach 2:
The circuit board serves dual functions: as the electrical connection substrate and as the substrate for the metal reflective structure. This multi-functionality reduces overall device complexity by eliminating the need for a separate reflective structure substrate.
2Illumination intensity
If transparent materials are used in the protective layer to improve light reflection, then brightness is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a thickness range of 0.5-5.0 micrometers for the metal layer and uses transparent materials with specific optical properties in the protective layer. By defining parameter ranges rather than fixed values, the design accommodates manufacturing variations while maintaining brightness improvement.
Solution Approach 2:
The protective layer uses transparent materials that combine optical clarity with protective properties. This composite approach allows the layer to fulfill multiple functions (protection and light transmission) without requiring extremely tight manufacturing tolerances.
3Illumination intensity
If the metal layer thickness is increased to improve reflectivity, then brightness uniformity is improved, but power consumption increases
Solution Approach 1:
The patent optimizes the metal layer thickness to a specific range (0.5-5.0 micrometers) that provides sufficient reflectivity for brightness uniformity while avoiding excessive thickness that would increase power consumption. This parameter optimization balances optical performance with energy efficiency.
Solution Approach 2:
The patent applies partial action by using a thin metal layer (0.5-5.0 micrometers) that provides just enough reflectivity to achieve brightness uniformity without the excessive thickness that would cause unnecessary power consumption. This avoids over-engineering the solution.
