Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multilayer paint systems are used to achieve sufficient chromaticity and metallic flop, then optical performance is improved, but manufacturing cost increases and equipment compatibility deteriorates
Solution Approach 1:
The patent segments the optical device into distinct functional layers: a reflector layer and separate selective light modulator layers. This segmentation allows each layer to be optimized independently and deposited using standard vacuum deposition techniques, achieving high optical precision without requiring complex multilayer paint systems.
Solution Approach 2:
The patent replaces mechanical paint application systems with vacuum deposition technology. This substitution enables precise control of layer thickness and composition at the nanometer scale, achieving superior optical precision while using equipment that is already standard in the semiconductor and optical industries.
2Ease of manufacture
If conventional manufacturing methods are used, then equipment compatibility is maintained, but chromaticity and metallic flop are insufficient
Solution Approach 1:
The patent changes the deposition parameters and layer composition to achieve superior chromaticity. By controlling the thickness and material composition of the selective light modulator layers during vacuum deposition, the patent achieves precise control over optical properties while using equipment that is already widely available in the industry.
Solution Approach 2:
The patent employs composite material structures combining reflector materials with selective light modulator materials. This composite approach enables the achievement of high chromaticity and metallic flop effects while using deposition processes that are compatible with standard manufacturing equipment.
3Device complexity
If simpler single-layer structures are used, then manufacturing cost is reduced, but optical performance (chromaticity and metallic flop) is insufficient
Solution Approach 1:
The patent transitions from two-dimensional planar structures to three-dimensional layered architectures. By stacking the reflector layer with selective light modulator layers on opposite surfaces, the patent creates vertical optical pathways that enhance chromaticity and metallic flop effects while maintaining relatively simple manufacturing processes.
