Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If silver ink is directly printed on polymer compound substrate, then the plate can be manufactured with simple process, but the particle texturing feel decreases luminance and sense of depth
Solution Approach 1:
The patent divides the single-layer silver ink structure into multiple separate layers: a primer layer for color implementation, a UV curable resin layer with fine pattern for depth effect, and a metal nanoparticle layer for luminance enhancement. This segmentation allows each layer to perform its specific function optimally without the drawbacks of direct silver ink printing.
Solution Approach 2:
The patent uses composite materials by combining different types of layers with distinct functions: polymer compound substrate, primer layer, UV curable resin layer, and metal nanoparticle layer. This composite structure achieves both high luminance and sense of depth while maintaining manufacturing feasibility through sequential layering.
2Ease of manufacture
If silver ink is directly printed on polymer compound substrate, then the manufacturing process is simple, but the plate lacks luxurious appearance and sense of depth
Solution Approach 1:
The patent separates the functions of color, depth, and luminance into distinct layers. The UV curable resin layer with fine pattern specifically addresses the sense of depth requirement through its microlens array structure, while other layers handle color and luminance separately.
Solution Approach 2:
The patent introduces a new dimension by creating a three-dimensional fine pattern structure within the UV curable resin layer. This microlens array structure adds vertical dimensionality and optical path complexity, generating the sense of depth without complicating the overall manufacturing process.
3Illumination intensity
If deposition method is used to achieve luxurious appearance, then the plate has high luminance and depth, but the manufacturing cost is high
Solution Approach 1:
The patent uses printing methods to create copies of the desired optical effects rather than relying on expensive deposition processes. The fine pattern in the UV curable resin layer copies the optical functionality of deposition, and the metal nanoparticle layer copies the luminance effect, both through more cost-effective printing techniques.
Solution Approach 2:
The patent changes the manufacturing parameters from deposition (high cost) to printing methods (lower cost). By using screen printing or inkjet printing to apply the metal nanoparticle layer and UV curable resin layer, the manufacturing cost is reduced while maintaining the luminance and depth effects through careful control of layer parameters.
