Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods are used to apply precious metals, then production speed is maintained, but manufacturing precision deteriorates due to variations in metal quantity
Solution Approach 1:
The metallic layer is divided into multiple sublayers, each deposited in separate steps with controlled thickness. This segmentation allows precise control of the total precious metal quantity while maintaining production efficiency through systematic deposition processes.
Solution Approach 2:
A transparent transition layer is deposited on the substrate before depositing the precious metal layer. This preliminary action prepares the surface for precise metal deposition and enables accurate control of metal quantity while maintaining production speed.
2Reliability
If transparent substrates are used to display precious metals, then visual verification is improved, but security against counterfeiting deteriorates
Solution Approach 1:
Different regions of the laminate have different properties: the transition layer has specific optical characteristics, the metallic layer has precise thickness variations, and security features are localized in specific areas. These local quality differences create verifiable authentication characteristics that prevent counterfeiting while allowing visual verification.
Solution Approach 2:
The laminate combines multiple materials with distinct properties: transparent substrates, transition layer with specific optical properties, and precious metal layers. This composite structure creates unique optical effects and security features that are difficult to replicate, simultaneously enabling verification and preventing counterfeiting.
3Manufacturing precision
If multiple sublayers with varying thicknesses are deposited, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The transparent transition layer acts as an intermediary between the substrate and the precious metal layers. It facilitates precise deposition control and enables the formation of multiple sublayers with varying thicknesses while managing the complexity of the deposition process.
Solution Approach 2:
The deposition process controls parameters such as layer thickness, material composition, and deposition rate to achieve precise control over the metallic layer structure. By systematically varying these parameters across multiple sublayers, high manufacturing precision is achieved while the process remains manageable.
