Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ink-based displays or relief structures are used, then visual effects can be achieved, but the counterfeiting resistance and designability are insufficient
Solution Approach 1:
The patent changes the optical parameters by controlling the refractive index of the dielectric layer (1.0 < n ≤ 2.0) and the elevation angle of inclined surfaces (α), creating direction-dependent visual effects that are difficult to replicate and highly designable
Solution Approach 2:
The patent combines dielectric materials with specific refractive indices and surface structures to create a composite system that achieves both high counterfeiting resistance and designability through optical anisotropy
2Illumination intensity
If the dielectric layer has high refractive index to suppress reflection, then reflection suppression is improved, but the material selection and manufacturing complexity increase
Solution Approach 1:
The patent optimizes the refractive index parameter to a specific range (1.0 < n ≤ 2.0) that balances reflection suppression effectiveness with material availability and manufacturing feasibility, avoiding the need for extremely high refractive index materials
3Illumination intensity
If inclined surfaces are added to the dielectric layer to reflect light in oblique direction, then visual effect is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a reasonable elevation angle range (0° < α < 90°) for the inclined surfaces that achieves effective light reflection control while remaining compatible with conventional manufacturing processes, avoiding excessively precise angular requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides new visual effects by suppressing reflection in one direction while reflecting light in another, making the product appear darker or brighter depending on the viewing angle, thus enhancing resistance to counterfeiting and designability.
Implementation Method 1
the inclined surfaces reflect incident light incident on the dielectric layer and which emerges as reflected light
Implementation Method 2
