Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security features with luminescent components for value documents are difficult to analyze and distinguish from camouflage components, as they share similar chemical elements, making it challenging to prevent replication or imitation.
Innovation Solution
A security feature with a luminescent component and a camouflage component, where the camouflage component uses chemical elements with similar structural properties to the luminescent component, but with different chemical elements, making it harder to analyze and replicate the luminescent component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If the camouflage component uses the same chemical elements as the luminescent component, then the camouflage effect is improved, but the analyzability of the luminescent component is improved instead of hindered
Solution Approach 1:
The patent applies local quality by using chemical elements with similar structural properties (e.g., same group in periodic table) but different identities in the camouflage component compared to the luminescent component. This creates local differentiation at the elemental level while maintaining overall structural similarity, preventing identification of the luminescent component's specific composition without compromising the camouflage effect.
Solution Approach 2:
The patent changes the chemical identity parameter of elements while maintaining similar structural properties. By selecting elements from the same periodic table group (e.g., using Al instead of Ga, or Mg instead of Zn), the patent alters the chemical composition parameter to prevent identification while preserving the structural framework that provides camouflage.
2Difficulty of detecting and measuring
If the camouflage component uses chemical elements with similar structural properties but different chemical identity, then the difficulty of analyzing the luminescent component is increased, but the material identity camouflage is reduced
Solution Approach 1:
The patent applies local quality by using chemical elements with similar structural properties (e.g., same group in periodic table) but different identities in the camouflage component compared to the luminescent component. This creates local differentiation at the elemental level while maintaining overall structural similarity, preventing identification of the luminescent component's specific composition without compromising the camouflage effect.
3Ease of operation
If conventional analytical methods are used to identify the luminescent component, then the identification process is simplified, but the security feature can be easily replicated
Solution Approach 1:
The patent changes the chemical identity parameter of elements while maintaining similar structural properties. By selecting elements from the same periodic table group (e.g., using Al instead of Ga, or Mg instead of Zn), the patent alters the chemical composition parameter to prevent identification while preserving the structural framework that provides camouflage.
Solution Approach 2:
The patent applies partial action by providing enough structural similarity to maintain camouflage effectiveness while introducing sufficient chemical element differences to prevent complete identification. The camouflage component contains elements that are similar enough to maintain the overall structure and appearance but different enough to prevent exact replication through analysis.
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 use of a camouflage component with similar structural properties significantly increases the difficulty of analyzing the luminescent component, making it nearly impossible to replicate the security feature with conventional analysis methods.
Implementation Method 1
upon appropriate excitation, they exhibit one or more characteristic narrow-band luminescences
Implementation Method 2
The emission of the luminophores used is also referred to as luminescence; this can include fluorescence and/or phosphorescence
Implementation Method 3
The emission of the luminophores used is also referred to as luminescence; this can include fluorescence and/or phosphorescence
Implementation Method 4
in addition to the aforementioned luminescence, so-called energy transfer processes can be observed, which can lead to more complex emission spectra. In these energy transfer processes, one ion can transfer its energy to another
