Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security elements are vulnerable to unauthorized reproduction due to their complexity in manufacturing processes, necessitating enhanced forgery resistance.
Innovation Solution
A security element with a carrier featuring a motif region comprising a first micro-optic representation arrangement presenting different images in viewing angle-dependent fashion and a second micro-optic representation arrangement simulating a bulged reflective surface, requiring distinct manufacturing processes for each, thus increasing forgery resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single micro-optic representation arrangement is used, then the manufacturing process is simpler, but the forgery resistance is lower
Solution Approach 1:
The security element is divided into two distinct motif parts (first and second motif parts), each containing a different micro-optic representation arrangement. This segmentation allows each part to be manufactured using optimized processes while collectively providing enhanced forgery resistance that neither part could achieve alone.
Solution Approach 2:
The patent combines two different micro-optic representation arrangements (e.g., holographic elements and diffractive elements, or embossed and non-embossed structures) into a single composite security element. This composite structure integrates multiple manufacturing techniques, creating a security feature that is difficult to forge while maintaining visual coherence as a unified motif.
2Ease of manufacture
If two different micro-optic representation arrangements are used, then the optical attractiveness and recognition value increase, but the manufacturing complexity increases
Solution Approach 1:
Two micro-optic representation arrangements that would normally require separate manufacturing processes are merged into a single integrated security element with a unified motif design. The first and second motif parts are positioned adjacent to each other and work together to create a cohesive visual representation, enhancing optical attractiveness while consolidating manufacturing steps.
Solution Approach 2:
The security element is designed to perform multiple functions simultaneously: it provides authentication through different micro-optic arrangements, creates visual appeal through varied optical effects, and maintains a unified aesthetic appearance. The motif region serves as both a decorative element and a security feature, combining multiple functions in a single structure.
3Ease of operation
If the two motif parts are arranged contiguously, then the user perceives a single unified motif, but the positioning precision requirement increases
Solution Approach 1:
The first and second motif parts are arranged in a nested or interlocking configuration where they fit together to form a complete motif. This nesting approach ensures proper alignment and creates a unified visual appearance, as the boundaries between the two parts are minimized and integrated into the overall design.
Solution Approach 2:
The patent utilizes spatial arrangement in multiple dimensions to position the first and second motif parts relative to each other. By carefully controlling the spatial relationship and orientation of the two parts, the design achieves a unified visual appearance while accommodating the precision requirements through three-dimensional positioning strategies.
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 security element provides high optical attractiveness and recognition value, making it difficult for forgers to replicate, as they must master both manufacturing processes and position the motifs accurately, enhancing authenticity verification.
Implementation Method 1
a first micro-optic representation arrangement which presents at least two different images in viewing angle-dependent fashion as a first motif part
Implementation Method 2
a micro-optic representation arrangement in the form of a moire magnification arrangement
Implementation Method 3
a second micro-optic representation arrangement which presents a reflective surface as a second motif part, which surface appears bulged relative to the actual macroscopic spatial form of the second micro-optic representation arrangement
