Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for checking the producibility of composite security designs on production equipment are inadequate as they fail to accurately replicate the variations that occur during actual production, leading to potential issues being identified too late in the process.
Innovation Solution
A digital computer environment is used to simulate the production of composite security designs on specific production equipment, allowing for the evaluation of producibility by modeling the equipment and simulating production operations, including variations in design features and production conditions, to anticipate and address potential issues before actual production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing methods are used to check producibility, then the checking process is simple, but the accuracy of replicating production variations is insufficient
Solution Approach 1:
The patent creates a virtual copy of the production equipment and process in a computer environment. The production equipment is modeled as a virtual representation that can be simulated without physical intervention. This virtual copy includes all relevant parameters, constraints, and variations of the actual equipment, allowing accurate replication of production processes and variations for checking producibility.
Solution Approach 2:
The patent introduces a computer environment as an intermediary between the design phase and actual production. This intermediary system includes virtual models of equipment, digital representations of design features, and simulation algorithms that bridge the gap between theoretical design and physical production, enabling accurate assessment of producibility without direct physical testing.
2Reliability
If production variations are not accurately replicated, then the simulation process is fast, but potential production issues are identified too late
Solution Approach 1:
The patent performs all necessaryproducibility checks and variation simulations before actual production begins. By conducting virtual testing and assessment in advance, the system identifies potential issues beforehand, allowing corrective actions to be taken prior to physical production. This eliminates the need for time-consuming physical test samples and prototypes while ensuring reliable assessment.
3Manufacturing precision
If a detailed model of production equipment is created, then the simulation accuracy is high, but the system complexity increases
Solution Approach 1:
The patent divides the production equipment model into separate functional modules and components. Each module represents a specific part of the production process or equipment function, allowing detailed modeling of critical elements while keeping the overall system manageable. This segmentation enables high precision simulation of specific processes without requiring complete modeling of entire production systems.
Solution Approach 2:
The patent uses adjustable parameters and variables within the computer environment to control simulation accuracy. Instead of requiring all possible details to be modeled, the system allows users to adjust the level of detail and precision for specific parameters based on the checking requirements. This enables high precision when needed while maintaining system simplicity for routine checks.

AI summary
There is described a method of checking producibility of a composite security design of a security document, in particular of a composite banknote design, on a line of production equipment, the composite security design being the product of a combination of multiple sets of design features that are to be provided on a substrate as a result of a plurality of successive production operations carried out by means of the line of production equipment. The method comprises the steps of (a) providing digital design data representative of the composite security design of the security document, (b) modelizing, in a computer environment, the line of production equipment by means of which the composite security design is intended to be produced, (c) performing a computer simulation of production results of the plurality of successive production operations on the basis of the digital design data and the modelized line of production equipment, and (d) evaluating the computer simulated production results and determining, on the basis of these computer simulated production results, whether the composite security design can be produced on the line of production equipment.
