Movable Mirror Alignment for Multi-Tilt Security Document Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document processing systems for security documents, such as those using tilt images, are time-consuming and costly due to the need for frequent conversion and recalibration of mirror arrangements when applying multiple or different tilt images, requiring the document to be removed and repositioned.
Innovation Solution
A document processing system with a document carrier device and movable mirror arrangements that allow for the application of different tilt images without removing the document, using a first and second mirror arrangement that can be moved and aligned to direct radiation at specific angles, enabling the creation of both MLI and CLI tilt images without conversion, and incorporating a heating device for improved processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mirror arrangements are converted and recalibrated to apply different tilt images, then the ability to apply multiple tilt images (MLI and CLI) is improved, but the processing time increases and productivity decreases
Solution Approach 1:
The patent applies the dynamics principle by making the mirror arrangement movable rather than fixed. The mirror can be positioned at different locations (first location for MLI, second location for CLI) and adjusted dynamically during operation. This allows the system to switch between different tilt image types without physical conversion or recalibration, thereby maintaining high productivity while providing versatility in applying multiple tilt images.
2Manufacturing precision
If the document is removed and repositioned to apply different tilt images, then the correct application of security features is improved, but the processing time increases and loss of time occurs
Solution Approach 1:
The patent applies preliminary action by pre-positioning the mirror at appropriate locations for different tilt image types. The mirror can be adjusted to the first location before applying MLI or to the second location before applying CLI, all while the document remains in place. This eliminates the need for document removal and repositioning, saving time while ensuring correct application of security features through proper mirror positioning.
3Adaptability or versatility
If mirror arrangements are frequently converted for different tilt images, then the versatility of the system is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a single mirror arrangement that can serve multiple functions by being positioned at different locations. The same mirror structure is used for both MLI and CLI applications, eliminating the need for separate mirror arrangements or complex conversion mechanisms. This multi-functional approach maintains versatility while minimizing device complexity.
