Security Document Scanning with Elastic Securing Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security document verification systems require manual handling of documents during insertion, which is inconvenient and lacks secure fixation on the support during scanning.
Innovation Solution
A device with elastically deformable securing elements, such as brushes, that secure the document on the support after manual insertion, preventing removal without overcoming a securing force, and a detachable cover with magnetic fastening for easy replacement and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual insertion of security document is used, then ease of operation is improved, but document securing during scanning deteriorates
Solution Approach 1:
The securing element is designed to be dynamically deformable, transitioning between a first state during manual insertion (allowing easy document placement) and a second state during scanning (providing secure fixation). The elastic or shape memory material enables automatic state change based on the applied force, resolving the contradiction between ease of insertion and secure holding.
Solution Approach 2:
The securing element changes its physical parameters (shape, stiffness, or position) in response to applied force. During manual insertion, the element deforms to accommodate the document, then automatically returns to or transitions to a securing configuration that firmly holds the document during scanning, thus achieving both easy operation and reliable securing.
2Reliability
If document is manually held during scanning, then document securing is improved, but ease of operation deteriorates
Solution Approach 1:
The securing element is designed to automatically perform the securing function without requiring continuous manual intervention. After the user places the document during manual insertion, the elastic or shape memory material self-activates to secure the document in place, enabling hands-free scanning while maintaining reliable document fixation.
3Extent of automation
If mechanical retraction means are used, then automation is improved, but device complexity deteriorates
Solution Approach 1:
The patent extracts the complex mechanical retraction mechanism from the device and replaces it with a simpler elastic or shape memory material-based securing element. This element provides automatic document handling and securing functionality without requiring complex motors, gears, or control systems, thus maintaining automation benefits while reducing device complexity.
Solution Approach 2:
The patent substitutes complex mechanical retraction systems with materials that utilize elastic deformation or shape memory effects. This replacement achieves automatic document securing and positioning using material properties rather than mechanical components, reducing device complexity while maintaining or improving automation functionality.
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
Ensures secure and hands-free document scanning by automatically fixing the document on the support, allowing for convenient manual insertion and preventing accidental removal, with the option for cover customization and easy maintenance.
Implementation Method 1
correcting elements that include elastic deformation parts with which the security document inserted into the insertion opening comes into contact and that correct the conveying direction of the security document inserted from the insertion opening using the elastic force exerted by the elastic deformation parts
Implementation Method 2
a first magnet arranged in the cover and a second magnet arranged in the housing, wherein the first and second magnets are arranged such that a magnetic attraction force between the first and second magnets enables the cover to be fixed and/or mounted on the housing
Implementation Method 3
Friction wheels or friction belts can also be used for mechanical transport of the security document
