Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for inspecting identity documents are laborious and time-consuming, leading to long queues and decreased security and reliability, and they require a traditional kiosk station with network and power connections, limiting their portability and ease of use.
Innovation Solution
A portable inspection apparatus with a movable linear image sensor, RFID device, and data control means that allows for one-handed operation, enabling authentication of identity documents without moving the document, using a CCD or CMOS sensor to read codes and compare information from RFID tags and printed codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional kiosk station apparatuses are used for inspecting identity documents, then inspection operations can be performed, but the operations become long and laborious causing long queues and decreased security reliability
Solution Approach 1:
The inspection process is segmented into distinct functional modules: RFID reading module, optical scanning module, and data comparison module. These can operate independently and in parallel, with the RFID device reading tag information while the linear sensor scans printed codes simultaneously, eliminating sequential processing delays
Solution Approach 2:
The apparatus performs preliminary actions by pre-positioning the RFID antenna and linear sensor in the reading area, and pre-loading authentication algorithms into the data control means. This allows immediate inspection upon document placement without setup delays
2Adaptability or versatility
If traditional kiosk station apparatuses are used for inspecting identity documents, then inspection operations can be performed, but the apparatus requires network connection and power supply connections reducing portability
Solution Approach 1:
The invention extracts the essential inspection functions (RFID reading, optical scanning, data comparison) from the traditional kiosk infrastructure and consolidates them into a self-contained portable apparatus with integrated power supply and processing capabilities, eliminating dependence on external network and power connections
Solution Approach 2:
The portable apparatus is designed as a universal inspection device that can operate independently of specific infrastructure (no network or power connections required), making it adaptable to various locations including mobile security checkpoints, airports, and border control points
3Ease of operation
If document scanning is performed by moving the document, then code reading can be achieved, but the operation becomes more complex and harder to handle
Solution Approach 1:
Instead of moving the document to scan the code, the invention inverts the approach by keeping the document stationary and moving the linear sensor across the document surface. This allows the operator to simply place the document on the reading area without complex manipulation
Solution Approach 2:
The invention replaces the mechanical action of manually moving the document with an automated linear sensor that scans across the stationary document. The motor means automatically positions and moves the sensor, eliminating the need for manual document handling during scanning
