Document Feeder Card Reader Wireless Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses lack a secure and user-friendly method for authenticating users, especially in public facilities where installing authentication devices is difficult or not feasible.
Innovation Solution
An image reading device with a document feeder and card reader that allows for non-contact IC card authentication, where the card reader can be easily attached or removed and communicates wirelessly, facilitating user authentication while maintaining a compact and user-friendly design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an authentication device is installed in an image forming apparatus, then security is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The authentication device is separated from the main image forming apparatus and integrated into the document feeder unit instead. This segmentation allows the authentication function to be added without increasing the complexity of the main apparatus, while still providing security enhancement through a dedicated authentication module in the document feeder.
2Reliability
If an authentication device is permanently installed, then security is improved, but ease of operation and flexibility deteriorate
Solution Approach 1:
The document feeder unit with integrated authentication device can be dynamically attached or detached from the image forming apparatus. This dynamic configuration allows users to easily operate the system by simply connecting or disconnecting the document feeder, providing flexibility while maintaining security when the authentication function is needed.
3Adaptability or versatility
If a card reader is attached to a document feeder, then authentication functionality is improved, but risk of wire damage during attachment increases
Solution Approach 1:
The card reader is connected to the document feeder unit through wireless communication instead of physical wire connections. This substitution eliminates the risk of wire damage during attachment and detachment operations, while still providing robust authentication functionality through non-contact IC card reading.
4Reliability
If authentication device is integrated into main unit, then security is improved, but adaptability to different settings deteriorates
Solution Approach 1:
The document feeder unit serves multiple functions: it acts as both a document feeding mechanism and an authentication device housing. This multi-functional design allows the authentication capability to be easily adapted to different settings and locations, as the entire document feeder unit can be positioned flexibly while maintaining security 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
Enhances security and user convenience by enabling secure authentication without the need for constant authentication device installation, allowing for flexible use in various settings while preventing issues like wire damage during attachment.
Implementation Method 1
an IC card reader/writer reading, in a non-contact state, information stored in an IC card being an information recording medium adjacent from the outside and electromagnetically connected
