Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shared printer management systems rely on personal identification numbers (PINs) that can be easily compromised, requiring expensive security measures like iris or fingerprint recognition.
Innovation Solution
A system and method using RFID technology where an RFID transceiver unit periodically retrieves information from an RFID chip to determine task permission levels, controlling the printer based on user permissions and storing log information for user ID-specific printing counts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If PIN-based authentication is used for shared printer management, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent replaces the mechanical PIN-based authentication system with an RFID-based authentication system. The RFID chip embedded in the printer communicates wirelessly with RFID tags (such as business cards or badges) to authenticate users, eliminating the need for manual PIN entry and providing more secure identification through unique RFID identifiers.
Solution Approach 2:
The patent introduces an RFID chip as an intermediary component between the user and the printer authentication system. This RFID chip stores user identification information and communicates with the printer's control unit, serving as a secure mediator that verifies user permissions without requiring direct PIN input or complex biometric scanning.
2Reliability
If expensive security devices like iris or fingerprint recognition are used, then security is improved, but device complexity and cost are worsened
Solution Approach 1:
The patent employs inexpensive RFID tags (such as those on business cards or simple badges) as disposable or reusable authentication media. These RFID tags provide secure identification without requiring expensive biometric scanning equipment, achieving cost-effective security through widely available, low-cost RFID technology.
Solution Approach 2:
The patent substitutes complex biometric authentication systems (iris or fingerprint recognition) with a simpler RFID-based authentication mechanism. The RFID system uses wireless electromagnetic communication to verify user identity, eliminating the need for expensive optical sensors, image processing hardware, and complex authentication algorithms associated with biometric systems.
3Reliability
If RFID technology is used for printer management, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent integrates the RFID chip into the existing printer structure, allowing it to perform multiple functions: storing user authentication data, managing print job permissions, tracking printing history, and controlling printer operations. This multi-functionality reduces the need for separate security devices and minimizes overall system complexity despite adding RFID capabilities.
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 by using RFID technology to manage shared printers based on user permissions, reducing the need for expensive security devices and ensuring secure document output, while maintaining user ID-specific printing logs.
Implementation Method 1
information about all processes including manufacturing, distribution, management and consumption of products is stored in chip based RFID tags that are attached to the products to serve as transponders. The RFID tags transmit signals through an antenna. The signals are received by an RFID reader (transceiver)

AI summary
A system and method of managing a shared printer with radio frequency identification (RFID) includes at least one RFID chip containing information about task permission for users, an RFID transceiver unit to periodically retrieve information about the RFID chip, a controller to determine whether to output a document based on task permission held by a user associated with the RFID chip retrieved by the RFID transceiver unit, and a printing unit to form images on a printing medium in response to a control signal from the controller. It is possible to allow, for example, printing and facsimile transmission by giving specific permission to each user and allows a manager to inspect a use specification by the RFID transceiver unit. The RFID transceiver unit is included in a printer and periodically retrieves information about an RFID chip and determines whether a document is to be output based on task permission held by a user associated with the retrieved RFID chip.
