Solution Overview
Problem
Current printing devices with near field communication interfaces lack the ability to effectively execute specific functions based on instructions from external devices while also ensuring user authentication, leading to restricted functionality without a unified solution for both wireless communication and authentication operations.
Innovation Solution
A function executing device equipped with a communication unit for near field wireless communication, a specific function unit, storage for function execution restrictions, and a controller that manages user authentication and function execution based on received instructions, allowing for secure and authorized execution of functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the printing device receives printing instructions through near field communication, then wireless printing functionality is enabled, but user authentication and function restriction capabilities are compromised
Solution Approach 1:
The patent combines near field communication interface and user authentication functions into a single integrated system. The controller processes both wireless communication protocols and authentication verification, allowing the printing device to simultaneously support wireless printing and secure user authentication without requiring separate systems.
Solution Approach 2:
The printing device is designed with multi-functional capabilities, where the controller can execute multiple functions including wireless communication reception, user authentication verification, and function restriction enforcement. This universal design allows a single device to handle diverse operations securely.
2Reliability
If user authentication is implemented to restrict function access, then security is improved, but device complexity increases
Solution Approach 1:
The authentication system is merged with the existing controller architecture rather than implemented as a separate complex subsystem. The controller integrates user verification logic and function restriction enforcement into its existing processing framework, reducing overall system complexity while maintaining security.
Solution Approach 2:
The system automatically verifies user authentication and enforces function restrictions without requiring external authentication servers or complex verification procedures. The printing device itself performs user verification and access control, simplifying the authentication infrastructure.
3Adaptability or versatility
If both wireless communication and authentication functions are integrated, then functionality is enhanced, but processing time increases
Solution Approach 1:
The system performs user authentication verification in advance before executing printing functions. By verifying user credentials and determining access permissions prior to processing print jobs, the system avoids time-consuming verification delays during actual printing operations.
Solution Approach 2:
Once user authentication is established, the system maintains continuous access permissions for the authenticated user, allowing multiple printing operations without repeated authentication. This continuity reduces processing time for subsequent printing tasks while maintaining security.

AI summary
A function executing device includes a communication unit configured to perform wireless communication with an external device; a specific function unit configured to execute at least one specific function; a storage configured to store function execution restricting information; and a controller. The controller receives external receiving information, which is information including at least user authentication information. When the received external receiving information includes the specific function instruction information, the controller causes the specific function unit to execute the one of the at least one specific function. When the received external receiving information does not include the specific function instruction information, the controller determines whether an authentication target user is included in the at least one registered user. The controller sets the authentication target user as a current-authenticated user when it is determined that the authentication target user is included in the at least one registered user.
