Remote Control Terminal Proximity Priority for Access Conflict Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for image forming apparatuses, such as multifunction machines, lack efficient methods to manage user priority and exclusion when multiple terminals attempt to access the device, leading to potential conflicts and unauthorized operations.
Innovation Solution
A remote control terminal apparatus that determines proximity to the image forming apparatus using short-range radio waves and autonomously establishes priority among terminals, broadcasting notifications to prevent conflicts and restrict unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple terminals can access the image forming apparatus simultaneously, then user accessibility and convenience are improved, but access conflicts and operational errors increase
Solution Approach 1:
The system performs preliminary actions by having terminals broadcast their presence and acquisition status before actual access occurs. The terminal apparatus broadcasts a notification when it acquires access rights, allowing other terminals to preemptively adjust their behavior and avoid simultaneous access attempts, thereby preventing conflicts before they happen.
Solution Approach 2:
The system implements feedback mechanisms where terminal apparatuses continuously monitor the broadcast notifications from other terminals. When a terminal detects that another terminal has acquired access rights, it receives feedback information and automatically adjusts its access attempts accordingly, creating a closed-loop system that prevents conflicts through real-time information exchange.
2Reliability
If a complex authentication system is implemented to manage multiple users, then access control reliability is improved, but system complexity increases
Solution Approach 1:
The terminal apparatuses perform self-service by autonomously determining their own access rights based on proximity detection and broadcast notifications. Each terminal independently monitors the broadcast signals and makes its own determination about whether to attempt access, eliminating the need for a complex centralized authentication system while maintaining reliable access control.
Solution Approach 2:
The invention extracts the authentication and access control functions from a complex centralized system and distributes them to individual terminal apparatuses. Each terminal independently handles its own access determination by listening to broadcasts and making local decisions, thereby simplifying the overall system architecture while maintaining reliable access control.
3Reliability
If proximity-based access determination is used, then access conflict prevention is improved, but detection accuracy requirements increase
Solution Approach 1:
The system introduces broadcast notifications as an intermediary mechanism that mediates between distance detection and access determination. Instead of directly using precise distance measurements to control access, the system uses broadcasts transmitted by terminal apparatuses as an intermediary carrier of access status information, thereby reducing the burden on distance detection precision while maintaining reliable access control.

Function Achieved in This Case
Ensures that only the terminal closest to the image forming apparatus can perform remote control operations, preventing conflicts and unauthorized use by notifying other terminals of the established priority, thus enhancing user management and system security.
Implementation Method 1
a notification unit that notifies other terminal apparatuses that the remote control is possible when the remote control is possible

AI summary
Provided is a remote control terminal apparatus including a controller that brings the remote control terminal apparatus into a state in which remote control on a remote control target apparatus is possible when a distance between the remote control terminal apparatus and the remote control target apparatus is less than a threshold value, and a notification unit that notifies other terminal apparatuses that the remote control is possible when the remote control is possible.
