Proximity-Based Automatic Printing Control for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses require user intervention for printing, which can lead to inefficiencies and security risks, especially when mobile terminals are in close proximity, as they lack automated detection and control mechanisms to manage printing data based on user presence and proximity.
Innovation Solution
An image forming apparatus equipped with a detector to sense the proximity of mobile terminals, a controller to manage printing data based on preset conditions, and an output unit that automatically prints data from mobile terminals within a specific range without user operation, ensuring secure and efficient printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic printing is implemented when mobile terminals are near, then productivity is improved, but security risks increase
Solution Approach 1:
The patent applies local quality by implementing different printing modes for different spatial zones. When a mobile terminal is detected within a specific distance range (preset range), the system automatically executes printing. When the terminal is outside this range, user confirmation is required. This creates a localized security policy based on spatial proximity, allowing automatic printing only in the safe zone near the device while maintaining security controls for distant access.
Solution Approach 2:
The system performs preliminary detection of the mobile terminal's distance before initiating printing. The detector unit continuously monitors the distance between the mobile terminal and image forming apparatus in advance, and the controller unit uses this pre-detected information to automatically authorize printing when the terminal is within the preset range, eliminating the need for last-minute user confirmation and improving printing efficiency.
2Reliability
If user intervention is required for printing, then information security is improved, but productivity deteriorates
Solution Approach 1:
The patent implements dynamic printing control where the authentication requirement changes based on real-time distance detection. The system dynamically adjusts between two states: automatic printing mode when the mobile terminal is within the preset range, and confirmation-required mode when outside the range. This dynamic adaptation allows the system to optimize between security and efficiency based on the user's actual proximity to the device.
3Extent of automation
If distance detection is implemented, then automation capability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a detector unit as an intermediary component that bridges the mobile terminal and the controller unit. This detector automatically measures the distance between the terminal and apparatus, providing objective data to the controller for automated decision-making. By using this intermediary sensing mechanism, the system achieves automatic printing control without requiring complex user interfaces or manual authentication systems.
Data Source
AI summary
An image forming apparatus includes a detector, a reception unit, an output unit, and a controller. The detector detects a distance between the image forming apparatus and a mobile terminal apparatus that is located near the image forming apparatus. The reception unit receives printing data from a mobile terminal apparatus. The output unit outputs, when a specific operation is performed by a user, a printing result based on the printing data received by the reception unit. The controller controls, in a case where the printing data received by the reception unit is printing data from a mobile terminal apparatus for which the distance detected by the detector is within a preset range, the output unit to output the printing result without requiring the specific operation by the user.
