Controller Detects User Presence to Prevent Misuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multifunction office apparatuses, users may mistakenly believe the device is available for use when the logged-in user is not operating the panel, leading to potential misuse due to the apparatus's size and placement of output trays relative to the operation panel.
Innovation Solution
An information processing apparatus with a controller that uses near-field communication and human sensors to detect logged-in users within specific ranges, preventing automatic log-out when they are nearby and notifying approaching users that the apparatus is in use through message transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the apparatus is equipped with finishing function and paper folding function, then the output tray must be positioned distant from the operation panel, but this causes another user to mistakenly believe the apparatus is not in use
Solution Approach 1:
The patent introduces an intermediary notification mechanism (visual display and audio output) that communicates apparatus usage status to approaching users. This mediator resolves the information gap created by the physical separation between operation panel and output tray, allowing users to accurately determine apparatus availability without misinterpreting the absence of personnel at the operation panel.
2Ease of operation
If the logged-in user moves away from the operation panel to collect printed material, then the user can access the output tray, but another user may mistakenly believe the apparatus is available for use
Solution Approach 1:
The patent implements a feedback system that continuously monitors the presence of logged-in users within a predetermined range of the apparatus and communicates this status to approaching users through notification displays and audio outputs. This feedback loop ensures that even when the logged-in user is temporarily away from the operation panel to collect printed material, the apparatus usage status remains clearly communicated, preventing potential misuse by other users.
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
Prevents unauthorized use by ensuring logged-in users are not automatically logged out when near the device and informs approaching users that the apparatus is in use, maintaining convenience for logged-in users and preventing misuse.
Implementation Method 1
a near-field communication device 2 that uses near-field communication to allow data communication between the multifunction apparatus 10 and a portable terminal 34
Implementation Method 2
a human sensor 3 that serves as a detecting unit for detecting a user approaching the multifunction apparatus 10
Data Source
AI summary
An information processing apparatus includes a controller. The controller performs control such that, when a logged-in user is located within a first predetermined range from the apparatus, a second user approaching the apparatus is notified that the apparatus is in use.
