Dynamic Operation Control for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses remain idle or inconvenience users due to automatic operation prohibition at reserved times, even if other users are available to use them, leading to inefficient resource utilization and user dissatisfaction.
Innovation Solution
An image forming apparatus equipped with a near field wireless communication device, terminal detecting unit, and operation restriction unit that dynamically changes operation modes based on user reservations and current usage, allowing other users to access the device when it is not reserved and switching back to prohibition mode when the reserving user arrives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image forming apparatus automatically changes to operation prohibition status at the reserved usage time, then the reserving user can ensure usage availability, but the apparatus remains idle if the reserving user is not present, reducing resource utilization efficiency
Solution Approach 1:
The operation prohibition status is made dynamic rather than static. The system continuously monitors for user presence via terminal detection and automatically adjusts the operation status based on real-time conditions. When a reserving user arrives (detected terminal), the apparatus transitions from prohibition to permission status automatically, allowing flexible adaptation between guaranteed availability and efficient utilization without manual intervention.
2Reliability
If the image forming apparatus prohibits operations during reserved time zones, then reservation reliability is maintained, but other users cannot use the apparatus even when the reserving user is absent, causing user inconvenience
Solution Approach 1:
The system implements feedback through terminal detection to monitor user presence in real-time. Based on this feedback information, the operation permission status is automatically adjusted. When no terminal is detected during a reservation period, the system permits other users to operate the apparatus. When a terminal is detected, the system automatically transitions to prohibition status, ensuring the reserving user can use the apparatus without conflict.
3Reliability
If the apparatus switches to operation prohibition mode at the operation starting time, then the reserving user's usage is protected, but if another user is using the apparatus, their usage is interrupted causing inconvenience and delays
Solution Approach 1:
The system performs preliminary detection of user presence before the operation starting time arrives. By detecting whether the reserving user's terminal is present in advance, the system can prepare the operation status accordingly. This prevents unnecessary interruptions to current users, as the prohibition status is only activated when the reserving user actually arrives, not merely based on time scheduling.

Function Achieved in This Case
Enables efficient use of image forming apparatuses by allowing other users to access the device when reserved times are not utilized, reducing inconvenience and improving resource utilization, while ensuring the reserving user can start using it upon arrival.
Implementation Method 1
a near field wireless communication device (34), a terminal detecting unit configured to detect a mobile terminal device (1) by using the near field wireless communication device (34)

AI summary
In an image forming apparatus, a reservation managing unit receives a reservation request from a mobile terminal device of a user, and registers reservation information. The reservation information indicates (a) a usage time zone specified by the received reservation request and (b) the mobile terminal device. The operation restriction unit changes an operation control mode from an operation permission mode to an operation prohibition mode if (a) the mobile terminal device detected by a terminal detecting unit is a mobile terminal device of a reserving user who reserved as the usage time zone a current or a next time zone and (b) there are no currently using users. The operation permission mode is a status where an operation of an unspecified user can be received, and the operation prohibition mode is a status where a user operation is prohibited until a release operation of the reserving user.
