Operation Display Apparatus Power Saving Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In composite operation display apparatuses for multiple independent apparatuses like MFPs and servers, operation information transmission to devices in power saving mode causes unnecessary restoration to normal operating mode, wasting power-saving features.
Innovation Solution
The operation display apparatus selectively transmits operation information, prohibiting transmission to devices in power saving mode when detected, using a processor to manage display data from multiple apparatuses and control input-output interfaces to prevent unnecessary mode restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the composite operation display apparatus transmits operation information to all connected apparatuses, then all apparatuses can respond to user operations, but apparatuses in power saving mode will be unnecessarily restored to normal mode, wasting energy
Solution Approach 1:
The patent applies local quality by differentiating the treatment of operation information transmission based on the individual power state of each connected apparatus. Instead of uniformly transmitting to all apparatuses, the system selectively transmits operation information only to apparatuses currently in normal operating mode, while excluding those in power saving mode. This localized approach to information transmission resolves the contradiction by maintaining operational responsiveness for active devices without triggering unnecessary power state changes in dormant devices.
2Use of energy by stationary object
If the composite operation display apparatus enters power saving mode after inactivity, then power consumption is reduced, but operation information transmission to apparatuses in power saving mode causes them to restore to normal mode, eliminating the power saving benefit
Solution Approach 1:
The patent implements feedback by continuously monitoring the power state of each connected apparatus and using this information to control operation information transmission. The system receives power state information from each apparatus, determines whether each apparatus is in normal mode or power saving mode, and accordingly decides whether to transmit operation information to each apparatus. This feedback mechanism ensures that power saving mode is maintained reliably by preventing transmission-induced mode transitions, thus resolving the contradiction between energy efficiency and mode stability.

AI summary
An operation display apparatus for shared use between a first and a second apparatus each being capable of operating independently, the operation display apparatus including a display, a manipulation device, and a processor, wherein the processor performs: allowing the display to selectively show either of display data received from the first apparatus through a first display interface and display data received from the second apparatus through a second display interface; transmitting operation information of an operation on the manipulation device to the first apparatus through a first input-output interface and to the second apparatus through a second input-output interface; detecting through the first or second display interface whether at least either one of the first and second apparatus enters power saving mode; and prohibiting the transmission of operation information to the first or second apparatus when at least either one of the first and second apparatus enters power saving mode.
