Selective Standby Control for Multi-Function Device Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital multi-function devices waste power and resources by placing all input/output devices in standby mode regardless of their necessity, leading to unnecessary power consumption and resource usage when switching between services.
Innovation Solution
A service providing system that selectively places input/output devices into standby mode only when necessary, using a controller to determine the optimal time based on device preparation times and user demands, thereby preventing wastage of power and resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all input/output devices are placed in standby state when switching between services, then devices are ready to be driven quickly, but power and resources are wasted unnecessarily
Solution Approach 1:
The patent applies local quality by differentiating the standby state of each input/output device based on its specific requirements. Instead of placing all devices in standby uniformly, the system determines individually which devices need to be in standby state based on the service being provided, thus avoiding unnecessary power consumption while maintaining readiness for required devices
Solution Approach 2:
The system changes the parameter of device state (standby or not) based on service type and device preparation time. By dynamically adjusting which devices enter standby state according to service requirements and preparation time characteristics, the system optimizes the balance between device readiness speed and power consumption
2Productivity
If all input/output devices are placed in standby state, then service switching is faster, but resource usage increases
Solution Approach 1:
The patent applies local quality by differentiating the standby state of each input/output device based on its specific requirements. Instead of placing all devices in standby uniformly, the system determines individually which devices need to be in standby state based on the service being provided, thus avoiding unnecessary power consumption while maintaining readiness for required devices
Solution Approach 2:
The system performs partial action by placing only the necessary subset of devices in standby state rather than all devices. This partial standby approach maintains sufficient service switching efficiency while reducing resource consumption by avoiding unnecessary standby states for devices not required for the current service
3Reliability
If devices are placed in standby state immediately, then device availability is improved, but preparation time is wasted
Solution Approach 1:
The patent applies preliminary action by placing devices in standby state only when they are actually needed for the service, rather than immediately for all devices. The system calculates the optimal time to place each device in standby based on when it will be required, avoiding unnecessary early activation while ensuring devices are ready when needed
Solution Approach 2:
The system dynamically determines the timing of device standby state transitions based on service requirements and device preparation characteristics. Rather than using a fixed immediate standby approach, the system adaptively adjusts when each device enters standby state, optimizing both device availability and avoiding unnecessary preparation time

AI summary
A service providing system includes input/output devices, a service providing device configured to provide services by driving the input/output devices, and a preparation device, in response to receipt of a provision command for a service, configured to selectively place the input/output devices, for providing the service, which are in a non-standby state, into a standby state. In a multi-function device system including input/output devices, a method of providing a service includes receiving a provision command for a service, and selectively placing the input/output devices for providing the service into a standby state in response to the provision command.
