Multifunction Peripheral Warm-Up Control for Power and Response Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifunction peripherals often fail to quickly activate function units in response to user instructions, leading to unnecessary delays and increased power consumption, as they remain in power save mode until a specific function is explicitly selected, even if another function is intended for immediate use.
Innovation Solution
A multifunction peripheral system that includes a detection unit, a function extraction unit, and a warm-up operation control unit, which identifies the most likely function to be used based on state changes and user permissions, and executes a warm-up operation for the corresponding device, thereby reducing power consumption and response time.

Engineering Contradiction Analysis
1Loss of energy
If the multifunction peripheral stays in power save mode to reduce power consumption, then power consumption is reduced, but the activation time of function units increases
Solution Approach 1:
The system performs preliminary actions by executing warm-up operations for function units that are likely to be used next, based on detected state changes and stored usage patterns. This allows the function units to be prepared in advance while the system remains in power save mode, thus reducing both power consumption and activation time when the user actually needs the function.
2Speed
If the multifunction peripheral activates all function units immediately upon user instruction, then response time is improved, but power consumption increases
Solution Approach 1:
Instead of activating all function units immediately, the system performs preliminary actions only for the specific function unit that is likely to be used, based on detected state changes and stored relationships. This selective warm-up approach improves response time for the needed function while avoiding unnecessary power consumption from activating other function units.
Solution Approach 2:
The system applies different power management strategies to different function units based on their individual usage likelihood. Rather than uniformly activating all function units or keeping all in power save mode, the system locally optimizes by warming up only the specific function unit that matches the detected state change, thus achieving local quality in power management.
3Device complexity
If the multifunction peripheral uses a simple power save mode without predictive warm-up, then device complexity is reduced, but productivity decreases
Solution Approach 1:
The system uses preliminary action by storing pre-defined relationships between state changes and expected functions in advance. When a state change is detected, the system simply retrieves the corresponding function unit from storage and activates it, rather than performing complex real-time analysis. This approach improves productivity through efficient function activation while keeping the control system relatively simple.
Solution Approach 2:
The system implements self-service by automatically detecting state changes and autonomously determining which function unit to activate based on stored relationships. The system serves itself by making intelligent decisions about function activation without requiring complex user input or manual intervention, thus improving productivity while maintaining manageable system complexity.
