Operation Part Power Control for Faster Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing information processing systems, the operation part cannot receive user requests until it is fully started up, leading to a perceived increase in startup time, as it is separated from the body part and operates independently with its own OS.
Innovation Solution
An information processing system where the operation part receives a power control instruction to reboot and enter a sleep state during shutdown, and upon receiving a start-up notification from the body part, it returns from this sleep state quickly, allowing it to become usable sooner.

1Speed
If the operation part is separated from the body part and operates independently with its own OS, then the system can perform rapid copy operations by heating only the fixing part, but the operation part cannot receive user requests until it is fully started up, leading to a perceived increase in startup time
Solution Approach 1:
The operation part is caused to reboot and enter a standby state in advance before the body part is fully shut down. This preliminary action allows the operation part to be ready to receive user requests immediately when the body part restarts, eliminating the perceived startup delay while maintaining the independent operation structure that enables rapid copy operations.
Solution Approach 2:
The operation part transitions dynamically between different power states (standby state during shutdown, active state during operation). By controlling the operation part to maintain a standby state rather than fully shutting down, the system achieves rapid response to user requests while preserving the structural independence that enables efficient fixing part heating for copy operations.
2Loss of energy
If the operation part enters a complete shutdown state, then power consumption is reduced, but the startup time increases as the operation part must fully boot up before receiving user requests
Solution Approach 1:
Instead of allowing the operation part to completely shut down, the system applies partial action by maintaining the operation part in a standby state with minimal operations stopped. This partial shutdown reduces power consumption compared to full operation while avoiding the full startup time penalty, as the operation part can quickly transition from standby to active state.
Solution Approach 2:
The power state parameter of the operation part is changed from complete shutdown to standby state. This parameter change allows the operation part to consume less power than full operation while maintaining readiness to quickly resume full functionality, thereby reducing both power loss during shutdown and startup time.

AI summary
An information processing system includes an operation part that receives an operation performed by a user; and a body part that operates based on a request from the operation part. The operation part includes a power control part that, when receiving a power turning off instruction from the body part, reboots the operation part and causes the operation part to stand by in a power saving state in which some of operations are stopped, and, when receiving a start up notification from the body part, causes the operation part to return from the power saving state.
