Solution Overview
Problem
In computer systems where CPU devices and peripheral devices are located in separate casings and have individual power supplies, there is a high power consumption and a risk of incomplete system configurations due to inconsistent power supply to all devices, leading to operational inefficiencies and potential system failures.
Innovation Solution
A connection device and power supply control method that manages power distribution across the network, ensuring that CPU devices and peripheral devices are only powered when necessary, using a logic group structure and interconnection control to maintain a complete system configuration by linking power status changes across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If respective power supplies are disposed for CPU devices and peripheral devices located at remote locations, then system availability is ensured, but power consumption increases
Solution Approach 1:
The patent merges the power supply control of CPU devices and peripheral devices by establishing logic groups that link their power status. When devices are in the same logic group, their power states are coordinated so that peripheral devices are powered only when their associated CPU devices are operating, eliminating unnecessary power consumption while maintaining system availability.
Solution Approach 2:
The patent implements dynamic power supply control where the power state of peripheral devices automatically adjusts based on the operational status of CPU devices. The system dynamically links power status changes within logic groups, enabling peripheral devices to be powered down when not needed and powered up when required, thus optimizing power consumption while ensuring system reliability.
2Use of energy by moving object
If power is supplied to CPU devices but not to peripheral devices, then power consumption is reduced, but system configuration becomes incomplete
Solution Approach 1:
The patent employs feedback mechanisms where the system continuously monitors the operational status of CPU devices and automatically adjusts the power supply to peripheral devices accordingly. When a CPU device is detected to be operating, the system feedback-triggered power supply to its associated peripheral devices, ensuring complete system configuration. When CPU devices are idle, power is reduced, optimizing energy consumption.
3Reliability
If all CPU devices and peripheral devices are supplied with power from individual power supplies, then system availability is maintained, but energy efficiency decreases
Solution Approach 1:
The patent segments the power supply control into logic groups that associate specific CPU devices with their required peripheral devices. This segmentation allows independent power management for each logic group, enabling power to be supplied only to the necessary devices within each group rather than all devices system-wide, thus improving energy efficiency while maintaining system availability.

AI summary
A host monitoring unit in a host connection device (301) detects a change in a connection status between a host device (101) and the host connection device (301) based on a change in power status of the host device (101), and notifies a host connection controller. The host connection controller notifies an I/O connection controller in an I/O connection device (401) connected with an I/O device (201) having a power linking permitted of the change in the connection status, and sets or cancels an interconnection. After the completion of the setting or cancellation of the interconnection, the I/O connection controller notifies an I/O power supply controller of the change in the connection status, and the I/O power supply controller controls an I/O power supply (20).
