Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In production lines with multiple devices using external power, it is challenging for operators to accurately determine when to turn off and restart devices during standby periods, leading to inefficient power usage and increased operational effort.
Innovation Solution
A power management system with automatic on/off circuits that synchronize power operations based on the state of other devices, allowing for automated power management and preventing unintended power activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the power of each device is turned on and off by an operator performing manual operations, then the operator can control power consumption, but the operator's workload increases and it becomes difficult to accurately determine restart timing
Solution Approach 1:
The system enables automatic power management where the power management means autonomously determines standby periods and restart timing based on production schedules, eliminating the need for manual operator intervention. The device A's power is automatically controlled according to its operation state and the states of other devices, allowing the system to self-regulate power consumption without increasing operator workload.
Solution Approach 2:
The power management means continuously monitors the operation states of multiple devices and uses this feedback information to automatically determine when device A should enter standby mode and when it should restart. This closed-loop control ensures accurate timing decisions based on real-time production line conditions.
2Loss of energy
If the operator determines standby time periods manually, then power saving can be achieved by turning off devices, but the operator may perform operations at later timing which hinders production
Solution Approach 1:
The power management means performs preliminary calculations and determinations of standby periods and restart timing based on production schedules before actual operations occur. By pre-determining the optimal timing for power on/off operations and accounting for device startup times, the system ensures that devices are restarted exactly when needed, preventing any hindrance to production while achieving power savings during confirmed standby periods.
3Extent of automation
If automatic power on and off is implemented based on external signals, then power saving is achieved and operator time is saved, but the operator loses direct control over power operations
Solution Approach 1:
The power management means serves multiple functions: it automatically controls power operations to achieve savings, monitors production schedules, determines standby periods, and coordinates with multiple devices. This multi-functional approach consolidates what would otherwise require separate manual operations into a single automated system that enhances rather than reduces operational capability.

AI summary
A component-mounted-board production line includes a power operation switch configured to be operated by an operator to turn power on and off, and an automatic power on and off circuit section configured to turn the power on and off. There is provided a production management means for, in a case where the multiple devices include a device that stops operating and enters a standby state, inputting a power on and off signal to the automatic power on and off circuit section of the device such that the power to device is turned on and off in accordance with an operation state of another device.
