Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for addressing power outages in computer systems fail to adequately reduce power consumption during backup processing, necessitating a more efficient approach to manage power supply disruptions.
Innovation Solution
An arithmetic logic apparatus with a primary and secondary system device, a power supply port, and a battery, where power is detected, switched to battery supply, and the secondary system is ended to reduce consumption, with data backup performed using the primary system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power is supplied to both primary and secondary system devices during power outage, then data backup can be performed, but power consumption increases
Solution Approach 1:
The system is divided into primary system device and secondary system device, with power supply controlled separately for each. During power outage, only the primary system device receives power from the battery, while the secondary system device receives no power, thereby reducing overall power consumption while ensuring data backup functionality.
2Productivity
If secondary system device continues operation during power outage, then processing can continue, but battery power depletes faster
Solution Approach 1:
The secondary system device is extracted from the active power supply during power outage conditions. By removing it from the powered configuration and placing it in a non-powered state, the system reduces battery power depletion while the primary system device continues to perform essential data backup functions.
3Adaptability or versatility
If all system devices remain powered during power outage, then system functionality is maintained, but battery capacity is consumed rapidly
Solution Approach 1:
Different power supply states are applied to different system devices based on their functional requirements during power outage. The primary system device maintains powered status to ensure data backup capability, while the secondary system device is switched to non-powered state, creating localized quality differences in power consumption across system components.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method effectively reduces power consumption during backup processing after a power outage by halting unnecessary power supply to the secondary system, optimizing battery usage and ensuring data preservation.
Implementation Method 1
a battery (33), a power supply control part (2804) that supplies power from the battery (33) to the arithmetic logic part (2) when disruption of power is detected
