Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current business continuity plan (BCP) control methods for managing power supply from private generators during failures lack optimization and efficiency in power usage.
Innovation Solution
A load control apparatus and system that includes a memory for storing prioritized control patterns and a selector to operate loads based on these patterns, ensuring power usage aligns with the generator's capacity, allowing for efficient allocation and usage of generated power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If BCP control supplies power to multiple loads during power failure, then business continuity is maintained, but power consumption may exceed generator capacity
Solution Approach 1:
The patent segments loads into multiple priority groups (first priority, second priority, third priority, etc.) and controls them hierarchically. The controller selectively supplies power to loads based on priority levels, ensuring that critical loads receive power first while less critical loads are suppressed when power is limited, thus preventing total power consumption from exceeding generator capacity.
Solution Approach 2:
The patent changes the operational parameters of loads by adjusting their power supply status based on priority levels and generator capacity. The controller dynamically modifies which loads are active and which are suppressed, optimizing power distribution to match available generator capacity while maintaining business continuity for critical operations.
2Productivity
If all loads are operated simultaneously, then business activities can proceed, but efficient power usage is compromised
Solution Approach 1:
The patent implements dynamic load control where the operational status of each load is not fixed but changes based on current generator capacity and priority requirements. The controller continuously adjusts which loads are active, allowing the system to adapt to varying power availability and maintain optimal power efficiency while ensuring critical business activities continue.
3Loss of energy
If priority-based load control is implemented, then power usage efficiency improves, but control system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-classifying loads into priority groups before power failure occurs. Each load is assigned a priority level in advance, so that when power failure happens, the controller can immediately implement priority-based control without complex real-time decision-making, thereby achieving power efficiency with relatively simple control logic.

AI summary
A load control apparatus and a load control system capable of more efficiently using power generated from a private power generator, in which a load control apparatus includes a memory, a selector, and a load controller. The memory is configured to store a plurality of patterns having a plurality of control operations that are prioritized for a plurality of loads operated by consuming electric power. The selector is configured to select one of the patterns stored in the memory. The load controller is configured to operate the loads in order of priority on the basis of the control operation of the selected pattern while a total sum of power consumed by the loads does not exceed a target power value representing a value based on power suppliable by the electric generator.
