Solution Overview

Problem

In a facility complex with shared fuel storage, arbitrary use of limited fuel during fuel replenishment stagnation or power outages can lead to unfair distribution of resources among facilities.

Innovation Solution

An energy management system that includes a power management server and a local control apparatus, which allocates the stored fuel amount fairly among facilities based on various allocation methods, such as equal allocation, historical power consumption, rated output power, remaining battery charge, and power generation prediction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If fuel is shared in a common storage tank among multiple facilities, then space efficiency is improved, but fuel distribution fairness deteriorates when replenishment is stagnant

Engineering Contradiction:
Improvestorage tank volume utilizationVSAvoidfuel distribution fairness
Core Design Contradiction:
Volume of stationary objectVSReliability

Solution Approach 1:

The system segments the shared fuel storage into virtual allocated quantities for each facility. The manager divides the total stored fuel amount into facility-specific allocated amounts based on predetermined criteria (power consumption history, rated output power, etc.), ensuring each facility receives a fair share even though they physically share a common storage tank.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements feedback mechanisms where the manager continuously monitors the stored fuel amount and compares it against allocated quantities for each facility. When the stored fuel falls below the allocated amount for a particular facility, the controller prioritizes fuel supply to that facility, ensuring fairness is maintained through continuous monitoring and adjustment.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If fuel is allocated based on arbitrary use during power outages, then operational flexibility is improved, but resource equity deteriorates

Engineering Contradiction:
Improvefuel usage flexibilityVSAvoidfuel distribution equity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The system performs preliminary allocation of fuel quantities to each facility before power outages or fuel shortages occur. The manager calculates and sets allocated fuel amounts based on historical power consumption data and rated output power, so that when emergencies occur, fuel distribution follows pre-determined equitable principles rather than arbitrary decisions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes the allocation parameters dynamically based on facility needs. The manager considers multiple parameters including power consumption history, rated output power, and current operational status to determine fair allocated quantities, adjusting these parameters to ensure equity while maintaining operational flexibility during outages.

Inventive Principle:
Principle #35Parameter changes
