Solution Overview

Problem

Current aircraft power distribution systems face challenges in efficiently managing and allocating electrical power to meet the varying demands of flight plans across a fleet of aircraft, particularly in determining the optimal distribution of replaceable energy modules based on location and flight requirements.

Innovation Solution

A method and system for an energy management system that receives flight plan databases and inventory information, estimates energy demands, and generates a power source inventory distribution plan to allocate dischargeable energy modules to specific aircraft locations, enabling efficient power allocation and sharing between modules to meet flight demands and reduce replacement needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fleet of aircraft uses replaceable energy modules to meet varying power demands, then power allocation flexibility is improved, but tracking and managing module locations and inventory becomes more complex

Engineering Contradiction:
Improvepower allocation flexibilityVSAvoidinventory tracking complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system continuously tracks the location and status of each energy module through GPS coordinates and status indicators (charged, discharging, depleted). This feedback mechanism provides real-time visibility into module distribution across the fleet, enabling dynamic reallocation decisions while maintaining accurate inventory knowledge despite the complexity of multiple movable units

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

A central controller acts as an intermediary between the distributed energy modules and the fleet operations. The controller receives location data from modules, processes power demand requirements, and coordinates module allocation and redistribution. This intermediary manages the complexity by centralizing the tracking and decision-making logic, allowing flexible power allocation without requiring direct complex interactions between all modules

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If energy modules are distributed across multiple aircraft locations, then power availability is improved, but the number of modules that need replacement increases

Engineering Contradiction:
Improvepower availabilityVSAvoidmodule replacement frequency
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The system proactively identifies when energy modules are depleted or require replacement before they cause operational failures. By continuously monitoring module status and predicting replacement needs based on discharge cycles and capacity degradation, the system schedules replacements in advance, ensuring power availability is maintained while optimizing the timing and number of replacements required

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

When energy modules reach the end of their operational life or become depleted, the system systematically retrieves them from the fleet and replaces them with charged modules. The replaced modules are then sent for recharging or refurbishment, creating a recovery loop that minimizes the total number of modules needed in the fleet while maintaining continuous power availability across all aircraft

Inventive Principle:
Principle #34Discarding and recovering
