Solution Overview

Problem

Existing aircraft power distribution systems face challenges in efficiently managing power demand for flight plans, particularly in optimizing the allocation of replaceable and dischargeable energy modules across a fleet of aircraft.

Innovation Solution

An energy management system that includes a controller module to receive flight plan databases, inventory databases, and estimate energy demands, determining the availability of dischargeable energy modules at specific locations, and generating a power source inventory distribution plan to allocate these modules effectively for flight plans.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If replaceable energy modules are used in aircraft power distribution systems, then power demand for flight plans can be met, but the complexity of managing and allocating these modules across a fleet increases

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidmodule management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The energy management system continuously monitors the state of dischargeable energy modules across the fleet, tracking their locations, availability, and charge levels. This feedback information is used to dynamically adjust allocation decisions and generate optimized distribution plans that adapt to changing conditions, thereby managing complexity through intelligent control rather than static procedures

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary estimation of energy demands for desired flight plans before actual operations. By predicting power requirements in advance and proactively allocating dischargeable energy modules to appropriate aircraft locations, the system prevents power shortages and reduces the need for last-minute replacements, simplifying on-ground operations

Inventive Principle:
Principle #10Preliminary action

2Productivity

If dischargeable energy modules are allocated across the fleet, then operational efficiency is enhanced, but the challenge of tracking and locating modules at specific positions arises

Engineering Contradiction:
Improveoperational efficiencyVSAvoidmodule location tracking
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The energy management system serves multiple functions simultaneously: it estimates energy demands, tracks module locations, determines availability, generates distribution plans, and monitors fleet-wide power needs. This multi-functional approach consolidates what would otherwise require separate systems into a unified platform, making the tracking and management of dischargeable energy modules across the fleet more efficient and less complex

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The controller module acts as an intermediary between the physical dischargeable energy modules and the fleet operations. It receives data from various sources including flight plan databases and inventory databases, processes this information, and generates actionable distribution plans. This intermediary layer abstracts the complexity of tracking individual modules, presenting a simplified view to operators while maintaining detailed awareness of module locations and status

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If energy demand estimation is performed for flight plans, then power allocation accuracy is improved, but the computational requirements and system complexity increase

Engineering Contradiction:
Improveenergy demand estimation accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system estimates energy demands for at least a subset of desired flight plans rather than attempting to calculate all possible scenarios. This partial action approach focuses computational resources on the most critical or likely flight plans, achieving sufficient accuracy for operational decision-making without the excessive complexity of comprehensive analysis of every possible flight scenario

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The energy management system divides the fleet into manageable subsets and processes flight plans in groups rather than as a single monolithic problem. By segmenting the calculation workload across different aircraft and time periods, the system achieves accurate energy demand estimation for each segment while keeping overall computational complexity at manageable levels through distributed processing

Inventive Principle:
Principle #1Segmentation
