Solution Overview

Problem

Current electrical network architectures for confined environments like aircraft are inefficient due to single-path energy transport, leading to mass oversizing, complex configuration management, and inability to dynamically balance energy sources with loads, causing safety issues and certification challenges when adding new loads or managing peak currents.

Innovation Solution

A new electrical network architecture with independent relays and dynamic balancing capabilities allows simultaneous connection of loads to multiple conductors and sources, enabling flexible load distribution and protection against overcurrents, simplifying integration and reducing wiring mass.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conductor sections are increased from load to source to accommodate peak currents, then the reliability is improved, but the weight of the wiring increases

Engineering Contradiction:
ImprovereliabilityVSAvoidweight of the wiring
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent implements dynamic current sharing among multiple conductors connecting loads to power sources. Conductors that would normally be overloaded during peak consumption can temporarily share their capacity with other conductors through active control, allowing the use of lighter individual conductor sections while maintaining overall system reliability during peak currents.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a single path is used for energy transport to each load, then the device complexity is reduced, but the reliability deteriorates because a break in one conductor prevents normal operation

Engineering Contradiction:
Improvedevice complexityVSAvoidreliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent makes conductors multi-functional by enabling each conductor to serve multiple purposes: normally supplying its designated load, but also temporarily sharing capacity with other loads during peak consumption periods. This universal usage allows the system to maintain simple single-path topology while achieving the reliability benefits of redundant paths through active load sharing.

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

3Adaptability or versatility

If multiple optional loads are integrated into the network, then the adaptability is improved, but the difficulty of detecting and measuring increases due to configuration management problems

Engineering Contradiction:
ImproveadaptabilityVSAvoiddifficulty of detecting and measuring
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements self-service through automatic detection and configuration of optional loads. When a new load is connected, the system automatically detects it, determines its power requirements, and configures the appropriate conductors and power sources without manual intervention. This eliminates configuration management problems while maintaining high adaptability for integrating new loads.

Inventive Principle:
Principle #25Self-service
