Solution Overview

Problem

The existing aircraft wiring systems require extensive planning and manufacturing effort, are cumbersome to adjust when system components are rearranged, and result in weight penalties due to the need for cable harnesses and holders, limiting flexibility and increasing installation time.

Innovation Solution

An adaptable network of lines, preferably glass fibers, is integrated into the aircraft structure, forming a lattice pattern that supports power and data transmission, allowing for pre-installed connection routes with minimal weight increase, enabling flexible reconfiguration of system components without redefining the entire cabling infrastructure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional cable harnesses and holders are used for aircraft wiring, then reliable electrical connections are achieved, but weight increases and installation complexity increases

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidwiring system weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent combines the cable routing function with the aircraft structure itself by embedding conduits and cable pathways directly into structural components like floor beams, side walls, and bulkheads. This integration eliminates the need for separate cable harnesses and holders, reducing overall weight while maintaining reliable electrical connections between system components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The aircraft structural elements serve multiple functions: they provide structural support and simultaneously house the wiring infrastructure. The conduits and cable pathways are built into the structure during manufacturing, allowing the same components to fulfill both mechanical and electrical routing roles, thereby reducing the weight penalty associated with dedicated wiring systems.

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

2Area of stationary object

If cable routing is determined during aircraft configuration, then space requirements are managed, but adaptability to component rearrangement decreases

Engineering Contradiction:
Improvecable space allocationVSAvoidcable routing flexibility
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The wiring infrastructure is divided into modular sections with standardized connection points and access panels located throughout the aircraft structure. This segmentation allows individual cable runs to be accessed, modified, or reconfigured without affecting the entire wiring system, enabling adaptability to component rearrangements while maintaining organized space utilization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a dynamic cable routing system where conduits and pathways are designed to accommodate future modifications. Access panels and connection points are strategically positioned to allow easy reconfiguration of cable routes when system components are rearranged, providing flexibility without requiring complete redefinition of the cabling infrastructure.

Inventive Principle:
Principle #15Dynamics

3Reliability

If cables are spaced away from aircraft structure to prevent chafing, then cable protection is improved, but installation complexity and time increase

Engineering Contradiction:
Improvecable protection from damageVSAvoidinstallation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent integrates cable protection directly into the aircraft structure by embedding conduits and protective pathways within structural components during manufacturing. This approach protects cables from chafing and damage while eliminating the need for separate protective measures and complex installation procedures, thereby improving both cable protection and installation efficiency.

Inventive Principle:
Principle #5Merging (Combining)
