Solution Overview

Problem

The existing electrical connector systems for aircraft interiors are time-consuming to assemble, require external tools, and can result in lost parts and damage to the panel coating due to the need for screws, washers, and nuts, necessitating multiple personnel for proper assembly.

Innovation Solution

The electrical connector system employs a push-pull or snap-fit connection mechanism between the connector attachment means and the mating second connector attachment means, eliminating the need for tools and loose parts, allowing for quicker assembly with visual markings for verification and mechanical coding for alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional screw and nut attachment method is used, then reliable mechanical connection is achieved, but assembly time increases and multiple personnel are required

Engineering Contradiction:
Improvemechanical connection reliabilityVSAvoidassembly speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent extracts and eliminates the screw and nut components from the attachment system, replacing them with a push-pull connector mechanism that achieves reliable mechanical connection without traditional fastening elements, thereby speeding up assembly while maintaining connection reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The push-pull connector is designed to be self-assembling through a simple push motion that automatically engages locking features, eliminating the need for manual screwing operations and external tool assistance, thus improving assembly speed while ensuring reliable connection

Inventive Principle:
Principle #25Self-service

2Reliability

If traditional screw and nut attachment method is used, then mechanical connection is established, but assembly process becomes complex requiring external tools

Engineering Contradiction:
Improvemechanical connectionVSAvoidassembly process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes external tools and loose fastening components from the assembly process, integrating all necessary connection features into the push-pull connector itself, which simplifies the assembly process while maintaining reliable mechanical connection

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The connector body and attachment means are merged into a single integrated push-pull mechanism with built-in locking features, eliminating the need for separate screws, nuts, and tools, thus reducing assembly complexity while ensuring reliable connection

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If traditional screw and nut attachment method is used, then connection is secured, but risk of losing loose parts increases

Engineering Contradiction:
Improveconnection securityVSAvoidloss of loose parts
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent combines all connection components into the integrated push-pull connector body, eliminating separate loose parts like screws and nuts that could be lost, while maintaining secure connection through built-in locking mechanisms

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts and eliminates loose fastening components from the system, replacing them with an integrated connector design where all necessary elements are permanently attached, thus preventing loss of parts while ensuring connection security

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If traditional screw and nut attachment method is used, then mechanical fastening is achieved, but damage to panel coating can occur

Engineering Contradiction:
Improvemechanical fasteningVSAvoidpanel coating damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes the screw and nut fastening elements that cause coating damage, replacing them with a push-pull connector that attaches through a recess without requiring threading into the panel surface, thus maintaining mechanical fastening while preventing coating damage

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a recess or mounting hole as an intermediary structure that allows the push-pull connector to attach without direct contact between fastening elements and the panel coating, thus protecting the coating while achieving reliable mechanical fastening

Inventive Principle:
Principle #24Intermediary (Mediator)
