Solution Overview

Problem

Aircraft sidewall panel seams are often poorly aligned, difficult to install, and allow noise and cold air to pass through, compromising passenger comfort and insulation.

Innovation Solution

A panel assembly with a pivot mechanism and magnetic latch system that includes a first and second bracket assembly with specific throat and pivot opening geometries, allowing for easy installation and secure, overlapping fit, and a magnetic release mechanism for quick uninstallation, along with a seal member for enhanced thermal and acoustic insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional mounting assemblies are used for aircraft sidewall panels, then the panels can be installed, but the seams become poorly aligned and difficult to install/uninstall while allowing noise and cold air to pass through

Engineering Contradiction:
Improveease of installationVSAvoidseam alignment quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The mounting assembly is divided into separate bracket assemblies that can be independently positioned and adjusted on each panel. Each bracket assembly includes a bracket and pivot member that can be separately installed and adjusted, allowing precise alignment of panel seams while maintaining ease of installation through modular components

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket assemblies are pre-configured with pivot members and mounting features that enable preliminary positioning and alignment before final panel installation. This preliminary setup ensures proper seam alignment is achieved during installation rather than requiring post-installation adjustment

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If traditional mounting assemblies are used, then panels can be installed, but they allow noise and cold air to pass directly to passengers

Engineering Contradiction:
Improveinstallation simplicityVSAvoidnoise and cold air penetration
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The mounting assembly integrates multiple functions into a single bracket structure: mechanical support, seam alignment, and sealing. The bracket assembly combines the mounting bracket, pivot member, and seal positioning features into one integrated component that simultaneously addresses installation ease and prevents noise and cold air penetration

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bracket assembly acts as an intermediary element between the panel and the aircraft structure, providing a sealed interface that prevents noise and cold air penetration while facilitating easy installation through its pivot mechanism and mounting features

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If panels are designed for secure installation, then they maintain alignment and sealing, but they become difficult to uninstall and maintain

Engineering Contradiction:
Improvepanel alignment stabilityVSAvoiduninstallation difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The pivot member enables dynamic movement of the panel during installation and maintenance, allowing the panel to pivot into place for easy installation and to pivot back for easy removal. During normal operation, the panel remains securely positioned, providing stability while maintaining ease of uninstallation through the reversible pivot mechanism

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bracket assembly is designed to be easily removed and reused for panel maintenance and replacement. The modular bracket and pivot member components can be detached, recovered, and reused rather than discarded, facilitating easy panel maintenance while maintaining secure installation during operation

Inventive Principle:
Principle #34Discarding and recovering
