Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing and removing decoration panels in aircraft ceiling assemblies are complex and time-consuming, often requiring the removal of multiple aircraft structures and the use of visible fasteners that detract from aesthetics.
Innovation Solution
A method and system for installing decoration panels in aircraft ceiling assemblies involve removing a generic panel to create an opening, inserting the decoration panel, and coupling it to the ceiling assembly using a plurality of fasteners, including hooks and clamp hooks, which are concealed by a generic panel upon reinstallation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing fasteners are used to install decoration panels, then the panels can be securely fastened to the ceiling assembly, but the fasteners are visible and detract from the aesthetics of the decoration panels
Solution Approach 1:
A valence panel is introduced as an intermediary component that covers the fasteners. The valence panel is installed around the perimeter of the decoration panel, concealing the visible fasteners while maintaining secure attachment. This mediator element resolves the aesthetic conflict by hiding the functional fasteners from view.
Solution Approach 2:
The ceiling assembly is segmented into multiple components: ceiling panels, decoration panels, and valence panels. This segmentation allows the valence panel to be positioned specifically to cover fasteners without interfering with the structural integrity or aesthetic presentation of the decoration panel.
2Ease of manufacture
If the ceiling assembly is removed and disassembled outside the aircraft to install rigid decoration panels, then the panels can be installed, but the process becomes more complex and time consuming
Solution Approach 1:
The decoration panel is designed with flexible properties, allowing it to be bent and manipulated during installation. This flexibility enables the panel to be inserted through the service volume opening in the ceiling assembly without requiring complete removal of the ceiling assembly, significantly reducing installation time and complexity.
Solution Approach 2:
The decoration panel utilizes a flexible shell structure that can deform during insertion and then return to its original shape. This flexible design allows the panel to pass through the limited opening in the ceiling assembly and be properly positioned without requiring the ceiling assembly to be completely disassembled.
3Stability of the object's composition
If rigid decoration panels are used, then the panels provide structural stability, but they cannot fit through the service volume of the ceiling assembly
Solution Approach 1:
The decoration panel transitions from a rigid state during final installation to a flexible state during insertion. The panel is designed to be manipulated into a curved or bent configuration that allows it to pass through the service volume opening, after which it returns to its stable, flat configuration to provide the required structural stability.
Solution Approach 2:
The physical parameters of the decoration panel, specifically its rigidity and flexibility, are dynamically changed during the installation process. The panel is temporarily deformed to reduce its rigidity for insertion, then restored to its original rigid state to provide structural stability once installed.
