Aircraft Cabin Panel Holding Device with Elastic Pre-positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for cabin side paneling parts in aircraft fail to maintain components in a nominal position during installation, leading to ineffective shock absorption and rattling noises due to blocked damping elements and lack of adjustability.
Innovation Solution
A holding device comprising a hook and a ring eyelet with an elastically resilient element allows for pre-positioning of components in a nominal position, ensuring damping elements are not blocked and facilitating easier installation and decoupling, featuring a coil spring or deformable filler for adjustable stiffness and oscillation-damping materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If components are fastened directly to the support structure without pre-positioning, then installation is simpler, but the component cannot be held in the nominal position and damping elements become blocked
Solution Approach 1:
The holding device performs preliminary positioning of the component in the nominal position before final fastening. The elastically resilient element supports the hook to maintain the component at the correct height, ensuring damping elements are not blocked during the installation process.
Solution Approach 2:
The holding device acts as an intermediary between the component and the support structure. It temporarily holds the component in the correct position using the elastically resilient element, allowing proper alignment before permanent fastening occurs.
2Productivity
If components are fastened at the lower position only, then installation is faster, but adjustability is lost and rattling noises occur
Solution Approach 1:
The holding device enables preliminary centering of the component in the nominal position before final fastening. This preliminary action ensures both fastening points (lower and middle) are properly aligned, maintaining adjustability while preserving installation speed.
Solution Approach 2:
The elastically resilient element provides adjustable support by changing its elastic properties. This allows the holding device to adapt to different component weights and sizes while maintaining the nominal position, enabling both quick installation and proper adjustability.
3Ease of operation
If damping elements are mounted in blocked positions, then installation is simpler, but shock absorption becomes ineffective and rattling noises occur
Solution Approach 1:
The holding device performs preliminary positioning to ensure damping elements are correctly positioned before final fastening. By holding the component in the nominal position, it prevents damping elements from being mounted in blocked positions, eliminating rattling noises while maintaining installation simplicity.
Solution Approach 2:
The elastically resilient element automatically adjusts to maintain the correct position of the component, ensuring damping elements are properly positioned without requiring additional adjustment steps. This self-adjusting mechanism prevents rattling noises while keeping the installation process simple.
