Aircraft Coat Rod Bracket for Quick Secure Cabin Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for attaching and detaching coat rods and cargo nets in aircraft require significant time and effort, protruding hardware poses a risk to cabin occupants, and there is a need for a quick and secure installation method that optimizes limited aircraft space.
Innovation Solution
A bracket with a cross-member embedded in the aircraft cabin wall allows for easy attachment of a rod with an integral hook, using telescoping tubular components and engagement elements that distribute weight evenly and secure the rod without exposed hardware, enabling quick installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hardware with protruding bezels and mounting plates is used, then secure attachment is achieved, but installation time increases and safety risks arise from exposed hardware
Solution Approach 1:
The system divides the attachment mechanism into separate functional components: a permanent embedded bracket with cross-member in the wall panel, and a removable rod assembly with integral hook. This segmentation allows the bracket to remain fixed and secure while the rod assembly can be quickly installed and removed without exposing hardware protrusions.
Solution Approach 2:
The rod assembly with integral hook nests onto the embedded bracket cross-member, with the hook engaging the cross-member from the front side of the panel. This nesting arrangement eliminates the need for protruding mounting hardware while maintaining secure attachment, as the rod is held by the embedded cross-member rather than exposed fasteners.
2Reliability
If traditional protruding hardware is used, then secure attachment is achieved, but safety risks increase due to exposed hardware that could impact occupants
Solution Approach 1:
The invention extracts the protruding hardware (bezel and mounting plate) from the attachment system, leaving only the essential embedded cross-member in the wall panel. The rod assembly with integral hook provides the necessary attachment function without requiring any exposed hardware that could pose a safety risk to cabin occupants.
Solution Approach 2:
The rod assembly nests onto the embedded bracket, with all attachment interfaces occurring behind or flush with the panel surface. The integral hook engages the cross-member without requiring exposed fasteners, eliminating harmful protruding elements while maintaining secure attachment.
3Productivity
If quick attachment is implemented, then installation speed increases, but attachment security may be compromised
Solution Approach 1:
The bracket with cross-member is pre-installed and embedded in the wall panel during aircraft assembly, creating a permanent secure anchor point. This preliminary action allows the rod assembly to be quickly attached later by simply engaging the integral hook with the pre-positioned cross-member, maintaining both speed and security.
Solution Approach 2:
The integral hook is designed with a curved geometry that complements the cross-member shape, allowing for smooth engagement and secure attachment. The curved hook wraps around or engages the cross-member in a manner that distributes load effectively, providing secure attachment through a simple quick-attach motion.
