Aircraft Window Mounting Frame With Snap-Click Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft window installations require multiple parts made of different materials, involve complex processes like drilling and eye bolt wet installation, and are prone to corrosion, necessitating high effort and tool usage.
Innovation Solution
A window mounting structure with a single integral part that uses a form-fitting snap and click mechanism, incorporating a mounting support interface and frame with a locking mechanism, allowing easy installation and corrosion resistance, and capable of withstanding pressure differentials without drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional window installation methods are used (drilling, eye bolt wet installation, hybrid bonding and bolting), then the window can be securely mounted to the fuselage, but the installation process requires high effort, multiple tools, and complex procedures
Solution Approach 1:
The mounting frame integrates multiple functions into a single component: the engaging portion combines mechanical engagement and sealing functions, the locking portion integrates locking and sealing features, and the engaging section unifies mounting and retention functions. This eliminates the need for separate drilling, bonding, and bolting operations while maintaining secure mounting.
Solution Approach 2:
The mounting frame is designed to be self-installing through the snap-and-click mechanism where the engaging portion automatically engages with the mounting support interface and the locking portion secures itself without requiring external fastening operations. The window assembly mounts itself through the integrated design.
2Reliability
If traditional window installation methods are used (drilling, eye bolt wet installation), then the window can be mounted to the fuselage, but the process requires drilling operations that compromise the fuselage structure and increase installation complexity
Solution Approach 1:
The invention extracts the drilling operation entirely from the mounting process. Instead of drilling holes in the fuselage rim portion, the mounting frame uses a drilling-free snap-and-click mechanism where the engaging portion interfaces with the exterior surface of the rim portion, eliminating the need for hole creation and reducing fuselage structure compromise.
Solution Approach 2:
The mounting frame is segmented into distinct functional portions: the engaging portion for mechanical attachment, the locking portion for security, and the engaging section for retention. This segmentation allows each portion to perform its specific function independently while simplifying the overall installation process by eliminating complex integrated operations like drilling and bonding.
3Reliability
If traditional window installation methods are used (eye bolt wet installation, hybrid bonding and bolting), then the window can be securely fastened, but the installation requires multiple materials and parts that increase weight and corrosion risk
Solution Approach 1:
The mounting frame merges multiple fastening functions into a single integrated component. The engaging portion, locking portion, and engaging section work together as one unified structure, eliminating the need for separate eye bolts, bonding materials, and fasteners. This reduces the total weight of the mounting structure while maintaining secure fastening through the combined mechanical action of all portions.
4Reliability
If traditional window installation methods are used (drilling, wet installation, bonding), then the window can be mounted to the fuselage, but the process requires multiple tools and high installation effort
Solution Approach 1:
The mounting frame is designed to be self-installing through the snap-and-click mechanism. The engaging portion automatically engages with the mounting support interface when the mounting frame is positioned, and the locking portion secures itself without requiring external fastening operations. This eliminates the time-consuming steps of drilling, bonding, and bolting, reducing installation time significantly while maintaining secure mounting.
Solution Approach 2:
The invention skips the time-consuming traditional fastening operations entirely. Instead of performing sequential operations like drilling holes, inserting eye bolts, applying bonding materials, and tightening fasteners, the snap-and-click mechanism allows the mounting frame to be quickly attached in a single motion, rushing through the installation process while ensuring secure mounting through the integrated locking mechanism.
