Aircraft Emergency Kit Storage Assembly With Fine Rail Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices for emergency equipment in aircraft are complex to assemble, requiring fitters to reach into the housing to fasten the device, which complicates integration and alignment with aircraft interiors.
Innovation Solution
A storage device with a two-part structure, comprising a pre-assembly assembly and a cover section, where the pre-assembly is fixed first, allowing the cover section to be placed subsequently, and featuring a rail device with a fine adjustment mechanism for precise positioning, including a sliding strip section and locking device for precise alignment with aircraft fastening rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the storage device is assembled as a single integrated unit, then the structural integrity is improved, but the assembly complexity increases and requires fitters to reach into the housing for fastening
Solution Approach 1:
The storage device is divided into two main segments: a pre-assembly assembly (housing with rail device) and a cover section. This segmentation allows the pre-assembly to be fixed to the aircraft interior first, then the cover section is attached separately, eliminating the need for fitters to reach inside the housing during initial installation while maintaining structural integrity through the interlocking design of the segments
2Manufacturing precision
If the storage device requires precise alignment with aircraft fastening rails, then the integration accuracy is improved, but the assembly time increases
Solution Approach 1:
The pre-assembly assembly is prepared in advance with the rail device and fastening mechanisms pre-positioned and pre-aligned. This preliminary action allows the entire pre-assembly unit to be installed as a single module that can be quickly attached to the aircraft's fastening rails without requiring time-consuming on-site alignment adjustments, thus maintaining high precision while reducing assembly time
Solution Approach 2:
The fastening mechanism includes a sliding strip section that can be adjusted dynamically during installation to accommodate minor variations in rail positioning. This dynamic adjustment capability allows for precise alignment to be achieved quickly through simple sliding movements rather than complex adjustment procedures, balancing alignment precision with assembly efficiency
3Ease of operation
If the drawer is made fully movable on the rail device, then the accessibility of emergency equipment is improved, but the risk of accidental displacement increases
Solution Approach 1:
The drawer is designed with periodic locking and unlocking positions along the rail device. During normal operation, the drawer can be moved freely to access emergency equipment. When not in use, the drawer automatically engages with locking positions at regular intervals, preventing accidental displacement while maintaining ease of access when needed
