Replaceable Decorative Seat Belt Buckle Cover for Aircraft Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat belt buckles on aircraft are considered structural components, necessitating costly and time-consuming repairs or replacements when damaged, and require additional inventory for replacement, which is not addressed by existing non-structural solutions.
Innovation Solution
A non-structural seat belt buckle cover comprising a top and bottom cover, forming a clamshell enclosure over the buckle, allowing easy access to the release mechanism while protecting the buckle from damage, and secured with mechanical fasteners or adhesives, avoiding regulatory re-certification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a non-structural buckle cover is used to protect the seat belt buckle, then repair costs and inventory needs are reduced, but the structural integrity and reliability of the seat belt system may be compromised
Solution Approach 1:
The invention divides the protective cover into separate top and bottom covers that can be independently manufactured and assembled. This segmentation allows the non-structural covers to be produced separately from the structural buckle, reducing overall manufacturing complexity and cost while maintaining protective functionality.
Solution Approach 2:
The top and bottom covers act as intermediary protective elements between external damage sources and the structural seat belt buckle. These non-structural covers absorb impact and protect the buckle without requiring the buckle itself to be structural, thereby reducing repair costs while maintaining system reliability.
2Object-affected harmful factors
If the buckle is enclosed in a cover, then the buckle is protected from damage, but access to the release mechanism becomes difficult
Solution Approach 1:
The protective cover is divided into top and bottom sections with openings that allow access to the release mechanism. This segmented design provides damage protection while maintaining operational accessibility without requiring the user to remove the entire cover.
Solution Approach 2:
The cover design incorporates localized openings in specific positions that provide access to the release mechanism while maintaining protective coverage in other areas. This local modification allows operational access without compromising overall protective functionality.
3Reliability
If a structural buckle is used to ensure safety, then reliability is improved, but repair costs and inventory requirements increase
Solution Approach 1:
The system separates structural components (buckle, tongue, retractor) from non-structural protective components (top and bottom covers). This segmentation allows the structural buckle to maintain safety reliability while the non-structural covers can be manufactured more economically and replaced independently.
Solution Approach 2:
The top and bottom covers are designed as inexpensive, replaceable protective elements that can be manufactured at lower cost than structural buckles. When damaged, only the covers need replacement rather than the entire structural buckle assembly, reducing manufacturing costs and inventory requirements.
