Aircraft Interior Bracket with Angled Body and Insert Feature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing components in aircraft interiors, such as L and T mortise and tenon bonded joints, are inadequate for providing a strong and versatile connection between panels.
Innovation Solution
A bracket design featuring a main body with a first and second portion forming a specific angle, including fastener and adhesive openings, and an insert feature with a post and alignment protrusion for secure bonding and fastening of panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional L and T mortise and tenon bonded joints are used to secure panels, then the connection strength is improved, but the device complexity and adaptability are reduced
Solution Approach 1:
The bracket is divided into multiple functional segments: a main body portion with first and second portions forming an angle, an insert feature with a post and foot, fastener openings, and adhesive openings. This segmentation allows each part to perform its specific function while maintaining overall connection strength and adaptability.
Solution Approach 2:
The bracket integrates multiple functions into a single component: it provides mechanical fastening through fastener openings, chemical bonding through adhesive openings, alignment through the alignment portion, and structural connection through the angled main body. This multi-functionality replaces multiple traditional joints with one versatile bracket.
2Strength
If traditional bonded joints are used to secure panels, then the connection strength is improved, but the ease of manufacture and installation are reduced
Solution Approach 1:
The bracket is pre-manufactured with all necessary features including fastener openings, adhesive openings, and the insert feature with alignment portion. This preliminary preparation allows for quick installation without requiring complex assembly steps during the installation phase.
Solution Approach 2:
Multiple manufacturing operations are merged into a single bracket component. The fastener openings, adhesive openings, and insert feature are all integrated into one piece that can be manufactured as a single unit, simplifying the manufacturing process compared to assembling multiple separate joint components.
3Strength
If traditional bonded joints are used to secure panels, then the connection strength is improved, but the adjustability for various angles is reduced
Solution Approach 1:
The bracket provides dynamic adaptability through its angled configuration between the first and second portions, allowing it to accommodate different panel angles and orientations. The specific angle between portions can be optimized for different structural requirements while maintaining connection strength.
