Modular Component Holder With Bayonet Locking for Aircraft Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle construction methods require numerous single-piece shaped sheet metal components for securing insulation and components, leading to complexity and inflexibility in assembly and replacement.
Innovation Solution
A modular component holder with a base portion and lockable attachment element, featuring a shell-like base and dome-like attachment, allows for flexible attachment to vehicle structures using bayonet closures without additional fasteners, distributing forces evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerous single-piece shaped sheet metal components are used for securing insulation and components, then the structural integrity and securing capability are improved, but the device complexity and storage requirements increase significantly
Solution Approach 1:
The single-piece shaped sheet metal component is divided into two separate modular components: a base portion that attaches to the vehicle structure and an attachment element that secures the insulation. This segmentation allows each component to be optimized independently while reducing the variety of unique components needed.
Solution Approach 2:
The base portion is designed with a universal mounting interface that can accommodate multiple attachment elements with different functions (insulation securing, cable management, component mounting). This universality eliminates the need for numerous specialized single-piece components.
2Reliability
If additional fasteners and securing means are used for attaching components, then the securing reliability is improved, but the device complexity and assembly time increase
Solution Approach 1:
The attachment element integrates multiple functions into a single component: it provides structural support, insulation securing, and locking functionality through its dome-like shape with integrated locking elements. This merging eliminates the need for separate fasteners, pins, and adhesives.
Solution Approach 2:
The attachment element incorporates self-locking mechanisms with the base portion through complementary retention and locking elements. The design enables automatic engagement and locking without requiring additional securing means or complex assembly procedures.
3Ease of operation
If extensive insulation mats are secured in a point-like manner rather than extensively, then the assembly flexibility and replacement ease are improved, but the insulation effectiveness may be compromised
Solution Approach 1:
The insulation mat is divided into multiple sections, each secured by separate attachment elements at specific locations. This segmentation allows for flexible assembly and replacement while maintaining effective insulation coverage through strategically positioned securing points.

AI summary
A component holder, in particular for aircraft, for indirectly securing components to the fuselage or body shell. The component holder has a base portion and an attachment element which is lockable to the base portion and has a component receiving member arranged thereon. The base portion has a circular shell form, and the upper edge has retention and locking elements. The lockable attachment element has a s dome-like basic structure, and the lower edge region has retention and locking elements which complement those of the base portion and are lockable therewith. The component receiving member is formed integrally on the attachment element and arranged at a dome zenith on the outer side. The dome is formed from at least three frames which are angularly offset on the circumference. The frames extend from the dome lower edge region to the base location of the component receiving member at the dome zenith.
