Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The pre-set bolt holes on aircraft consoles limit the precise placement and mounting flexibility of avionics equipment, which can hinder optimal installation and performance.
Innovation Solution
A mounting rail system with two threaded faces and a mounting bracket secured via fasteners, allowing for an interference fit and adjustable placement, along with spacers for aesthetic and grounding improvements, provides maximum flexibility and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-set bolt holes are used on the console, then the mounting process is simplified, but the placement flexibility and precision of avionics equipment is limited
Solution Approach 1:
The mounting rail serves multiple functions: it provides a continuous threaded engagement surface for secure mounting, acts as a positioning reference for precise placement, and enables adjustable positioning along its length. This universal component replaces both the pre-set bolt holes and separate positioning fixtures, achieving both ease of operation and adaptability.
2Device complexity
If pre-set bolt holes are used on the console, then the structure is simplified, but the mounting precision is reduced
Solution Approach 1:
The mounting rail acts as an intermediary between the console and the avionics equipment. It features a slot that receives a positioning pin from the equipment, establishing precise horizontal alignment, while its threaded faces provide secure vertical attachment. This intermediary component achieves high mounting precision without significantly increasing overall structural complexity.
3Adaptability or versatility
If a mounting rail system with threaded faces is used, then the adaptability and precision are improved, but the device complexity increases
Solution Approach 1:
The mounting rail combines multiple functions into a single integrated component: the slot provides horizontal positioning, the threaded faces provide vertical attachment, and the overall structure serves as both a mounting surface and a positioning reference. This merging of functions achieves high adaptability and precision while minimizing the number of separate components, thus reducing overall system complexity.

AI summary
A mounting rail system for a console of an aircraft includes a pair of mounting rails. The first mounting rail is secured to the console and includes a first track with a pair of threaded faces that are configured to receive a first fastener. The second mounting rail is secured to the console opposite the first mounting rail and includes a second track with a pair of threaded faces that are configured to receive a second fastener. The mounting rail system includes a first mounting bracket configured to be secured to the first mounting rail via the first fastener and a second mounting bracket configured to be secured to the second mounting rail via the second fastener.
