Coaxial Attenuator Mounting Bracket for Aircraft Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing amplitude of signals generated by aircraft equipment poses challenges in maintaining coaxial attenuators, as larger devices are harder to fix securely due to insufficient surface area, leading to potential disconnection during flight conditions like turbulence and vibrations, which can disrupt data transmission.
Innovation Solution
A mounting bracket system with a frame, partitions, and fixing devices that securely hold the coaxial attenuator in place, preventing longitudinal, lateral, and vertical movements, and attaching it to a rigid structure using clamps and screw/nut systems, ensuring the attenuator remains firmly fixed despite vibrations and turbulence.

Engineering Contradiction Analysis
1Object-generated harmful factors
If the size of the coaxial attenuator is increased to manage high signal amplitude, then the electromagnetic interference management is improved, but the ease of secure installation deteriorates due to insufficient surface area on equipment
Solution Approach 1:
A mounting bracket is introduced as an intermediary component between the coaxial attenuator and the equipment. The bracket provides additional mounting surfaces and attachment points, enabling secure installation of large attenuators on equipment with limited surface area. The bracket acts as a mediator that resolves the conflict between attenuator size and installation ease.
2Ease of manufacture
If the coaxial attenuator is attached directly to equipment using rivets or simple fasteners, then the ease of installation is improved, but the reliability of attachment deteriorates under flight conditions such as turbulence and vibrations
Solution Approach 1:
The mounting system is segmented into multiple components: a mounting bracket with frame structure, multiple partitions, and multiple fixing devices. This segmentation allows each component to perform a specific function - the bracket provides structural support, partitions create positioning features, and fixing devices provide secure attachment. The segmented design enhances reliability while maintaining ease of installation.
Solution Approach 2:
The mounting system incorporates flexible elements such as elastic bands and adjustable fixing devices that can dynamically adapt to vibrations and turbulence. The elastic bands provide continuous contact pressure that maintains attachment reliability under dynamic flight conditions, while the adjustable nature of the fixing devices allows for easy installation and removal.
3Reliability
If multiple fixing devices and partitions are used to securely attach the attenuator, then the attachment reliability is improved, but the device complexity increases
Solution Approach 1:
Multiple functional elements are merged into a single integrated mounting bracket assembly. The frame, partitions, and fixing device mounting locations are combined into one structural unit that can be installed as a single component. This merging reduces the overall complexity compared to using separate mounting elements, while still providing the reliability benefits of multiple attachment points and positioning features.
