Aircraft Cabinet Integrating Avionics Modules with Flight Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing structures for supporting flight equipment in aircraft are bulky, complex, and heavy, making it difficult to maintain proximity between flight-control screens and avionics modules, leading to long data transmission cables and limited space for maintenance.
Innovation Solution
Aircraft cabinet design where avionics modules are integrated within the structure supporting the screens, allowing the screens to be placed at desired heights, with removable and articulated designs for easy access and reduced cabling, and incorporating storage compartments for equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If avionics modules are placed in a separate avionics bay away from the cockpit, then space for maintenance and cooling is improved, but the length of data transmission cables increases and weight increases
Solution Approach 1:
The cabinet is divided into a front part containing the screen and a rear part containing the avionics module, allowing them to be separated functionally while physically integrated. This segmentation enables maintenance access to the avionics module through the removable front part while keeping the overall structure compact and close to the cockpit.
Solution Approach 2:
The avionics module is nested within the cabinet structure that also houses the screen. The module is positioned in the rear part of the same cabinet unit, eliminating the need for separate remote mounting and reducing cable length while maintaining organized integration of components.
2Volume of stationary object
If traditional vertical enclosures with racks are used, then space utilization is improved, but the structure becomes bulky and complex
Solution Approach 1:
The screen support structure and the avionics module housing are merged into a single integrated cabinet unit. The front part of the cabinet serves both as the screen mounting structure and as the access door to the avionics module, eliminating the need for separate racks and mounting structures.
Solution Approach 2:
The cabinet structure serves multiple functions: it supports the screen, houses the avionics module, provides maintenance access, and contains cooling/ventilation components. The front part acts as both a structural support element and an access door, reducing overall structural complexity.
3Illumination intensity
If screens are mounted at pilot eye level in the cockpit, then visibility is improved, but the structure becomes heavy and complex due to support requirements
Solution Approach 1:
The screen is merged with the avionics module housing into a single cabinet unit. The screen forms part of the front face of the cabinet, eliminating the need for separate heavy mounting structures while maintaining proper positioning for pilot visibility.
Solution Approach 2:
The cabinet base provides adjustable height positioning for the screen, allowing it to be placed at the desired pilot eye level without requiring an overly complex adjustable mounting mechanism. The base structure provides sufficient support with minimal complexity.
Data Source
AI summary
A cabinet comprising at least one screen allowing display of data necessary for a flight-control of an aircraft connected to at least one avionics module for management of the data. The screen at least partially forms one of the sides of the cabinet and the module or modules are installed inside the cabinet. The cabinet has a base allowing the screen or screens to be placed at a desired height. As a result, a length of cable between screen and avionics modules is reduced to a minimum.
