Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a simple and rapid method to install and remove an additional screen on an aircraft instrument panel without modifying the existing equipment.
Innovation Solution
A fastening system comprising a rectilinear rail, a fastening device, and a movable carriage with a support device that allows the screen to be easily installed and removed by translational and pivoting movements, utilizing a rectilinear rail, fastening components, and self-gripping attachment means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional screen is installed on the instrument panel, then the functionality and versatility of the cockpit is improved, but the complexity of the equipment and difficulty of installation increases
Solution Approach 1:
The fastening system is divided into separate modular components: a rectilinear rail fixed to the instrument panel, a movable carriage that slides along the rail, and a support device with pivotable brackets. This segmentation allows each component to perform its specific function independently, simplifying the overall installation process while maintaining versatility.
Solution Approach 2:
The rectilinear rail serves multiple functions: it provides a mounting structure for the instrument panel, a guide for the movable carriage, and a support for the pivotable brackets. This multi-functionality reduces the need for additional specialized components, thereby reducing equipment complexity while enhancing adaptability.
2Reliability
If an additional screen is permanently installed on the instrument panel, then the stability and reliability of the screen positioning is improved, but the ease of removal and adaptability decreases
Solution Approach 1:
The support device incorporates pivotable brackets that can rotate between a locked position (providing stable screen positioning) and an unlocked position (enabling easy removal). The movable carriage can also slide along the rail to adjust screen position dynamically. This dynamic design allows the system to switch between stable operation and easy reconfiguration as needed.
3Strength
If a complex fastening system is used to secure the screen, then the strength and stability of the connection is improved, but the ease of installation and removal deteriorates
Solution Approach 1:
The pivotable brackets are designed to engage with the rectilinear rail through self-latching mechanisms that automatically lock when the bracket is rotated into position. This self-service feature provides strong connection strength without requiring complex manual fastening operations, thereby maintaining ease of installation and removal.
