Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display device mounting arrangements in aircraft are labor-intensive and time-consuming, requiring significant effort to install and repair, with space inefficiencies and security concerns for unauthorized detachment.
Innovation Solution
A mounting assembly with a locking mechanism and guide structure that allows for rapid attachment and detachment of display devices, using pivotable jaws with resilient biasing members and a release tool for secure and efficient installation and maintenance, while preventing unauthorized detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display devices are securely mounted to internal seat structure using conventional methods, then security against unauthorized detachment is improved, but installation and maintenance time increases significantly
Solution Approach 1:
The mounting system is divided into separate components: a mounting plate that attaches to the seat structure, a display device with bracket, and a locking mechanism with jaws. This segmentation allows the display device to be quickly attached and detached from the mounting plate without requiring disassembly of the entire seat structure, thus reducing installation and maintenance time while maintaining security through the locking mechanism.
Solution Approach 2:
The locking mechanism uses movable jaws that can transition between locked and unlocked positions. The jaws are biased by resilient members to automatically engage with the bracket edges when the display device is mounted, providing secure attachment. For maintenance or replacement, the jaws can be easily opened to release the device, significantly reducing the time required for installation and removal while maintaining security during normal operation.
2Stability of the object's composition
If display devices are securely mounted to internal seat structure, then mounting stability is improved, but labor intensity increases
Solution Approach 1:
The system separates the mounting plate (attached to seat) from the display device (with bracket), connected by a locking mechanism. This allows stable mounting through the locking jaws engaging the bracket edges, while reducing labor intensity by eliminating the need to disassemble seat structures for installation or replacement.
Solution Approach 2:
The resilient biasing members automatically engage the locking jaws with the bracket edges when the display device is positioned on the mounting plate. This self-actuating mechanism reduces the need for manual intervention and complex installation procedures, thereby reducing labor intensity while ensuring stable mounting through automatic engagement.
3Reliability
If conventional mounting arrangements are used, then secure electrical connections can be made, but space requirements increase due to need for connector access
Solution Approach 1:
The mounting plate integrates both the mechanical mounting function and the electrical connection function into a single component. The electrical connector is mounted on the mounting plate itself, positioned to mate with the display device connector when the device is attached. This merging eliminates the need for separate access spaces behind the monitor, reducing the area required while ensuring reliable electrical connections through the integrated connector arrangement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces installation and maintenance time, enhances security by requiring a release tool for detachment, and improves space efficiency by allowing 'blind' connector mating and reduced labor requirements.
Implementation Method 1
Each jaw includes a resiliently deformable biasing member connected to the jaw and biasing the jaw towards the closed position

AI summary
An assembly (10) for mounting a display device (12) in a vehicle. The assembly includes a mounting plate (16) having opposite edges, a front surface (18) extending therebetween, and a rear surface (20) opposite the front surface. The mounting plate is mountable to the vehicle with the front surface of the mounting plate facing outward. The assembly includes a first locking mechanism (28) disposed proximate one edge of the mounting plate and a second locking mechanism (28) disposed proximate the other edge. Each locking mechanism includes a jaw (30) extending over the front surface of the mounting plate and pivotable between closed and open positions. Each jaw includes a resiliently deformable biasing member (36) connected to the jaw and biasing the jaw towards the closed position. The assembly includes an electrical connector (46) attached to the mounting plate. The electrical connector has an opening for mating with another connector (48).
