Pivoting Display Mount Assembly for Multi-Position Aircraft Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
First class aircraft suites lack the ability to adjust display screen mounting for optimal viewing angles, as current mounts are fixed and rigid due to safety and environmental constraints, preventing passengers from comfortably viewing the screen from both seated and lying positions.
Innovation Solution
A motorized mount assembly with a triangular frame structure, comprising a base support frame, pivoting support frame, and carriage frame, allowing the display to be dynamically positioned between stowed and deployed angles, enabling viewing from various locations, including seats and beds, with a motor and clutch system for controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed, rigid mount assembly is used to meet safety and environmental constraints, then the display can be securely mounted to withstand extreme load conditions, but the display cannot be adjusted to different viewing angles for comfortable viewing from various positions
Solution Approach 1:
The mount assembly transitions from a fixed, rigid structure to a dynamic system with multiple movable components. The pivoting support frame allows angular adjustment, the carriage frame provides linear movement along the drive shaft, and the motorized system enables controlled transitions between different viewing positions while maintaining stability when positioned
2Ease of operation
If a motorized movement system is added to enable position adjustment, then the display can be dynamically positioned for viewing from different locations, but the device complexity increases
Solution Approach 1:
The patent replaces complex manual mechanical adjustment mechanisms with a motorized drive system. The motor, drive shaft, and carriage assembly provide automated, controlled movement, eliminating the need for manual manipulation of multiple mechanical joints and making the system easier to operate despite the added motorization
3Adaptability or versatility
If the display mount is made movable and adjustable, then passengers can view the display from seated and lying positions, but the mount may not withstand extreme load conditions during takeoff, landing, and turbulence
Solution Approach 1:
The mount assembly is divided into segmented components: a base support frame that remains fixed to the aircraft structure, a pivoting support frame that can rotate, and a carriage frame that moves linearly. This segmentation allows the fixed base to handle extreme loads while the movable segments provide viewing position flexibility
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
Enables passengers to easily and safely adjust the display screen's viewing angle, ensuring comfort and convenience, while meeting safety and load-bearing requirements, such as supporting up to 200 lbs, and accommodating different passenger positions during flight.
Implementation Method 1
a motor in operative communication with the carriage and adapted to impart a motive force on the carriage for transitioning the carriage frame between the stowed position and the deployed position
Implementation Method 2
a clutch in selective communication with the motor and the carriage frame, the clutch being selectively transitional between an engaged position and a disengaged position

AI summary
A mount assembly for dynamically positioning a display to a mounting surface. The assembly comprises a base support frame and a pivoting support frame pivotally coupled thereto and defining a pivot angle in between, with the pivoting support frame being transitional between first and second positions, the pivot angle increasing as the pivot support frame transitions from the first position toward the second position. A carriage frame adapted to be engaged with the display, and having a first attachment portion is pivotally and translatably coupled to the base support frame and defines a carriage angle therebetween, and a second attachment portion is pivotally coupled to the pivoting support frame. The carriage frame is transitional relative to the base support frame between stowed and deployed positions, the carriage angle increasing as the carriage transitions from the stowed position to the deployed position.
