Solution Overview
Problem
First class aircraft suites lack the ability to adjust display screens for optimal viewing angles, as existing mounts are rigid and do not accommodate passengers in both seated and reclined positions due to safety and load constraints.
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 transition between stowed and deployed positions, enabling adjustable viewing angles and supporting loads up to 200 lbs, with a motor-driven mechanism and clutch for manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed rigid mount is used to secure the display to the wall, then the display remains stable and meets safety requirements, but the display cannot be adjusted to different viewing angles for passengers in different positions
Solution Approach 1:
The mount is divided into multiple independent components: a base plate fixed to the wall, an arm with pivot joints, and a display holder. This segmentation allows each component to perform a specific function while enabling overall adjustability without excessive complexity.
Solution Approach 2:
The mount transitions from a static rigid structure to a dynamic adjustable structure through the incorporation of pivot joints and locking mechanisms. The arm can rotate and adjust to different angles, allowing the display to be positioned for optimal viewing from various passenger locations while maintaining stability when locked in place.
2Ease of operation
If a motorized mechanism is added to enable display positioning, then viewing comfort is improved, but the device complexity and potential safety risks increase
Solution Approach 1:
The mount incorporates a manual crank mechanism that allows passengers to independently position the display themselves without requiring electrical power or complex motorized systems. This self-service approach improves ease of operation while maintaining reliability by using simple mechanical components that are inherently more reliable than motorized systems.
3Strength
If the mount is designed to support heavy loads for safety, then structural strength is improved, but the overall weight of the mount increases
Solution Approach 1:
The mount utilizes composite construction combining aluminum alloy frames with steel reinforcement at critical stress points. This allows the overall structure to be lightweight while maintaining sufficient strength to support heavy loads, as the steel reinforcement is strategically placed only where needed rather than throughout the entire structure.
Solution Approach 2:
The arm components feature curved and angled geometries that optimize structural efficiency. The curved shapes distribute stresses more effectively throughout the material, allowing thinner walls and less material to achieve the same load-bearing capacity, thereby reducing weight while maintaining strength.

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.
