Pivoting Display Mount With Tool-Free Locking Pin Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft electronic flight bags (EFBs) often require removal for updates, but existing securing and removal methods necessitate the use of special tools, which can complicate the process and degrade the viewing experience due to glare and height differences among flight crew members.
Innovation Solution
A pivoting display mounting apparatus comprising a base mount member, a pivot support member, and an upper mount member, where the pivot support member is coupled to the base mount member by a pivot pin and the upper mount member is secured using a locking pin that can be easily engaged and disengaged by hand without tools, allowing for adjustable tilt and removal of the EFB.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If EFBs are fixed in a position, then stability and secure mounting are improved, but viewing quality deteriorates due to glare and height differences among flight crew members
Solution Approach 1:
The mounting apparatus transforms the fixed mounting system into a dynamic one by introducing a pivot support member with rotation capability. The upper mount member can rotate relative to the base mount member through a defined range of motion, allowing the display to be adjusted to different angles and orientations. This dynamic adjustment enables optimal viewing angles for different crew members while maintaining secure mounting stability during flight.
2Adaptability or versatility
If EFBs are made portable for flexibility, then adaptability is improved, but tool-assisted removal and reinstallation become necessary for updates
Solution Approach 1:
The mounting apparatus introduces an intermediary locking mechanism consisting of a locking pin with T-handle and plunger that articulates locking balls. This intermediary device enables tool-free engagement and disengagement of the upper mount member from the base mount member. The locking balls engage with corresponding features to secure the display, while the plunger mechanism allows easy release by pressing, enabling rapid removal and reinstallation without specialized tools.
3Ease of operation
If tool-free removal is implemented, then ease of operation is improved, but secure mounting during flight may be compromised
Solution Approach 1:
The locking pin mechanism serves as a reliable intermediary that provides both easy operation and secure mounting. The locking balls, when engaged, create a positive mechanical lock that securely holds the upper mount member to the base mount member, preventing accidental disengagement during flight vibrations and movements. Simultaneously, the T-handle plunger design allows crew members to easily release the locking mechanism by simply pressing the plunger, achieving tool-free removal while maintaining flight safety.

AI summary
According to one aspect, a display mounting apparatus includes a base mount member, a pivot support member, and an upper mount member. The base mount member includes a pair of pivot attachment holes. The pivot support member includes an upper mounting surface and a locking pin passage. The pivot support member is coupled to the base mount member by a pivot pin that passes through the pair of pivot attachment holes. The upper mount member includes a display mounting surface, a lower surface, and a pair of locking pin holes arranged to engage a locking pin that passes through the pair of locking pin holes and through the locking pin passage of the pivot support member when the upper mounting surface of the pivot support member is positioned proximate to the lower surface of the upper mount member.
