Monitor Attaching-Detaching Device for Aircraft Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitor assemblies in passenger mobile objects, such as aircraft, are difficult to attach and detach from wall surfaces due to the need for partial disassembly of the seat, making maintenance and replacement cumbersome.
Innovation Solution
A monitor assembly with an attaching-detaching device featuring a swing member and hinge mechanism that allows the monitor to be easily fixed and removed from a wall surface, utilizing parallel rod portions and lock assemblies for secure attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the monitor is fixed to the wall surface using conventional fixing methods, then the monitor is securely attached, but the attachment and detachment process becomes complex and time-consuming requiring partial disassembly of the seat
Solution Approach 1:
The fixing device is divided into separate components: a swing member with rod portions that can independently engage with lock assemblies, allowing the monitor to be attached and detached as a complete unit without disassembling the seat structure. The swing member segments the fixing function from the mounting structure.
Solution Approach 2:
The swing member is designed to be swingable between a first position (for attachment) and a second position (for detachment) via a hinge mechanism. This dynamic movement enables easy attachment and detachment operations while maintaining secure fixing when in the attached position.
2Adaptability or versatility
If the monitor is fixed using a tilt adjustment mechanism, then the monitor can be adjusted to different angles, but the detachment becomes difficult requiring partial disassembly of the seat
Solution Approach 1:
The tilt adjustment mechanism is segmented from the seat structure, with the swing member serving as an independent adjustable component that can be easily detached. This allows the monitor to maintain tilt adjustment capability while enabling simple removal for maintenance without seat disassembly.
Solution Approach 2:
The swing member with hinge mechanism is extracted as a separate detachable assembly from the seat structure. This extraction allows the monitor to be completely removed for maintenance by simply detaching the swing member, while the tilt adjustment function is preserved during operation.
3Reliability
If conventional fixing methods are used, then the monitor is securely mounted, but the time required for maintenance and replacement increases
Solution Approach 1:
The swingable mechanism enables rapid attachment and detachment through simple angular movements rather than complex assembly/disassembly operations. The hinge mechanism allows the swing member to be quickly positioned to engage or disengage from the lock assemblies, significantly reducing maintenance time while maintaining secure mounting.
Solution Approach 2:
The lock assemblies are designed to automatically engage with the rod portions when the swing member is in the first position, providing self-locking functionality. This eliminates the need for manual tightening or complex securing operations, allowing quick attachment while ensuring reliable mounting.

AI summary
A monitor detachably fixed to a wall surface includes an attaching-detaching device disposed between the monitor and the wall surface and configured to detachably fix the monitor to the wall surface. The attaching-detaching device includes a swing member having a distal end and a proximal end, a hinge mechanism configured to be attachable to the wall surface and support the proximal end of the swing member such that the distal end of the swing member is swingable to approach or leave the wall surface, a swing member engagement portion provided on a rear surface opposite to a display screen of the monitor and engaged with the swing member, and a lock mechanism provided on the rear surface of the monitor and configured to unlockably lock the swing member being engaged with the swing member engagement portion.
