Aircraft Seat Track Foot and Roller Layout for Stable Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft seat translating systems face issues with stability and degrees of freedom due to separately positioned track feet and rollers, which lead to unnecessary space competition and instability during translation.
Innovation Solution
The proposed tracking system includes a track foot with axles that interface with the aircraft seat track and roller bearings that couple to the axles, positioned on the top surface of the track to enhance stability and smooth translation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If track feet and rollers are separately positioned, then the system can be simplified in design, but the stability and degrees of freedom deteriorate due to space competition and instability during translation
Solution Approach 1:
The patent combines the track foot and rollers into a single integrated assembly where the rollers are mounted on the track foot structure. This merging eliminates the separate positioning of track feet and rollers, resolving the space competition issue while maintaining structural simplicity. The integrated design allows the rollers to be properly supported by the track foot, improving translation stability without significantly increasing device complexity.
2Device complexity
If rollers are positioned within the center of the track and biased towards the middle portion, then the system structure is simplified, but the rollers bounce off the attachment countersinks and create imbalance during translation
Solution Approach 1:
The patent positions the rollers at specific locations on the track foot that are optimized for their function. Rather than placing them centrally, the rollers are positioned to interface with the top surface of the track at points that avoid the attachment countersinks. This local optimization of roller position ensures smooth translation by preventing bouncing off the countersinks while maintaining a relatively simple positioning system.
3Device complexity
If rollers are constrained to a fixed position, then the system structure is simplified, but the degrees of freedom are reduced and rocking movement occurs during track roll
Solution Approach 1:
The patent designs the roller mounting on the track foot to allow dynamic adjustment. The rollers are positioned to contact the top surface of the track in a way that permits natural movement and adaptation during translation and rolling operations. This dynamic positioning allows the system to maintain stability while accommodating the degrees of freedom needed for smooth operation, preventing rocking movement without requiring complex constraint systems.

AI summary
An aircraft seat may include an integrated tracking system. The tracking system may include at least one track foot and one or more roller bearings. The track foot may include one or more axles and be able to interface with a portion of an aircraft seat track. The one or more roller bearings may be coupled to the one or more axles of the track foot and interface with a top surface of the aircraft seat track to aid in the translation of the aircraft seat.
