Modular Passenger Seat System with Detent Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of rearranging passenger seats in vehicles, such as aircraft and buses, is cumbersome and time-consuming, requiring a more efficient system for quick and easy reconfiguration.
Innovation Solution
A modular passenger seat system featuring a seat leg with a tube that fits into a bushing on the vehicle floor, utilizing detent members and a biasing mechanism to securely attach and detach the seat, allowing for easy installation and removal, along with a lock and depressible button for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional passenger seat arrangement methods are used, then seats can be secured to the vehicle floor, but the process is cumbersome and time-consuming
Solution Approach 1:
The seat leg is divided into multiple segments that can be independently positioned and locked. The telescopic mechanism allows the seat leg to be segmented into extendable and retractable portions, enabling quick adjustment and reconfiguration without moving the entire seat assembly.
Solution Approach 2:
The seat leg incorporates a telescopic mechanism with movable segments that can dynamically adjust length and position. This dynamic structure allows rapid reconfiguration of seat arrangements by extending or retracting leg segments, significantly reducing the time required compared to fixed-seat installations.
2Reliability
If a secure attachment mechanism is used to firmly secure seats to the vehicle floor, then reliability is improved, but the device complexity increases
Solution Approach 1:
The detent mechanism is nested within the telescopic seat leg structure. The detent members are housed inside the leg segments and automatically engage with corresponding features on the vehicle floor, providing secure attachment without requiring external complex locking mechanisms.
Solution Approach 2:
The detent mechanism operates automatically through the telescopic motion of the seat leg. As the leg extends or retracts, the detent members self-engage or self-disengage from the vehicle floor mounting points, eliminating the need for manual locking operations or complex control systems.
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 rapid reconfiguration of seating layouts, saving time and reducing costs by simplifying the process of rearranging passenger seats while ensuring secure attachment to the vehicle floor.
Implementation Method 1
The modular passenger seat system includes a biasing member disposed within the tube
Implementation Method 2
Each of the first detent member and the second detent member is configured to extend through a respective one of the first aperture and the second aperture and contact a lower portion of the bushing when the tube is received within the bushing to retain the tube therein

AI summary
A modular passenger seat system includes a passenger seat having a seat leg with a distal end portion. The distal end portion includes a tube. The tube includes a sidewall having a first aperture and a second aperture. The modular passenger seat system includes a first detent member and a second detent member disposed within the first aperture and the second aperture in the sidewall of the tube. Each of the first detent member and the second detent member is configured to extend through the first aperture and the second aperture when the tube is received within the bushing. The modular passenger seat system includes a shaft movably disposed within the seat leg. The shaft has a lower end which when displaced against a biasing member enables the first detent member and the second detent member to retract inwardly into the tube.
