Segmented Passenger Seat System for Cabin Monument Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to increase passenger capacity in vehicles while maintaining comfort, particularly in aircraft cabins, where existing designs struggle to optimize space utilization without compromising passenger comfort or safety.
Innovation Solution
A functional unit in the passenger cabin comprising a support unit and a passenger seat system, divided into upper and lower constructional units, where the upper unit includes a backrest configured for safety in monuments (dynamic 9 g loadings) and the lower unit includes a seat frame and restraint configured for aircraft passenger seats (dynamic 16 g loadings), allowing efficient space use by forming a passenger seat directly on cabin monuments without visible separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If passenger capacity is increased while keeping vehicle dimensions the same, then space utilization is improved, but passenger comfort is restricted
Solution Approach 1:
The passenger seat system is divided into two independent constructional units: an upper unit (backrest and headrest) and a lower unit (seat frame, seat element, and restraint). This segmentation allows the upper unit to be mounted on the cabin monument while the lower unit is fastened to seat rails, enabling flexible space utilization near monuments without compromising seat safety or comfort standards
Solution Approach 2:
The cabin monument is given multiple functions: it serves as both a structural element and a mounting support for the upper constructional unit of the passenger seat. This multi-functionality allows efficient use of existing cabin space for passenger seating without requiring additional floor space, thereby increasing passenger capacity while maintaining comfort
2Quantity of substance
If cabin monuments are used for multiple functions, then space utilization is improved, but device complexity increases
Solution Approach 1:
The seat system is segmented into upper and lower constructional units that can be independently installed and configured. The upper unit mounts to the cabin monument while the lower unit connects to seat rails, creating a modular system that simplifies installation and maintenance while maximizing space utilization near monuments
Solution Approach 2:
The upper constructional unit acts as an intermediary element that connects the cabin monument to the lower seat unit. This intermediary component enables the integration of monument space into the seating system without requiring complex direct integration, thereby reducing overall system complexity while improving space utilization

AI summary
A functional unit in a passenger cabin includes a support unit and a passenger seat system. The passenger seat system is formed in two parts and has an upper constructional unit and a lower constructional unit that are each separate components, the upper constructional unit arranged on the support unit and containing at least one backrest, and the lower constructional unit containing a seat frame, at least one seat element and restraint for the passenger on the seat. The seat frame is fastenable to seat rails on the floor of a passenger cabin. For the use position, the upper and lower constructional units are positioned such that a passenger seat is formed. In the use position, personal comfort for the individuals on the seats is not impaired as far as possible, and the division of the seat system into two parts cannot be seen by the user.
