Removable Seat Surface Attachment for Rapid Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Known seat assemblies for vehicles, such as aircraft, are not easily reconfigurable and require full disassembly to change from a passenger seat to a utility element, making reconfiguration time-consuming and costly.
Innovation Solution
A seat assembly with a base structure that includes a seat pan shell and a backrest shell, equipped with attachment structures allowing for removable coupling to either a seat surface arrangement or a utility surface arrangement, enabling conversion between passenger seat and utility element configurations without full disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If known seat assemblies use fixed base structures with cushions detachably attached, then the seat assembly is simple in structure, but it cannot be easily reconfigured for different purposes
Solution Approach 1:
The base structure is designed with universal attachment structures that can accommodate both seat surface arrangements and utility surface arrangements. The same base structure serves multiple functions by accepting different surface arrangements, enabling conversion between passenger seat and utility element configurations without requiring separate base structures for each purpose.
Solution Approach 2:
The seat assembly is divided into separable components: a base structure with attachment structures, seat surface arrangements, and utility surface arrangements. This segmentation allows the surface arrangements to be independently attached or removed from the base structure, enabling easy reconfiguration between different uses while maintaining structural simplicity.
2Productivity
If known seat assemblies require full disassembly to change from passenger seat to utility element, then the conversion is complete, but the process is time-consuming and costly
Solution Approach 1:
The seat assembly is segmented into a base structure and interchangeable surface arrangements. This allows only the surface arrangement to be removed and replaced while the base structure remains in place, significantly reducing the time and cost required for reconfiguration compared to full disassembly of the entire seat assembly.
Solution Approach 2:
The attachment structures are pre-configured on the base structure during manufacturing, enabling rapid attachment and detachment of surface arrangements during operation. The preliminary preparation of attachment interfaces allows for quick swaps between seat and utility configurations without requiring complex disassembly procedures.
3Adaptability or versatility
If known seat assemblies use fixed configurations, then the structure is stable and simple, but it cannot provide additional utility features
Solution Approach 1:
The base structure is designed with universal attachment structures that can accommodate both seat surface arrangements and utility surface arrangements. The same base structure serves multiple functions by accepting different surface arrangements, enabling conversion between passenger seat and utility element configurations without requiring separate base structures for each purpose.
Solution Approach 2:
The seat assembly transitions from a static fixed configuration to a dynamic reconfigurable system. The attachment structures enable the surface arrangement to be changed based on operational needs, allowing the same base structure to adapt between passenger seating and utility element functions, providing flexibility and additional utility features.

AI summary
A seat assembly includes a base structure having at least one of a seat pan shell and a backrest shell, and one or more attachment structures configured to removably couple at least one of the seat pan shell and the backrest shell to a seat surface arrangement or a utility surface arrangement. The base structure is convertible between a passenger seat and a utility element based on the coupling of the seat surface arrangement or the utility surface arrangement, respectively, to the base structure.
