Modular Seat Assembly with Carrier Frame for Simplified Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seat assembly designs can be complex and difficult to assemble, particularly due to large components that are hard to manipulate and align properly within a vehicle.
Innovation Solution
A modular seat assembly with a carrier frame that allows adjustable connection of seatback portions, enabling easy alignment and assembly by connecting the upper and lower portions of the seatbacks and intermediate sections to form a cohesive seatback section, facilitated by a sliding track system for lateral adjustment.

Engineering Contradiction Analysis
1Strength
If large components are used in seat assembly, then structural strength is improved, but ease of assembly deteriorates due to difficulty in manipulation and alignment
Solution Approach 1:
The seat assembly is divided into multiple modular components including a carrier frame, seat bottom assembly, and seatback assembly. These modules can be manufactured separately and assembled together, making it easier to handle and align large components during assembly while maintaining overall structural strength through standardized connection interfaces.
Solution Approach 2:
The carrier frame serves as an intermediary component that facilitates the connection between the seat bottom assembly and seatback assembly. It provides standardized mounting points and connection mechanisms that simplify the alignment and assembly process while distributing structural loads effectively across the entire seat assembly.
2Ease of operation
If modular components are used, then ease of assembly is improved, but device complexity increases due to multiple parts
Solution Approach 1:
The carrier frame performs multiple functions: it serves as the structural backbone, provides mounting points for both seat bottom and seatback assemblies, and incorporates connection mechanisms for adjustable configurations. This multi-functionality reduces the need for additional separate components, thereby simplifying the overall device despite its modular nature.
Solution Approach 2:
The connection mechanisms and adjustment mechanisms are integrated into the carrier frame and seat assemblies rather than being separate components. This merging of functions into unified modules reduces the total number of parts while maintaining ease of assembly through standardized interfaces.

AI summary
A seat assembly includes a first seatback and a second seatback. The first seatback may include a first seatback upper portion and a first seatback lower portion. The second seatback may include a second seatback upper portion and a second seatback lower portion. The seat assembly may further include an intermediate back section including an intermediate upper portion and an intermediate lower portion. The first seatback lower portion and the second seatback lower portion may be arranged on opposite sides of the intermediate lower portion. The seat assembly may also include a carrier frame to which the first seatback upper portion, the second seatback upper portion, and the intermediate upper portion may be connected. At least one of the first seatback upper portion, the second seatback lower portion, and the intermediate upper portion may be adjustably connected to the carrier frame.
