Bulkhead Connection for Foldable Rear Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bulkhead connection system in motor vehicles requires multiple connection points to the ceiling and floor, increasing manufacturing costs and complicating the folding process of rear seats, which affects the efficiency and cost-effectiveness of vehicle design.
Innovation Solution
A motor vehicle design featuring a foldable rear seat with a bulkhead that connects to a locking element on the floor, allowing the bulkhead to be repositioned without additional external connection structures, using elements like hinges and spring pins for reliable folding and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bulkhead is connected to multiple connection points in the ceiling and floor to enable repositioning when the rear seat folds, then the adaptability of the bulkhead position is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The locking element is designed to perform multiple functions: it serves as both a connection point for the rear seat and a connection point for the bulkhead. This multi-functional design eliminates the need for separate connection structures, reducing complexity while maintaining the ability to reposition the bulkhead when the rear seat folds.
Solution Approach 2:
The patent merges the bulkhead connection structure with the existing rear seat locking mechanism. By integrating the bulkhead connection to the locking element that already exists in the rear seat, the design avoids adding separate connection points to the ceiling and floor, thereby reducing device complexity and manufacturing cost.
2Adaptability or versatility
If multiple connection points are provided in the ceiling and floor for bulkhead repositioning, then the bulkhead can be fixed in different positions, but the manufacturing cost increases
Solution Approach 1:
The locking element serves dual purposes: securing the rear seat and anchoring the bulkhead. This multi-functionality eliminates the need for additional connection points in the ceiling and floor, reducing the number of parts and assembly operations required, thereby lowering manufacturing cost.
Solution Approach 2:
The patent extracts the bulkhead connection function from the traditional ceiling-and-floor connection system and relocates it to the locking element. This extraction eliminates the need for multiple connection points in the vehicle structure, simplifying manufacturing.
3Adaptability or versatility
If the bulkhead is separated from the ceiling and floor for connection change, then the bulkhead position can be adjusted, but the process becomes inconvenient for users
Solution Approach 1:
The bulkhead connection is merged with the rear seat locking mechanism. When the rear seat is folded, the bulkhead automatically or easily connects to the locking element, which is already in a known position. This integration makes the repositioning process more intuitive and convenient for users compared to separating and reconnecting to multiple ceiling and floor points.
Solution Approach 2:
The locking element acts as an intermediary connection point between the bulkhead and the vehicle structure. This intermediary simplifies the repositioning process by providing a single, accessible connection point that is naturally accessed during the rear seat folding operation.
