Driver Seat Support Structure for Forward Cabin Space and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In purpose-built electric vehicles, maximizing occupant and baggage space while ensuring driver seat stability, collision safety, and reducing vibration and noise is challenging due to the need for efficient space utilization and secure seating arrangements.
Innovation Solution
A vehicle driver's seat structure is designed with an upwardly inclined dashboard floor panel, long-distance lower and upper seat supports, and a horizontally connecting upper floor, combined with vehicle frame cross members and brackets for enhanced stability and durability, allowing the seat to be positioned close to the vehicle front while maintaining foot space comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the driver's seat is arranged as close as possible to the vehicle front to maximize occupant and baggage space, then space utilization efficiency is improved, but the stability and support of the driver's seat may be compromised
Solution Approach 1:
The seat support structure is divided into multiple segments: lower seat support installed on the center floor panel, upper seat support installed on top of the lower seat support, and an upper floor horizontally connecting the upper seat support to the dashboard floor panel. This segmentation allows the driver's seat to be positioned forward while maintaining stability through distributed support points.
Solution Approach 2:
The support structure extends in multiple dimensions: the lower seat support extends over a long distance along the vehicle front-rear direction, the upper floor provides horizontal connection, and the upper seat support is positioned underneath the driver's seat. This multi-dimensional arrangement maximizes space utilization while ensuring seat stability.
2Productivity
If the driver's seat is positioned forward to maximize space utilization, then occupant space efficiency is improved, but collision safety and foot space comfort may be compromised
Solution Approach 1:
The upper floor is installed horizontally to connect the upper seat support and the dashboard floor panel before final seat installation, creating a preliminary stable structure that ensures both collision safety and foot space comfort while allowing forward seat positioning.
Solution Approach 2:
The upper floor acts as an intermediary element between the upper seat support and the dashboard floor panel, providing horizontal connection that simultaneously ensures collision safety, foot space comfort, and enables forward seat positioning for maximum space utilization.
3Stability of the object's composition
If the seat support structure is extended over a long distance to stabilize the driver's seat, then seat stability is improved, but the complexity of the structure increases
Solution Approach 1:
The lower seat support and upper seat support are merged into a integrated support system where the upper seat support is installed on top of the lower seat support, which extends over a long distance along the front-rear direction. This merging provides enhanced stability while managing structural complexity through functional integration.
