EV Battery Tunnel Console Storage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles face challenges due to the bulkiness and weight of batteries, which pose safety risks during collisions and require innovative structural solutions to protect both the vehicle and passengers from battery damage.
Innovation Solution
The design incorporates a rigid tunnel within the passenger compartment to cover a portion of the battery assembly, using lightweight yet strong materials like aluminum or carbon fiber, which also serves as a protective barrier and allows for easy battery replacement, and includes a center console with a storage area defined by the space between the tunnel and console surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid tunnel is added to cover the battery assembly, then safety and structural integrity are improved, but device complexity increases
Solution Approach 1:
The rigid tunnel is designed to serve multiple functions simultaneously: it acts as a protective barrier for the battery assembly, provides structural support for the center console, and creates a sealed separation between the passenger compartment and battery. This multi-functionality approach allows the single structural element to improve safety without proportionally increasing device complexity.
Solution Approach 2:
The center console is positioned within and supported by the rigid tunnel structure, with the tunnel enclosing the console while the console utilizes the tunnel's structural framework. This nesting arrangement allows the console to benefit from the tunnel's protective and structural functions without requiring separate support structures, thereby improving safety while minimizing additional complexity.
2Ease of operation
If the center console is positioned on top of the rigid tunnel, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The rigid tunnel serves as both a protective enclosure for the battery and a structural support platform for the center console. By positioning the console on top of the tunnel, the design eliminates the need for separate mounting structures, thereby improving ease of operation while avoiding proportional increases in device complexity.
3Reliability
If the passenger compartment is sealed from the battery assembly, then safety is improved, but manufacturing precision requirements increase
Solution Approach 1:
The rigid tunnel acts as an intermediary structure that provides a sealed barrier between the passenger compartment and battery assembly. By introducing this intermediate protective element, the design achieves effective separation and safety without requiring extremely tight sealing between the battery and passenger compartment components directly, thereby reducing the overall manufacturing precision requirements while maintaining safety.

AI summary
A storage area for an electric vehicle includes a rigid tunnel positioned within a passenger compartment of the electric vehicle. The tunnel covers a portion of a battery assembly that extends above a floor structure of the vehicle such that the passenger compartment is sealed from the battery assembly. A center console is positioned within the passenger compartment. The center console is disposed on top of the tunnel such that a medial portion of the center console is spaced a vertical distance above a top surface of the rigid tunnel. A first end and a second end of the center console are coupled with the top surface of the rigid tunnel. A thickness of the medial portion is less than that of the first end and the second end. A space between the top surface of the tunnel and a bottom surface of the medial portion defines the storage area.
