EV Skateboard Platform With Integrated Swappable Battery Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skateboard platforms for electric vehicles have a structure where the battery assembly overlaps the skateboard frame, increasing weight and cost due to unnecessary space and additional components.
Innovation Solution
A skateboard platform design where the battery assembly is integrally connected to the center module of the skateboard frame, reducing the number of components and weight by uniformly distributing stiffness, and allowing for easy detachment and swappability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the battery assembly overlaps the skateboard frame in a conventional skateboard platform, then the battery assembly can be mounted on the frame, but the weight and cost increase due to unnecessary space and additional components
Solution Approach 1:
The battery assembly is integrated with the skateboard frame to form a unified structure, eliminating the conventional overlapping arrangement. The battery case is positioned to overlap the longitudinal center line of the skateboard frame, merging the battery assembly with the frame structure itself, thereby removing unnecessary space and components while maintaining mounting capability
Solution Approach 2:
The skateboard frame structure is designed to serve multiple functions: it provides the structural foundation for the vehicle and simultaneously serves as the mounting structure for the battery assembly. The integrated design allows the frame to fulfill both structural support and battery mounting roles, eliminating the need for separate mounting components
2Strength
If the battery assembly is integrally connected to the center module of the skateboard frame, then the overall stiffness is increased and components are reduced, but the design complexity increases
Solution Approach 1:
The skateboard frame is divided into modular sections including a front module, a center module, and a rear module. The battery assembly is specifically integrated with the center module, allowing for segmented design that simplifies the overall structural complexity while maintaining integral connection benefits for stiffness enhancement
