Battery Pack Spacer Mounting for Electric Snowmobile Subframes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The electrification of snowmobiles poses challenges due to the need for proper weight balance and ease of assembly, as well as the logistical complexity and cost of offering different battery packs and frames for various vehicles.
Innovation Solution
The use of spacers to connect the battery pack to the subframe in an electric snowmobile, allowing for flexible assembly with different frames and battery packs, while maintaining proper weight distribution and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different battery packs and frames are provided for each vehicle configuration, then proper weight balance and vehicle performance can be achieved, but manufacturing cost and logistical complexity increase
Solution Approach 1:
The spacer is designed as a universal mounting component that can accommodate multiple battery pack configurations and frame types. The spacer includes multiple mounting surfaces and attachment points that allow it to interface with different battery pack sizes and shapes, as well as different frame configurations, enabling a single spacer design to serve multiple vehicle assembly variations without requiring configuration-specific parts
Solution Approach 2:
The mounting system is segmented into modular components: the frame, the spacer as an intermediate mounting element, and the battery pack. This segmentation allows the spacer to act as a flexible interface that can be positioned at different locations on the frame to achieve proper weight balance for different battery pack configurations, without requiring custom-integrated solutions for each vehicle type
2Reliability
If multiple specific battery pack and frame combinations are manufactured, then proper weight distribution can be ensured, but manufacturing cost increases
Solution Approach 1:
The spacer is designed as a universal mounting component that can accommodate multiple battery pack configurations and frame types. The spacer includes multiple mounting surfaces and attachment points that allow it to interface with different battery pack sizes and shapes, as well as different frame configurations, enabling a single spacer design to serve multiple vehicle assembly variations without requiring configuration-specific parts
Solution Approach 2:
The mounting system incorporates adjustable positioning capabilities where the spacer can be positioned at different locations on the frame depending on the battery pack configuration. This dynamic positioning allows proper weight distribution to be achieved across different vehicle configurations using the same spacer design, eliminating the need for configuration-specific mounting solutions
3Stability of the object's composition
If battery packs are securely mounted to the frame, then vehicle stability is improved, but assembly complexity increases
Solution Approach 1:
The spacer serves as an intermediary mounting component between the frame and the battery pack. This intermediate element provides a standardized interface that simplifies assembly by decoupling the mounting requirements from the specific battery pack or frame configuration, allowing secure mounting through a uniform attachment process regardless of the specific components being assembled

AI summary
An electric snowmobile has a frame. The frame has a tunnel; a subframe connected to the tunnel and having first and second sides; and first and second spacers connected the first and second sides respectively. The snowmobile also has a seat; at least one ski a drive track disposed at least in part under the tunnel; an electric motor supported by the frame, the electric motor being operatively connected to the drive track; and a battery pack electrically connected to the electric motor, the battery pack being disposed at least in part in the subframe. The first spacer is disposed between the first side of the subframe and the battery pack. The second spacer is disposed between the second side of the subframe and the battery pack. The first and second spacers connect the battery pack to the first and second sides of the subframe respectively.
