Snowmobile Sled Module Rack System for Tunnel Cargo Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Snowmobiles have limited cargo capacity due to their tunnel being made of pliable materials that deform under weight, and existing solutions for stiffening the tunnel are difficult to install and remove, lacking a dedicated cargo area.
Innovation Solution
A sled module with a rack system that attaches to the snowmobile's tunnel, featuring adjustable support rods and attachment holes for securing gear, including a grab bar for lifting and a strap system for securing cargo, allowing easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cargo is placed on the tunnel, then cargo capacity is improved, but the tunnel deforms and comes into contact with the moving treads causing damage or inoperability
Solution Approach 1:
The sled module is divided into separate components: a rack structure that attaches to the tunnel, support rods that can be positioned independently, and a base structure. This segmentation allows the cargo-carrying function to be separated from the tunnel structure itself, enabling cargo capacity improvement without compromising tunnel integrity.
Solution Approach 2:
The rack structure serves as an intermediary between the tunnel and the cargo. Instead of placing cargo directly on the tunnel, the rack acts as a mediator that distributes and supports the cargo weight, preventing direct contact between cargo and the tunnel material while maintaining structural integrity.
2Quantity of substance
If tunnel stiffeners are installed to strengthen the tunnel, then cargo capacity is improved, but installation becomes difficult requiring drilling holes and permanent attachments
Solution Approach 1:
The sled module employs adjustable and removable components rather than permanent fixed structures. The rack can be attached and detached, and the support rods can be repositioned, transforming the static permanent attachment system into a dynamic adjustable system that is easier to install, remove, and adapt.
Solution Approach 2:
The system allows for parameter changes in terms of configuration and attachment points. The support rods can be adjusted to different positions, and the rack can be attached at various locations, providing flexibility in installation without requiring permanent modifications to the snowmobile structure.
3Strength
If tunnel stiffeners are used to create a cargo platform, then structural strength is improved, but the system lacks dedicated cargo areas and securement mechanisms
Solution Approach 1:
The sled module is designed as a multi-functional system that combines structural support, cargo platform creation, and securement mechanisms in one integrated assembly. The rack provides both structural reinforcement and serves as a mounting platform for various cargo items, while the support rods and attachment points provide versatile securing options for different types and sizes of cargo.
Solution Approach 2:
The sled module extends the cargo-carrying capability into a new dimensional space above the tunnel, creating a three-dimensional cargo area rather than merely reinforcing the existing two-dimensional tunnel surface. This adds vertical utilization of space and creates dedicated cargo zones that were not present in the original tunnel structure.
