Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail slide systems for snowmobiles require multiple molds for different lengths, leading to increased costs and inefficiencies, and often generate heat due to the use of bogie wheels, which can affect performance and fuel economy.
Innovation Solution
A modular rail slide system composed of interchangeable modules with inserts, allowing for various lengths to be created using a single mold, eliminating the need for bogie wheels and reducing heat generation through injection molding with durable, low-friction materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple molds are used for different rail slide lengths, then various lengths can be produced, but production costs and device complexity increase
Solution Approach 1:
The rail slide is divided into multiple interchangeable modules that can be coupled together in different combinations. Each module has standardized coupling ends with inserts, allowing them to be assembled in series to achieve different total lengths. This segmentation enables a single mold to produce all module types, eliminating the need for multiple specialized molds while providing length adaptability.
2Reliability
If bogie wheels are used in rail slide systems, then support and stability are improved, but heat generation increases affecting performance and fuel economy
Solution Approach 1:
The bogie wheels are completely removed from the rail slide system. Instead of using wheels to support the track, the invention employs a direct sliding contact system where the track engages with the modular rail slide assembly. This extraction of the harmful element (bogie wheels) eliminates the source of excessive heat generation while maintaining support functionality through the sliding mechanism.
Solution Approach 2:
The sliding contact between the track and modular rail slide assembly, which could potentially generate friction heat, is optimized through the insert design. The inserts are made from low-friction materials that convert the potential harmful friction into beneficial controlled sliding resistance, providing necessary support while minimizing heat generation. The friction that remains is optimized to be just enough for support without excessive heat.
3Productivity
If interchangeable modules with inserts are used, then production efficiency and cost are improved, but assembly complexity may increase
Solution Approach 1:
All rail slide modules are designed with universal coupling ends that feature identical insert configurations and coupling geometries. This universality allows any module to be coupled with any other module in any orientation, simplifying the assembly process despite the modular structure. The standardized interface eliminates the need for complex assembly procedures, as modules can be quickly connected and disconnected using the same coupling mechanism throughout the entire system.
