Modular Off-Road Trailer Suspension for Multi-Terrain Towing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicle trailers are typically designed for specific load types and terrains, requiring multiple trailers for varying conditions, leading to increased ownership and maintenance costs, as well as storage challenges due to varying payload characteristics affecting tongue weight.
Innovation Solution
An adjustable off-road trailer with a suspension assembly and center beam system that allows for different trailer bed lengths and terrain modules, featuring a torsion axle assembly for suspension without additional shock absorbers, and modular design for compact packaging and multi-season use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specialized trailers are purchased for different terrains and load types, then adaptability to various conditions is improved, but ownership costs and maintenance costs increase
Solution Approach 1:
The trailer is designed with a universal configuration system that allows a single trailer to perform multiple functions across different terrains and load types. The adjustable tongue length, interchangeable ground engagement components (skis, wheels, tracks), and modular terrain modules enable one trailer to replace multiple specialized trailers, reducing ownership and maintenance costs while maintaining adaptability.
Solution Approach 2:
The trailer incorporates dynamic adjustability features including adjustable tongue length, interchangeable ground engagement components, and adjustable terrain modules that can be configured based on current operating conditions. This dynamic reconfiguration capability allows the trailer to adapt to varying terrains and payload characteristics without requiring multiple fixed-configuration trailers.
2Adaptability or versatility
If multiple trailers are purchased for different seasons and vehicle types, then versatility across conditions is improved, but storage space requirements increase
Solution Approach 1:
The trailer is designed as a universal platform that can be configured for different seasons and vehicle types through interchangeable components. A single trailer with adjustable features replaces multiple season-specific and vehicle-type-specific trailers, significantly reducing the storage space required while maintaining versatility across snowmobiles, ATVs, and other off-road vehicles throughout the year.
3Stability of the object's composition
If trailer tongue length is fixed for specific payload characteristics, then tongue weight stability is improved, but adaptability to varying payloads decreases
Solution Approach 1:
The trailer features an adjustable tongue length mechanism that allows the tongue to be repositioned along the center beam assembly to accommodate varying payload characteristics. This dynamic adjustment capability maintains optimal tongue weight stability for different payload weights, sizes, and center of gravity positions, eliminating the need for multiple fixed-tongue trailers.
4Device complexity
If suspension assembly is positioned at fixed locations on the center beam, then structural simplicity is improved, but adaptability to different configurations decreases
Solution Approach 1:
The suspension assembly is designed with adjustable positioning capability along the center beam assembly, allowing it to be relocated to different positions to accommodate varying payload characteristics and terrain conditions. This maintains structural simplicity while enabling adaptability to different configurations through straightforward repositioning rather than complex redesign.

AI summary
A trailer for use with off-road vehicles such as all-terrain vehicles and snowmobiles. The disclosed off-road trailer can be adjusted to accommodate different trailer beds and attachments that can be readily off loaded and can be compactly packaged for shipping and storage. Modules for different conditions (e.g., ground or snow surface) can be implemented for multi-season usage. The disclosed suspension assembly enhances performance and robustness while maintaining cost effectiveness. The utility of the disclosed off-road trailer may be enhanced by grab handles for manual maneuvering, a rear bumper, and an active tail light. The overall design of the off-road trailer enables towing cargo behind a snowmobile or off-road vehicle over rough terrain at higher rates of speed than conventional off-road towable trailers.
