Collapsible ATV Trailer Assembly With Telescoping Wheelbase Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing open trailers designed for carrying ATVs are often too large, heavy, and not easily collapsible for storage, and they lack flexibility in accommodating vehicles with varying wheel bases and axle lengths.
Innovation Solution
A trailer design featuring telescoping axle and front hoop assemblies that can be easily disassembled, allowing dynamic configuration to fit ATVs of different sizes without operator intervention, using telescoping sliders and removable ramps for easy loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a trailer is designed to be larger and stronger to carry bigger vehicles, then it can accommodate more vehicle types, but it becomes too heavy and expensive for carrying smaller vehicles like ATVs
Solution Approach 1:
The trailer is divided into modular components including telescoping axle assemblies, removable ramps, and adjustable hoop structures. This segmentation allows the trailer to be reconfigured for different vehicle sizes and easily collapsed for storage, resolving the contradiction between versatility and weight by enabling a lightweight design that can adapt to various vehicle types through modular assembly rather than requiring a permanently heavy structure
Solution Approach 2:
The trailer incorporates dynamic elements such as telescoping axles that can extend or retract, and removable ramps that can be attached or detached as needed. These dynamic features allow the trailer to transform its configuration based on the vehicle being transported, achieving versatility without requiring a fixed heavy structure designed for the largest possible vehicle
2Weight of moving object
If a trailer is designed with fixed dimensions for a specific vehicle type, then it optimizes weight and cost for that vehicle, but it cannot accommodate vehicles with varying wheel bases and axle lengths
Solution Approach 1:
The telescoping axle assemblies allow the trailer to dynamically adjust its length to match the wheel base of different vehicles. The axles can extend or retract as needed, enabling a single lightweight trailer design to accommodate vehicles with varying axle lengths without requiring multiple fixed-size trailers
Solution Approach 2:
The trailer design incorporates universal features such as adjustable hoop assemblies and removable ramps that can be configured for different vehicle types. This multi-functionality allows a single lightweight trailer to serve multiple vehicle sizes and configurations, resolving the contradiction between optimized weight and adaptability
3Strength
If a trailer uses solid bed material for strength and durability, then it provides stable vehicle support, but it increases weight and prevents debris from falling through
Solution Approach 1:
The trailer bed utilizes a porous or open-grid structure instead of solid material. This porous design maintains sufficient strength for vehicle support while reducing weight and allowing debris to pass through, directly resolving the contradiction between strength and weight by eliminating unnecessary material while preserving structural integrity
4Strength
If a trailer is designed as a non-collapsible structure for durability, then it maintains structural integrity, but it occupies excessive storage space when not in use
Solution Approach 1:
The trailer is segmented into collapsible modular components including telescoping axles, removable ramps, and detachable hoop assemblies. These segments can be disassembled and collapsed into a compact configuration for storage while maintaining structural integrity during use, resolving the contradiction between durability and storage efficiency
Solution Approach 2:
The trailer incorporates dynamic collapsing mechanisms that allow the structure to transition between an expanded operational configuration with full structural integrity and a compact storage configuration. The telescoping axles and removable components enable this dynamic transformation, maintaining strength when needed while minimizing volume for storage

AI summary
An open trailer for carrying an all-terrain vehicle (ATV) has a front hoop assemble that is slidably connected to tongue assembly and a rear hoop assembly that that is fixedly connected to a proximal end of the tongue assembly. The rear hoop assembly comprises an axle to which are attached to tires and two ramps. When in use, the vehicle is driven up the ramps and onto the trailer until the front wheels of the vehicle are supported by the front hoop assembly. As the vehicle continues to be driven onto the trailer, the front wheels push the front hoop assembly toward a distal end of the tongue assembly until the rear wheel of the vehicle are supported by the rear hoop assembly.
