Solution Overview

Problem

Existing all-terrain trailers lack a design that allows for easy conversion between a hauling trailer and a storage basket, with removable wheels and axle storage, making them inefficient for use as a storage container when not in use and requiring specialized tools for configuration changes.

Innovation Solution

A rectangular basket trailer with removable wheels and axle storage, capable of being secured to an ATV or snowmobile as a storage basket when not in use, featuring a false bottom for flat surface hauling and easy conversion to a towed trailer with removable components for stowed storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the trailer is designed with removable wheels and axle storage for conversion between trailer and storage basket modes, then the adaptability and versatility are improved, but the device complexity increases

Engineering Contradiction:
Improveconversion capabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The trailer is divided into modular components including removable wheels, separate axle storage compartments, and detachable baskets that can be independently assembled or stored, enabling easy conversion between configurations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The same structural components serve multiple functions: the basket serves as both a storage container and a trailer body, the axle storage compartment doubles as structural support, and the removable wheels enable both trailer mode and pure storage basket mode operation

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If the trailer is designed to be lightweight and collapsible for easy transport over uneven terrain, then the ease of operation is improved, but the strength and durability may be compromised

Engineering Contradiction:
ImprovemanipulabilityVSAvoidstructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The trailer incorporates collapsible side walls and adjustable components that can be dynamically reconfigured between a compact stowed state for easy transport and an expanded operational state for maximum strength and utility

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the trailer is designed with a false bottom to cover the tire storage compartment, then the ease of operation is improved by enabling flat surface hauling, but the device complexity increases

Engineering Contradiction:
Improvehauling capabilityVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The false bottom is designed as a removable panel that can be extracted to access the tire storage compartment below, allowing the compartment to serve dual purposes: structural support when covered and accessible storage when the panel is removed

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Provided is an all-terrain trailer for hauling large objects over uneven landscapes. The trailer is capable of carrying items within its volume in both its deployed and stowed state. Deployed, the trailer is a basket shaped body with a pair of wheels removably secured via a removable axle. The trailer is attached to the lead vehicle using a removable trailer hitch linkage that is secured to the basket body via fasteners. In a stowed state, the tires and axle are stored within a storage area in a lower portion of the basket body. In one embodiment, a false bottom is placed over the storage area, creating a flat trailer bed that objects can be laid upon. The basket body is removably secured to the hood of a lead vehicle, thereby providing a carrying basket while the vehicle is in transit.
