Articulable Platform for Bulk Material Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manual wheeled carts are ineffective for transporting heavy loads around sites, especially in tight spaces and uneven terrain, while powered devices are often too expensive or impractical, leading to inefficient and costly solutions.
Innovation Solution
A self-contained mechanical platform mountable on a lawn tractor via a hitch-type mount, allowing for articulation and independent movement, with freely castering wheels and a foldable design for easy storage and adaptation to various loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual wheeled carts are used to transport heavy loads, then cost is reduced, but transport effectiveness and efficiency deteriorate
Solution Approach 1:
The patent introduces a platform as an intermediary between manual carts and powered devices. This platform can be attached to various power sources (lawn tractors, ATVs, bicycles, or manual effort) and provides a standardized interface for transporting bulk materials, thereby resolving the contradiction by offering a cost-effective solution that bridges the gap between inexpensive but ineffective manual carts and expensive but effective powered devices
2Productivity
If powered transport devices are used to move heavy loads, then transport efficiency is improved, but cost and practicality worsen
Solution Approach 1:
The patent applies dynamics by making the power source flexible and adaptable rather than fixed. The platform can be coupled to different power sources depending on the situation - powered sources for efficiency when needed, or manual sources for cost savings. This dynamic adaptability allows the system to achieve transport efficiency when required while avoiding the permanent cost burden of dedicated powered devices
3Weight of moving object
If wheeled carts are designed for heavy load capacity, then weight bearing ability is improved, but ease of manipulation deteriorates
Solution Approach 1:
The patent extracts the power source function from the transport platform itself. By separating the power source (whether powered or manual) from the platform, the system allows heavy loads to be carried without requiring the operator to manually manipulate heavy equipment. The power source provides the force for movement, while the platform simply carries the load, thereby resolving the contradiction between heavy load capacity and ease of manipulation
4Ease of operation
If standard hitch-type mounts are used for attachment, then ease of coupling is improved, but adaptability to different power sources deteriorates
Solution Approach 1:
The patent applies universality by designing the platform with a standardized hitch-type mount that can interface with multiple different power sources. The same platform can be attached to lawn tractors, ATVs, bicycles, or even used manually, making it universally adaptable while maintaining ease of coupling through the standardized interface

AI summary
A self-contained mechanical device is provided that is mountable to a lawn tractor or other similar powered unit, via a standard mounting system, such as a hitch-type mount, for movement of bulk material or heavy objects around a work site or storage facility. The device includes a casterable frame to which a manually or tiltable hopper is mounted. The device also includes a hinge system between the hopper and frame. A knuckle is provided as a connection point to facilitate storage in translation of the device from a substantially horizontal position to a substantially vertical position.
