Dolly Assist Tool Leverage Mechanism for Heavy Load Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional dollies are difficult to use for lifting and transporting heavy or bulky objects, especially on uneven terrain and into vehicles, due to the need for manual lifting and the risk of injury from falling objects.
Innovation Solution
A T-shaped tool with a secure attachment mechanism to the dolly's base, featuring symmetrical handles and a long, straight body with a molded hook edge for easy attachment, reduces the effort required to lift and maneuver loaded dollies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional dollies are used to transport heavy objects, then the objects can be moved, but users struggle with lifting objects onto the dolly and transporting it up stairwells and over rough terrain
Solution Approach 1:
The patent introduces a dolly assist tool as an intermediary device that connects to the dolly and provides mechanical advantage. The tool includes a handle assembly and a engagement mechanism that attaches to the dolly, allowing users to leverage lever arms and pivot points to reduce the lifting force required to move the dolly and its load.
Solution Approach 2:
The assist tool is divided into functional segments: a handle portion for user input, an engagement mechanism that attaches to the dolly, and a lever arm that provides mechanical advantage. This segmentation allows each component to be optimized for its specific function while working together to reduce the overall lifting effort.
2Ease of operation
If traditional dollies are used, then objects can be transported, but there is difficulty with lifting loaded dollies in and out of vehicles and buildings
Solution Approach 1:
The assist tool serves as a mediator between the user and the heavy dolly load during loading and unloading operations. The engagement mechanism attaches to the dolly while the handle assembly provides a comfortable grip and leverage point, making the lifting of loaded dollies into vehicles and buildings significantly easier without requiring complex mechanical systems.
3Reliability
If manual lifting is used with traditional dollies, then no additional equipment is needed, but there is a risk of injury from falling objects
Solution Approach 1:
The assist tool acts as a safety intermediary by providing a secure attachment mechanism to the dolly and a comfortable handle assembly that allows users to maintain control during lifting operations. The engagement mechanism ensures the tool remains firmly attached to the dolly, preventing accidental detachment and reducing the risk of injury from falling objects.
