Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an efficient and easy way to transport storage boxes and tools between a shop and a job site, particularly for single operators, as existing solutions are cumbersome and require assistance, leading to difficulties in managing and carrying heavy tools and equipment.
Innovation Solution
A single-operator multi-function foldable transporter with articulating legs and a motorized configuration, featuring a dual-threaded lead screw system for height adjustment and a loading ramp, which allows for easy loading and unloading onto a truck bed, and includes latch receivers for secure storage of boxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a traditional cart or dolly is used to transport storage boxes and tools, then it can carry heavy loads, but it requires two people to operate and is cumbersome to maneuver
Solution Approach 1:
The patent employs a mechanical advantage system with a 4:1 ratio pulley block and tackle, where the operator's pull on the rope is multiplied to generate sufficient lifting force to raise the entire cart and load. This counterweight mechanism enables a single operator to manage heavy loads that would otherwise require multiple people.
Solution Approach 2:
The patent replaces the traditional manual lifting and pushing mechanical system with a more efficient pulley block and tackle system. This mechanical substitution provides a 4:1 force multiplication ratio, allowing a single operator to easily raise and maneuver heavy loads that would be difficult to handle with conventional mechanical means.
2Weight of moving object
If a heavy-duty cart is used to carry tools and equipment, then it can support the weight, but it is difficult to lift onto a truck bed
Solution Approach 1:
The pulley block and tackle system acts as a mechanical counterweight mechanism, where the operator pulls on a rope that passes through the pulley system attached to the cart. This creates a mechanical advantage that reduces the effort needed to lift the heavy cart and its load onto the truck bed.
Solution Approach 2:
The patent replaces the direct lifting mechanical action with a pulley block and tackle system that provides force multiplication. This substitution transforms the difficult direct-lifting operation into an easier rope-pulling operation, enabling a single operator to load heavy equipment onto truck beds.
3Ease of operation
If a simple dolly is used for transportation, then it is easy to maneuver, but it cannot securely hold storage boxes and tools
Solution Approach 1:
The patent merges the maneuverability features of a simple dolly with the cargo-securing features of a heavy-duty cart. The resulting design incorporates both the ease of movement and the secure cargo-holding capabilities, eliminating the need to choose between the two extreme designs.
Solution Approach 2:
The cart is designed with multi-functionality to serve both as a maneuverable transport device and as a secure cargo-holding platform. The universal design includes features that enable easy maneuvering while simultaneously providing reliable cargo security through integrated storage box engagement mechanisms.
4Ease of operation
If a single-operator solution is designed, then operational simplicity is improved, but the structural complexity increases
Solution Approach 1:
The pulley block and tackle system, while adding mechanical complexity, enables single-operator capability by providing the necessary force multiplication. The added complexity is justified by the significant improvement in operational simplicity and the ability of one person to handle heavy loads.
Solution Approach 2:
The patent substitutes a more complex but efficient pulley block and tackle mechanical system for simpler direct-lifting mechanisms. This substitution increases mechanical complexity but achieves the goal of single-operator capability by providing superior force multiplication and control.

AI summary
A system is disclosed including a transporter, having a top load bearing surface or bed, and four wheeled articulating legs, that may be operated by a single user/operator, and can be lowered or raised by changing the lengths or angles of its legs while maintaining the transporter bed level. The legs that may be folded up to be loaded onto or unloaded from a truck bed, or a stationary platform, by a single operator while carrying heavy load. The loading and unloading process is assisted by various safety brakes that prevent accidental slippage of the transporter off the truck bed. The legs' angles are changed using a dual-threaded lead screw. The transporter further includes two edge detectors on the front-end and the rear-end to detect the edge of the truck bed automatically, and prepare the folding of the transporter legs for loading onto the truck bed.
