Motorcycle Lift Device Single-Operator Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for loading and unloading motorcycles onto and off of trucks are inefficient, requiring multiple people and posing safety risks, especially when unloading, as they often rely on ramps and manual handling, which can be cumbersome and dangerous.
Innovation Solution
A self-propelled lift device comprising an under frame, main frame, carriage, pivot frame, and motorized shuttle that allows for safe and rapid movement of motorcycles between ground level and a truck bed, enabling single-person operation and secure fastening, with features like tie-down bars and damping devices for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a ramp is used to elevate the motorcycle, then the motorcycle can be moved to the cargo area, but multiple people are required to push the heavy cycle up the ramp
Solution Approach 1:
The patent replaces the manual mechanical pushing system with an automated motorized winch system. The winch mechanically pulls the motorcycle up the ramp, substituting human physical effort with motorized mechanical force, thereby reducing the number of people required from multiple to just one operator.
Solution Approach 2:
The lift device is designed to perform the loading function autonomously through motorized actuation. The system serves itself by using the winch mechanism to automatically elevate the motorcycle without requiring human physical intervention for the lifting action, freeing the operator to simply guide and secure the vehicle.
2Power
If a winch is used to pull the motorcycle up, then the heavy work is done automatically, but one person must hold the cycle upright and steer while another operates the winch
Solution Approach 1:
The patent integrates multiple functions into a single operator role. The operator both guides the motorcycle (holding it upright and steering) and operates the winch control, combining what were previously separate tasks into one universal operation. This is enabled by the simplified single-person control interface and the stable platform provided by the lift device.
3Ease of operation
If the cycle is ridden up the ramp, then a single cyclist can load the motorcycle, but riding it down backwards to unload is dangerous
Solution Approach 1:
The patent inverts the traditional loading/unloading approach. Instead of riding the motorcycle up and down the ramp, the system uses a motorized winch to pull the motorcycle up the ramp in reverse (backwards), and then lowers it safely under control. This inversion eliminates the dangerous backward riding maneuver while achieving the same loading function.
4Reliability
If proper securing of the cycle is performed, then the cycle is secured against swaying and falling, but the process is time consuming
Solution Approach 1:
The lift device performs preliminary positioning and stabilization of the motorcycle during the lifting process itself. The controlled ascent and descent, along with the stable platform provided by the lift, pre-position the motorcycle in a secure state before the operator begins the securing process, reducing the time and effort required for final securing operations.
