Vehicle Wheel Lifting Platform With Hoist And Barrier Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for lifting the wheels of small to medium-sized vehicles, such as snow blowers and lawn mowers, often require complex setup steps and may not efficiently secure the wheels, especially on uneven or soft surfaces.
Innovation Solution
A device comprising two platform assemblies with flat plates and side walls, attached to a horizontal support bar, which can be slid under the wheels and lifted using a hoist, with barrier rods to prevent wheel movement, allowing for easy and secure lifting of two parallel vehicle wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art devices use incline ramps for bracing and transporting wheels, then the wheels can be secured, but the setup steps become lengthy and complex
Solution Approach 1:
The device is divided into separate functional modules: a base assembly with flat plates for wheel contact, vertical walls for containment, and a lifting mechanism. This segmentation allows each component to be optimized independently and simplifies the overall setup process compared to integrated incline ramp designs.
Solution Approach 2:
The invention extracts the lifting function from the bracing function, separating them into distinct components. The flat plates and vertical walls handle bracing while a separate hoist mechanism handles lifting, eliminating the need for complex incline ramp structures that combine multiple functions.
2Reliability
If prior art devices use complex towing mechanisms, then wheels can be secured, but the setup becomes more lengthy and complex
Solution Approach 1:
The device is designed to be self-contained with an integrated hoist mechanism that automatically lifts the wheels once positioned on the flat plates. This eliminates the need for external towing equipment and reduces setup time by making the system self-sufficient.
Solution Approach 2:
The flat plates are pre-positioned on the base assembly ready to receive wheels, and the vertical walls are pre-assembled to provide immediate containment. This preliminary preparation eliminates time-consuming assembly steps during the actual wheel securing process.
3Ease of operation
If simple lifting mechanisms are used, then setup is easier, but wheel security on uneven surfaces may be insufficient
Solution Approach 1:
The vertical walls are positioned at specific locations around the wheel contact area to provide localized containment and security. This targeted approach ensures wheel security on uneven surfaces without requiring a complex overall structure, maintaining ease of operation while improving reliability.
Solution Approach 2:
The flat plates are designed with curved surfaces that conform to the contour of vehicle wheels, providing secure contact and stabilization on uneven surfaces. This curvature enhances wheel security while maintaining a simple, easy-to-set-up device structure.
