Pivot-Offset Implement Mounting Assembly for Low-Friction Pushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional attachment systems for work implement mounting assemblies on vehicles face challenges such as increased friction due to force transfer to the ground, limited accessibility for installation, restricted upward pivoting, and inadequate load distribution, particularly in vehicles with insufficient ground clearance or space for underside-mounted configurations.
Innovation Solution
An attachment system comprising a vehicle attachment component with tri-directional fastening capabilities and a frame attachment component with a pivoting axis located below the vehicle's underside, allowing for improved longitudinal load pushing performance and easier alignment, while maintaining operation without the work implement assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the implement mounting assembly is front-mounted with the attachment point on the front portion of the vehicle, then the installation process is facilitated and upward pivoting range is improved, but horizontal pushing performance deteriorates due to increased friction
Solution Approach 1:
The patent introduces a vehicle attachment component as an intermediary element between the vehicle and the implement mounting assembly. This component includes a fastenable interface that attaches to the vehicle and an abuttable interface that engages with the implement mounting assembly, serving as a mediator that enables front-mounted attachment while improving force distribution to reduce friction during horizontal pushing operations.
2Force
If the implement mounting assembly is underside-mounted with the attachment point on the underside portion of the frame, then horizontal pushing performance is improved, but installation accessibility deteriorates and upward pivoting range is restricted
Solution Approach 1:
The patent positions the pivoting axis of the implement mounting assembly below the underside portion of the vehicle frame, utilizing the vertical dimension to create a lower pivoting point. This dimensional change allows the implement to pivot below the frame's lowermost point, increasing upward pivoting range while maintaining the force benefits of underside-mounted configurations for horizontal pushing operations.
3Force
If the pivoting axis is located above or at the level of the vehicle's underside, then upward pivoting range is limited by ground clearance constraints, but locating it below improves pushing performance
Solution Approach 1:
The patent inverts the conventional approach by positioning the pivoting axis below rather than above the vehicle's underside portion. This inversion allows the implement mounting assembly to pivot in an arc that extends below the frame's lowermost point, effectively increasing upward pivoting range without being constrained by the vehicle's ground clearance, while simultaneously improving longitudinal load pushing performance.

AI summary
An attachment system for attaching an implement mounting assembly to a vehicle, the attachment system including a vehicle attachment component that is fastenable to a front portion of the frame of the vehicle, and a frame attachment component that is removably attachable to the vehicle attachment component on one end via a securing axis, and pivotably attachable to the implement assembly on another end about a pivoting axis. When fastened to the vehicle, the vehicle attachment component is located upward from the underside of the frame. When the frame attachment component is attached to the vehicle attachment component, the securing axis is located upward from the underside portion of the frame, and the pivoting axis is located downward therefrom.
