Excavator Stick Coupling Interface for Skid Steer Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to effectively couple skid steer loader work tools to excavator machines, particularly at locations away from the machine's frame, due to a lack of a suitable interface for mounting these tools on the stick end of the excavator.
Innovation Solution
A novel interface system comprising a plate with engaging and coupling faces, brackets with aligned holes, and pins that connect to a coupling member attached to the machine's stick, allowing secure coupling of work tools to the excavator's stick end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If skid steer loader work tools are mounted on excavator machine frame, then work tools can be used on excavator, but mounting is difficult and not feasible at locations away from the frame
Solution Approach 1:
The interface assembly is divided into separate components: a plate with engaging face, brackets with holes, pins, and a coupling member. This segmentation allows the interface to be adapted to different work tools and mounting locations on the excavator, resolving the contradiction between versatility and ease of mounting.
Solution Approach 2:
The interface assembly is designed as a universal coupling mechanism that can accommodate various work tools (multi-purpose buckets, trenchers, etc.) at different locations on the excavator stick. The standardized plate, brackets, pins, and coupling member configuration enables the same interface to serve multiple functions and mounting positions, achieving both versatility and ease of operation.
2Adaptability or versatility
If a coupling interface is designed for stick end mounting, then work tool versatility is improved, but interface complexity increases
Solution Approach 1:
The interface is segmented into modular components (plate, brackets, pins, coupling member) that can be independently manufactured and assembled. This segmentation reduces overall complexity by allowing each component to be optimized separately while maintaining the complete coupling function.
Solution Approach 2:
The plate serves as an intermediary element between the work tool and the coupling member. The plate with its engaging face and brackets provides a standardized interface that simplifies the coupling process, acting as a mediator that reduces the complexity of directly coupling work tools to the stick end.

AI summary
An interface for coupling a work tool to a stick of a machine includes a plate having an engaging face and a coupling face. The engaging face of the plate is connected to the work tool. The interface also includes a first bracket and a second bracket positioned at a predefined distance from the first bracket. The first bracket and the second bracket extend from the coupling face of the plate and include at least one first hole and at least one second hole, respectively. The interface also includes a first pin received through the at least one first hole and the at least one second hole, and connected to a coupling member. The coupling member is connected to the stick of the machine and is configured to couple the work tool to the stick of the machine.
