Tool Coupler Wedge Actuator Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool couplers require operators to exit the cabin multiple times to align and connect different tool systems to a machine, leading to inefficiencies and potential user errors due to obstructed views and misalignment issues.
Innovation Solution
A tool coupler system comprising a base with spaced-apart plates and an anchor with a monolithic structure, featuring primary and secondary engagement features and a wedge actuator, allowing for secure connection and alignment without the need for frequent operator exit, with the wedge actuator ensuring the pin is locked in place once aligned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operator manually aligns and connects the tool system using the prior art coupler, then the coupling can be completed, but the operator must exit the cabin multiple times which reduces efficiency and increases the risk of user error
Solution Approach 1:
The coupling system performs alignment and connection operations automatically without requiring continuous operator intervention. The base and anchor self-align through their geometric features (transverse slot with pin, wedge mechanism) and self-lock once engaged, eliminating the need for the operator to repeatedly exit the cabin to adjust alignment.
Solution Approach 2:
The base and anchor are pre-configured with specific geometric features (transverse slot orientation, wedge shape, engagement features) that automatically guide alignment during the coupling process. This preliminary configuration ensures proper alignment occurs automatically as components come together, eliminating the need for manual adjustment after exiting the cabin.
2Ease of operation
If the operator attempts to align the holes from inside the cabin, then operator safety and comfort are improved, but the obstructed view makes alignment difficult and increases the risk of misalignment
Solution Approach 1:
The patent replaces manual visual alignment with a mechanical alignment system. The transverse slot and pin configuration, combined with the wedge mechanism, automatically ensures precise alignment through mechanical constraints rather than relying on the operator's visual assessment from inside the cabin.
Solution Approach 2:
The wedge acts as an intermediary element that mediates the alignment between the base and anchor. As the wedge is actuated, it forces the transverse slot and pin into proper alignment, serving as a mechanical mediator that ensures precise positioning without requiring the operator to visually verify alignment.
3Adaptability or versatility
If the coupling mechanism requires manual alignment adjustments, then adaptability to misalignment is improved, but the complexity of the coupling process increases and time is lost
Solution Approach 1:
The coupling system transitions from a static manual adjustment process to a dynamic automatic alignment process. The wedge mechanism dynamically adjusts the position of the transverse slot relative to the pin during actuation, automatically compensating for any initial misalignment and achieving proper alignment without requiring multiple manual intervention cycles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces the number of times the operator needs to exit the cabin during coupling, enhances visibility and alignment, and increases operational efficiency by allowing for quick and secure connection of various tool systems to a machine.
Implementation Method 1
The anchor may further have a wedge, and a linear actuator disposed inside the pocket and connected to the wedge. The linear actuator may be configured to selectively push the wedge into the transverse slot over the first pin to inhibit removal of the first pin from the transverse slot.

AI summary
A tool coupler is disclosed for coupling a tool system to a machine. The tool coupler may including a base configured to connect to the tool system and having spaced-apart plates, hooks, a first pin, and at least one web connecting the spaced-apart plates. The tool coupler may also include an anchor configured to connect to the machine and having a monolithic structure. The anchor may also include a rounded primary engagement feature protruding outward to engage the hooks, a transverse slot formed within a top surface of the monolithic structure and configured to receive the first pin, and an elongated pocket formed inside the monolithic structure that is open to the transverse slot. The anchor may further include a wedge, and a linear actuator disposed inside the pocket and connected to push the wedge into the transverse slot over the first pin.
