Single-Actuator Multipurpose Bucket for Compact Loader Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Previously-used multipurpose buckets for heavy-equipment machines are too large and heavy, making them unsuitable for smaller machines like compact utility loaders due to the use of multiple hydraulic cylinders for actuation.
Innovation Solution
A multipurpose bucket design featuring a front and rear section rotatably coupled with a single actuator centrally positioned, allowing transition between closed and open positions, reducing the need for multiple actuators and enabling use on smaller machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple hydraulic cylinders are used to actuate the front and rear sections, then the bucket can transition between various configurations, but the bucket becomes large and heavy, making it unsuitable for smaller machines
Solution Approach 1:
The patent combines multiple actuation functions into a single hydraulic cylinder. The single actuator is positioned to simultaneously control the relative positioning between the front and rear sections, eliminating the need for separate cylinders on each lateral side. This merging of actuation mechanisms reduces the overall weight and component count while maintaining the bucket's ability to transition between digging, grapple, blade, and box blade configurations.
2Adaptability or versatility
If multiple hydraulic cylinders are positioned on each lateral side, then the bucket can operate in various configurations, but the device complexity increases
Solution Approach 1:
The patent merges multiple actuation systems into a single hydraulic cylinder with strategically positioned pivot points. The single actuator connects to both the front and rear sections through a coordinated linkage system, allowing one actuator to perform the work that previously required multiple actuators. This reduces mechanical complexity, fewer hydraulic connections, and simplified control while preserving all four operational configurations.
3Weight of moving object
If a single actuator is used to transition the bucket, then the bucket size and weight are reduced, but the actuator must be centrally positioned to achieve the same functionality
Solution Approach 1:
The patent employs asymmetric positioning of the single actuator along the longitudinal axis of the bucket, with the actuator mounted on one side rather than being centrally located. The actuator connects to the front and rear sections through an asymmetric linkage arrangement that provides the necessary mechanical advantage and range of motion. This asymmetric configuration simplifies mounting and maintenance while achieving the same functional results as a centrally positioned actuator.

AI summary
A multipurpopse bucket comprising a front section and a rear section rotatably coupled with the front section. As such, the bucket is configured to transition from a closed position to an open position. The bucket further comprises a single actuator configured to transition the bucket between the closed position and the open position. The actuator is centrally positioned with respect to a width of the bucket.
