Solution Overview
Problem
Excavator buckets can only be mounted on articulated arms in a single orientation, limiting their versatility and adaptability for different applications.
Innovation Solution
A bracket system that allows reversible mounting of excavation buckets on couplers of articulated arms, featuring concavities and abutments designed to accommodate hinge shafts and blocking bars in two opposite configurations, enabling the bucket to be used in both standard and reversed orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-orientation mounting system is used, then the mounting structure is simple, but the bucket adaptability is limited
Solution Approach 1:
The mounting bracket is designed with multiple concavities (first and second rear concavities, first and second front concavities) that can accommodate hinge shafts in different orientations. This allows a single bracket design to serve multiple functions: mounting buckets in both standard and reversed orientations, thereby improving adaptability without requiring separate mounting systems for each orientation.
Solution Approach 2:
The bracket body is segmented into multiple functional zones with distinct concavities positioned at different locations and orientations. Each concavity is specifically designed to receive hinge shafts in particular orientations, allowing the bracket to handle multiple mounting configurations through spatial segmentation of its structure.
2Ease of operation
If reversible mounting is implemented, then operational flexibility is improved, but the mounting mechanism complexity increases
Solution Approach 1:
The bracket integrates multiple mounting functions into a single unified structure. By combining multiple concavities and abutments into one bracket body, the design achieves reversible mounting capability without requiring separate mechanisms for different orientations, thus improving ease of operation while controlling overall mechanism complexity.
Solution Approach 2:
The bracket is designed with symmetric or mirrored concavity arrangements that allow it to accommodate hinge shafts in both standard and reversed orientations. This inversion symmetry enables the same bracket structure to function in opposite configurations, providing mounting flexibility without requiring fundamentally different mechanisms for each orientation.
3Reliability
If multiple concavities and abutments are added, then mounting security is enhanced, but manufacturing complexity increases
Solution Approach 1:
The bracket employs asymmetric concavity and abutment arrangements optimized for specific mounting orientations. Each concavity and abutment is positioned and shaped to provide secure engagement for hinge shafts in particular orientations, enhancing mounting security through strategically placed asymmetric features rather than uniform symmetric designs.
Solution Approach 2:
Different regions of the bracket body have specialized local features: rear concavities for receiving hinge shafts in one orientation, front concavities for another orientation, and abutments for positioning blocking bars. This local quality approach ensures that each part of the bracket is optimized for its specific function, improving overall mounting security while allowing for modular manufacturing of distinct features.

AI summary
A bracket for mounting an excavation bucket on a coupler of an articulated arm. The bracket comprises a body extending in a plane and having a central portion. This bracket allows reversible mounting of the coupler of the excavation bucket by providing two pairs of adjacent concavities at a front and at a rear portion of the body which can alternately hold a corresponding pair of hinge shafts of a coupler in either orientation. Abutments at the front and at the rear are provided to further retain the coupler in the mounting bracket in either configuration. A bottom of the mounting bracket comprises notches that fit with corresponding portions of the bucket for improved securing of the bucket assembly on the mounting bracket.
