Shovel Automatic Bucket Alignment via Teaching Data Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction efficiency is hindered by the need to manually align and position the boom, arm, and bucket of a shovel to match the excavation or leveling direction, which is time-consuming and reduces productivity.
Innovation Solution
A shovel equipped with a processor and memory that controls the turning operation of the upper turning body to automatically align the bucket along a predetermined axis, allowing for autonomous operation based on teaching data set by the operator, enabling efficient alignment and operation without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual alignment and positioning of the boom, arm, and bucket is performed to match the excavation or leveling direction, then the shovel can perform construction operations, but the construction efficiency is hindered due to the time-consuming nature of manual alignment
Solution Approach 1:
The shovel system performs self-alignment through automatic control. The control unit automatically adjusts the boom, arm, and bucket positions based on stored teaching data, enabling the system to align itself without manual intervention. This self-service capability eliminates the time-consuming manual alignment process while maintaining construction operations.
Solution Approach 2:
The system stores teaching data in advance that contains the optimal positions and movements of the boom, arm, and bucket for various construction operations. By pre-storing this alignment information, the system can quickly retrieve and execute the correct alignment without performing manual adjustment during actual construction, thereby improving efficiency and reducing alignment time.
2Productivity
If automatic control is implemented to align the bucket along a predetermined axis, then work efficiency and productivity are improved, but the device complexity increases due to the addition of processor and control systems
Solution Approach 1:
The control unit serves multiple functions: it stores teaching data, processes alignment calculations, controls the boom, arm, and bucket movements, and manages the overall automatic operation. By consolidating these functions into a single multi-functional control system, the patent reduces overall system complexity compared to having separate dedicated components for each function.
Solution Approach 2:
The system uses teaching data that copies the optimal movement patterns and positions from manual operation demonstrations. Instead of requiring complex real-time calculations and sensors for every alignment decision, the system replicates proven alignment sequences from the teaching data, simplifying the control logic while maintaining high work efficiency.

AI summary
A shovel includes a traveling body, a turning body mounted on the traveling body, a work attachment including a boom attached to the turning body, an arm attached to an end of the boom, and an end attachment attached to an end of the arm, and a processor coupled to a memory storing instructions and configured to read and execute the instructions stored in the memory to control a turning operation of the turning body in accordance with a predetermined operation of the work attachment to cause the end attachment to perform the predetermined operation as seen in a plan view in response to an operation by an operator.
