Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Backhoe loaders face inefficiencies in excavating operations due to the need for seat adjustments and limited 180° excavating arm rotation, leading to poor operation efficiency, restricted view, and inflexible operation.
Innovation Solution
A backhoe loader design with a 360° rotating control platform and a 180° rotating excavating device, allowing for 360° excavating and bidirectional driving capabilities, along with a compact and stable structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the excavating arm rotates only 180°, then the structure remains simple, but the operation range is limited and rotating is inflexible
Solution Approach 1:
The backhoe loader is divided into two independent rotating systems: the control platform that rotates 360° relative to the vehicle body, and the excavating device that rotates 180° relative to the cab. This segmentation allows each component to have optimized rotation angles, expanding the overall operation range while maintaining structural simplicity of individual components.
Solution Approach 2:
The patent implements dynamic rotation capabilities where the control platform can rotate 360° to face any direction, and the excavating device can rotate 180° relative to the cab orientation. This dynamic adaptability allows the excavating arm to reach positions that would be impossible with a fixed 180° limitation, significantly expanding the operation range without requiring excessive structural complexity.
2Adaptability or versatility
If the seat rotates back and forth for loading and excavating operations, then the vehicle can perform both functions, but the operating procedure becomes tedious and time-consuming
Solution Approach 1:
The control platform is designed to rotate 360° relative to the vehicle body, enabling it to dynamically reorient toward different working areas. During excavating operations, the platform rotates to face the excavating device, allowing the operator to remain seated while the entire control platform and cab assembly rotates into the correct orientation. This eliminates the need for the operator to physically adjust the seat back and forth, significantly reducing operation time and procedural complexity.
Solution Approach 2:
The system performs automatic reorientation through platform rotation rather than requiring manual seat adjustment by the operator. The control platform self-adjusts its orientation to match the required working direction, whether for loading or excavating operations, making the adaptation process automated and time-efficient.
3Ease of operation
If the seat does not rotate with the excavating arm, then the structure is simpler, but the operation field of view and sense of control are poor
Solution Approach 1:
The control platform rotates 360° relative to the vehicle body, and the cab is mounted on the rotating platform. When the excavating device operates, the entire control platform with the cab rotates to face the direction of the excavating arm, providing the operator with an optimal field of view and sense of control. This dynamic coupling between platform rotation and cab orientation enhances operational comfort and visibility without requiring the seat itself to rotate independently.
Solution Approach 2:
The patent merges the rotation function into the control platform level rather than requiring separate seat rotation. The cab and operator are carried along with the platform rotation, combining the orientation adjustment function at a higher system level. This approach provides the benefits of improved field of view and control sense while avoiding the complexity of independent seat rotation mechanisms.

AI summary
The backhoe loader includes: a vehicle body, including a first vehicle body and a second vehicle body which are connected sequentially; a loading device, arranged on the first vehicle body; a control platform, arranged on the second vehicle body and configured to rotate by 360° relative to the second vehicle body; a cab, arranged on a first side of the control platform; and an excavating device, arranged on a second side of the control platform opposite to the first side, the excavating device being configured to rotate by 180° relative to the cab. The backhoe loader can realize functions of 360° excavating and bidirectional driving. When the excavating device works, the backhoe loader can be directly moved by folding stabilizers and without changing the position of a seat back and forth, so that the excavating efficiency is improved.
