Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material moving attachments face challenges in efficiently transitioning between forward and back-dragging operations, particularly in terms of visibility, material containment, and efficiency, especially when navigating obstacles.
Innovation Solution
A reconfigurable material moving attachment with a first and second frame that can pivot between retracted and deployed positions, allowing for optimized collection spaces and engagement angles tailored for both forward and back-dragging modes, enhancing visibility and reducing material spillage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the attachment uses a fixed single-frame structure for material collection, then the device complexity is low, but the adaptability between forward collection and back-dragging modes is insufficient
Solution Approach 1:
The attachment is divided into two separate frames: a first frame for forward collection operations and a second frame for back-dragging operations. Each frame is optimized for its specific function, allowing the attachment to adapt between different collection modes without requiring a completely reconfigurable single-frame structure.
Solution Approach 2:
The attachment incorporates a pivot mechanism that allows the second frame to be positioned in different configurations relative to the first frame. This dynamic repositioning capability enables the attachment to switch between forward collection and back-dragging modes by adjusting the angular orientation of the second frame.
2Reliability
If the attachment structure is extended to provide adequate containment walls for back-dragging mode, then the material containment is improved, but the visibility during operation deteriorates
Solution Approach 1:
The containment structure is segmented into two separate frames with their own containment walls. The second frame's containment wall provides material containment for back-dragging operations while the first frame remains in a retracted position, minimizing obstruction to the operator's view.
Solution Approach 2:
The attachment utilizes angular positioning in a different dimension to resolve the conflict. By rotating the second frame to specific angular positions during back-dragging operations, the containment wall can be oriented to provide material containment while maintaining adequate visibility for the operator.
3Productivity
If the attachment uses a single fixed collection space configuration, then the device complexity is low, but the productivity in transitioning between different collection modes is reduced
Solution Approach 1:
The collection space is segmented into two distinct configurations: a first collection space for forward operations and a second collection space for back-dragging operations. Each frame is pre-configured with appropriate containment walls and engagement edges optimized for its specific collection mode, enabling efficient transitions between modes.
Solution Approach 2:
The attachment is pre-configured with two distinct frames, each already optimized for its specific collection mode. The engagement edges and containment walls are pre-positioned to be immediately effective when the appropriate frame is activated, eliminating the need for reconfiguration during mode transitions.

AI summary
A material moving attachment for a vehicle includes a first frame and a second frame pivotable relative to the first frame about a pivot axis between retracted and deployed positions. The first and second frames include respective first and second containment walls extending laterally between left and right sides of the attachment. The first containment wall has a first vertical extent terminating at an abutment edge. The second containment wall has a second vertical extent bounded by spaced apart proximal and distal edges. In the retracted position, the first and second containment walls are disposed rearward of the pivot axis and in a vertically stacked arrangement with the proximal edge of the second containment wall bearing against the abutment edge of the first containment wall. In the deployed position, the second containment wall is disposed forward of the pivot axis and configured to engage a surface to be cleared.
