Motorized Vehicle Bucket with Dual-Axis Rotation for Side Dumping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorized vehicles, such as power buggies, lack the capability to efficiently dump materials to the sides, limiting their operational flexibility in confined spaces and requiring manual handling for side dumping, which can be cumbersome and inefficient.
Innovation Solution
A motorized vehicle design featuring forward and rearward wheel assemblies with independently operable tires and a bucket assembly that can pivot and rotate to allow for side dumping, enabling the vehicle to discharge materials directly to either side, enhancing operational flexibility and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional power buggies with fixed forward-dump buckets are used, then the vehicle structure is simple and easy to operate, but the vehicle cannot efficiently dump materials to the sides, limiting operational flexibility in confined spaces
Solution Approach 1:
The bucket assembly is made dynamically configurable with two independent rotation degrees of freedom: rotation about a vertical axis and pivoting about a horizontal axis. This dynamic structure allows the bucket to be positioned in multiple orientations (forward, side, rearward dumping) rather than being fixed in a single forward-dump position, thereby enabling side dumping capability while maintaining operational flexibility
Solution Approach 2:
The bucket assembly is designed to perform multiple dumping functions (forward dumping, side dumping, rearward dumping) through its dual-rotation capability. The first rotation about the vertical axis and second pivoting about the horizontal axis enable the single bucket to serve multiple material discharge purposes, replacing what would traditionally require multiple specialized dumping mechanisms
2Adaptability or versatility
If the bucket assembly can rotate and pivot to dump materials to any angle, then operational flexibility is enhanced, but the vehicle structure becomes more complex
Solution Approach 1:
The bucket assembly incorporates two independent rotational degrees of freedom: rotation about a vertical axis and pivoting about a horizontal axis. This dynamic configuration allows the bucket to achieve any material discharge angle while using relatively simple rotational mechanisms rather than complex multi-component assemblies
Solution Approach 2:
The rotation mechanism is divided into two independent rotational movements: first rotation about a vertical axis and second pivoting about a horizontal axis. This segmentation of the rotation function into two independent degrees of freedom simplifies the overall mechanism design compared to attempting to achieve arbitrary angle discharge through a single complex mechanism
3Length of moving object
If the vehicle operates in confined spaces with narrow paths, then the vehicle can access restricted areas, but the vehicle requires wide stance for stability which may not be available
Solution Approach 1:
The wheel assemblies are configured to provide dynamic stability through their spacing arrangement. The forward wheel assemblies are spaced apart laterally, and the rearward wheel assembly spans the width of the vehicle, creating a stable polygonal support base that adapts to the vehicle's operational姿态, providing stability without requiring excessive vehicle width
4Stability of the object's composition
If forward wheel assemblies are spaced apart laterally, then the vehicle has wider stance for stability, but the vehicle width increases which may limit maneuverability in narrow paths
Solution Approach 1:
The wheel assembly configuration creates a dynamic stable base where forward wheels are spaced laterally and rearward wheels span the vehicle width. This arrangement provides stability through the polygonal support base formed by the wheel positions without requiring the vehicle to maintain a constantly wide stance, allowing better maneuverability in narrow paths while maintaining stability during operation

AI summary
A motorized vehicle is provided for transporting material and selectively dumping the material from the vehicle. In one example, the motorized vehicle includes a frame, first and second forward wheel assemblies coupled to the frame, and a rearward wheel assembly coupled to the frame. An engine is supported by the frame and configured to rotate the first and second forward wheel assemblies to move the motorized vehicle. The motorized vehicle also includes a bucket supported by the frame adjacent the first and second forward wheel assemblies. The bucket is configured to rotate about a vertical axis between a first radial positon in which a longitudinal axis of the bucket is generally parallel with the longitudinal axis of the frame and a second radial positon in which the longitude axis of the bucket is oriented generally perpendicular to the longitudinal axis of the frame.
