Three-Axis Carriage Assembly Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carriage assemblies in working machines, such as telehandlers, lack sufficient manoeuvrability, which hampers operator efficiency and stability when handling materials or cargo.
Innovation Solution
A carriage assembly with a first coupling body pivotally mounted to the working arm about a first axis, a second coupling body pivotally mounted to the first coupling body about a second axis perpendicular to the first axis, and a carriage pivotally mounted to the second coupling body about a third axis perpendicular to both, allowing for movement about three planes, enhancing versatility and stability by bringing the center of gravity closer to the end of the arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional carriage assembly is used with limited pivoting capability, then the structure is simpler, but the manoeuvrability and versatility are insufficient
Solution Approach 1:
The carriage assembly is divided into multiple coupling bodies (first coupling body, second coupling body) that can pivot independently about different axes. This segmentation allows each component to contribute to the overall manoeuvrability while maintaining a relatively simple individual structure, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The invention introduces pivoting about multiple perpendicular axes (first axis, second axis, third axis) rather than limited movement in a single plane. This dimensional expansion enables three-dimensional manoeuvring capability, significantly improving versatility while the modular coupling body design keeps the structural complexity manageable.
2Stability of the object's composition
If the carriage assembly is made more compact by repositioning components, then the center of gravity moves closer to the arm end improving stability, but the structural design becomes more complex
Solution Approach 1:
The recess in the second coupling body receives the extended portion of the first coupling body in a spatial arrangement that brings the center of gravity closer to the arm end. This three-dimensional spatial optimization achieves improved stability while the recess design itself is a relatively simple structural feature that doesn't significantly increase complexity.
