Ground-Machining Machine with Adjustable Maneuvering Mast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground-machining machines, such as ground saws, do not allow for adjustable wheel height to accommodate different user builds, leading to inconvenience during operation.
Innovation Solution
A ground-machining machine design featuring a maneuvering mast with telescopic tubes and adjustable driving means, allowing the actuation means to be adjusted in height along a vertical axis, enabling the user to customize the handle and wheel height according to their build, while maintaining the ability to transition between idle and machining positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wheel height is fixed in prior art ground saws, then the structure is simple and robust, but the machine cannot be adapted to different user builds, reducing ease of operation
Solution Approach 1:
The maneuvering mast is designed with telescopic sections that allow dynamic adjustment of height. The mast can be extended or retracted to different lengths, enabling the wheel and handles to be positioned at various heights to suit different user builds, thus making the system adaptable rather than fixed
Solution Approach 2:
The height parameter of the maneuvering mast is made variable through the telescopic mechanism. By changing the extended length of the mast, the vertical position of the wheel and handles can be adjusted, allowing the same machine to accommodate users of different statures without requiring multiple different machines
2Adaptability or versatility
If the handles are made adjustable in prior art ground saws, then user adaptability is improved, but the wheel height remains fixed, creating inconsistency in ergonomics
Solution Approach 1:
The adjustment mechanisms for the handles and the wheel are merged into a single integrated system. By adjusting the telescopic maneuvering mast, both the handle height and wheel height are adjusted simultaneously, ensuring that both control elements remain at consistent relative positions and maintaining ergonomic integrity throughout the adjustment range
3Adaptability or versatility
If the maneuvering mast is made telescopic, then height adjustment is enabled, but the structural complexity and potential instability increase
Solution Approach 1:
The telescopic maneuvering mast employs a nested tube structure where one tube is inserted within another. This nested configuration allows the mast to extend and retract while maintaining a compact form when retracted. The concentric arrangement provides structural stability and allows for locking mechanisms that secure the mast at desired heights, preventing unintended movement during operation
