Concrete Surface Machine Wheel Layout for Boom Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete surface treating machines with booms require time-consuming adjustments and stabilizations due to insufficient wheel support, especially when the arm is extended, necessitating removable and adjustable stabilizing feet.
Innovation Solution
A machine with orientable wheels and a central chassis, allowing the center of gravity to be positioned between the wheels, eliminating the need for stabilizing feet and enabling efficient maneuverability and stabilization without additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stabilizing feet are used to support the machine when the arm is extended, then the machine stability is improved, but the time required for positioning and stabilization increases
Solution Approach 1:
The patent removes the stabilizing feet from the machine structure entirely. Instead of having removable stabilizing feet that need to be adjusted and positioned, the machine uses its wheels to provide both mobility and stabilization. The hollow compartment design allows the arm to be retracted during transport, and the wheels alone suffice to support the machine in all operating conditions, eliminating the need for additional stabilizing components.
Solution Approach 2:
The wheels serve multiple functions: they provide mobility for moving the machine between treating locations and simultaneously provide stabilization support when the arm is extended. This multi-functional design eliminates the need for separate stabilizing feet, as the wheels are configured to bear the machine's weight and maintain stability in all operating positions.
2Stability of the object's composition
If removable and adjustable stabilizing feet are provided, then the machine can be stabilized in all circumstances, but the device complexity increases
Solution Approach 1:
The patent eliminates the complex system of removable and adjustable stabilizing feet entirely. The stabilization function is integrated into the wheel system, which is already necessary for machine mobility. This simplifies the overall device by removing unnecessary components and reducing the complexity of the stabilization system.
Solution Approach 2:
The patent combines the mobility function and stabilization function into a single wheel system. Instead of having separate wheels for movement and separate stabilizing feet for support, the same wheels perform both functions. This merging of functions reduces device complexity while maintaining or improving performance.
3Ease of operation
If the wheels are made orientable and adapted to support the machine, then the maneuverability is improved, but the device complexity increases
Solution Approach 1:
The orientable wheels serve multiple functions: they provide directional control for maneuverability and simultaneously adjust their orientation to support the machine's weight in various positions. The ability of the wheels to change orientation allows them to function both as mobility devices and as stabilization supports, eliminating the need for separate mechanisms.
Solution Approach 2:
The wheels are designed to be dynamically adjustable in orientation rather than fixed. This dynamic capability allows the wheels to adapt their position to support the machine when the arm is extended in different directions, while also enabling easy maneuverability. The dynamic adjustment is achieved through the wheel orientation mechanism that allows the wheels to pivot or rotate to appropriate angles.

AI summary
This invention relates to a treating machine (1) for a concrete surface comprising a treating tool (2) mechanically coupled to one end of a telescopic arm (3), a chassis (5) in which a compartment for the arm (3) is formed, and two axles (61, 62) attached at the level of two respective end segments (51, 52) of the chassis (5) each supporting at least one wheel (41, 42). The wheels (41, 42) are orientable and their arrangement via the above-mentioned axles (61, 62) and the chassis (5) is such that they allow the machine (1) to be supported regardless of the position of the tool (2) and the arm (3).
