Bucket Mixing Stand Structure for Torque-Resistant Viscous Material Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing stand devices for viscous building materials fail to securely hold bucket containers during power mixing, leading to torque-induced rotation and potential spills, especially with highly viscous materials like spackling compounds, posing safety hazards to workers.
Innovation Solution
A mixing stand device with a rigid frame assembly and base platform that securely positions a bucket container using inwardly tapered cylindrical configuration, upper and lower circular band members, and extended tabs to engage the bucket handle, preventing rotation and ensuring stability during mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If prior art mechanical retainer devices are used to provide adequate anti-rotational clamping, then torque resistance is improved, but worker safety deteriorates due to unsafe positioning requirements
Solution Approach 1:
The patent introduces a base platform as an intermediary element between the worker and the bucket container. The platform provides a stable standing surface positioned away from the mixing operation, allowing the worker to operate the powered mixing unit without standing over the bucket. This mediator eliminates the safety hazard while maintaining adequate torque resistance through the frame assembly's structural support.
2Productivity
If powered mixing unit is used to facilitate mixing of viscous material, then mixing effectiveness is improved, but bucket container stability deteriorates due to torque-induced rotation
Solution Approach 1:
The patent segments the support function into multiple independent components: the base platform provides stable grounding, the vertical posts provide height and positioning, and the circular band members provide circumferential clamping. This segmentation allows each component to specialize in resisting specific forces, with the combined system effectively counteracting torque-induced rotation while enabling effective powered mixing.
Solution Approach 2:
The patent applies local quality by positioning friction surfaces and clamping features at specific locations on the frame assembly. The circular band members are positioned to contact the bucket container at points optimized for resisting rotational torque, while the base platform provides localized stable support. This targeted placement of friction and clamping features maximizes torque resistance where needed most.

AI summary
A mixing stand device is disclosed for holding a conventional bucket container of a viscous building material in a proper stationary position for mixing. The present mixing stand device comprises a rigid frame assembly erected and attached upon a base platform in a position that allows a worker to stand upon the platform forward of the frame assembly. The frame assembly is formed having an inwardly tapered cylindrical configuration that is fitted to receive the bucket container, the frame assembly comprising upper and lower circular band members spaced apart and coaxially disposed at the respective top and bottom of the frame assembly with a plurality of leg members each being laterally disposed at 90° to the other and extending between the upper and lower band members. Leg members disposed on opposite sides of the frame assembly are formed having an extended tab projecting above the upper band member that align with and engage a pocket formed on either side of the bucket container for the working handle to prevent rotation of the container when seated within the frame assembly.
