Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agitating/defoaming apparatuses face issues with high rotation and revolution speeds leading to excessive temperature increases and material degradation due to frictional and shearing forces, particularly with high-viscosity materials.
Innovation Solution
The apparatus includes a mechanism to adjust rotation speed independently of revolution speed, using a configuration with a container holder, revolution member, outer ring, and control unit to allow variable rotation speed adjustment, preventing temperature increases and material degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the revolution speed is increased to improve agitation action, then the agitation effectiveness is improved, but the rotation speed increases further causing excessive temperature rise and material deterioration
Solution Approach 1:
The invention makes the rotation speed variable and independent from revolution speed by introducing a separate drive system (second drive means) for the outer ring. This allows the system to dynamically adjust rotation speed based on material viscosity and processing requirements, rather than being locked into a fixed relationship where rotation speed increases with revolution speed.
Solution Approach 2:
The invention changes the operational parameters by allowing independent control of rotation speed and revolution speed. The control unit can set rotation speed to a low value even when revolution speed is high, preventing excessive temperature rise while maintaining effective agitation through the revolution motion.
2Productivity
If the rotation speed is increased to improve agitation action, then the agitation effectiveness is improved, but the frictional force causes material heat generation and deterioration
Solution Approach 1:
The invention makes the rotation speed variable and independent from revolution speed by introducing a separate drive system (second drive means) for the outer ring. This allows the system to dynamically adjust rotation speed based on material viscosity and processing requirements, rather than being locked into a fixed relationship where rotation speed increases with revolution speed.
Solution Approach 2:
The invention changes the operational parameters by allowing independent control of rotation speed and revolution speed. The control unit can set rotation speed to a low value even when revolution speed is high, preventing excessive temperature rise while maintaining effective agitation through the revolution motion.

If both rotation speed and revolution speed are increased, then the agitation action is improved, but the shearing force increases causing material transformation and deterioration
Solution Approach 1:
The invention makes the rotation speed variable and independent from revolution speed by introducing a separate drive system (second drive means) for the outer ring. This allows the system to dynamically adjust rotation speed based on material viscosity and processing requirements, rather than being locked into a fixed relationship where rotation speed increases with revolution speed.

AI summary
An agitating/defoaming apparatus adjusts a rotation speed and, even with respect to a material high in viscosity, prevents or reduces an increase in temperature of the material during agitating/defoaming. The agitating/defoaming apparatus includes a plurality of container holders, each holding a container. A revolution member supports each container holder so as to be rotatable, is provided in such a way as to be rotatable on a first rotational shaft, and causes each container holder to revolve around the first rotational shaft. A first drive rotationally drives the revolution member. A control unit performs drive control. An annular outer ring is arranged to surround the container holders in such a way as to be in abutting contact with an outer circumferential portion of each container holder. An outer ring rotation mechanism rotates the outer ring with a central axis of the outer ring set coincident with that of the revolution member.
