Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing revolving and rotating stirrers struggle to effectively disperse nanoparticle-sized objects due to agglomeration, and planetary mixers, while effective, are inefficient and costly for small quantities.
Innovation Solution
A container with a crushing unit featuring a supporting member and crushing pieces that extend outwardly from the inner lid, non-rotatably fixed to the bottom surface, which crushes and disperses nanoparticle-sized objects without agglomeration, enhancing mixing force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a revolving and rotating stirrer uses only centrifugal force to stir nanoparticle-sized objects, then the structure is simple and easy to operate, but the objects tend to agglomerate and dispersion is not achieved well
Solution Approach 1:
The stirring function is segmented into two distinct components: the revolving container providing centrifugal force and the stationary crushing unit with multiple crushing pieces. This segmentation allows each component to specialize - the container handles bulk movement while the crushing pieces handle particle breakdown, resolving the contradiction between structural simplicity and dispersion effectiveness
Solution Approach 2:
The crushing unit acts as an intermediary element between the centrifugal force and the nanoparticle-sized objects. It translates the rotational motion into crushing and dispersing action through its stationary crushing pieces, enabling effective nanoparticle handling while maintaining the simplicity of the revolving stirrer structure
2Reliability
If a planetary mixer is used to stir nanoparticle-sized objects, then dispersion is achieved effectively, but stirring time increases significantly and workability decreases
Solution Approach 1:
The stationary crushing pieces are pre-positioned to immediately crush and disperse particles as they enter the container, before the revolving action begins. This preliminary crushing action eliminates agglomeration at the source, achieving effective dispersion without requiring extended stirring time
Solution Approach 2:
The crushing unit rapidly processes particles through immediate crushing and dispersion action, skipping the prolonged stirring phase required by planetary mixers. The centrifugal force quickly distributes the crushed particles throughout the container, achieving dispersion in a fraction of the time
3Reliability
If a planetary mixer is used for small quantities of objects, then dispersion is effective, but the cost becomes prohibitively high
Solution Approach 1:
The invention replaces the expensive planetary mixer mechanism with a simple stationary crushing unit that can be easily manufactured. The crushing pieces are simple geometric elements that can be produced at low cost, making nanoparticle dispersion economically viable for small quantities
Solution Approach 2:
The complex planetary mixing mechanism is extracted and replaced with only the essential crushing function. By taking out the unnecessary revolving and rotating components and keeping only the stationary crushing unit, the system achieves dispersion effectiveness at a fraction of the cost

AI summary
The present invention relates to a container for a stirrer used in a stirrer stirring objects through a centrifugal force. The container for the stirrer includes a container body of which the top is opened and in which a receiving space is formed, an outer lid coupled to the top of the container body, and a crushing unit including a supporting member disposed in the receiving space, and a crushing member extending outward from the supporting member and crushing and stirring the objects received in the receiving space. Thus, nanoparticle-sized objects can be rapidly crushed and stirred without agglomeration.
