Bowl assembly for a micro puree machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current micro puree machines are complex due to the need for a separate drive motor subassembly to move the blade up and down, complicating internal drive mechanisms and increasing user effort and time in the ice cream making process.
Innovation Solution
A micro puree machine with a spinning bowl assembly where the beaker is securely attached to a rotation motor subassembly, allowing the beaker to rotate while the mixing blade remains stationary, simplifying the internal mechanisms and reducing user effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate drive motor subassembly is used to move the blade up and down, then the mixing function is achieved, but the device complexity increases and internal drive mechanisms are complicated
Solution Approach 1:
Instead of moving the blade up and down relative to a stationary bowl, the invention inverts the approach by keeping the blade stationary and rotating the entire bowl assembly. This reversal eliminates the need for complex vertical movement mechanisms while achieving the same mixing effect through relative motion between the blade and ingredients.
Solution Approach 2:
The invention merges the rotation function and position function into a single integrated bowl assembly that rotates on the drive shaft. This combines multiple functions (rotation and vertical positioning) into one mechanism, reducing the number of separate motor subassemblies and simplifying the overall drive system.
2Productivity
If the blade moves up and down with the position motor subassembly, then the mixing action is enhanced, but the internal drive mechanisms become more complex
Solution Approach 1:
The invention inverts the traditional approach by making the bowl rotate instead of the blade moving vertically. The stationary blade combined with rotating bowl creates effective mixing action through the relative motion and friction between the blade surface and ingredients, eliminating complex vertical drive mechanisms.
Solution Approach 2:
The rotating bowl assembly performs its own mixing function through rotation, eliminating the need for a separate position motor subassembly to move the blade. The system serves itself by using the rotation of the bowl to achieve both transport and mixing functions simultaneously.
3Device complexity
If a spinning bowl assembly is used, then the device complexity is reduced, but the alignment between beaker and blade must be precise
Solution Approach 1:
The invention uses asymmetric alignment structures including a square drive shaft and corresponding square recess in the bowl assembly, along with keyed connections and set screws. These asymmetric features provide precise mechanical alignment and prevent rotational misalignment between the beaker, bowl, and blade during operation.
Solution Approach 2:
The drive shaft acts as an intermediary element that transmits rotation from the motor to the bowl assembly while maintaining precise alignment. The keyed connection and set screws on the drive shaft serve as alignment mediators that ensure the beaker and blade remain properly positioned relative to each other during rotation.

AI summary
A bowl assembly for a micro puree machine includes a beaker removeably attachable to a beaker coupling located inside a bowl. The beaker coupling operatively couples to a drive motor assembly for rotation of the beaker coupling and the beaker relative to the bowl. The bowl in turn locks onto a bayonet structure on a base of the micro puree machine, which secures the bowl in position on the base while the beaker coupling and the beaker rotate.
