Rotating Beaker Bowl Assembly for Simpler Micro Puree Drives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current micro puree machines for making frozen foods and desserts are inefficient and impractical for preparing non-dessert food products due to complex internal drive mechanisms and the need for both position and drive motor subassemblies to move synchronously, which complicates the process and increases user effort and time.
Innovation Solution
A micro puree machine with a spinning bowl assembly that includes a beaker coupling operatively coupled to a rotation motor subassembly, allowing the beaker to rotate independently while the mixing blade remains stationary, secured by a bayonet structure on the machine's base, preventing the beaker from rotating relative to the bowl coupling and simplifying the internal mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both position motor subassembly and drive motor subassembly are used to move the blade up and down and rotate it, then the blade can perform mixing and plunging functions, but the internal drive mechanisms become complicated and user effort and time increase
Solution Approach 1:
The mixing function is separated from the plunging function. The stationary blade performs mixing while the rotating beaker performs plunging, eliminating the need for a position motor subassembly and simplifying the drive mechanism to only require rotation capability.
Solution Approach 2:
Instead of moving the blade up and down to achieve plunging, the invention inverts the approach by rotating the beaker containing the ingredients. This relative motion between the stationary blade and rotating beaker achieves the same plunging effect with simpler mechanics.
2Reliability
If the drive motor subassembly moves up and down with the position motor subassembly, then the blade can be positioned correctly, but the internal drive mechanisms are complicated
Solution Approach 1:
The position control function is extracted from the drive mechanism. The blade is made stationary and fixed in position, eliminating the need for the drive motor subassembly to move up and down, thereby simplifying the internal mechanisms while maintaining reliable positioning.
3Manufacturing precision
If alignment structures are added to prevent beaker rotation relative to beaker coupling, then mixing precision is improved, but device complexity increases
Solution Approach 1:
Rectangular alignment structures with complementary shapes are used between the beaker bottom and beaker coupling upper surface. These asymmetric features prevent rotational misalignment through geometric constraints, ensuring precise mixing without requiring complex mechanical locking mechanisms.

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.
