Solution Overview

Problem

Current micro puree machines for making frozen foods and desserts are inefficient due to complex internal drive mechanisms and require significant user effort, making them impractical for preparing non-dessert food products.

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, simplifying the internal mechanisms and reducing user effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If both a position motor subassembly and a separate drive motor subassembly are used to move and rotate the blade, then the machine can perform mixing and positioning functions, but the internal drive mechanisms become complicated

Engineering Contradiction:
Improvemixing and positioning functionVSAvoidinternal drive mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the position motor and drive motor functions into a single motor assembly. The motor assembly includes a motor body with a rotor that directly provides both rotational motion for mixing and axial motion for positioning the blade, eliminating the need for separate motor subassemblies and complex gear arrangements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single motor assembly is designed to perform multiple functions simultaneously. The rotor of the motor provides both rotational movement for ingredient mixing and axial movement for blade positioning, making one component serve multiple purposes that previously required separate dedicated mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If a complex internal drive mechanism is used to move and rotate the blade separately, then precise control of blade position and rotation is achieved, but user effort and operation difficulty increase

Engineering Contradiction:
Improveblade position controlVSAvoiduser effort
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The motor assembly automatically controls both blade rotation and positioning through its dual-motion capability. The system self-regulates the blade's axial position and rotational speed without requiring user intervention to adjust separate mechanisms, reducing operational complexity while maintaining precise control.

Inventive Principle:
Principle #25Self-service

3Productivity

If the beaker coupling and beaker rotate together with the blade, then mixing action is effective, but the alignment structures prevent independent rotation and add structural complexity

Engineering Contradiction:
Improvemixing effectivenessVSAvoidalignment structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system is divided into separate functional segments: the blade assembly that rotates for mixing, and the beaker coupling with alignment structures that remains stationary. This segmentation allows the blade to perform its mixing function independently while the beaker coupling provides structural support and alignment without participating in rotation, reducing unnecessary structural complexity.

Inventive Principle:
Principle #1Segmentation

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.
