Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ice cream makers with dual-motor systems are costly and bulky, limiting their market penetration due to high production costs and space requirements, making them less suitable for home users.
Innovation Solution
A single-motor system with a brushless direct current motor drives both the rotation and vertical movement of the cutter head using a single-axis design, incorporating a gearbox and lifting member to achieve uniform speed and motion, reducing the size and cost while maintaining functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dual-motor system is used to control cutter head rotation and vertical movement, then the stirring process is more precise and ice cream texture is finer, but the production cost increases and the machine size becomes larger
Solution Approach 1:
The patent combines two independent motor functions (rotation control and vertical movement control) into a single motor system. The brushless direct current motor drives both the cutter head rotation and the lifting mechanism through integrated transmission components, eliminating the need for separate motors while maintaining functional independence and control precision.
Solution Approach 2:
The single brushless direct current motor performs multiple functions: it controls both the rotational motion of the cutter head and the vertical lifting motion. The transmission system distributes this single motor's output to achieve both motion types, making the motor a universal drive for multiple functions.
2Manufacturing precision
If a dual-motor system is adopted, then the stirring control is more precise, but the market price of the machine increases
Solution Approach 1:
By merging the functions of two motors into one, the patent reduces the number of expensive components needed. The single brushless direct current motor with integrated transmission system lowers material costs, assembly costs, and maintenance costs compared to a dual-motor configuration.
Solution Approach 2:
The patent uses a cost-effective single motor solution instead of expensive dual motors, making the product more affordable for mass market consumption. This aligns with the nature of household appliances that require cost-effective designs for widespread adoption.
3Power
If dual motors are used, then the stirring function is more powerful, but the machine occupies more kitchen space
Solution Approach 1:
The patent consolidates two motor units into one compact brushless direct current motor with integrated transmission mechanisms. This merging reduces the overall volume of the motor assembly while maintaining the combined stirring power through efficient mechanical transmission to the cutter head.
