Food Processor Eccentric Cutter Head Design for Turbulent Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processors have poor stirring performance due to regular shapes of the cutter head and cup body, leading to inadequate turbulent effects and inefficient food crushing.
Innovation Solution
A food processor design featuring a cup body with a non-eccentric structure and a cutter head with an eccentric contour, where the central axes of the cup body, cutter head, and cutter are positioned to create varying distances and angles, enhancing the turbulent effect and crushing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the cutter head and cup body have regular shapes with coincident central axes, then the structure is simple and easy to manufacture, but the turbulent effect and stirring performance are poor
Solution Approach 1:
The patent applies asymmetry by designing the cutter head with an eccentric contour where the central axis of the cup body does not coincide with the central axis of the cutter head. The cutter head contour line is positioned at a distance from the cup body central axis, creating an asymmetric configuration that generates turbulent flow during operation. This asymmetric design improves stirring performance while maintaining reasonable manufacturing complexity through standardized production methods for eccentric components.
2Device complexity
If the central axes of the cup body, cutter head, and cutter are coincident, then the device complexity is low, but the stirring performance and turbulent effect are insufficient
Solution Approach 1:
The patent implements asymmetry by deliberately offsetting the cutter head central axis from the cup body central axis. The cutter head contour line is positioned at a specific distance from the cup body central axis, creating an asymmetric arrangement that enhances turbulent mixing. This asymmetric configuration improves stirring efficiency and food processing performance while the overall device structure remains relatively simple and easy to manufacture.
