Food Processor Grinding Mechanism with Elastic Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motor-operated food processors lack an efficient and integrated grinding mechanism that can handle various food materials without the need for separate grinders, and existing grinders often produce noise and do not allow for precise control over grinding.
Innovation Solution
A food processor with a grinding element connected to the rotation element via a coupling element featuring a spring element, allowing for flexible movement to compensate for axial inclination and radial displacement, enabling gentle grinding with adjustable precision and reducing noise through sound-absorbing arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid coupling element is used to connect the grinding element to the rotation element, then the structural stability is improved, but the ability to compensate for axial inclination and radial displacement deteriorates
Solution Approach 1:
The coupling element is designed with elastic partial regions that allow dynamic adaptation. The spring element provides a range of movement both parallel to the rotation axis and perpendicular to it, enabling the grinding element to automatically adjust its position to compensate for axial inclination and radial displacement while maintaining stable operation during grinding.
2Manufacturing precision
If the grinding element is rigidly fixed to the rotation element, then the grinding precision is improved, but the dampening of shocks during crushing deteriorates
Solution Approach 1:
The coupling element incorporates elastic partial regions and spring elements that act as cushioning mechanisms before shocks are transmitted to the rotation element. These elastic components absorb and dampen the shocks that occur during the crushing of starting products, protecting the rotation element and motor from damage while maintaining grinding precision.
3Adaptability or versatility
If a separate grinder is used for grinding operations, then the grinding function is improved, but the device complexity and need for multiple accessories deteriorates
Solution Approach 1:
The grinding function is integrated into the food processor by connecting the grinding element to the rotation element through the flexible coupling element. This merging of functions allows the single device to perform both mixing and grinding operations, eliminating the need for separate grinders and reducing overall device complexity while maintaining versatile functionality.
