Cutting disc and cutting device for chopping food products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices for chopping food products face challenges in achieving uniform and efficient chopping results, particularly in terms of consistency and smooth operation, due to the design of cutting elements and their interaction with food products during rotation.
Innovation Solution
The cutting disc features a combination of cutting elements with differently shaped cutting edges, arranged in a specific pattern to ensure that food products are chopped into either strip or slice form based on the direction of rotation, with centrifugal conveyance mechanisms to stabilize and guide the food product towards the outer edge, enhancing smooth operation and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cutting elements are arranged one behind the other with differently shaped cutting edges, then chopping uniformity and smooth operation are improved, but device complexity increases
Solution Approach 1:
The cutting disc is segmented into multiple cutting elements arranged in sequence around the circumference. Each cutting element is independently positioned to perform a specific chopping function, dividing the overall chopping task into discrete stages that improve uniformity while managing complexity through modular arrangement
Solution Approach 2:
Different cutting elements are given different local qualities through varying cutting edge shapes and orientations. Front cutting elements have specific edge geometries optimized for initial contact, while rear cutting elements have different geometries for finishing cuts, allowing each location to perform its specialized function for enhanced overall uniformity
2Manufacturing precision
If cutting elements have differently shaped cutting edges, then chopping consistency is improved, but manufacturing complexity increases
Solution Approach 1:
The cutting elements are designed as separable components that can be manufactured independently using standardized processes. This segmentation allows each element to be produced with precise geometries using conventional manufacturing methods, then assembled in the specific sequence required for consistent chopping performance
Solution Approach 2:
The cutting elements vary specific geometric parameters such as edge angle, curvature radius, and thickness to achieve different chopping effects. By systematically varying these parameters across the sequence of cutting elements, the patent achieves consistent chopping results while using manufacturable parameter ranges
3Ease of operation
If the cutting disc is designed to be detached from the shaft without tools, then ease of storage and transport is improved, but connection reliability may worsen
Solution Approach 1:
The connection system is segmented into detachable components with standardized interfaces. The cutting disc and shaft each have complementary connection elements that can be quickly engaged and disengaged without tools, while maintaining reliable torque transmission during operation through positive mechanical engagement
Solution Approach 2:
The connection mechanism is designed to be self-servicing, allowing users to attach and detach the cutting disc from the shaft without requiring external tools or specialized skills. The self-contained connection elements provide both ease of operation and sufficient reliability for the intended application
