Ice Chopper Sieve Layout With Bottom Spindle Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food chopping devices with a sieve separating the processing and collecting zones are complex and costly due to the need for a bearing pin at the bottom, which restricts sieve design and material choice, especially when handling hard or large pieces.
Innovation Solution
A food chopping device with a bearing pin located at the bottom of the container allows for a simpler sieve design and material selection, enabling optimized shape and openings for efficient chopping, and reduces the need for torque-resistant materials, while allowing for modular integration with existing kitchen appliances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bearing pin is provided on the bottom of the sieve, then the sieve can support the chopping tool, but the sieve design becomes complex and material choice is restricted
Solution Approach 1:
The device is divided into two functional parts: the container bottom provides the bearing pin for structural support, while the sieve is a separate component optimized for chopping function with holes and specific geometry. This segmentation allows each part to be designed independently for its primary function.
Solution Approach 2:
The bearing pin function is extracted from the sieve and relocated to the container bottom. This removes the structural support requirement from the sieve design, allowing the sieve to be optimized purely for its chopping and separating function with appropriate holes and geometry.
2Ease of manufacture
If the bearing pin is provided on the bottom of the sieve, then the chopping tool can be mounted, but material choice and design flexibility are limited
Solution Approach 1:
Separating the mounting function (container bottom with bearing pin) from the processing function (sieve with holes) allows each component to be manufactured independently using optimal materials and methods for its specific requirements.
Solution Approach 2:
The container bottom is designed with local quality (bearing pin provision) for structural support, while the sieve has different local quality (holes and geometry) optimized for chopping. This allows each part to use materials and designs suited to its specific functional requirements.
3Strength
If the bearing pin is provided on the bottom of the sieve, then the chopping tool is supported, but torque and shear forces are not adequately resisted
Solution Approach 1:
The torque and shear force resistance function is extracted from the sieve and assigned to the container bottom structure. This allows the sieve to be designed with holes and optimized geometry for chopping, while the container bottom provides the necessary structural strength to resist forces from the rotating chopping tool.

Function Achieved in This Case
The solution simplifies the production and design of the chopping device, reduces material usage and costs, and enhances chopping efficiency by allowing for flexible sieve design and integration with existing appliances, while ensuring safety through quick stopping of the chopping tool.
Implementation Method 1
a chopping tool for reducing the food, said chopping tool being formed by a rotary cutting blade
Implementation Method 2
a sieve separating the processing zone from the collecting zone... every piece of food until it is small enough to fall through the sieve's openings
