Pot-Shaped Sieve Component With Inner Cutting Edges for Food Comminution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen appliances with pot-shaped sieve parts lack efficient comminution capabilities due to the location and design of cutting edges, which often result in uneven processing and potential tearing of food items.
Innovation Solution
A kitchen appliance component featuring a pot-shaped sieve part with radially aligned cutting edges on the inside, injection molded for sharpness, and a collar-like pot casing with elongated recesses, allowing for efficient comminution by distributing cutting edges evenly to segment the pot base and facilitate material processing through strategically oriented passage openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cutting edges are placed on the outer surface of the sieve part, then manufacturing is simpler, but comminution efficiency is reduced and food tearing occurs
Solution Approach 1:
The patent inverts the conventional location of cutting edges by placing them on the inner surface of the sieve part rather than the outer surface. This inversion allows the cutting edges to directly interact with food particles as they are conveyed through the sieve, enabling effective comminution while maintaining manufacturing simplicity through injection molding of the cutting edges into the inner surface.
Solution Approach 2:
The patent applies local quality by providing cutting edges only at specific locations on the inner surface of the sieve part where food particles are conveyed. The cutting edges are strategically positioned to interact with particles during the conveying process, providing localized comminution functionality where it is most needed while keeping the rest of the sieve structure simple for manufacturing.
2Productivity
If cutting edges are added to the sieve part, then comminution capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the cutting function with the sieve structure by integrating cutting edges directly into the inner surface of the sieve part. This combination eliminates the need for separate cutting components, maintaining device simplicity while providing effective comminution capability through the unified sieve-cutter design.
Solution Approach 2:
The sieve part performs dual functions: conveying food particles through its perforated structure and comminuting them through integrated cutting edges on its inner surface. This self-service capability allows the single component to handle both transportation and processing tasks, reducing overall device complexity while improving productivity.
3Productivity
If cutting edges are placed radially on the inner surface, then particle comminution is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The patent replaces complex mechanical cutting systems with injection-molded cutting edges integrated into the sieve part. This substitution allows precise radial orientation of cutting edges to be achieved through molding techniques rather than post-manufacturing mechanical adjustments, reducing manufacturing precision requirements while maintaining effective particle comminution.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid and effective comminution of food materials by ensuring cutting edges interact with particles to generate outward force, conveying them through openings efficiently, thus improving processing speed and preventing tearing.
Implementation Method 1
a rotating tool attached to the coupling generates a radial force on the material being processed, forcing it through the recesses

AI summary
The invention relates to a component of a kitchen appliance with a coupling for attaching a tool and a pot-shaped sieve part with a pot bottom provided with through-openings and a pot casing surrounding the pot bottom in a collar-like manner, the sieve part having cutting edges on an inside which are essentially radial to an axis of a coupling are aligned. At least 10% of the passage openings have a diameter of at least 0.2 mm. A particularly effective comminution of material to be processed can be achieved by such a component.
