Dual-Blade Food Processor Assembly for Chopping and Pureeing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food processors face challenges in effectively processing difficult foods like ice and large items, as well as achieving thorough blending and pureeing, due to limitations in blade arrangements and rotation speeds.
Innovation Solution
A food processor blade assembly with a dual set of blades, including downwardly and upwardly angled blades, and substantially horizontal blades with rearwardly curved leading edges, positioned at different heights to create vertical circulation and enhance processing efficiency, along with a motor-driven processing apparatus that can rotate the blades at high speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single set of horizontal blades is used for chopping ice and large items, then chopping capability is improved, but blending and pureeing efficiency deteriorates
Solution Approach 1:
The blade assembly is segmented into two distinct sets: a first set of downwardly angled blades for pureeing and blending, and a second set of substantially horizontal blades for chopping ice and large items. Each set is optimized for its specific function, allowing the food processor to effectively perform both chopping and blending tasks without compromise.
2Device complexity
If blades are positioned at a single height, then device simplicity is improved, but processing thoroughness deteriorates
Solution Approach 1:
The invention transitions from a single-plane blade arrangement to a multi-level vertical arrangement. The first set of blades is positioned at a lower height while the second set is positioned at a higher height on the shaft. This vertical dimensionality ensures that food items at different heights within the processing container are effectively processed, improving thoroughness without excessive complexity.
3Productivity
If high rotation speed is used for chopping, then productivity is improved, but blending effectiveness deteriorates
Solution Approach 1:
The blade system is divided into functionally distinct sets positioned at different heights. The second set of horizontal blades operates optimally for high-speed chopping, while the first set of downwardly angled blades provides the mechanical action necessary for effective blending and pureeing. This segmentation allows each set to operate in its optimal performance range.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dual blade arrangement enables efficient chopping, pureeing, and vertical circulation of food, effectively processing both ice and large items by ensuring all food is processed by the puree blades, while the horizontal blades are used for chopping and creating a vortex, improving mixing and blending efficiency.
Implementation Method 1
The first, lower set of blades includes first and second blades, each blade having at least a portion angled downwardly relative to a horizontal plane
Implementation Method 2
The first, lower set of blades includes third and fourth blades, each blade having at least a portion angled upwardly relative to a horizontal plane
Implementation Method 3
The second, higher set of blades includes fifth and sixth blades, each of which is a substantially horizontal blade having a rearwardly curved leading cutting edge
Implementation Method 4
The dual blade arrangement enables efficient chopping, pureeing, and vertical circulation of food, effectively processing both ice and large items by ensuring all food is processed by the puree blades, while the horizontal blades are used for chopping and creating a vortex

AI summary
A food processor includes at least two different types of blades to process foods. A processing assembly includes a shaft, a set of pureeing blades attached to the shaft, and a set of substantially horizontal blades attached to the shaft. Each substantially horizontal blade may have a rearwardly curved leading cutting edge. The substantially horizontal blades are positioned higher with a food processing container than the pureeing blades. In some embodiments, upwardly angled blades may be included to induce vertical circulation and/or vorticial flow of the processed food.
