Arcuate Food Processor Blade for Even Cutting Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processor cutting implements with flat or V-shaped blades result in uneven food processing due to gaps between blades, leading to inefficiency, increased energy consumption, and reduced service life.
Innovation Solution
A cutting implement with single-piece arcuate blades mounted on a rotatable blade axle, featuring an upper, middle, and lower blade section that interconnects, providing a continuous cutting edge and oblique cutting action, allowing for even processing and reduced energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If flat or V-shaped blades with gaps are used, then the structure is simple, but the food processing is uneven and efficiency is low
Solution Approach 1:
The patent applies curvature by designing the blade as an arcuate structure that follows the circular path of rotation. The blade includes an outer arcuate section, inner arcuate section, and intermediate section that collectively form a curved cutting surface. This curvature allows the blade to process food more evenly throughout the processing chamber, eliminating dead zones and improving overall processing efficiency without requiring multiple separate blade components.
Solution Approach 2:
The blade is segmented into multiple functional sections: outer arcuate section, inner arcuate section, and intermediate section. Each section serves a specific cutting function at different radial positions. This segmentation allows the single blade to perform multi-layer cutting operations simultaneously, addressing the efficiency problem while maintaining structural simplicity through integration rather than multiple separate blades.
2Area of stationary object
If multiple separate blades are used to improve coverage, then processing coverage increases, but the structure becomes more complex and gaps remain
Solution Approach 1:
The patent merges multiple cutting functions into a single integrated arcuate blade structure. The outer arcuate section, inner arcuate section, and intermediate section are combined into one continuous blade that rotates as a single unit. This merging eliminates the gaps and alignment issues between separate blades while maintaining comprehensive cutting coverage across the entire processing area.
Solution Approach 2:
The blade extends in multiple dimensions with outer and inner arcuate sections positioned at different radial distances from the rotation axis. This multi-dimensional arrangement allows the blade to engage food at various positions simultaneously during rotation, achieving comprehensive coverage without requiring multiple separate blade assemblies.
3Productivity
If higher rotational speed is used to improve cutting efficiency, then processing speed increases, but energy consumption increases and service life decreases
Solution Approach 1:
The arcuate blade design creates a multi-layer cutting effect where food is processed at multiple radial levels simultaneously during each rotation. This curvature-based design improves processing efficiency without requiring increased rotational speed, as the blade effectively processes more food per rotation cycle through its extended outer and inner arcuate sections.
Solution Approach 2:
The intermediate section of the blade provides continuous cutting action between the outer and inner arcuate sections. This ensures that the blade maintains effective contact with food throughout its entire rotational path, eliminating idle zones and ensuring continuous useful action at each rotation, thereby improving productivity without increasing speed or energy consumption.

AI summary
In a cutting implement for a food processor, a blade axle is rotatable on a rotation axis thereof in a direction of rotation of the blade axle. At least one blade assembly is mounted on the blade axle. The at least one blade assembly has at least one single-piece arcuate blade having an upper blade section coupled to the blade axle, a lower blade section separate from the upper blade section and coupled to the blade axle, and a middle blade section extending arcuately between and interconnecting the upper and lower blade sections. The single-piece arcuate blade has a leading edge in the direction of rotation of the blade axle, with the leading edge at least in part being configured to define a cutting edge of the single-piece arcuate blade.
