Rotating Snowplow Blade for Thin Hard Cheese Slicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cheese cutting devices are limited in cutting hard cheeses, as they tend to tear or crush rather than slice, failing to release aromas and provide an aesthetic presentation, especially when trying to cut very thin slices.
Innovation Solution
A rotating blade device with a curved, snow plow-like shape and a horizontal cutting edge, accompanied by a depth guide pad, designed to slice hard cheeses into thin, veil-like slices, allowing for enhanced aroma release and aesthetic presentation in conical spirals or pleating patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional wire or scraping blade is used to cut hard cheese, then the cheese can be cut into pieces or thick slices, but the cheese tears or crushes instead of producing thin, clean slices
Solution Approach 1:
The invention changes the critical parameter of blade geometry from traditional wire or scraping configurations to a specific curved snow plow shape with a horizontal leading edge. This geometric parameter change enables the blade to cut hard cheese at extremely thin thicknesses (millimeter or sub-millimeter scale) while maintaining structural integrity, producing clean slices without tearing or crushing that traditional methods cannot achieve.
Solution Approach 2:
The blade is designed with a curved snow plow shape rather than a straight or flat configuration. This curvature allows the blade to progressively engage and lift the cheese material before cutting, distributing the cutting force along the curved surface. The horizontal leading edge of the curve creates an optimal cutting angle that prevents cheese deformation, enabling precise thin slicing of hard cheese that maintains its structural strength.
2Reliability
If the cheese is cut into thin slices to enhance aroma release and aesthetics, then the presentation and aroma improve, but traditional cutting methods cause the cheese to tear or crush
Solution Approach 1:
By changing the blade geometry parameters to a curved snow plow shape with specific dimensions, the invention achieves slice thicknesses in the millimeter or sub-millimeter range that maximize surface area for aroma release. The precise geometric parameters ensure uniform slicing without tearing, simultaneously improving both aroma release effectiveness and slice uniformity, which traditional cutting methods cannot achieve together.
Solution Approach 2:
The curved blade geometry creates a progressive cutting action that lifts and separates cheese layers uniformly, producing consistent thin slices with smooth edges. This curvature ensures that each slice has uniform thickness and intact structure, maximizing the surface area available for aroma release while maintaining slice uniformity and preventing the tearing that would compromise both appearance and aroma effectiveness.
3Productivity
If a scraping action is used on hard cheese, then the cheese can be processed, but the aroma release and aesthetic presentation are insufficient compared to thin slicing
Solution Approach 1:
The curved snow plow blade shape transforms the cutting mechanism from a scraping action that destroys cheese structure to a lifting and slicing action that preserves integrity. The curvature allows the blade to engage the cheese surface, lift it slightly, and cut through in a single smooth motion, producing thin uniform slices that maintain structural strength. This enables efficient processing while maximizing aroma release through increased surface area, unlike scraping which compromises both efficiency and aroma effectiveness.

AI summary
The device has a hollow semi-cylinder shaped blade (2) with cylindrical ring at one of its ends to turn the blade around a shaft (1). The blade is curved in snowplow shape, and cut edge (6) of the blade is horizontal, and the blade is sharpened and edging. A base of the ring and a base of a handling rod are connected via a pad (7) at edges and round angles. The pad is fixed to the ring and the rod so as to be in front of the edge in a direction of rotation and parallel to the edge. The pad forms a guide for a depth of cut to permit flow of fine slices of structured cheese in a regular manner.
