Rotatable Disk Knives for Frozen Confection Coating Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cutting mechanisms for frozen confection coatings face challenges such as mechanical stress on production lines, difficulty in applying multiple cut lines evenly around cylindrical products, and products getting stuck or breaking during the cutting process, especially when trying to create banana-style peeling effects with multiple flaps.
Innovation Solution
A coating cutting tool featuring disk-shaped side knives and an end knife, where the side knives are rotatable to facilitate cutting and can swing out of the way to prevent sticking, combined with a counterweight or spring mechanism to ensure continuous cutting and easy product removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cutting mechanisms are used to create multiple cut lines around cylindrical products, then cutting precision is improved, but mechanical stress on production lines increases and device complexity increases
Solution Approach 1:
The cutting tool is segmented into multiple independent disk-shaped knives (at least two knives) that can be positioned around the product void. Each knife operates independently to create cut lines at different locations, allowing multiple cut lines to be formed simultaneously without requiring a complex multi-axis mechanism. This segmentation enables precise cutting while maintaining relative simplicity in the overall device structure.
Solution Approach 2:
The invention transitions from conventional linear or planar cutting mechanisms to a three-dimensional arrangement where disk-shaped knives are positioned around the product void in a circular pattern. This spatial distribution in another dimension (radial arrangement around the product) allows multiple cut lines to be created efficiently while reducing the mechanical complexity compared to sequential linear cutting systems.
2Productivity
If products are moved through cutting mechanisms at high speed, then productivity is improved, but products may get stuck or break during the cutting process
Solution Approach 1:
The disk-shaped knives are designed to be rotatable about their axes when a product is introduced and retracted between the knives. This dynamic rotation allows the knives to adapt to the motion of the product, reducing the risk of products getting stuck or breaking during high-speed cutting operations. The rotational freedom provides a buffer that absorbs mechanical shocks and variations in product positioning.
Solution Approach 2:
The rotatable arrangement of the disk-shaped knives provides a cushioning effect before products can get stuck or break. The ability of the knives to rotate creates a buffer zone that prevents direct rigid contact between the cutting edges and the product, thereby cushioning against potential sticking or breaking events before they occur.
3Manufacturing precision
If multiple disk-shaped side knives are used for cutting, then cutting precision is improved, but the risk of products getting stuck between knives increases
Solution Approach 1:
The disk-shaped side knives are designed to be rotatable, which introduces a dynamic element that prevents products from getting stuck between the knives. As the product moves through the cutting mechanism, the rotatable knives can adjust their position slightly, preventing rigid jamming that would occur with fixed knives. This dynamic adjustment maintains cutting precision while reducing sticking.
Solution Approach 2:
The harmful effect of product sticking is extracted or removed from the system by allowing the knives to rotate. The rotation capability effectively separates the cutting function from the rigid structural constraint, enabling the knives to move independently to avoid product interference while maintaining their cutting function.

AI summary
The invention relates to a coating cutting tool for frozen confection comprising a frame defining a product void for receiving a product at least partly coated, a set of disk-shaped side knives comprising at least two knives mounted on the frame opposite of the product void, wherein the knives are rotatable arranged on the frame such that they can be rotated into a product coating cutting position for cutting the coating on the side of the product and out of such a position to a non-engaging position to allow the product to be moved passed the knives, and an end knife for cutting the coating on the end of the frozen confection. The invention also relates to a method for cutting a coating on a frozen confection.
