Bayonet-Lock Grater With Threaded Feed Disk for Constant Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional graters face issues with varying height due to filling levels, making storage in refrigerators challenging and risking exposure of food products during refilling, as well as limitations in handling larger portions and preventing accidental contact with the product.
Innovation Solution
A grater design featuring a cylindrical or conical container with a bayonet lock mechanism, a driver element with guiding elements, and a feed disk with segmented threads, allowing for constant height and secure, easy filling and grating of food products without exposure, using a retainer ring and end cap for containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the grater container is filled with larger portions of food products, then the grating capacity is improved, but the height varies and storage in refrigerator becomes difficult
Solution Approach 1:
The grater container is divided into a stationary base portion and a removable cover portion. The cover can be detached to allow filling of large food portions, then reattached to restore the compact constant height for refrigerator storage. This segmentation allows the container to adapt between two states: open for capacity and closed for compactness.
2Ease of operation
If the plunger is pulled out for refilling, then the filling operation becomes simple, but the product to be grated is exposed and risk of contact or pollution occurs
Solution Approach 1:
The filling operation is extracted from the main grater assembly by providing a separate removable cover that can be detached independently. This allows the user to fill the container through the opening created by removing the cover without pulling out the plunger, thus keeping the product enclosed and preventing exposure while maintaining easy filling access.
3Length of stationary object
If a threaded rod penetrates the grater container for constant height mechanism, then the total height remains constant, but the size of gratable food is limited
Solution Approach 1:
The threaded rod mechanism is extracted from the central interior space of the grater container and relocated to the base portion. This removal of the penetrating rod from the container interior eliminates the obstruction that limited food portion size, allowing larger quantities of food to be grated, while the constant height function is preserved through the removable cover design.

AI summary
A grater for grating of gratable food products with different hardness degrees. A cylindrical grater container receives a driver element which is mounted rotatively moveable and which includes a plurality of guiding elements, and which carries a feed disk at the same time. The feed disk has an external thread which is actively connected with an internal thread integrally formed on the inner surface of the grater container, and which can be linearly moved through the grater container by rotation of the driver element, and can be pressed onto a product to be grated which is located in the grater container, and the product to be grated can be grated by a grater insert attached on the grating side.
