Solution Overview

Problem

Conventional square graters are shaky and make it difficult to collect grated material efficiently, especially with moist goods like carrots, as they often require turning the grater upside down, which is not effective.

Innovation Solution

A square grater with a friction body featuring orthogonally aligned friction surfaces and a tubular container with a removable front wall that doubles as a slide, allowing for easy collection and emptying of grated material, along with a latching device for stability and non-slip materials for secure placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional square graters are used with fixed containers, then the structure is simple, but the grated material is difficult to collect and empty

Engineering Contradiction:
Improveease of collecting and emptying grated materialVSAvoidstructure complexity of container system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The container is divided into a removable front wall and a container body. The front wall can be separated from the container body to allow easy emptying of grated material, while the container body remains as a separate component that can be inserted into or removed from the friction body.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The removable front wall serves multiple functions: it acts as a closure for the container opening during grating, and when removed, it functions as a slide to facilitate complete emptying of grated material from the container body.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If the container is designed to be easily removed for emptying, then emptying becomes simple, but the stability during grating may be reduced

Engineering Contradiction:
Improveease of emptying containerVSAvoidstability of grater during grating process
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The container system transitions from a static fixed structure to a dynamic system where the front wall can be removed and the container body can be inserted or removed from the friction body. This dynamic design allows the system to adapt between stable grating operation and easy emptying as needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The removable front wall acts as an intermediary element that can be present during grating to maintain container integrity and absent during emptying to facilitate material removal. Its presence or absence mediates between the requirements for stability and ease of emptying.

Inventive Principle:
Principle #24Intermediary (Mediator)

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 design simplifies handling, ensures easy and residue-free collection of grated material, including moist goods, by allowing the front wall to be used as a slide for pushing out contents and providing a stable, ergonomic grip, enhancing user comfort and efficiency.

Implementation Method 1

The friction body has a circumferential border made of non-slip material on the longitudinal end, so that the friction body rests on a base via the border when in use

AI summary

The invention relates to a square grater (1) - with a grating body (20) with at least four grating surfaces (2a, 2b, 2c, 2d) aligned essentially orthogonally to one another for grating food to be grated, in particular foodstuffs such as cheese, fruit or vegetables. - With a container (3) for collecting the grated material, - wherein the friction body (20) has a tubular cross-section into which the container (3) can be inserted. It is essential to the invention that the container (3) has a removable front wall (6). This makes it easier to empty it.
