Removable multi-rasp assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-grater assemblies face difficulties in easy cleaning and safety due to inaccessible interior spaces and small gripping handles, which can lead to user injury during handling.
Innovation Solution
A multi-grater assembly with removable graters and a large gripping part that covers the unused grater, featuring a frustoconical shape with a C-shaped cross section and locking mechanism, allowing secure grip and easy assembly/disassembly without tools, along with a non-slip foot for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a multi-grater set forms a vertical container with a small handle, then the container structure is compact, but the handle provides insufficient grip support and exposes sharp graters to user injury
Solution Approach 1:
The handle is designed to receive and nest the first and second graters when not in use, concealing the sharp edges within the handle's internal cavity. This nesting arrangement provides both a large gripping surface for safe handling and protects users from exposed sharp graters.
2Productivity
If the multi-grater set forms a closed vertical container, then food preparation is efficient, but cleaning access to the interior is difficult
Solution Approach 1:
The grater assembly is divided into separable components - the first and second graters can be detached from the handle. This segmentation allows users to easily remove and clean each component individually, solving the cleaning accessibility problem while maintaining the container's food preparation efficiency when assembled.
3Stability of the object's composition
If the graters are fixed in the container, then the structure is stable, but disassembly for cleaning requires tools and is complex
Solution Approach 1:
The connection between the graters and handle employs a dynamic locking mechanism with movable locks that can be easily engaged and disengaged. The locks feature buttons or actuators that allow tool-free operation, enabling users to quickly assemble and disassemble the graters for cleaning while maintaining stable attachment during use.
