Onion Chopper Sweeper Mechanism for Residue-Free Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food choppers with narrow containers face difficulties in removing all chopped food items due to their design, making it hard to extract the chopped content efficiently.
Innovation Solution
An onion chopper design featuring a container with a blade tray and a pivoting lid, incorporating a sweeper mechanism that can be inserted between the opposing sidewalls to facilitate easy removal of chopped food, with the sweeper's width being less than or equal to the container's width, allowing it to span and clear the contents effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a narrow container is used for chopping food, then the device footprint is reduced, but it becomes difficult to remove all chopped food items from the container
Solution Approach 1:
The container is divided into two functional parts: the main chopping chamber and a removable blade tray. This segmentation allows the blade tray to be extracted for easy cleaning and food removal, resolving the contradiction between maintaining a compact container footprint and enabling efficient food removal.
Solution Approach 2:
The blade tray containing the cutting blades is designed to be removable from the container. This extraction mechanism allows users to easily remove chopped food by taking out the blade tray, eliminating the difficulty of scraping food from narrow container corners while maintaining a compact overall device size.
2Productivity
If a traditional blade design is used, then the chopping function is achieved, but food residues remain in the container after chopping
Solution Approach 1:
The blade tray is designed as a removable component that can be easily extracted from the container. This allows users to remove all chopped food by taking out the entire blade tray, eliminating food residues that would otherwise remain stuck in the narrow container corners, thus improving both productivity and reducing food loss.
Solution Approach 2:
The removable blade tray acts as an intermediary between the chopping operation and food removal. It serves as a transfer medium that holds all chopped food, making it easy to completely remove the food product without leaving residues in the container.

AI summary
An onion chopper includes container, a blade tray, and pivoting lid. The blade tray is removably mounted on an upper rim of the container and includes a sweeper positioned at one end of the blade tray. The sweeper is dimensioned to fit within the sidewalls forming the container to be used to clear chopped food bits from the container after they are cut by the grid of blades.
