Food Processor Attachment with Manual Tool Release Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processing technologies face challenges in simplifying the coupling of processing tools to food processors, making it inconvenient, unreliable, and difficult to replace tools without requiring repair of the entire appliance.
Innovation Solution
A processing attachment with a rotatable counter-drive coupling that allows for easy and secure connection of processing tools, featuring a holding means that can be manually actuated to release tools, ensuring stable axial anti-slip protection and independent rotational coupling, thus enabling easy tool replacement without needing to repair the entire appliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a traditional coupling mechanism is used to connect processing tools to food processors, then the connection is secure and stable, but the tool replacement process becomes complex and requires repair-level intervention
Solution Approach 1:
The coupling mechanism is segmented into two independent parts: a drive coupling on the processing attachment and a counter-drive coupling on the processing tool. This segmentation allows the tool to be detached and replaced independently from the food processor, eliminating the need for complex repair-level intervention while maintaining secure connection during operation.
Solution Approach 2:
The holding means is extracted as a separate functional component that can be manually actuated to release the tool. This extraction enables simple tool replacement by allowing the user to disengage the holding means and remove the tool without affecting the entire food processor system.
2Ease of operation
If a secure coupling mechanism is implemented to ensure stable connection, then the processing tool remains firmly attached, but the ease of manual detachment is reduced
Solution Approach 1:
The holding means is designed as a dynamic component that can transition between a locked state (providing secure connection) and a released state (allowing easy detachment). The manual actuation mechanism enables the user to switch between these states, combining both secure attachment during operation and ease of detachment when needed.

AI summary
The processing attachment (1) has one or multiple drive counter couplings (6), which are rotatable about their own axis and are driven by a power source. A manually operated holding unit is provided on the processing attachment for one of the processing tools (2). The holding unit is moved between a holding position and a releasing position to either release or lock the processing tool relative to the processing attachment. An independent claim is included for a processing tool with a groove.
