Food Processor Blade Assembly with Slidable Knob Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processors rely on press fit or friction fit to secure the blade assembly to the work bowl, which is not secure enough for easy and reliable operation.
Innovation Solution
A blade assembly with a top knob that is slidably movable to lock and unlock the blade to the work bowl, providing a secure locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If press fit or friction fit is used to secure the blade assembly to the work bowl, then the device structure remains simple, but the reliability of blade attachment is insufficient
Solution Approach 1:
The blade assembly incorporates a movable top knob that transitions between extended and retracted positions to dynamically change the locking state. When the knob is extended, it engages with the work bowl to lock the blade assembly securely. When retracted, it allows for easy removal. This dynamic mechanism provides reliable attachment without requiring complex permanent locking structures.
Solution Approach 2:
The top knob serves as an intermediary element between the blade assembly and the work bowl. It mediates the locking and unlocking functions by engaging with corresponding features on the work bowl when extended, providing secure attachment, and disengaging when retracted to allow removal. This intermediary component simplifies the overall locking mechanism while ensuring reliable blade attachment.
2Reliability
If a secure locking mechanism is implemented, then the operational reliability improves, but the ease of operation may be reduced
Solution Approach 1:
The movable top knob allows users to easily transition between locked and unlocked states by simply extending or retracting the knob. This dynamic design makes the blade assembly easy to install and remove while maintaining secure attachment during operation, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The locking function is segmented into a distinct top knob component that can be independently operated. This segmentation allows users to engage or disengage the locking mechanism without manipulating the entire blade assembly, significantly improving ease of operation while maintaining secure attachment when locked.
3Reliability
If a top knob locking mechanism is added, then the blade assembly security is enhanced, but the device complexity increases
Solution Approach 1:
The top knob locking mechanism is merged with the existing blade assembly structure, integrating the locking function into the blade assembly itself rather than adding a separate locking system. This integration enhances blade-to-bowl attachment security while minimizing the increase in overall device complexity by combining multiple functions into a unified structure.

AI summary
A blade assembly for a food processor is provided. The blade assembly includes a body, a top knob slidably movable relative to the body, and at least one blade fixed to the body. The knob is movable from a first position, in which the blade assembly is locked to the bowl of the food processor, to a second position, in which the blade assembly is unlocked from the bowl.
