Foldable Food Processor Blade Assembly With Locking Knob
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processing devices lack ease of use and increased functionality, particularly in securely locking and storing blades for safety and cleaning purposes.
Innovation Solution
A blade assembly with a movable top knob that allows blades to be securely locked to the work bowl in an extended position and folded against the body when unlocked, featuring recesses for safe storage and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If blades are extended from the body for processing, then food processing functionality is improved, but blade exposure increases creating safety hazards and cleaning difficulty
Solution Approach 1:
The blade assembly incorporates a movable top knob that allows the blades to transition between extended and folded positions. This dynamic mechanism enables the blades to be extended during food processing for full functionality, then folded against the body for safety and cleaning, resolving the contradiction between operational versatility and safety hazards
2Productivity
If blades are extended for processing, then cutting performance is improved, but cleaning accessibility deteriorates
Solution Approach 1:
The movable top knob mechanism allows blades to be folded against the body during cleaning operations, providing easy accessibility to all blade surfaces for thorough cleaning. During food processing, the blades extend to their full cutting position to maintain optimal cutting performance, thus resolving the contradiction between cutting performance and cleaning accessibility
3Reliability
If a locking mechanism is added to secure the blade, then reliability is improved, but device complexity increases
Solution Approach 1:
The top knob mechanism serves dual functions: it acts as both the locking mechanism that secures the blade assembly to the food processor and the release mechanism that unlocks it for folding and cleaning. This self-service design eliminates the need for separate locking and releasing components, achieving reliable blade security while minimizing device complexity

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 a pair of processing blades pivotally connected 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 and the blades are extended from the body, to a second position, in which the blade assembly is unlocked from the bowl and the blades are folded up against the body.
