Chopper Accessory Splash Guard to Prevent Coupling Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chopper accessories for hand-held kitchen appliances often require systematic cleaning due to food particles reaching the coupling mechanism, making the cleaning process cumbersome and inefficient.
Innovation Solution
A chopper accessory design featuring a splash guard that covers the food processing space, preventing particles from reaching the coupling piece and allowing for easy detachment and separate cleaning, combined with a detachable coupling mechanism using frictional or form-fit connections for secure attachment and easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the coupling piece is made detachable for easy assembly and disassembly, then the ease of operation is improved, but food particles can reach the coupling mechanism requiring systematic cleaning
Solution Approach 1:
A splash guard is introduced as an intermediary component between the food processing space and the coupling piece. The splash guard prevents food particles from reaching the coupling mechanism while allowing the coupling piece to remain detachable for easy assembly and disassembly. This mediator protects the coupling mechanism from contamination without compromising the ease of operation.
2Ease of operation
If the splash guard is made detachable for easy cleaning, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The chopper accessory is divided into separable components: the coupling piece, the container, and the splash guard. This segmentation allows each component to be optimized independently - the splash guard can be detached for easy cleaning, while the coupling piece maintains its detachable connection for ease of assembly. The segmentation enables targeted cleaning of only the food-contact surfaces without requiring disassembly of the entire mechanism.
3Reliability
If the coupling piece is designed with clutch components and gearing for secure tool coupling, then the reliability is improved, but the difficulty of cleaning increases
Solution Approach 1:
The splash guard serves as a protective intermediary that shields the complex clutch components and gearing from food particle contamination. By positioning the splash guard between the food processing space and the coupling mechanism, food particles are prevented from entering the coupling piece, thereby maintaining the reliability of the clutch and gearing without requiring extensive cleaning of these sensitive components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates convenient and efficient food chopping by keeping the coupling mechanism clean, reducing the need for systematic cleaning and enhancing user experience by allowing dishwasher-safe components.
Implementation Method 1
the coupling piece and the container preferably secure the rotatable tool in an operation position
Implementation Method 2
by means for a form-fit connection (such as at least one snap-lock means and/or at least one bayonet joint)
Implementation Method 3
the splash guard thus at least partially delimits the processing space

AI summary
Disclosed is a chopper accessory 100 for or of a hand-held kitchen appliance 1. The chopper accessory comprises a coupling piece 10, a splash guard 20, a rotatable tool 30, and a container 40. The rotatable tool 30 is configured to be coupled, by means of the coupling piece 10, to a drive unit 200 of the kitchen appliance 1. The coupling piece 10 is detachably fixable to the container 40, so as to cap the container 40, with the rotatable tool 30 extending into the container 40. The splash guard is configured to be detachably attached to the coupling piece 10, so as to at least partially cover a food processing space S within the container 40.
