Insertable Peeling Device for Multi-Function Kitchen Appliances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for peeling vegetables, fruits, and potatoes, especially with electric kitchen appliances, require additional space and are not as efficient as they could be, as they often involve separate devices or complex setups.
Innovation Solution
A peeling device designed to be used as an insert in a kitchen appliance, featuring a central opening for attachment to a drive shaft, a grater with interchangeable components, and protrusions for efficient peeling, allowing for easy and quick peeling by transmitting torque and facilitating the removal of peels into a container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate electric peeling appliance is used, then peeling function is provided, but additional kitchen space is required
Solution Approach 1:
The peeling device is merged with the food processor by integrating it as an insertable component that attaches to the drive shaft. The peeling device shares the food processor's motor, power source, and operational space, eliminating the need for a separate peeling appliance and thus saving kitchen space.
Solution Approach 2:
The food processor is designed to perform multiple functions including peeling, cutting, and mixing by accepting different inserts. The peeling device utilizes the universal drive shaft and motor system of the food processor, allowing one appliance to serve multiple culinary purposes without requiring additional dedicated devices.
2Device complexity
If manual peeling with a knife is used, then no additional device is needed, but peeling requires great effort and time
Solution Approach 1:
The manual mechanical action of rubbing produce against a grater is replaced by a mechanically driven system. The food processor's motor rotates the peeling device at controlled speeds, automating the peeling action and significantly increasing productivity while reducing user effort to simple insertion and removal of the device.
Solution Approach 2:
The peeling device incorporates variable speed control through different insertions into the drive shaft system. By selecting different positions on the drive shaft (first, second, or third insertions), the user can dynamically adjust the rotation speed to match different produce types and peeling requirements, optimizing both efficiency and effectiveness.
3Ease of manufacture
If a fixed grater design is used, then manufacturing is simple, but cleaning is difficult due to dirt accumulation
Solution Approach 1:
The grater is segmented from the frame, allowing it to be removed independently for cleaning. This segmentation enables the grating surface to be accessed and cleaned separately from the motor housing and other components, making maintenance easier while keeping the overall manufacturing process relatively simple.
Solution Approach 2:
The grater surface is coated with a non-stick coating that prevents dirt and food residue from adhering strongly. This coating makes the grater easier to clean by reducing the adhesion of contaminants, allowing for quick wiping or rinsing without requiring intensive scrubbing or disassembly.
4Device complexity
If the drive shaft is exposed, then simple structure is maintained, but safety risk increases from contact with produce
Solution Approach 1:
The drive shaft is nested within the peeling device structure. The peeling device encloses the drive shaft in its operational position, preventing direct contact between the rotating drive shaft and the produce or user's hands. This nesting approach maintains safety without requiring complex external guards or covers.
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
Enables efficient and space-saving peeling of various produce types by integrating with existing kitchen appliances, ensuring all areas are peeled and peels are effectively collected, enhancing user convenience and appliance compatibility.
Implementation Method 1
The cutting means transmits the torque via at least one adaptation interface or contact surface to the side of the peeling device facing the cutting means in the inserted state
Implementation Method 2
The grater comprises grating means arranged on a grating side of the grater, preferably in the form of sharp edges formed on the periphery of openings formed in the grater
Implementation Method 3
The mentioned protrusions (ribs) can be a one-piece component of the peeling device, which can optionally be formed in one piece
Implementation Method 4
The peeling device has a protrusion on its side facing the produce to be peeled, whereby the material is moved, in particular rotated, during the peeling process
Implementation Method 5
The peeling device can have multiple "protrusions", in particular two, three or any other number of protrusions. Even if there is a plurality of protrusions, they can be formed in a rib-like manner
