Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for cutting and peeling avocados and other fruits and vegetables lack the ability to adjust and secure the cutting assembly at desired angles, limiting versatility and efficiency in cutting, peeling, and slicing operations.
Innovation Solution
A device with a rotating blade assembly that can be adjusted and secured at various angles relative to a handle, utilizing a shaft or pin assembly for movement and positioning, allowing for different cutting configurations and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed cutting assembly is used, then the device structure is simple, but the cutting angle and positioning flexibility are limited
Solution Approach 1:
The cutting assembly is designed to be rotatable relative to the handle, allowing the cutting angle to be dynamically adjusted from a fixed position to multiple angular positions. The rotation mechanism enables the blade assembly to pivot around a central axis, transforming the static cutting angle into a variable parameter that can be adjusted during use.
Solution Approach 2:
The device is divided into distinct functional segments: the handle, the rotating blade assembly, and the cutting elements. This segmentation allows the blade assembly to be independently rotated and positioned without affecting the handle structure, providing flexibility in cutting angle while maintaining structural simplicity through modular design.
2Adaptability or versatility
If the blade assembly can be rotated to various angles, then cutting versatility is improved, but the complexity of securing and positioning the assembly increases
Solution Approach 1:
The blade assembly includes pre-positioned engagement features such as slots or notches that align with corresponding protrusions on the handle. These preliminary structural arrangements enable the assembly to be secured at specific angular positions without requiring complex locking mechanisms, as the geometry itself provides the positioning and securing function.
Solution Approach 2:
The rotating blade assembly incorporates self-securing features where the weight and geometry of the assembly itself provide the locking action. Once rotated to the desired angle, the assembly naturally engages with the handle structure through friction or mechanical interference, eliminating the need for additional securing devices or complex fastening mechanisms.
3Adaptability or versatility
If interchangeable blade assemblies are provided, then cutting capability is enhanced, but device complexity and number of components increase
Solution Approach 1:
A single handle unit is designed to accommodate multiple types of blade assemblies through a universal mounting interface. Different blade assemblies (e.g., slicing blades, peeling blades, dicing blades) can be attached to the same handle by rotating them into position and securing them using the same rotation and securing mechanism, allowing one handle to perform multiple cutting functions.
Solution Approach 2:
The interchangeable blade assemblies are designed with dynamic attachment and detachment capabilities. Each blade assembly can be quickly rotated into the operational position and secured, or removed and replaced with another blade type, enabling rapid switching between different cutting capabilities without permanently fixing a single blade type to the handle.

AI summary
A device for cutting, peeling and slicing avocados and other fruits and vegetables includes a handle, a frame element connected to the handle, and a rotating blade assembly operably secured to the frame. The rotating blade assembly has one or more cutting elements for cutting, slicing and peeling. The rotating blade assembly is operably secured to the frame by a shaft allowing both movement and positioning of the blade assembly at various angles in relation to the frame, and fixing the rotating blade assembly in a desired position for use.
