Wire Fruit Corer and Slicer for Safe Strawberry Quartering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cutlery devices for removing the stem and core from fruits like strawberries are time-consuming and pose safety hazards due to the use of sharp knives, and they cannot efficiently slice the fruit into desired portions.
Innovation Solution
A child-safe, hand-operated fruit corer and slicer with a handle and two wire members, one with a triangular shape for coring and another with wing-like structures for slicing, allowing for efficient core removal and slicing into four equal pieces without the need for a knife.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a paring knife is used to remove the stem and core from strawberries, then the core removal task can be completed, but it is time consuming and presents a safety hazard due to the sharp edge
Solution Approach 1:
The patent replaces the traditional knife-based mechanical cutting system with a wire-based system. The wire members, when rotated, cut through the fruit core through rotational motion rather than linear knife movement, eliminating the need for sharp edges and improving safety while maintaining efficiency
Solution Approach 2:
The patent introduces rotational dynamics to the coring process. The handle rotates the wire members in a circular motion, allowing the wire to progressively cut through the core as it rotates, making the process faster and safer compared to static knife cutting
2Adaptability or versatility
If specialized hand devices are used to separate the outer meat from the stem and core, then the core removal can be achieved, but they cannot be used to slice the strawberry, requiring an additional knife
Solution Approach 1:
The patent designs a single device that performs both coring and slicing functions. The wire members are configured to first remove the core through rotation, then continue rotating to slice the strawberry into quarters, eliminating the need for separate tools and improving versatility
Solution Approach 2:
The patent combines the coring and slicing functions into a single integrated device. The same wire members and rotational mechanism that remove the core are used to subsequently slice the fruit, merging multiple operations into one unified tool
3Productivity
If a paring knife is used to slice strawberries, then the slicing task can be completed, but it increases the safety hazard and time consumption
Solution Approach 1:
The patent replaces the knife-based slicing mechanism with a wire-based rotational cutting system. The wire members, through rotation, slice the strawberry into quarters without requiring sharp edges, improving both safety and efficiency simultaneously

AI summary
A child-safe, hand, fruit corer and slicer includes: handle, a wire member having two ends and a configuration between these ends that is adapted to: (a) provide the outline of: (i) a triangular-shaped structure that has three corners and a base that is situated approximately perpendicular to the handle's centerline, and (ii) a wing-like structure that extends perpendicular to the handle's centerline from each of the corners of the base of the structure, (b) enable the triangular-shaped structure to penetrate a fruit that is to be cored and sliced, and by the at least 180 degree rotation of the handle to core out a core section of the fruit, and (c) enable this wing-like structure to penetrate and slice the fruit into two halves when the handle is moved forward along the handle's centerline.
