Pineapple Corer With Sliding Section Cutter for Safe Chunking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for separating flesh from the core and rind of fruits, such as pineapples, are cumbersome and dangerous to use, especially when trying to cut the extracted flesh into sections, as they require heavy lifting and precise dexterity to make controlled cuts.
Innovation Solution
A tool with a cylinder-shaped corer and a section cutter that includes an annular hub, rim, and spokes, allowing for easy sliding and cutting of the flesh into sections without the need for manual handling, using a section cutter that can be mounted on the corer to facilitate smooth and controlled sectioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the tool is used to extract flesh from pineapple using a helical cutter, then the flesh separation is efficient, but the extracted flesh is difficult to handle and section due to its slippery and unstable nature
Solution Approach 1:
The section cutter is nested within the corer structure, with the annular hub slidingly received on the corer body. This integration allows the sectioning function to be performed immediately after flesh extraction without removing the flesh from the tool, eliminating handling difficulties while maintaining extraction efficiency.
Solution Approach 2:
The tool combines multiple functions (extraction and sectioning) into a single integrated system. The section cutter with spokes and annular rim works in conjunction with the helical flesh cutter to provide both extraction and sectioning capabilities in one tool, eliminating the need to handle slippery flesh separately.
2Manufacturing precision
If multiple lengthwise cuts are made to create sections or chunks of flesh, then the desired dimensions are achieved, but the operation becomes time-consuming and potentially dangerous
Solution Approach 1:
The section cutter is designed to perform sectioning cuts automatically as the flesh is being extracted. The spokes of the section cutter make preliminary cuts during the extraction process, so that when the flesh is removed, it is already pre-sectioned into uniform portions, eliminating the need for multiple subsequent cutting operations.
Solution Approach 2:
The tool performs sectioning automatically during the extraction process itself. The rotating section cutter with multiple spokes automatically divides the flesh into sections as it rotates with the corer, making the sectioning function self-performing without requiring separate manual cutting operations.
3Ease of operation
If the user holds the flesh with one hand while cutting with the other, then control over the flesh is maintained, but the risk of accidents increases due to the slippery nature of the flesh
Solution Approach 1:
The tool performs both extraction and sectioning automatically without requiring the user to manually hold or manipulate the slippery flesh. The flesh remains secured on the corer during the entire process, and the section cutter automatically divides it, eliminating the need for two-handed manual control and reducing accident risk.
Solution Approach 2:
The sectioning cuts are made automatically during the extraction process before the flesh is removed from the tool. This preliminary sectioning occurs while the flesh is still securely positioned on the corer, eliminating the need for subsequent manual handling and cutting operations that would require the user to hold the slippery flesh.

AI summary
A tool (1) for separating flesh from a core and a rind of a fruit, in particular a pineapple, comprising: a corer (10) that, op opposite ends, is provided with a driving member (40) and a cutting edge (12); a flesh cutter (20) extending radially on the corer and having at least one cutting edge (22), wherein the shape of the flesh cutter is such that upon rotation it executes a helical movement with a predetermined pitch; a rind cutter (30), provided at an outer end of the flesh cutter and extending parallel to the corer, said rind cutter including a cutting edge (32). The tool further comprises a section cutter (60), including an annular hub (62) configured to be slidingly received on the corer, an annular rim (66), and one or more spokes (64) radiating from the hub and interconnecting the hub and the rim.
