Solution Overview
Problem
Existing fruit cutting and peeling devices suffer from hygiene issues due to the difficulty in cleaning long and strong fibers, requiring laborious manual cleaning.
Innovation Solution
A cutting device with a detachable head element and cutting element connected by screw elements or bayonet locks, featuring a conical spreading surface and a linear drive unit, allowing easy disassembly and cleaning, and a peeling and coring device with a central ejection punch for efficient fruit processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cutting device uses a integrated design with fixed cutting elements, then the structural stability is improved, but the cleaning difficulty increases due to fiber adhesion on all surfaces
Solution Approach 1:
The cutting device is divided into separable components: a head element, a cutting element, and a connecting structure. The cutting element can be detached from the head element via the connecting structure (screw elements or bayonet locks), allowing the cutting element to be removed for easy cleaning without disassembling the entire device. This segmentation resolves the contradiction by enabling both structural stability during operation and ease of cleaning through component separation.
2Productivity
If the cutting element has a large surface area to effectively cut the pineapple, then the cutting efficiency is improved, but the fiber adhesion problem worsens
Solution Approach 1:
By making the cutting element detachable through the connecting structure, the large-surface cutting element can maintain its effective cutting area while being easily removable for cleaning. The segmentation allows the cutting element to perform its function efficiently during operation and be quickly cleaned afterward without fiber adhesion issues.
Solution Approach 2:
The cutting element is extracted as a separate, detachable component from the head element. This extraction allows the cutting element to be removed completely for cleaning, eliminating the fiber adhesion problem that would otherwise affect the large surface area used for efficient cutting.
3Reliability
If the connecting structure is made robust to ensure stable operation, then the operational reliability is improved, but the cleaning accessibility worsens
Solution Approach 1:
The connecting structure is designed as a separate, modular component that connects the head element and cutting element. This segmentation allows the connecting structure to be designed for robust operation (e.g., with screw elements or bayonet locks) while still being easily accessible for cleaning, as it can be detached with the cutting element or cleaned independently.
Solution Approach 2:
The connecting structure is extracted as a distinct component that can be removed or accessed separately. This extraction maintains operational reliability through robust connection mechanisms while improving cleaning accessibility by allowing the connecting structure to be cleaned independently or removed entirely.
4Ease of operation
If the cutting device uses manual operation without tool requirements, then the ease of operation is improved, but the disassembly capability for cleaning decreases
Solution Approach 1:
The connecting structure is designed with screw elements or bayonet locks that enable tool-free or simple manual disassembly. The screw elements can be unscrewed by hand, and the bayonet locks can be released with a simple rotational motion, allowing the cutting element to be detached for cleaning without requiring special tools while maintaining secure connection during operation.
Solution Approach 2:
The bayonet lock mechanism provides a dynamic connection that can be quickly engaged and disengaged through simple rotational motion. This dynamic connection maintains operational reliability during cutting while enabling easy manual disassembly for cleaning, resolving the contradiction between ease of operation and disassembly capability.
