Vegetable Cutter Presser and Feeder for Safe, Clean Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vegetable cutting machines are not ergonomically designed, making them difficult to handle and maintain, and they lack effective safety features and efficient cleaning mechanisms.
Innovation Solution
The machine features a curvilinear presser with a removable shaft and a turning handle for comfortable operation, a hinged food feeder with a locking mechanism, a modified food feeder mouth to prevent food from falling onto the cutting disk, and integrated motion transmission components within the motor support to simplify assembly and reduce water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the presser is fixed and integrated into the machine structure, then the machine structure is simpler and more rigid, but the presser cannot be removed for thorough cleaning and maintenance
Solution Approach 1:
The presser is divided into separate components: the presser body, the cylindrical tube, and the plunging device. These segments can be detached from each other and from the machine, allowing each part to be cleaned separately and thoroughly, while still forming a complete functional assembly when needed.
Solution Approach 2:
The presser is designed with dynamic mounting features including a pivoting connection at one end and a removable shaft at the other end. This allows the presser to transition between fixed and movable states, enabling easy removal for cleaning while maintaining structural stability during operation.
2Ease of manufacture
If the handle is fixed in position, then the structure is simpler and more stable, but it does not follow the user's hand movement and reduces operational comfort
Solution Approach 1:
The handle is designed to rotate about an axis during operation, allowing it to follow the natural movement of the user's hand. This dynamic adjustment maintains operational comfort and control while keeping the handle structure relatively simple through the use of a rotational joint.
3Stability of the object's composition
If the food feeder is permanently attached to the base cover, then the assembly is more rigid and stable, but it cannot be easily disassembled for cleaning
Solution Approach 1:
The food feeder is designed as a separate, detachable component from the base cover. This segmentation allows the food feeder to be removed easily for cleaning while maintaining a stable and rigid connection when assembled for operation.
Solution Approach 2:
The connection between the food feeder and base cover uses hinging means with a shaft that allows for controlled movement and easy disassembly. This dynamic connection provides rigidity during use but enables quick separation for maintenance and cleaning.
4Productivity
If the cutting machine processes food continuously without interruption, then productivity is higher, but food may fall onto the middle of the cutting disk where adequate cutting cannot be guaranteed
Solution Approach 1:
The mouth of the food feeder is designed with a projecting area that extends over the turning axis. This preliminary structural arrangement guides food into the correct position before cutting begins, preventing food from falling onto the middle of the cutting disk and ensuring uniform cutting throughout continuous operation.

AI summary
The machine disclosed herein is a vegetable cutting machine. It includes a base that houses a motor which activates the drive shaft of the cutting disks; a cover that closes off the base and that houses a cutting disk; a food feeder part joined to the cover in a way that allows dismounting; a food feeder mouth; and a curvilinear presser with a cylindrical tube projecting therefrom which is housed inside the feeder mouth. The presser is dismountable as a result of removable shaft. The presser has a turning handle at the end opposite the folding end thereof. The machine also includes a blocking device between the food feeder and the cover. The machine further incorporates a single support for the motor and all of the driving and motion transmission components. Lastly, the presser incorporates a safety lever which activates the power supply switch of the motor.
