U-Shaped Feeding Device for Cutting Machine Carriage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting machines, especially those for domestic use, lack a safe and efficient mechanism for feeding vegetables like cucumbers or tomatoes to the cutting plane, making the process cumbersome.
Innovation Solution
A U-shaped feed device that attaches to the cutting machine's carriage, featuring a tubular feed channel with a non-circular cross-section and a recess for visibility, allowing angled feeding and stable attachment, enabling easy and safe feeding of vegetables to the cutting plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional residue holder is used on the cutting machine, then the structure is simple, but the feeding function is missing and vegetables cannot be safely fed to the cutting plane
Solution Approach 1:
The feeding device integrates multiple functions into a single attachment: it provides a feed channel for guiding vegetables, a U-shaped holding section for secure attachment to the carriage, and a support wall for stability. This multi-functional design enables the cutting machine to safely feed vegetables without requiring separate feeding tools or complex modifications.
2Stability of the object's composition
If the feed device is made wide for stable attachment, then the mounting stability is improved, but the storage space requirement increases and it cannot fit in standard kitchen drawers
Solution Approach 1:
The feeding device achieves stable mounting not by increasing width, but by utilizing the vertical dimension through a U-shaped holding section that embraces the carriage. The support wall extends downward to rest on the carriage surface, creating stability through vertical engagement rather than horizontal expansion. This allows the device to remain compact in width while maintaining secure attachment.
3Ease of manufacture
If the feed channel has a circular cross-section, then the manufacturing is simple, but the material guidance and rotation prevention is insufficient
Solution Approach 1:
The feed channel cross-section is designed with non-uniform geometry: the lower region features two limbs converging at an angle less than 180° to guide material and prevent rotation, while the upper region maintains a simpler shape for ease of manufacture. This local variation in cross-sectional geometry provides enhanced material control where needed without significantly complicating the overall manufacturing process.
