Fish Processing Support Web Groove for Knife Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fish processing, the existing L-shaped support bodies for conveying fish through cutting units with circular knives often result in unintentional contact between the support web and the knives due to wear and tear, leading to dull knives and decreased cutting quality, as well as potential machine damage.
Innovation Solution
The support web features a groove on its underside designed as a counter-position for the circular knives, allowing them to be positioned closer to the central bones and serving as a guide or counter-support, reducing the risk of contact and maintaining knife sharpness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the support web is positioned close to the circular knives to enable precise cutting near the central bone, then cutting precision is improved, but the risk of unintentional contact and knife dulling increases
Solution Approach 1:
The groove in the support web acts as an intermediary element between the support web and the circular knives. It provides a dedicated receptacle that guides the knives during operation, allowing them to pass through safely without direct contact with the support web itself, thus maintaining both cutting precision and knife sharpness
Solution Approach 2:
The groove is pre-formed in the support web at the correct position and dimensions before operation. This preliminary structuring ensures that when the circular knives pass through during fish processing, they automatically follow the predetermined path through the groove, preventing unintentional contact with surrounding areas
2Productivity
If the circular knives are positioned closer to the central bone to maximize yield, then productivity is improved, but the risk of contact with the support web increases
Solution Approach 1:
The groove serves as a protective intermediary structure that enables the circular knives to operate at optimal positions close to the central bone for maximum yield, while simultaneously protecting against harmful mechanical contact by providing a controlled passage through the support web
Solution Approach 2:
The groove structure provides beforehand protection by creating a safe zone that prevents direct mechanical contact between the support web and circular knives. This prior cushioning measure eliminates the risk of knife dulling and support web damage before such harmful contact can occur
3Ease of manufacture
If the support web structure is simplified to reduce complexity, then ease of manufacture is improved, but the ability to guide and protect the knives may be compromised
Solution Approach 1:
The support web is segmented by introducing the groove feature, which divides the solid structure into regions separated by the recess. This segmentation creates the necessary guidance function without requiring complex additional components, maintaining ease of manufacture while achieving precise knife guidance
Solution Approach 2:
The groove introduces local quality change to the support web by creating a specific geometric feature (recess) at the precise location where knife guidance is needed. The rest of the support web maintains its simple structure for easy manufacture, while the localized groove provides the necessary guidance function
