Motorized Fish Skinner with Pivoting Blade and Roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing fish skin during preparation are inefficient and lack a dedicated, user-friendly device for separating skin from fish meat, particularly for freshwater fish like Walleye, perch, crappie, blue gill, bass, and Northern Pike.
Innovation Solution
A fish skinning device comprising a support body, a drive shaft, a roller, a pivotally connected blade, and a lever, allowing the blade to move between parallel and angled positions relative to the roller, powered by a motor for efficient skin removal, constructed from heat-resistant and waterproof materials like stainless steel and plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a knife is used to manually cut the skin from the fish flesh, then the device complexity is low, but the productivity and efficiency of skinning are poor
Solution Approach 1:
The patent replaces the manual mechanical cutting action with a motorized system. A motor drives a roller that rotates against the fish skin, using mechanical friction and a blade to automatically separate the skin from the flesh, thereby increasing productivity while accepting increased device complexity
Solution Approach 2:
The fish skinning device allows the fish itself to be fed through the mechanism, where the roller and blade system automatically performs the skinning action as the fish passes through, reducing the need for continuous manual intervention and improving overall skinning efficiency
2Adaptability or versatility
If the blade is fixed in position, then the device complexity is low, but the adaptability to various fish types and sizes is poor
Solution Approach 1:
The patent implements a movable blade that can adjust its position and angle relative to the roller. This dynamic adjustment capability allows the blade to adapt to different fish sizes and skin characteristics, improving versatility while accepting the added complexity of movable components and adjustment mechanisms
3Productivity
If the blade applies high force to remove skin quickly, then the productivity is high, but the fish meat may be damaged
Solution Approach 1:
The patent employs a sharp, precisely positioned blade that applies force only at the interface between the roller and the fish skin. This localized cutting action separates the skin from the flesh with minimal force applied to the meat itself, maintaining meat integrity while achieving efficient skin removal through the roller-blade interaction
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively separates fish skin from meat with adjustable force and speed, ensuring efficient skinning while being user-friendly and adaptable for various fish types, with the motor providing sufficient torque and speed for efficient operation.
Implementation Method 1
a roller connected to the drive shaft
Implementation Method 2
The blade and roller cooperate to separate the skin from the flesh of the fish
Implementation Method 3
a blade support pivotally connected to the support body; a lever fixedly connected to the blade support for pivoting the blade support

AI summary
A fish skinning device is disclosed. In one or more implementations, the fish skinning device includes a support body, a drive shaft configured to rotate with respect to the support body; a roller connected to the drive shaft; a blade support pivotally connected to the support body; a blade connected to the blade support; and a lever fixedly connected to the blade support for pivoting the blade support about the support body between a first position where the blade is adjacent the roller and at least substantially parallel with the roller, and a second position where the blade is pivoted away from the roller with respect to the first position.
