Sushi Roll Forming Apparatus Using Continuous Mat and Rod Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually rolling sushi is challenging for home cooks due to the complexity and difficulty in quickly and easily making sushi rolls, with existing solutions being cumbersome and hard to clean.
Innovation Solution
An apparatus with a front rod and a back rod wrapped by a continuous, food-grade mat that forms a longitudinal pocket for filling, allowing for easy formation and removal of sushi rolls without the need for gears, using the mat's gripping properties to encase the filling in a wrapper as the rods rotate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional sushi rolling method is used, then the sushi can be made, but the process is challenging and time-consuming for home cooks
Solution Approach 1:
The patent introduces a continuous mat as an intermediary tool between the user and the sushi ingredients. The mat is wrapped around two rods to form a longitudinal pocket that holds the filling, serving as a mediator that simplifies the rolling process. Users simply place ingredients in the pocket and rotate the rods, eliminating the need for manual rolling techniques.
Solution Approach 2:
The apparatus segments the sushi making process into distinct functional components: two rods for rotation, a continuous mat for forming the pocket, and a wrapper for encasing the filling. This segmentation allows each component to perform its specific function efficiently, making the overall process faster and easier compared to traditional manual methods.
2Ease of manufacture
If existing sushi making solutions are used, then sushi rolls can be formed, but the devices are cumbersome and hard to clean
Solution Approach 1:
The patent extracts the complex mechanical components (gears, motors, etc.) from the sushi making device, leaving only two simple rods that users rotate manually. This extraction simplifies the construction and makes cleaning straightforward, as there are no intricate parts to disassemble or maintain.
Solution Approach 2:
Instead of using a complex mechanism to move the sushi through a device, the patent inverts the approach by having the user rotate rods that bring the mat and filling to the user. This inversion simplifies the device structure and makes it easier to clean, as all components are accessible and can be removed for washing.
3Ease of operation
If a continuous mat is used to form the longitudinal pocket, then the filling can be easily enclosed, but the mat must have specific gripping properties without adhering to the filling
Solution Approach 1:
The continuous mat is designed with local quality variations: it has gripping properties on its outer surface that contact the rods (providing friction for rotation) while having non-adhering properties on its inner surface that contacts the filling (allowing easy release). This local differentiation of surface properties enables the mat to both grip the rods for rotation and release the finished roll easily.

Function Achieved in This Case
The apparatus simplifies the process of forming sushi rolls, reduces cleaning complexity, and allows for easy adjustment of roll size by varying rod diameters, making it accessible and efficient for home use.
Implementation Method 1
a continuous mat... which grips without adhering to an external longitudinal surface of the first rod and the second rod... when the first rod is rotated in a first direction the continuous mat causes the second rod to rotate in the first direction

AI summary
An apparatus and a method relate to forming a filled roll, a sushi roll with a nori seaweed wrap, for example. An issue arises in quickly and easily forming the filled roll at a place of convenience at home, for example. The present disclosure addresses the issue by providing the apparatus with two horizontal rods, front and back rods, the back rod positioned higher than the front rod. The rods are wrapped and connected by a continuous mat that grips without adhering to the rods and the filling. The back rod is positioned higher than the front rod. The continuous mat forms a longitudinal pocket between the two rods to receive filling. Rotating one of the two rods in one direction causes the filling to roll and forms a roll. The filled roll arises from the longitudinal pocket for removal while rotating the rods in another direction.
