Drum-Based Spring Roll Skin Forming for Versatile Batter Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring roll manufacturing apparatuses are limited in using skins made of materials or textures other than pre-manufactured rice paper, and the bonding area is restricted, affecting the completeness of the spring rolls.
Innovation Solution
A skin formation module with a drum, heating unit, and batter spray unit forms skins of various materials, and a cutting module increases the bonding area by cutting the skin into a shape with a large surface area, while a powder module enhances texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-manufactured rice paper is used as the skin, then the manufacturing process is simple and easy to operate, but the adaptability to different skin materials and textures is limited
Solution Approach 1:
The patent replaces the mechanical system of using pre-manufactured rice paper with a chemical/biological system by introducing a batter spray unit that applies liquid batter onto the drum surface. This allows the skin to be formed from various batter materials rather than being limited to pre-made rice paper, thereby improving adaptability while maintaining operational simplicity through automated spraying
Solution Approach 2:
The patent changes the physical state parameter of the skin material from solid pre-manufactured rice paper to liquid batter that is sprayed and then cooked on the drum. This parameter change enables the use of various batter compositions and textures, improving versatility while the automated process maintains ease of operation
2Ease of operation
If square rice paper is used in a diamond shape, then the insertion process is simple, but the bonding area is limited
Solution Approach 1:
The patent transitions from a two-dimensional square rice paper format to a three-dimensional curved skin surface that wraps around the drum. This dimensional change creates a larger surface area for bonding while the automated spraying process maintains operational simplicity. The skin conforms to the drum's curvature, maximizing the bonding area compared to flat square paper
3Adaptability or versatility
If a skin formation module is added to manufacture skins separately, then the adaptability to various skin materials is improved, but the device complexity increases
Solution Approach 1:
The skin formation module with the drum and batter spray unit serves multiple functions: it forms the skin from various batter materials, cooks the skin simultaneously through heating, and provides a consistent curved shape. This multi-functionality improves adaptability while minimizing the increase in device complexity by combining formation and cooking in one integrated unit
Solution Approach 2:
The patent segments the spring roll manufacturing process into distinct modules: the skin formation module (with drum and spray unit), the filling insertion module, and the rolling module. This segmentation allows the skin formation module to be independently optimized for various materials while keeping the overall system complexity manageable through modular design
