Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual production method is used, then flexibility and simplicity are maintained, but production quantity and efficiency cannot be increased
Solution Approach 1:
The spring roll making apparatus is divided into multiple independent functional modules: a supply part for providing rice papers, a softening part for treating the rice paper, a feeding part for adding filling, a folding part for shaping, and a rotating part for rolling. Each module performs a specific task, allowing the complex production process to be broken down into manageable segments that can be automated individually while maintaining overall system simplicity.
Solution Approach 2:
The softening part applies preliminary action by treating the rice paper with steam or hot water before the filling and folding processes. This pre-softening step makes the rice paper more pliable and easier to fold, which simplifies subsequent operations and enables automated processing without requiring complex force application mechanisms during the folding stage.
2Productivity
If automated process is implemented, then production efficiency increases, but manufacturing cost increases
Solution Approach 1:
The apparatus design incorporates universal components that can handle multiple functions. For example, the moving part serves both to transport the rice paper through the production line and to position it correctly for subsequent operations. The folding part not only folds the rice paper but also shapes the spring roll simultaneously. This multi-functionality reduces the total number of components needed, lowering manufacturing costs while maintaining high production speed.
Solution Approach 2:
The rotating part utilizes the natural rolling motion of the filled rice paper to complete the spring roll formation without requiring additional complex mechanisms. The filled rice paper is automatically rolled by the rotation of the apparatus, and the excess rice paper is naturally trimmed, reducing the need for separate trimming mechanisms and associated costs.
3Ease of operation
If rice paper is not softened, then process simplicity is maintained, but folding and rolling become difficult
Solution Approach 1:
The softening part applies preliminary action by treating the rice paper with steam or hot water before the filling and folding processes. This pre-softening step makes the rice paper more pliable and easier to fold, which simplifies subsequent operations and enables automated processing without requiring complex force application mechanisms during the folding stage.
Solution Approach 2:
The softening part changes the physical parameters of the rice paper by exposing it to steam or hot water, which increases the moisture content and flexibility of the rice paper. This parameter change transforms the rigid rice paper into a more pliable material that can be easily folded and rolled by the automated apparatus, significantly improving ease of operation.
