Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the throwing method is used to deliver bread slices, then the delivery speed is fast, but the accuracy of the landing point cannot be guaranteed
Solution Approach 1:
The patent replaces the traditional throwing method with a mechanical pushing system using a push plate driven by a ball screw mechanism. This substitution eliminates the randomness of throwing while maintaining efficient delivery speed, achieving both speed and precision requirements for bread slice placement.
Solution Approach 2:
The push plate is designed to move dynamically along a predetermined trajectory controlled by the ball screw mechanism. This dynamic control allows the push plate to deliver bread slices accurately to the landing point while maintaining high delivery speed through controlled motion.
2Device complexity
If the direct pushing method is used to deliver bread slices, then the delivery process is simple, but the sandwich shifts during pushing causing appearance deterioration
Solution Approach 1:
The push plate serves as an intermediary tool between the delivery mechanism and the bread slice. It provides a controlled interface for pushing bread slices along a predetermined trajectory, preventing sandwich shifting while maintaining operational simplicity through the automated ball screw mechanism.
Solution Approach 2:
The system pre-defines the pushing trajectory and control points before actual delivery. The ball screw mechanism is pre-positioned and the push plate follows a predetermined path, ensuring sandwich position accuracy is maintained throughout the pushing process without requiring complex real-time adjustments.
3Device complexity
If a fixed storage barrel is used in the packaging machine, then the structure is simple, but the storage bucket cannot be flexibly replaced causing operational inconvenience and hygiene issues
Solution Approach 1:
The storage system is segmented into a removable bread receptacle and a fixed bread receptacle base. The receptacle can be easily extracted and replaced like a drawer, providing operational flexibility and hygiene benefits while maintaining structural simplicity through the modular design. The geometric center alignment ensures stable operation during the pushing process.
