Solution Overview
Problem
Existing can manufacturing processes using dedicated press machines are costly and time-consuming, as they require precise specification setting and are difficult to repurpose for producing other products, leading to extended delivery times and increased costs.
Innovation Solution
A can manufacturing method and system utilizing a pre-step press machine for blank processing and coining, followed by a post-step press machine for drawing and ironing processing, with a conveyor to transfer blanks between machines, allowing for flexible production of various can sizes and types using general-purpose press machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dedicated press machine is designed and manufactured based on precise specifications, then manufacturing precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies universality by using a standard press machine that can perform multiple functions through interchangeable dies. Instead of designing a dedicated press machine for each can type, the system uses a single press machine that can be reconfigured by changing the die set, allowing one machine to produce various can shapes and sizes while maintaining manufacturing precision
Solution Approach 2:
The press machine system is segmented into modular components, particularly the die assembly that can be independently changed. The die is designed as a separate, replaceable component that defines the specific can geometry, while the press machine itself remains a standardized platform, reducing overall system complexity
2Manufacturing precision
If a dedicated press machine is designed and manufactured, then manufacturing precision is improved, but delivery time increases
Solution Approach 1:
The die is designed and prepared in advance as a standalone component that can be quickly installed on the standard press machine. This preliminary preparation of interchangeable tools allows the press machine to be rapidly reconfigured for different can types without undergoing lengthy redesign or remanufacturing processes
Solution Approach 2:
By using a universal press machine platform that can handle multiple can types through die changes, the system eliminates the need to manufacture dedicated machines for each product, significantly reducing delivery time while maintaining precision through properly engineered standardized equipment
3Manufacturing precision
If a dedicated press machine is used, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The press machine is designed as a universal platform that can produce multiple can types and sizes by changing the die. This multi-functionality allows the same machine to maintain manufacturing precision across different products while providing full adaptability to market demands without requiring dedicated equipment for each can variant
Solution Approach 2:
The system introduces dynamic reconfigurability through interchangeable dies, allowing the press machine to adapt its function based on production requirements. The die can be quickly changed to match different can specifications, enabling the system to dynamically respond to changing product demands while maintaining precision through standardized tooling
