Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate external and internal application devices are used for sterilization, then sterilization effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines the external application device and internal application device into a single integrated sterilization device. The external application device applies accelerated charge carriers to the outer wall of preforms, while the internal application device applies charge carriers to the inner wall through the preform opening. Both functions operate within one unified system, reducing the need for separate devices while maintaining sterilization effectiveness.
Solution Approach 2:
The integrated sterilization device performs multiple functions: external sterilization of the outer wall, internal sterilization of the inner wall, and transport of preforms along a transport path. The single device handles both external and internal application of charge carriers, making it a multi-functional system that reduces overall device complexity.
2Productivity
If continuous processing with transport device is implemented, then productivity increases, but process complexity increases
Solution Approach 1:
The sterilization device enables continuous processing by transporting preforms along a transport path through the sterilization zone. The external and internal application devices continuously apply accelerated charge carriers to preforms as they move, eliminating batch processing interruptions and maintaining continuous sterilization action throughout the process.
3Manufacturing precision
If distance changing mechanism is added to optimize charge carrier application, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The distance changing mechanism dynamically adjusts the spacing between preforms on the transport path. This dynamic adjustment optimizes the application of accelerated charge carriers by ensuring proper spacing for effective sterilization while maintaining continuous flow. The mechanism responds to process requirements in real-time, improving manufacturing precision.
4Volume of stationary object
If compact design is achieved, then loss of space is reduced, but manufacturing precision may worsen
Solution Approach 1:
The patent arranges the external and internal application devices in a spatial configuration that optimizes space utilization. The internal application device accesses the inner wall through the preform opening while the external device treats the outer wall, utilizing different spatial dimensions and access paths. This dimensional arrangement enables compact design while maintaining sterilization precision for both internal and external surfaces.
