Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for manufacturing and treating containers under cleanroom conditions are susceptible to contamination from the introduction of non-sterile components, which can negatively impact the quality of the containers and products.
Innovation Solution
A plant and method utilizing a clean room with sterilization-resistant materials for components that come into direct contact with preforms or containers, combined with sterilization devices and control units to manage sterilization media application based on sterility parameters, ensuring reliable sterilization and minimizing maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sterilization-resistant materials are used for components in contact with preforms/containers, then reliability of sterilization process is improved, but manufacturing cost increases
Solution Approach 1:
The patent applies sterilization-resistant materials specifically to components that come into direct contact with preforms or containers (such as molds, conveyors, and handling equipment), while other parts of the system may use standard materials. This localized application ensures sterilization reliability where needed while controlling overall manufacturing costs.
2Object-affected harmful factors
If frequent sterilization is performed, then purity of containers is improved, but wear and tear on components increases
Solution Approach 1:
The system performs sterilization of components and cleanroom environment at predetermined intervals and under controlled conditions, rather than continuously or ad hoc. This preliminary, scheduled approach maintains container purity while minimizing unnecessary exposure of components to sterilization media, thereby reducing wear and extending component service life.
3Reliability
If additional sterilization steps are introduced, then contamination prevention is improved, but device complexity increases
Solution Approach 1:
The patent integrates sterilization functionality directly into the existing production line equipment and cleanroom infrastructure, rather than adding separate standalone sterilization systems. The sterilization-resistant materials are incorporated into components already present in the production process, merging sterilization capability with production functionality and avoiding additional system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
