Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microarray packaging systems are costly, complex, and inefficient for industrial-scale manufacturing, requiring additional decontamination steps, being difficult to handle, and not suitable for high-speed production or user convenience, especially for partially finished microarrays that need protection during manufacturing steps.
Innovation Solution
A packaging article comprising connected outer pouches with shared sealed edges and an inner pouch, made of materials with oxygen and water barrier properties, allowing for easy handling and integration with pick-and-place machines, and accommodating partially finished microarrays for coating and sterilization processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom-made packaging is used to protect microarrays during transport and storage, then protection reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The packaging is divided into an outer pouch and an inner pouch as separate but connected components. The outer pouch provides structural protection and barrier properties, while the inner pouch provides additional protection and containment. This segmentation allows each pouch to be optimized for its specific function, improving overall protection without requiring a single complex packaging system.
Solution Approach 2:
The inner pouch is nested within the outer pouch, with the open end of the inner pouch aligned to the open end of the outer pouch. This nested configuration allows both pouches to work together synergistically, providing enhanced protection while maintaining a compact and simple overall structure that is easy to manufacture and handle.
2Reliability
If custom-made packaging is used for microarrays, then protection is improved, but manufacturing speed and productivity decrease
Solution Approach 1:
The packaging system is segmented into standardized outer and inner pouches that can be manufactured independently and assembled efficiently. This segmentation enables parallel manufacturing processes and simplifies the assembly steps, allowing for high-speed production while maintaining protective functionality.
Solution Approach 2:
The outer pouch design with connected pouches and shared sealed edges can be used for multiple microarray devices simultaneously. This universal design reduces the number of individual packaging operations required and enables streamlined manufacturing processes that maintain protection while increasing productivity.
3Loss of substance
If connected outer pouches with shared sealed edges are used, then material usage is reduced, but seal complexity increases
Solution Approach 1:
Adjacent outer pouches share common sealed edges, merging the sealing functions into single continuous seals rather than requiring separate seals for each pouch. This merging reduces the total amount of sealing material and operational complexity while minimizing overall material usage through the connected pouch design.
Solution Approach 2:
The shared sealed edges serve multiple functions: they seal individual pouches, connect adjacent pouches, and provide structural integrity to the overall packaging system. This multi-functionality reduces the need for additional sealing components and simplifies the overall seal design while achieving material efficiency.
