Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current powder cell culture media products face issues with slow dissolution, clumping, poor flowability, dusting, and segregation, as well as the need for manual pH adjustment and supplementation, which complicates their use and handling.
Innovation Solution
A method is developed to create a rapidly dissolving, pH-pre-adjusted, and pre-buffered dry cell culture media powder by mixing dry ingredients with an aqueous solution to form a paste, drying it, and milling it into a homogeneous powder, which can dissolve quickly and consistently in water without the need for additional pH adjustment or supplementation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If powder cell culture media is prepared by add-milling ingredients to form powder, then manufacturing cost is reduced, but dissolution time increases and clumping occurs
Solution Approach 1:
The patent applies preliminary action by pre-mixing all media ingredients with binders and lubricants during the manufacturing process to form uniform granules before packaging. This preliminary mixing and granulation ensures that when the powder is later dissolved in water, all components are already evenly distributed and ready for rapid dissolution, eliminating the need for prolonged mixing during preparation.
Solution Approach 2:
The patent changes physical parameters of the media powder by controlling particle size distribution through granulation processes and adjusting moisture content to optimize dissolution characteristics. By modifying these physical parameters during manufacturing, the powder achieves rapid dissolution without requiring additional time during actual media preparation.
2Ease of manufacture
If powder cell culture media is prepared by add-milling ingredients to form powder, then manufacturing cost is reduced, but flow characteristics deteriorate
Solution Approach 1:
The patent applies local quality by adding different functional ingredients at specific stages of the manufacturing process. Binders are added during granulation to improve flow characteristics, while lubricants are added in controlled amounts to prevent clumping. This localized addition of materials with specific functions optimizes both flow characteristics and dissolution properties without compromising manufacturing efficiency.
3Ease of manufacture
If powder cell culture media is prepared by add-milling ingredients to form powder, then manufacturing cost is reduced, but dust content increases
Solution Approach 1:
The patent creates composite granular materials by combining media ingredients with binders and lubricants in specific ratios. This composite structure binds the fine powder particles together in granules, significantly reducing dust generation during handling and storage while maintaining the nutritional composition required for cell culture applications.
4Ease of manufacture
If powder cell culture media is prepared by add-milling ingredients to form powder, then manufacturing cost is reduced, but segregation occurs
Solution Approach 1:
The patent merges all media ingredients into uniform granules through a granulation process where binders and lubricants are added and mixed thoroughly. This merging of components into a homogeneous granular structure prevents segregation during storage and handling, ensuring that the composition remains uniform throughout the product lifecycle.
5Ease of operation
If liquid cell culture media is used, then ready-to-use convenience is achieved, but sterilization complexity increases
Solution Approach 1:
The patent creates a stable powder formulation that can be sterilized using conventional, cost-effective methods such as autoclaving or gamma irradiation. The powder form allows for complete sterilization of all components, and after sterilization, the media can be stored as a stable powder until use, eliminating the need for complex ongoing sterilization procedures required for liquid media.
6Ease of operation
If liquid cell culture media is used, then ready-to-use convenience is achieved, but shelf life decreases
Solution Approach 1:
The patent utilizes phase transition by converting the media from liquid to powder form. This phase change allows the media to be stored as a stable, dry powder with extended shelf life. When needed, the powder is rapidly reconstituted by adding water and mixing, providing ready-to-use convenience without compromising storage stability.
