Solution Overview

Problem

Existing cell culture media containers are bulky, inefficient for shipping, require large storage space, and introduce variability due to manual handling and potential contamination, increasing costs and resource usage.

Innovation Solution

A collapsible container system with rigid ends and a deformable middle portion that expands on demand, allowing for efficient shipping and mixing of powdered media with water to create cell culture solution, featuring recyclable materials and sterilization protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If cell culture media is packaged in bulk liquid bottles, bags, or drums, then the media can be stored and transported, but the containers become bulky and space-inefficient, increasing shipping costs and storage requirements

Engineering Contradiction:
Improvecell culture media volumeVSAvoidcontainer volume
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The patent changes the physical state of cell culture media from liquid to powder form, enabling compact packaging. The powder media can be densely packed in small containers that expand only when filled with liquid at the point of use, dramatically reducing shipping and storage volume while maintaining the required quantity of media.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention segments the cell culture media into concentrate powder and diluent liquid components. The powder concentrate is packaged in compact, space-efficient containers that can be shipped and stored in minimal space, then reconstituted with liquid at the point of use to achieve the required volume.

Inventive Principle:
Principle #1Segmentation

2Reliability

If engineers and scientists manually add components to media and resterilize, then contamination risks are addressed, but manual steps increase process variability and time consumption

Engineering Contradiction:
Improvecontamination preventionVSAvoidmedia preparation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent performs sterilization and component formulation in advance during powder media manufacturing. The pre-sterilized powder concentrate is sealed in sterile containers, eliminating the need for manual sterilization steps at the point of use and reducing process variability while maintaining contamination prevention.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables self-sterilization through sterile barrier packaging that maintains sterility until use. The powder media and associated components are packaged in sterile, sealed containers that prevent contamination without requiring manual sterilization intervention, thereby improving productivity while maintaining reliability.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If large storage areas are provided for bulky containers, then various cell culture medias are available on-demand, but storage space requirements and associated costs increase

Engineering Contradiction:
Improvemedia availabilityVSAvoidstorage area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Changing media form from liquid to powder enables compact storage. Multiple media types can be stored in small, space-efficient containers in the same footprint that previously held a single bulky liquid container, allowing diverse media availability in minimal storage space.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The compact powder containers can be nested or stacked efficiently in storage areas. The space-efficient design allows multiple containers to be stored in a fraction of the space required for traditional bulky liquid containers, reducing storage area requirements while maintaining media variety and availability.

Inventive Principle:
Principle #7Nested doll (Nesting)
