Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cryogenic storage containers are made rigid to protect biological material, then structural strength is improved, but susceptibility to shock damage increases due to brittleness at low temperatures
Solution Approach 1:
The patent applies beforehand cushioning by placing shock-absorbing material between the rigid cryogenic storage container and the external environment before shock occurs. The cushioning material is positioned in advance within the container structure to absorb impact forces during transport, preventing direct transmission of shock to the brittle frozen contents while maintaining the rigid container's structural strength.
2Reliability
If shock absorbing material is added to protect frozen biological material, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent employs flexible shells and thin films by using a deformable inner bag or liner within the rigid cryogenic container. This flexible element can deform under shock loads to absorb impact energy, protecting the frozen biological material without requiring complex rigid shock-absorbing structures. The flexible film approach simplifies the overall device complexity while maintaining reliability.
3Stability of the object's composition
If rigid containers are used to organize and protect biological material in cryogenic freezers, then storage organization is improved, but transmission of shock and vibration during shipping increases
Solution Approach 1:
The patent applies composite materials by combining rigid outer container walls for structural strength and organization with an inner layer of shock-absorbing material or flexible liner. This composite structure maintains the rigid container's ability to organize and protect biological material in cryogenic freezers while the inner composite layer absorbs and dampens shock and vibration during shipping, preventing harmful force transmission to the contents.

AI summary
A shock absorbing device to protect cryogenically frozen biological material includes an outer sleeve and a foam sleeve. The outer sleeve defines an interior volume and has an opening configured to pass a biological material container into the interior volume. The foam sleeve is in the interior volume and has an opening and an interior cavity. The opening of the foam sleeve is aligned with the opening of the outer sleeve to pass the biological material container into the interior cavity. In another embodiment, the shock absorbing device includes a first layer, a foam layer, and a liner layer to retain the foam layer. A first side of the foam layer is adjacent and facing a second side of the first layer. A first side of the liner layer is adjacent and facing a second side of the foam layer.
