| dc.description.abstract | Biomedical Technology has been continuously developed as time goes by. The main purpose is to increase the life-span of human being and to provide better lives, when we look from business aspect, there’s a great market behind it. After lots of manpower and material resources are involved in, this field will become the fast-developing and fascinating industry. At this moment, the mostly used liquid nitrogen specimen storage systems can be divided into two types, the Traditional Lid-Open type and Auto-Mechanics type. The examples of Traditional Lid-Open type are the K series and LABS series of Taylor-Wharton, the MVE Eterne series of CHART…etc.; the Cryo-Cell of Cryo-Cell systems and the Thermogenesis of BioArchive system…etc. are in the Auto-Mechanics category.
This main purpose of this essay is to continue developing the mass volume liquid nitrogen specimen storage systems designed in this laboratory. Taking the reference of other products with the same functions and the proto small volume storage system designed in this laboratory, reserving the advantages of using and preserving, also improving the defects, to design a better ultra-low temperature (-196℃) storage system, which will be referred to The Second Generation System.
In the research, the effort was on design-analyze and manufacture testing. For design-analyze, the model of The Second Generation System is built up by using 3D drafting software, and then used pack software to process the finite element analyzing of the correlated and complex construction, also analyzing the strength of the structure. Before actually manufacturing, those steps helped realize if there are any defects of the design and reduced the budget and eliminated the trouble. And for manufacturing testing, the goal of this system is mass producing, the design must not only fit in the requirement, but also take care the method and the procedure of manufacturing. If it’s difficult for manufacturing process, then it’s also very fatal to pre-products. With the data of design-analyze for support, and after times of experiments, the performance control and the defects improvement go further. The design-analyze and the manufacture testing are the major purposes and directions of the essay.
The result of the research: the finite element analyzing and the result of casting showed the main spirit of The Second Generation System feasible. Comparing to the proto systems, The Second Generation System is with the properties of modulizing and expanding, the volume can also be increased to 2944 storage compartments. Without any electricity, simple mechanical design makes the specimen storing and drawing step signalized. The prevention of influencing the biological activity of other specimen is achieved with this method. At the end, synchronizing the procedures with software interface will optimize the product design.
