Innovative Design of a Rigid Package Container Applied in Ultra High Pressure Food Processing Based on TRIZ

An innovative structure of Rigid Package Container (RPC) was designed based on TRIZ for improving productivity. The technical contradiction of RPC was solved by TRIZ contradiction analysis methodologies and obtained solution principles. Then mechanical analysis on sealing process of o-rings and structural optimization on its key components of RPC were completed. Ultimately, optimized structures of RPC had been achieved. Experiments on the sealing properties had stated that this structure was reasonable and reliable in sealing, easy to assembly and disassembly, compact structure and light weight. Thus, this innovative RPC could be applied in many ultra high pressure vessels in food industry.
