Triz Improvement of Rotary Compressor Design

A rotary compressor with variable capacity is used in air conditioners. An air conditioner is a key product of mass production of Digital Appliance Business of Samsung Electronics Company. Therefore the improvement of design and reliability of air conditioners leads to expansion of the sale and helps the company to preserve leadership position in the worldwide market. In this article the real industrial problem related to removing harmful interaction between compressor components “shaft-pin-double camroller-cylinder” and destruction problem of driving pin and cam bush were solved with ARIZ application. It is considered to use into the applied algorithm some new approaches and statements for reforming initial customer’s problem in the line of the future solutions. The development of different new designs of the compressor and its latching mechanism with the aid of applied ARIZ has been analyzed. The outcome of this work obtained with using applied logical algorithm tools are 21 concept solutions combined in 9 international and national patents and application of some of them in mass production of the company with annual income about $10 Million. This article could be useful for TRIZ users like real case study with measured results and how ARIZ was used to develop the solutions.
