Function Aggregation of New Heavy Load High Voltage Circuit Breaker Based on Axiomatic Design

To unify the design process of complex products to meet higher function and performance demands, a practical implementation for a new heavy load high voltage circuit breaker is presented. This paper analyzes the function and performance of a new heavy load high voltage circuit breaker, and addressed needs of being quick, accurate and stable. The superiority of the physical functional basis description method over the traditional functional basis model was demonstrated. The axiomatic design theory is described systematically and in detail using the function decomposition of the high voltage circuit breaker as an example. The concept of functional aggregation unit as the extension and expansion of axiomatic design theory is presented. This aggregation unit extracts essential characteristics of function and performance separately from their concrete structures, avoiding limits of the spring operating mechanism structure caused by reliance on a conventional structure. This function aggregation design method is presented for the design of a transmission unit. These results are of great theoretical significance to guide product innovation based on functional aggregation in axiomatic design theory.
