The need to optimize the design of the structural node or the entire technical system returns the structural design or the whole production documentation back to the engineer's drawing board. Incentives to changes may occur in another lifecycle phase of the technical system. If a need to optimize arises, the engineer has more methods to choose from. One of the prefered methods to optimize is the method of TRIZ. We use it to optimize or alternatively to create a new construction design of assembly units for automated branches of ultrasonic welders. By using the method of TRIZ, we eliminate the low stiffness of mounting sonotrode, low variability of setting, low variability of sonotrode placement, we increase the number of combinations of sonotrode mounting and we simplify the construction design, assembly, production and following maintenance.
