Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement and control methods are used for ultrasonic stack amplitude, then device complexity is reduced, but measurement precision and control accuracy deteriorate
Solution Approach 1:
The patent implements feedback by embedding operational information (amplitude parameters, mechanical to electrical ratios) in smart ultrasonic components that communicate with the power supply. The power supply reads this information and automatically adjusts excitation signals to achieve desired amplitude, creating a closed-loop control system that improves measurement precision without requiring complex external measurement devices.
Solution Approach 2:
The smart ultrasonic components perform self-service by containing and providing their own operational information directly to the power supply. This eliminates the need for external measurement and calibration equipment, as each component essentially tells the power supply how to excite it properly, thereby improving precision while keeping the overall system simple.
2Adaptability or versatility
If components of ultrasonic stack are swapped, then adaptability is improved, but measurement precision deteriorates due to unknown mechanical to electrical ratios
Solution Approach 1:
The patent applies preliminary action by pre-storing operational information (amplitude parameters, mechanical to electrical ratios, serial numbers) within each smart ultrasonic component during manufacturing. When components are swapped, the power supply automatically reads this pre-stored information, eliminating the need for re-measurement and calibration, thus maintaining precision while enabling adaptability.
Solution Approach 2:
The embedded operational information acts as an intermediary between the ultrasonic component and the power supply. This information mediator allows the power supply to understand and properly control each component without direct physical measurement, enabling seamless component swapping while maintaining precise control through the information bridge.
3Reliability
If service life tracking is not implemented, then device complexity is reduced, but reliability deteriorates due to unknown component health status
Solution Approach 1:
The patent implements feedback for reliability tracking by having smart ultrasonic components continuously monitor and report their operational status, use cycles, and health parameters to the power supply. This automated feedback loop enables the system to track service life and predict failures without requiring complex external monitoring equipment, as the components themselves provide their health data.
4Productivity
If automatic amplitude control is implemented, then productivity is improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The smart ultrasonic components perform self-service by automatically providing their operational parameters and mechanical to electrical ratios to the power supply. This eliminates the need for manual setup and calibration procedures, significantly improving productivity. The control mechanism remains simple because the components themselves supply the necessary information, avoiding the need for complex external control systems.

AI summary
An ultrasonic system has an ultrasonic stack excited by a power supply. The ultrasonic stack has a plurality of components, including an ultrasonic converter, a booster and an ultrasonic horn. A method of controlling the ultrasonic system with the power supply includes upon replacing any of the components of the ultrasonic stack with a replacement component, inputting an amplitude parameter of the replacement component into the power supply, determining with the power supply an amplitude of an AC excitation signal at which to excite the ultrasonic converter based on amplitude parameters of the components including the amplitude parameter of each replacement component. The power supply then sets the amplitude of the AC excitation signal at this determined amplitude.
