Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If impedance matching circuits are added to each ultrasonic transducer to achieve maximum output, then ultrasonic wave output is maximized, but manufacturing cost increases and manufacturing time is extended
Solution Approach 1:
The electric pulse generating device is designed with universal adaptability to work with multiple different ultrasonic transducers without requiring individual impedance matching circuits for each transducer. The controller automatically adjusts operating parameters based on transducer characteristics stored in memory, making the system multi-functional and eliminating the need for additional matching circuits.
Solution Approach 2:
A memory device serves as an intermediary between the electric pulse generating device and ultrasonic transducers. The memory stores characteristic information of different transducers, enabling the controller to automatically adapt to varying transducer impedances and resonance frequencies without requiring physical impedance matching circuits.
2Power
If impedance matching circuits are added to each ultrasonic transducer to achieve maximum output, then ultrasonic wave output is maximized, but manufacturing time is extended
Solution Approach 1:
Characteristic information of ultrasonic transducers (including impedance and resonance frequency data) is pre-stored in the memory device during the manufacturing process. This preliminary action eliminates the need for time-consuming impedance matching circuit assembly and adjustment during final device manufacturing, as the system is pre-configured to adapt to different transducers.
Solution Approach 2:
The electric pulse generating device with integrated memory serves as a universal platform that can work with multiple different ultrasonic transducers without requiring individual customization or additional matching circuits for each transducer, significantly reducing manufacturing time.
3Reliability
If ultrasonic transducers are frequently replaced to extend system life span, then system reliability is improved, but impedance matching difficulty increases
Solution Approach 1:
The controller reads characteristic information of replaced ultrasonic transducers from the memory device and automatically adjusts operating parameters based on this feedback. This enables seamless replacement of transducers without requiring manual impedance matching, as the system automatically adapts to the new transducer's characteristics.
Solution Approach 2:
The electric pulse generating device dynamically adjusts its operating parameters (frequency, voltage, current) based on the specific characteristics of the connected ultrasonic transducer. This dynamic adaptation allows frequent transducer replacement without impedance matching issues, as the system continuously optimizes its operation for each transducer.
4Power
If resonance frequency is increased to improve ultrasonic wave output intensity, then output intensity is improved, but manufacturing precision requirements increase
Solution Approach 1:
Instead of relying on precise manufacturing to achieve high resonance frequencies, the system changes operating parameters (frequency, voltage, current) through electronic control based on stored transducer characteristics. This allows high output intensity to be achieved through parameter optimization rather than through difficult manufacturing precision requirements.
Solution Approach 2:
The memory device stores precise characteristic information of each ultrasonic transducer, serving as an intermediary that enables the controller to precisely control operating parameters. This eliminates the need for high manufacturing precision in the transducer itself, as precision is achieved through electronic parameter adjustment based on stored data.

Implementation Method 1
An ultrasonic transducer may be formed by making a piezoelectric resonant by forming electrodes on both sides of a piezoelectric element or by coupling a case to a piezoelectric resonant. If an electric pulse is applied to the electrodes of the piezoelectric resonant, the piezoelectric element resonates to generate ultrasonic wave.
