Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional ultrasonic irradiation devices are used, then ultrasound can be delivered to body tissues, but the accuracy of focusing ultrasound on specific parts without damaging normal tissues is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where cavitation information is acquired from the body during ultrasonic irradiation, and this information is used by the processor to control the ultrasonic irradiator in real-time. The system adjusts ultrasonic energy delivery based on detected cavitation signals, ensuring precise focusing on target areas while preventing damage to normal tissues through continuous monitoring and adaptive control.
Solution Approach 2:
The patent applies preliminary action by using the processor to determine optimal irradiation parameters and control the ultrasonic irradiator before actual treatment begins. The system pre-establishes the relationship between cavitation information and ultrasonic energy application, and pre-configures the irradiation strategy based on the acquired cavitation data, ensuring accurate targeting from the start of treatment.
2Productivity
If conventional ultrasonic irradiation devices require manual operation by doctors, then treatment can be controlled, but the irradiation time cannot be shortened and the ultrasonic irradiation effect cannot be maximized
Solution Approach 1:
The patent implements self-service by enabling the ultrasonic irradiation system to automatically control its own operation based on acquired cavitation information. The processor autonomously determines when and where to apply ultrasonic energy without requiring continuous manual intervention from doctors. This automated feedback-controlled system maximizes the ultrasonic irradiation effect while optimizing treatment time through intelligent, real-time decision-making.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting ultrasonic irradiation parameters (energy levels, timing, positioning) based on the acquired cavitation information. The processor modifies irradiation parameters in real-time according to the detected cavitation signals, optimizing the balance between treatment effectiveness and irradiation time without requiring manual recalibration by operators.
