Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional ultrasound therapy systems are used for postpartum uterine therapy, then therapy function is provided, but the systems are bulky, have complicated operation, poor configurability and low therapeutic efficiency
Solution Approach 1:
The system divides the ultrasound transducer into multiple independently controllable elements arranged in an array. Each element can be individually activated or deactivated through electronic control, enabling flexible configuration of therapy patterns without mechanical complexity. This segmentation allows the system to achieve multiple therapy modes through software control rather than hardware reconfiguration.
Solution Approach 2:
The ultrasound array system is designed to perform multiple therapy functions including static therapy, dynamic scanning therapy, and focused therapy through electronic beamforming control. The same hardware platform supports different therapy protocols by adjusting activation patterns of array elements, eliminating the need for multiple specialized devices and reducing operational complexity through unified control interfaces.
2Productivity
If traditional dynamic therapy mode is used, then therapy is provided, but medical staff must constantly move the probe which reduces therapeutic efficiency and increases operation complexity
Solution Approach 1:
The system replaces mechanical probe movement with electronic beam steering by selectively activating array elements in different sequences. The electronic control system can dynamically adjust the active element pattern to scan across the uterine area without physical movement, maintaining the benefits of dynamic therapy while eliminating the need for constant manual probe repositioning and improving therapeutic efficiency.
Solution Approach 2:
The system provides both static and dynamic therapy modes through electronic control of array element activation. In dynamic mode, different groups of elements are activated in sequence to create moving therapy zones without physical probe movement. This dynamic element activation allows flexible adaptation to therapy needs while simplifying operation compared to manual probe manipulation.
3Productivity
If low-intensity ultrasound is used for static therapy, then therapeutic efficiency is improved, but hot spots may still form requiring complex monitoring and adjustment
Solution Approach 1:
The system monitors and controls ultrasound intensity at different spatial locations by selectively activating specific array elements. When hot spots are detected through feedback from detection transducers, the control system locally adjusts the activation pattern or intensity of specific elements to eliminate the hot spot while maintaining therapy at other locations. This localized control maintains therapeutic efficiency while ensuring safety.
Solution Approach 2:
The system incorporates detection transducers that continuously monitor the ultrasound field during therapy and provide feedback to the control system. This feedback mechanism enables real-time detection of hot spots and automatic adjustment of the active element pattern or intensity levels, ensuring reliable hot spot control while maintaining high therapeutic efficiency through adaptive low-intensity ultrasound delivery.
