Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional single-stage element array plate is used, then the device structure is simple, but the system cannot selectively treat specific body parts or provide intensive treatment to deep areas
Solution Approach 1:
The element array plate is divided into two distinct stages: a first stage for shallow area treatment and a second stage for deep area treatment. Each stage has optimized piezoelectric elements configured for specific depth ranges, enabling selective treatment of different body parts while maintaining manageable structural complexity through modular design
Solution Approach 2:
The patent transitions from a single-plane element arrangement to a multi-layer three-dimensional configuration. The first and second stages are positioned at different depths, creating a vertical dimension that enables selective focusing at various depths simultaneously, thereby achieving intensive treatment capability for both shallow and deep areas
2Reliability
If the irradiation dose is increased to ensure treatment effectiveness, then treatment efficacy improves, but normal tissues may be destroyed causing safety problems
Solution Approach 1:
Each stage of the element array plate is optimized with specific piezoelectric element configurations tailored to its designated depth range. The first stage uses elements optimized for shallow tissue penetration while the second stage uses elements optimized for deep tissue penetration, allowing precise local treatment without excessive energy delivery to superficial normal tissues
Solution Approach 2:
The system incorporates detection sensors that provide real-time feedback on treatment progress and tissue response. This feedback mechanism allows the controller to dynamically adjust irradiation parameters, ensuring sufficient dose delivery to target areas while preventing excessive dosing that could damage normal tissues
3Measurement precision
If conventional ultrasound therapy is used without real-time detection, then the system is simpler to operate, but healing effects cannot be observed at the right time and treatment dosage cannot be precisely controlled
Solution Approach 1:
Detection sensors are integrated into the system to provide real-time feedback on treatment progress and tissue response. This feedback loop enables precise control of irradiation dosage by allowing the controller to adjust parameters based on actual treatment conditions, while the user interface maintains ease of operation through automated control
4Reliability
If a single-stage element array plate is used, then the device is simpler and faster to manufacture, but the system lacks stability and cannot provide intensive treatment to specific parts
Solution Approach 1:
The element array plate is segmented into two independently manufacturable stages that can be produced using standardized processes. This segmentation allows each stage to be optimized for its specific function while maintaining manufacturing efficiency, and the modular design facilitates quality control to ensure system stability
Solution Approach 2:
The patent optimizes specific parameters of the piezoelectric elements in each stage, such as element size, spacing, and electrical connectivity, to achieve stable performance. These parameter optimizations are implemented through precise manufacturing tolerances and quality control procedures that ensure consistent results across production batches
