Innovation Solution
An apparatus and method using a trained algorithm or computing system to count flash sounds generated by the treatment device, segmenting audio signals, extracting characteristic features, and detecting flash sounds to accurately track the number of pulses, with features like MFCCs and XGBoost classification, and providing user interface feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate devices are used to perform different functions (e.g., device for applying treatment, device for determining treatment parameters, device for monitoring treatment), then each device can be optimized for its specific function, but the overall system complexity increases and requires multiple devices to be coordinated
Solution Approach 1:
The patent combines multiple previously separate devices into a single integrated treatment device. The device for applying treatment, the device for determining treatment parameters, and the device for monitoring treatment are merged into one unified system, eliminating the need for multiple separate devices while maintaining all required functions
Solution Approach 2:
The treatment device is designed with multi-functionality to perform multiple tasks: applying treatment to the subject, determining treatment parameters based on subject characteristics, and monitoring the treatment progress. This universal device replaces several specialized devices with one versatile system
2Measurement precision
If treatment parameters are determined based on detailed subject characteristics (age, weight, medical history, etc.), then treatment precision and safety improve, but the time and complexity of treatment setup increase
Solution Approach 1:
The system performs preliminary data collection and processing by gathering subject characteristics (age, weight, medical history, etc.) before treatment begins. The processor pre-determines appropriate treatment parameters based on this data, so that when treatment starts, the parameters are already optimized and ready for immediate application
Solution Approach 2:
The monitoring device continuously monitors treatment progress and provides feedback to the processor. Based on this feedback, the system can adjust treatment parameters in real-time, ensuring optimal treatment while reducing the need for extensive pre-treatment setup time
3Ease of operation
If the treatment device is designed to be portable and movable, then accessibility and ease of use improve, but the power supply reliability and treatment consistency may be compromised
Solution Approach 1:
The device incorporates a rechargeable battery power supply that enables portable operation. The system dynamically adapts between battery-powered portable mode and mains-powered stationary mode, allowing the device to maintain reliability while providing mobility when needed
Solution Approach 2:
The power supply system can change its operational parameters between battery operation and mains operation. The device monitors power availability and adjusts its operation accordingly, ensuring consistent treatment delivery regardless of the power source being used
