Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a defibrillator device is made portable and integrates with mobile phones, then ease of operation and portability are improved, but the device complexity increases due to integration requirements
Solution Approach 1:
The patent combines the defibrillator device with a mobile phone into an integrated system. The mobile phone serves multiple functions including serving as the control unit, power source via USB interface, and communication device. This merging reduces the need for separate carrying of defibrillator and phone, improving portability and ease of operation while managing complexity through unified design
Solution Approach 2:
The mobile phone in the system performs multiple functions: it acts as the control unit for the defibrillator, provides power through USB charging interface, serves as a communication device for emergency calls, and can store patient information. This multi-functionality eliminates the need for separate dedicated devices, improving ease of operation and portability
2Ease of operation
If the defibrillator uses USB interface for power and control, then ease of operation is improved, but the power delivery capability may be insufficient for high-voltage defibrillation
Solution Approach 1:
The control unit (mobile phone) acts as an intermediary between the low-power USB interface and the high-voltage stimulation module. It receives charging input via USB, manages power conversion, and controls the defibrillation discharge timing and parameters, enabling easy USB-based operation while achieving required defibrillation power levels
Solution Approach 2:
The system transforms the electrical parameters from the low-voltage USB charging interface to the high-voltage requirements of the defibrillation stimulation module. The control unit manages this parameter transformation, converting readily available USB power into the high-voltage pulses needed for defibrillation

Implementation Method 1
According to a first voltage from a portable electronic device, the voltage converter generates a second voltage when the first USB interface is coupled to the portable electronic device, wherein the second voltage is higher than the first voltage
Implementation Method 2
The stimulation module provides electric shock energy to the chest of the patient via the first and second electrodes according to the second voltage when the first physiologic rhythm signal indicates that cardiac arrhythmia is present in the patient
Data Source
AI summary
A defibrillator device is provided. The defibrillator device includes a first electrode, a second electrode, a readout module, a USB interface, a voltage converter and a stimulation module. When the first and second electrodes contact the chest of a patient, the readout module obtains a physiologic rhythm signal of the patient and provides a heart rhythm signal according to the first physiologic rhythm signal. According to a first voltage from a portable electronic device, the voltage converter generates a second voltage when the first USB interface is coupled to the portable electronic device, wherein the second voltage is larger than the first voltage. When the physiologic rhythm signal indicates that cardiac arrhythmia is present in the patient, the stimulation module provides an electric shock energy to the chest of the patient via the first and second electrodes according to the second voltage.
