Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carbon dioxide is administered subcutaneously using conventional devices, then the treatment can be delivered, but the procedure is considered irritating and slow
Solution Approach 1:
The patent implements dynamic control of CO2 flow through a solenoid valve that can be rapidly opened and closed (activation frequency >0.5 Hz), allowing the system to adapt the flow regime dynamically. This enables switching between continuous and pulsed flow modes to optimize both treatment speed and patient comfort, resolving the contradiction between fast delivery and irritation reduction
Solution Approach 2:
The patent employs periodic pulsed flow of carbon dioxide by rhythmically opening and closing the solenoid valve. This periodic action allows the CO2 to be delivered in controlled bursts rather than continuous stream, which reduces irritation while maintaining effective treatment dosage, thereby addressing both speed and comfort requirements
Solution Approach 3:
The patent changes physical parameters of CO2 delivery including flow rate, pressure, and temperature. By heating the CO2 to body temperature and regulating flow rate dynamically, the system optimizes the gas properties to reduce irritation. The ability to adjust activation frequency and duty cycle allows parameter optimization for both speed and comfort
2Loss of time
If conventional carboxytherapy devices are used, then treatment can be administered, but the treatment duration is long and tedious
Solution Approach 1:
The patent ensures continuous effective action by maintaining a duty cycle between 0.2 and 0.8, which guarantees that the CO2 flow is active for sufficient portions of the treatment time. The solenoid valve's rapid response capability ensures that when opened, the full therapeutic effect is delivered continuously without interruption, reducing overall treatment duration while maintaining efficacy
Solution Approach 2:
The dynamic control system allows real-time adjustment of flow parameters during treatment. The ability to rapidly modulate the solenoid valve enables the system to maintain optimal flow conditions throughout the procedure, preventing delays and ensuring efficient delivery of the required CO2 dosage, thereby reducing treatment time
3Reliability
If conventional devices are used, then basic carboxytherapy can be delivered, but treatment effectiveness is insufficient
Solution Approach 1:
The patent incorporates pressure regulation means that respond to back pressure from the patient's tissue. This feedback mechanism automatically adjusts the CO2 flow rate and pressure to maintain optimal delivery conditions despite variations in patient anatomy or treatment depth, ensuring consistent and reliable treatment effectiveness without requiring complex manual adjustment
Solution Approach 2:
The patent replaces manual mechanical control with automated electronic control systems including solenoid valves and pressure regulation means. This substitution provides more precise and reliable control over CO2 delivery parameters, ensuring consistent therapeutic effectiveness while the modular design keeps the overall system manageable in complexity
