Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cryotherapy machines are used, then effective cryotherapy treatment is achieved, but the device size becomes large and cumbersome, reducing portability
Solution Approach 1:
The device is divided into separate modular components including a handheld spray gun, a CO2 tank, and control elements. This segmentation allows the treatment mechanism to be portable while the tank can be separately positioned or refilled, resolving the contradiction between maintaining effective treatment capability and achieving portability.
Solution Approach 2:
The cryotherapy treatment function is extracted into a compact handheld spray gun that can be easily transported, while the CO2 storage tank is separated as a refillable component. This extraction allows the core treatment device to be portable without sacrificing treatment effectiveness.
2Reliability
If traditional cryotherapy machines are used, then cryotherapy treatment is provided, but the device requires specialized facilities and frequent travel, reducing accessibility
Solution Approach 1:
The device enables users to administer cryotherapy treatments themselves at home or any location without requiring specialized facilities. The self-service nature of the handheld device eliminates the need for professional facility visits, thereby improving accessibility and location flexibility while maintaining treatment capability.
3Length of moving object
If a portable cryotherapy device is created, then device portability is improved, but the device must be compact which may limit treatment effectiveness
Solution Approach 1:
The device uses pressurized CO2 gas to deliver the cryotherapy agent through a compact handheld spray mechanism. This pneumatic system allows effective cryotherapy treatment delivery in a portable form factor, as the pressurized gas provides the necessary force for effective spray application without requiring a large device.
4Productivity
If the device operates at high pressure, then CO2 flow control is improved, but the risk of frosting and dry ice formation increases
Solution Approach 1:
The device incorporates temperature and pressure sensors with control systems that dynamically adjust operating parameters to maintain CO2 in the liquid phase during spray. By monitoring and adjusting temperature and pressure parameters in real-time, the system prevents frosting and dry ice formation while maintaining effective CO2 flow rates for treatment.
