Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a coil is used to generate a magnetic field for electromagnetic therapy, then treatment efficiency is improved, but heat is generated that requires management
Solution Approach 1:
A cooling fan is introduced as an intermediary component between the coil and the external environment. The fan actively moves air across the coil surface, serving as a mediator to transfer heat from the coil to the surrounding air, thereby managing the thermal byproduct of magnetic field generation without interfering with the therapeutic function
Solution Approach 2:
The patent employs pneumatic cooling by using a fan to generate airflow that passes over the coil. This pneumatic system utilizes air movement to convect heat away from the coil, providing an effective thermal management solution that maintains treatment efficiency while controlling temperature rise
2Productivity
If the energy concentration rate is improved for magnetic field generation, then treatment efficiency increases, but heat management becomes more critical
Solution Approach 1:
The cooling fan acts as an intermediary thermal management system that addresses the increased heat generation resulting from improved energy concentration. By introducing active air cooling, the system can sustain higher energy density in the coil without allowing excessive temperature buildup that would compromise safety or performance
3Ease of manufacture
If the coil mounting structure is restricted to improve energy concentration, then manufacturing simplicity is maintained, but heat dissipation efficiency is reduced
Solution Approach 1:
The patent introduces a pneumatic cooling system that compensates for the limited heat dissipation capacity of the simple coil mounting structure. The fan-generated airflow provides enhanced convective cooling, allowing the mounting structure to remain simple and easy to manufacture while still achieving effective heat dissipation through improved air circulation
