Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the MRI system is securely mounted to prevent movement during transport, then reliability is improved, but the system becomes more vulnerable to quenching from vibrations
Solution Approach 1:
The mounting structure incorporates vibration-damping elements and shock-absorbing features that are pre-installed to cushion the magnet against vibrations and shocks during transport. This beforehand cushioning reduces the amplitude of vibrations reaching the magnet, thereby minimizing eddy current heating while maintaining magnet stability and preventing quenching incidents.
2Object-affected harmful factors
If the magnet is allowed to move freely during transport, then vibration-induced heating is reduced, but the system becomes unstable and may detach
Solution Approach 1:
The mounting structure uses flexible mounting elements and vibration-damping materials that allow controlled movement of the magnet while filtering out harmful vibrations. These flexible components act as vibration isolators, permitting the magnet to move slightly to reduce eddy current heating while still providing sufficient restraint to maintain stability and prevent detachment during transport.
3Reliability
If a rigid mounting structure is used to secure the MRI system, then stability is improved, but the system becomes more susceptible to damage from shocks and impacts
Solution Approach 1:
The mounting structure incorporates shock-absorbing elements and energy-dissipating features designed to cushion the magnet against sudden impacts and shocks during transport. These beforehand cushioning elements deform or absorb impact energy, protecting the magnet from damage while maintaining operational stability under normal transport conditions.
4Productivity
If the magnet is quickly secured upon arrival, then operational readiness is improved, but the risk of quenching from rapid positioning increases
Solution Approach 1:
The mounting structure is designed with pre-positioned mounting points, alignment features, and quick-secure mechanisms that enable rapid positioning of the magnet upon arrival. The preliminary design of these features allows the magnet to be quickly secured in the correct position without requiring complex adjustment procedures, thereby improving operational readiness while maintaining magnet stability through pre-engineered secure mounting configurations.
