Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electromagnetic clutch is used to release compression during power failure, then compression can be released in complete power interruption, but it fails to release compression during unstable power supply conditions
Solution Approach 1:
The lifting device segments the power supply dependency by introducing a dual-mode operation: motor-driven lifting for normal operation and manual cranking for emergency release. This segmentation allows the system to function reliably across different power supply conditions by separating the lifting function from the release function.
Solution Approach 2:
The manual cranking mechanism enables the system to service itself during power failures or unstable conditions. The operator can directly crank the lifting pulley to release compression without relying on external power supply or electromagnetic clutch functionality, making the system self-sufficient in emergency conditions.
2Device complexity
If compression force is determined by predetermined manual value or repulsive force detection, then the control system is simple, but patient discomfort increases due to inability to accommodate individual biometric variations
Solution Approach 1:
The lifting device transforms the static compression force determination into a dynamic, adjustable parameter. The manual cranking mechanism allows real-time adjustment of compression force based on patient response and biometric characteristics, enabling the system to adapt to individual needs while maintaining simple hardware architecture.
3Device complexity
If uniform compression force is applied to all patients, then the control system is simple, but image quality deteriorates when patient movement occurs due to pain
Solution Approach 1:
The device enables dynamic adjustment of compression force during the imaging process. If patient movement is detected or pain is indicated, the operator can manually crank the lifting pulley to reduce compression force, thereby maintaining patient stillness and ensuring high-quality imaging without requiring complex automated control systems.
4Reliability
If quick release mechanism is added for emergency situations, then compression can be released during power failure, but device complexity increases
Solution Approach 1:
The lifting device merges the emergency release function with the normal lifting mechanism. The manual cranking capability is integrated into the existing lifting pulley system, allowing the same mechanical structure to serve both lifting and emergency release functions, thereby minimizing additional complexity while ensuring reliable emergency release.
