Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medical devices operate at full power, then diagnostic and treatment performance is improved, but noise level increases reducing patient comfort
Solution Approach 1:
The noise reduction component generates anti-noise sound waves before the harmful noise reaches the patient, creating destructive interference that cancels out the noise. The processing component predicts future noise based on historical data and generates counteracting sound waves in advance, preventing the harmful effect rather than merely responding to it after occurrence.
Solution Approach 2:
The noise reduction component acts as an intermediary between the noise source (medical device operation) and the patient. It introduces a intermediate sound wave that mediates the interaction by canceling the harmful noise through destructive interference, protecting the patient from the full impact of the device operating noise.
2Measurement precision
If gradient field switching is performed in superconducting magnetic resonance systems, then imaging quality is improved, but noise generation increases due to mechanical vibrations
Solution Approach 1:
The noise receiving component continuously monitors the acoustic noise environment and feeds this information back to the processing component. The processing component analyzes the feedback signal, identifies noise patterns from gradient field switching, and adjusts the anti-noise generation in real-time to effectively cancel the vibration-induced noise while maintaining imaging quality.
