Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If nonlinear drive signals are used to control cryocooler compressors, then cooling capacity is achieved, but mechanical vibrations increase causing equipment damage and inefficiency
Solution Approach 1:
The patent transforms the drive signal from nonlinear to linear by changing the temporal distribution of power delivery. The linear drive signal distributes power uniformly over the compression cycle, contrasting with the nonlinear signal's concentrated power delivery. This parameter change in signal morphology reduces mechanical vibrations while preserving cooling capacity.
Solution Approach 2:
The patent replaces the traditional mechanical control approach with electronic/digital signal processing. A processor generates and outputs linear drive signals, substituting mechanical vibration sources with an electronically controlled system that delivers the same cooling function with reduced mechanical disturbance.
2Object-affected harmful factors
If linear drive signals are used to control cryocooler compressors, then mechanical vibrations are reduced, but system complexity increases due to signal processing requirements
Solution Approach 1:
The patent introduces a linearization component as an intermediary between the power source and the compressor. This component translates nonlinear drive signals into linear signals, acting as a mediator that preserves the simplicity of the original control system while achieving vibration reduction through signal transformation.
3Reliability
If nonlinear drive signals are used, then compressor operation is maintained, but equipment stress increases leading to potential damage
Solution Approach 1:
The patent applies beforehand cushioning by using linear drive signals to preemptively reduce mechanical stress on equipment. The uniform power distribution in linear signals prevents the stress concentration that occurs with nonlinear signals, protecting equipment before damage can occur.
