Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If synchronous pulse generator and clock pulse generator operate independently, then device complexity is reduced and ease of operation is improved, but phase uniformity of output waveforms deteriorates causing jitter
Solution Approach 1:
The patent implements a feedback control mechanism where the actual phase difference between synchronous and clock pulses is measured and used to adjust the clock pulse generation timing. The control unit continuously monitors phase alignment and modifies the clock pulse phase to compensate for deviations, ensuring stable phase relationships while maintaining independent generator operation.
Solution Approach 2:
The patent replaces mechanical synchronization methods with electronic phase detection and control. Instead of mechanically coupling the pulse generators, the system uses electronic circuits to detect phase differences and digitally control the clock pulse timing, achieving precise phase alignment without physical connections.
2Stability of the object's composition
If feedback control with matching network is added, then phase stability is improved, but device complexity increases and response speed decreases
Solution Approach 1:
The patent extracts the phase control function from the traditional matching network and implements it directly within the pulse generation system. By removing the external matching network requirement and integrating phase adjustment into the clock pulse generator control unit, the system achieves phase stability without adding external complexity.
Solution Approach 2:
The control unit in the patent performs multiple functions: generating clock pulses, detecting phase differences, calculating required adjustments, and outputting corrected timing signals. This multi-functional approach eliminates the need for separate matching networks while maintaining phase stability.
3Ease of manufacture
If conventional separate pulse generation is used, then ease of manufacture is improved, but manufacturing precision of phase alignment deteriorates
Solution Approach 1:
The patent changes the control parameter from fixed mechanical timing to adjustable electronic phase parameters. By allowing digital adjustment of clock pulse timing based on detected phase differences, the system achieves high precision phase alignment while maintaining the simplicity of separate generator implementation.
