Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the oscillation circuit unit and injector device are separated (discrete structure), then the apparatus can be assembled with independent components, but the transmission distance of driving voltage and signals increases causing oscillation efficiency deterioration
Solution Approach 1:
The apparatus is divided into two separable modules: an oscillation circuit unit and an injector device. This segmentation allows independent manufacturing and assembly while maintaining functional integrity through optimized connection design with minimized transmission distance.
Solution Approach 2:
A coaxial cable serves as an intermediary element to transmit driving voltage and signals between the oscillation circuit unit and injector device, minimizing signal deterioration while allowing physical separation of components for ease of assembly and repair.
2Loss of energy
If the oscillation circuit unit and injector device are integrated (integral structure), then the transmission distance is minimized improving oscillation efficiency, but the apparatus size increases and repair becomes difficult
Solution Approach 1:
The integrated design is segmented into separable modules connected by coaxial cable, allowing the benefits of integration (minimized transmission distance) while maintaining the advantages of separation (compact size, ease of repair).
Solution Approach 2:
The connection between oscillation circuit unit and injector device is made dynamically adjustable through separable coaxial cable connections, allowing the system to switch between integrated and separated configurations based on operational needs.
3Loss of energy
If a coaxial cable is used for signal transmission, then signal deterioration is minimized, but manufacturing costs increase
Solution Approach 1:
A coaxial cable is used as an intermediary transmission medium that provides optimal signal transmission with minimal deterioration, justifying its cost through improved oscillation efficiency and reduced energy loss.
4Ease of manufacture
If the oscillation circuit unit is remote from the injector device, then heat management becomes difficult, but component separation is achieved
Solution Approach 1:
The coaxial cable serves as both an electrical connector and a thermal management intermediary, allowing physical separation of heat-generating components while maintaining electrical connectivity and providing a controlled thermal path.
