Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a carbon brush is used to generate ions, then ion emission is achieved, but the carbon brush becomes contaminated due to surrounding charges and air flow
Solution Approach 1:
A gate electrode is introduced as an intermediary component between the power supply and the carbon brush. This gate electrode controls the electric field distribution to enhance ion emission while protecting the carbon brush from direct exposure to harmful air flow and charge accumulation, thereby resolving the contradiction between maintaining ion emission performance and preventing contamination.
Solution Approach 2:
The patent modifies the electric field parameters by introducing a controllable gate electrode that adjusts the voltage distribution around the carbon brush. By changing the electric field configuration through the gate electrode, the system achieves improved ion emission while reducing the harmful effects of charge accumulation and air flow on the carbon brush surface.
2Productivity
If high voltage is applied to the carbon brush to improve ionization rate, then ion emission efficiency increases, but power consumption increases
Solution Approach 1:
The gate electrode enables dynamic adjustment of electric field parameters, allowing the system to achieve high ionization rates through optimized field distribution rather than simply increasing voltage magnitude. This controlled parameter modification improves ion emission efficiency while managing power consumption levels.
Solution Approach 2:
The gate electrode provides dynamic control over the electric field configuration, allowing real-time optimization of ion emission performance. This dynamic adjustment capability enables the system to maintain high ionization rates while adapting power consumption to actual operational needs, resolving the trade-off between productivity and energy use.
