Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glass tube is used to surround the cathode, then the device structure is complete and enclosed, but the device becomes fragile and requires frequent replacement
Solution Approach 1:
The patent removes the glass tube from the ionization device structure entirely. The cathode is no longer enclosed by glass, eliminating the fragility issue while maintaining the essential ionization function through direct exposure of the electrode structure.
Solution Approach 2:
By eliminating the glass tube, the patent transforms the device from requiring expensive replacement of fragile components to using durable metal components that can be easily replaced or maintained without high cost.
2Use of energy by moving object
If a glass tube is used to enclose the cathode, then the structure is sealed, but energy consumption increases due to corona discharge
Solution Approach 1:
The glass tube that caused corona discharge is removed from the structure. The cathode operates without glass enclosure, eliminating the dielectric breakdown issue that produced harmful corona discharge and excessive energy consumption.
3Duration of action of stationary object
If a glass tube is used, then the device is enclosed, but the glass tube breaks down over time requiring expensive replacement
Solution Approach 1:
The glass tube is completely removed from the design, eliminating its time-dependent breakdown issue. The metal cathode structure provides indefinite service life without the degradation problems inherent to glass materials.
4Object-generated harmful factors
If high voltage is applied to break down glass dielectric strength, then the glass tube can be penetrated, but undesirable ozone is produced through corona discharge
Solution Approach 1:
The glass tube that required high voltage breakdown is removed. The device operates at lower voltages without glass, eliminating the dielectric breakdown process that generated harmful ozone through corona discharge.
