Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrostatic atomization is used to collect chemical substances from gas samples, then the detection sensitivity is improved, but the electrode is damaged due to collision with electric-charged fine particles
Solution Approach 1:
The patent divides the electrode system into multiple components: atomizing electrode, intermediate electrode, counter electrode, and detecting electrode. This segmentation allows the atomizing electrodes to handle the high-voltage electrostatic atomization process while the detecting electrode separately performs the detection function, protecting it from direct damage by electric-charged fine particles.
Solution Approach 2:
The patent extracts the detection function from the atomization process by using a separate detecting electrode. The detecting electrode is positioned to detect chemical substances after they have been atomized and charged, rather than being part of the high-voltage atomization structure itself, thus avoiding direct damage.
2Productivity
If high voltage is applied to collect electric-charged fine particles, then the collection efficiency is improved, but the detector is damaged electrically
Solution Approach 1:
The patent segments the electrical system into multiple electrodes with different voltage roles. The atomizing electrode and counter electrode handle high voltage for efficient collection, while the detecting electrode operates at lower voltage for stable detection, preventing electrical damage.
Solution Approach 2:
The patent introduces an intermediate electrode as a mediator between the atomizing electrode and the detecting electrode. This intermediate structure helps to gradually transition the electrical potential and protects the detecting electrode from direct exposure to high voltage while maintaining collection efficiency.
3Strength
If the analyzing device structure is divided into separate recovery equipment and detector, then the electrode is protected from damage, but the condensate liquid is lost during transfer
Solution Approach 1:
The patent merges the recovery and detection functions into a single integrated chamber structure. The detecting electrode is positioned within the same chamber where condensate liquid is collected, eliminating the need for external transfer equipment and preventing condensate liquid loss during transfer while still protecting the electrode through proper positioning and segmentation.
4Strength
If carrying means such as syringe or capillary is used to transport condensate liquid, then the electrode is protected from collision damage, but the chemical substance is lost due to remaining liquid in the carrying means
Solution Approach 1:
The patent extracts the condensate liquid from the carrying means and directly introduces it into the detection chamber. The detecting electrode detects chemical substances in the condensate liquid while it is still in the chamber, eliminating the need for external carrying means and preventing loss due to liquid remaining in syringes or capillaries.
