Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If corona discharge method is used to generate negative ions, then negative ion content is high and technology is mature, but harmful by-products (ozone and nitrogen oxides) are generated and electrostatic effects occur
Solution Approach 1:
The patent extracts and eliminates the harmful corona discharge process from the negative ion generation system. Instead of using electrical discharge, it employs a mechanical collision method where water molecules are accelerated and collide with a collision plate, directly producing negative ions without generating ozone or nitrogen oxides as by-products
Solution Approach 2:
The patent replaces the electrical field-based corona discharge mechanism with a mechanical field-based collision mechanism. High-pressure gas drives water molecules to collide with a collision plate, using mechanical energy to ionize water molecules and generate negative ions, thereby avoiding the harmful effects of electrical discharge
2Quantity of substance
If corona discharge method is used to generate negative ions, then negative ion content is high, but electrostatic effects limit widespread application
Solution Approach 1:
The patent removes the electrical discharge component entirely from the system, extracting the harmful electrostatic effects while retaining the beneficial negative ion generation function through a purely mechanical collision process
Solution Approach 2:
The patent substitutes the electrical field mechanism with a mechanical field mechanism, using high-pressure gas flow to accelerate water molecules into collision with a plate, thereby generating negative ions through mechanical impact rather than electrical discharge, which eliminates electrostatic effects
3Object-affected harmful factors
If filters are used to purify air, then solid particles are removed, but air quality is not fundamentally improved and negative ions are not generated
Solution Approach 1:
The patent merges the functions of particle removal and negative ion generation into a single collision process. The collision between water molecules and the collision plate simultaneously achieves both particle filtration and negative ion production, eliminating the need for separate filter components
Solution Approach 2:
The patent utilizes the phase transition of water from liquid to gas (water vapor) and then to ionized state through collision. The water molecules are vaporized, accelerated, and collided to generate negative ions, leveraging phase changes to achieve both purification and ionization functions

AI summary
An air negative ion generating apparatus realized by bumping against a collision surface by a high-pressure gas flow carrying water molecules includes a liquid container (1) and a cover body (2) snapped onto a top opening end of the liquid container (1), and the cover body (2) is provided with a high-pressure gas inlet pipe (6); a core assembly (4) is provided inside the cover body (2), and the core assembly (4) includes a liquid flow chamber (41), a collision component (42) and a liquid flow inlet (43); and a lower port of the high-pressure gas inlet pipe (6) faces the collision component (42), the liquid flow inlet (43) is located between the lower port of the high-pressure gas inlet pipe (6) and the collision component (42), the liquid flow inlet (43) is communicated with the liquid chamber (41), and a lower port of the liquid flow chamber (41) is fixedly connected with a liquid conduit (5) extending downwards. Therefore, when a high-pressure gas passes through the high-pressure gas inlet pipe (6), a high-speed gas flow rushes towards the collision component (42), and the high-speed gas flow generates a negative pressure at the liquid flow inlet (43) when passing through the liquid flow inlet (43), such that water is sucked up through the liquid conduit (5) and mixed with the high-speed gas flow, thereby forming a gas-liquid mixture of the high-speed gas carrying liquid molecules; and when the gas-liquid mixture bumps against the collision component (42), negative ions will be generated.
