Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional humidification modules using electrostatic spray methods face limitations due to the distance between the nozzle and electrode plate, leading to uneven voltage supply and reduced charging efficiency, and they often require complex voltage structures that increase production costs and safety risks.
Innovation Solution
A humidification module design where nozzles penetrate holes in a non-conductive substrate with electrodes arranged around them, allowing for direct voltage induction, and incorporates a hydrophilic fine structure to enhance capillary action and uniform water distribution, along with an electrolyte removal system to ensure stable and efficient droplet generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional double voltage structure with facing nozzle and electrode plate is used, then voltage can be supplied to both nozzle and electrode plate, but the distance between them restricts smooth voltage supply and reduces charging efficiency
Solution Approach 1:
The patent extracts the voltage supply function from a separate electrode plate and integrates it directly into the nozzle structure. The nozzle is designed with a conductive material that serves as both the spraying component and the voltage receiving electrode, eliminating the need for a separate electrode plate and its associated voltage supply system.
Solution Approach 2:
The patent merges the nozzle and electrode plate into a single integrated component. The nozzle is constructed with conductive material that allows it to function as both the liquid delivery component and the voltage receiving electrode, simplifying the overall structure to a single voltage supply system.
2Ease of operation
If the distance between nozzle and electrode plate is increased, then assembly is easier, but voltage supply becomes less smooth and charging efficiency decreases
Solution Approach 1:
The patent removes the separate electrode plate component entirely, extracting its voltage receiving function and integrating it into the nozzle structure. This eliminates the distance issue between separate components while maintaining ease of assembly through the simplified single-component design.
3Reliability
If a conductive substrate is used for the electrode plate, then voltage conduction is good, but safety is reduced and production cost increases
Solution Approach 1:
The patent applies local quality by making only the necessary portions of the nozzle conductive - specifically the regions that contact or are closest to the water stream. The rest of the nozzle structure can be non-conductive, providing electrical insulation while maintaining effective voltage transfer to the water at the critical locations.
Solution Approach 2:
The patent employs composite material construction for the nozzle, combining conductive materials in specific regions with non-conductive materials in other regions. This allows the nozzle to have both electrical conduction where needed for voltage transfer and electrical insulation where needed for safety.
