Fine water discharge device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nano-mist generators produce wide particle size distributions and negatively charged nano-mist, which can cause suction or repulsion against the human body, making it difficult for the mist to infiltrate the skin. Additionally, these devices are often complex and large due to the need for components like Peltier elements and high-voltage power supplies.
Innovation Solution
A fine water discharge device featuring a case with a flow path, an air blowing unit, a fine water generating unit with core-shell structured particles laminated on a honeycomb-shaped base material, an electrifying portion, and a control portion. The device transitions between adsorption and discharge states to generate uncharged fine water with a particle size of 50 nanometers or less, which easily infiltrates the skin without the need for a water tank or high-voltage power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If nano-mist is generated by crushing large water particles, then nano-sized mist can be produced, but particle size distribution widens and particles become negatively charged causing suction or repulsion against the human body
Solution Approach 1:
The invention changes the fundamental parameter of water particle generation from mechanical crushing to biological-inspired secretion. By using a gelatinous substance that naturally secretes fine water particles through osmotic pressure and concentration gradients, the system achieves uniform particle sizes (50 nanometers or less) without charge, eliminating the harmful suction or repulsion effects while maintaining narrow particle size distribution.
Solution Approach 2:
The invention replaces the mechanical crushing system with a chemical-biological system. Instead of using rotating members and centrifugal force to crush water particles, the system employs a gelatinous substance that naturally generates fine water particles through osmotic pressure and concentration gradients, eliminating mechanical complexity and harmful electrostatic charges.
2Manufacturing precision
If electrostatic atomizer uses high-voltage power supply and Peltier element, then nano-ion mist can be generated, but device becomes complicated and large in size
Solution Approach 1:
The invention extracts and removes the complex high-voltage power supply and Peltier element components from the system. By using a gelatinous substance that naturally generates fine water particles through osmotic pressure, the system achieves nano-sized mist generation without requiring high-voltage electronics or active cooling components, dramatically simplifying the device structure.
Solution Approach 2:
The gelatinous substance serves multiple functions simultaneously: it generates fine water particles through osmotic pressure, provides natural cooling through evaporation, and maintains particle size control without external intervention. This self-service mechanism eliminates the need for high-voltage power supplies, Peltier elements, and complex control systems.
3Productivity
If nano-mist generator uses water tank, air guide tube, and rotation member, then large amount of negative ions and nano-mist can be generated, but device becomes large in size
Solution Approach 1:
The invention replaces rigid components like water tanks and air guide tubes with a flexible gelatinous substance that can be contained in a thin-film structure. The gelatinous material itself serves as both the water source and the generation mechanism, eliminating the need for large water tanks and complex air guidance structures, thereby reducing device volume while maintaining high productivity.
4Productivity
If fine water particles are discharged with strong electric charge, then atomization efficiency is improved, but water particles cannot infiltrate the inside of horny layer surface of human body
Solution Approach 1:
The invention changes the electrical charge parameter from strongly charged to uncharged. By using a gelatinous substance that secretes particles through osmotic pressure rather than electrostatic atomization, the system maintains efficient atomization while producing uncharged particles that can easily infiltrate the skin's horny layer without repulsion.
