Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid control apparatuses fail to efficiently direct the spread of a liquid over a surface in a desired direction, limiting the effectiveness of heating and vaporization processes.
Innovation Solution
A liquid control apparatus featuring a mesh form body and a groove on the supply subject surface, where the mesh form body is woven into a mesh form to create multiple interfaces for spreading the liquid by interfacial tension, while the groove suppresses spreading in undesired directions, promoting it towards a heater or temperature sensor for improved heating and vaporization precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a mesh form body is provided to contact the supply subject surface to promote liquid spreading by interfacial tension, then the liquid can be supplied over a large surface area, but the liquid spreads in all directions including undesired directions away from the heater
Solution Approach 1:
The supply subject surface is segmented into different functional zones by introducing grooves that divide the surface. This segmentation creates distinct regions: a liquid supply region where liquid is supplied, and a heater region where heating occurs. The grooves act as barriers that guide liquid flow preferentially toward the heater region while preventing excessive spread in other directions, thus improving heating efficiency while maintaining adequate surface area coverage.
Solution Approach 2:
Different regions of the supply subject surface are given different functional qualities through the groove structure. The areas with grooves have suppressed liquid spreading capability, while the heater region is designed to receive concentrated liquid. This local differentiation ensures that liquid is directed to where it is most needed (the heater) rather than uniformly distributing across the entire surface, resolving the contradiction between surface area coverage and heating efficiency.
2Area of stationary object
If the liquid is allowed to spread freely over the supply subject surface, then the liquid covers a larger area, but the liquid spreads away from the heater reducing heating precision
Solution Approach 1:
The supply subject surface is divided into functionally distinct zones using grooves. This segmentation creates a controlled liquid flow path that ensures liquid is supplied to the heater region with appropriate precision. The grooves act as flow guides that maintain liquid within the desired area, preventing spread to regions that would compromise heating precision while still allowing adequate surface coverage for effective heating.
Solution Approach 2:
The groove structure creates local variations in surface properties that control liquid behavior. In regions with grooves, liquid spreading is suppressed to maintain precision. In the heater region, the surface is designed to accept and concentrate liquid for precise heating. This local quality differentiation resolves the contradiction between achieving sufficient surface area coverage and maintaining heating precision.
3Loss of energy
If grooves are added to suppress liquid spreading in undesired directions, then heating efficiency is improved, but the device complexity increases
Solution Approach 1:
Instead of making the entire surface complex, grooves are introduced only in specific locations where liquid flow control is needed. The grooves are strategically positioned to suppress spreading in undesired directions while leaving other areas simple and open. This localized approach to modifying surface structure achieves the heating efficiency improvement with minimal increase in overall device complexity.
Solution Approach 2:
The groove structure creates a controlled porous-like effect on the supply subject surface. The grooves act as channels and barriers that guide liquid flow without requiring complex three-dimensional structures. This approach achieves flow control functionality with a relatively simple surface modification that can be manufactured using conventional techniques, thus improving heating efficiency without significantly increasing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively directs the liquid to spread preferentially towards the heater or temperature sensor, enhancing heating efficiency and vaporization precision by controlling the liquid's spread through interfacial tension and the suppression groove.
Implementation Method 1
a plurality of interfaces are formed between the supply subject surface and the mesh form body. As a result, the liquid supplied onto the supply subject surface is caused to spread over the supply subject surface by interfacial tension between the plurality of interfaces
Implementation Method 2
A heater configured to heat the supply subject surface is provided in an interior of the main body
Implementation Method 3
spreading of the liquid to the side of the heater can be promoted. As a result, heating of the liquid by the heater can be promoted
Implementation Method 4
When the groove is formed in the supply subject surface, on the other hand, an interface is not formed between the supply subject surface and the mesh form body in a part where the groove is formed, and therefore spreading of the liquid is suppressed

AI summary
A liquid control apparatus that controls a spread of a liquid has a main body that has a supply subject surface onto which the liquid is supplied. The apparatus also has a mesh form body that is woven into a mesh form and provided to contact the supply subject surface. A heater that heats the supply subject surface is provided in an interior of the main body. A supply port is provided in the main body to supply the liquid from the interior of the main body to a part of the supply subject surface contacted by the mesh form body. A groove is provided in the supply subject surface to suppress spreading of the liquid from the supply port to a side opposite to the heater in an expanse direction of the supply subject surface.
