A thin profile gas transporting device comprising a gas collecting plate, a valve sheet, a discharge sheet, and a gas pump, where the gas pump introduces gas through convergence holes and a through hole to push valves, allowing gas to be discharged while preventing backflow through pressure relief holes, with a design that minimizes noise and enhances efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If conventional motors and fluid valves are used for fluid transmission, then fluid transmission function is achieved, but noise is produced during operation
Solution Approach 1:
The patent removes the conventional motor and fluid valve components that generate noise, replacing them with a passive thin profile device that uses pressure differential and surface tension to control fluid flow. This extraction of noisy components directly eliminates the harmful noise factor while maintaining fluid transmission functionality.
Solution Approach 2:
The invention replaces the active mechanical system (motor-driven pump and valve) with a passive physical system utilizing pressure differential, surface tension, and capillary action. This substitution eliminates mechanical noise generation while achieving the same fluid transmission and control functions.
2Volume of moving object
If conventional motors and fluid valves are used, then fluid transmission is achieved, but the device size is large
Solution Approach 1:
The patent transitions from a three-dimensional bulky motor-valve assembly to a two-dimensional thin profile structure. The fluid transmission channels are arranged in planar layers, allowing the device to achieve comparable transmission capability in a dramatically reduced volume by utilizing dimensional reconfiguration.
Solution Approach 2:
The invention employs thin film structures for the device body, channels, and valve components. These thin films maintain structural integrity and fluid transmission functionality while minimizing thickness and overall device volume, enabling miniaturization without sacrificing productivity.
3Object-generated harmful factors
If conventional fluid valves are used for gas transmission, then gas transmission function is achieved, but noise is produced during pressure relieving
Solution Approach 1:
The patent creates a simplified copy of the valve function using passive physical principles rather than active mechanical components. The pressure relief is achieved through pressure differential-driven flow through the thin profile channels, replicating the pressure control function without the noise-generating mechanical valve opening and closing actions.
Solution Approach 2:
The invention utilizes pneumatic principles where gas pressure differential drives the flow through the thin profile channels. The pressure relief mechanism relies on hydraulic/pneumatic pressure balance and surface tension effects rather than mechanical valve actuation, eliminating noise during pressure relief operations.
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 device achieves rapid and quiet gas transmission with reduced noise during pressure relief, enabling a miniaturized, efficient, and quiet operation, addressing the issues of noise and size in conventional fluid transmission systems.
Implementation Method 1
the gas is introduced into the gas collecting plate and passes through the convergence holes and the through hole of the gas collecting plate to push the discharge valve and the pressure relief valve
Implementation Method 2
When the discharge valve is pushed by the gas, the discharge valve bends downward to detach from the convergence protrusion and open the valve hole

AI summary
A thin profile gas transporting device includes a gas collecting plate, a valve sheet, a discharge sheet, and a gas pump. The gas pump is disposed on the gas collecting plate. The gas collecting plate, the valve sheet, and the discharge sheet are stacked and assembled sequentially. Through simplifying the structures of the gas collecting plate and the discharge sheet, the thicknesses of the gas collecting plate and the discharge sheet can be reduced. Moreover, through the arrangement of several pressure relief holes, the pressure relieving operation can be performed rapidly and quietly.
