Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional gas transportation devices are miniaturized by stacking mechanical parts, then the device size is reduced, but the size precision and assembling precision deteriorate
Solution Approach 1:
The device is segmented into multiple functional modules (gas pumps, flow-guiding pedestals, gas outlet cover) that are arranged side by side rather than stacked. This modular segmentation allows each component to maintain its dimensional integrity while achieving overall device miniaturization, thereby resolving the contradiction between reduced device size and maintained manufacturing precision.
Solution Approach 2:
The invention transitions from a vertical stacking arrangement to a horizontal side-by-side arrangement of components. This dimensional change from vertical to horizontal configuration enables miniaturization while preserving assembly precision, as the side-by-side layout reduces cumulative dimensional errors that occur in stacked configurations.
2Volume of moving object
If mechanical parts are minimized to achieve miniature benefits, then the device becomes compact, but the product yield becomes low and inconsistent
Solution Approach 1:
By segmenting the device into standardized modular components that can be manufactured independently and assembled horizontally, the invention improves product yield consistency. Each module can be produced with optimal dimensions, reducing manufacturing defects and improving overall product yield compared to minimized stacked components.
3Device complexity
If single gas transportation device is used, then the device structure is simple, but the gas transporting capacity is insufficient
Solution Approach 1:
Multiple gas pumps are merged side by side within a single device structure, with their output channels converging into a common gas outlet. This merging of parallel pumping units increases the total gas transporting capacity while maintaining relatively simple device structure through the unified outlet design and integrated flow-guiding pedestals.
Solution Approach 2:
The invention increases gas transporting capacity by arranging pumps horizontally side by side rather than stacking them vertically. This lateral arrangement in another dimension allows multiple pumping units to coexist in a compact footprint while collectively delivering higher gas flow capacity through their converged output channels.

AI summary
A gas transportation device includes a gas outlet cover, plural flow-guiding pedestals and plural gas pumps. The gas outlet cover includes a gas outlet nozzle and a gas outlet cavity. The gas outlet nozzle and the gas outlet cavity are in communication with each other. Each flow-guiding pedestal includes a main plate, a protruding frame and a chamber frame. The main plate includes a recess and a communicating aperture in communication with the recess. The gas pumps are disposed inside the chamber frames of the flow-guiding pedestals, respectively. The gas outlet cover covers the flow-guiding pedestals and is connected to the protruding frames, whereby plural convergence chambers are defined and are in communication with the gas outlet cavity. Consequently, the gas is transported through the recesses, the communicating apertures, the convergence chambers and the gas outlet cavity sequentially, and finally is discharged out from the gas outlet nozzle.
