Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple gas guide paths are arranged to release bubbles toward different portions of the filtration membrane, then the coverage area of bubble contact is improved, but the synchronization of bubble release becomes difficult
Solution Approach 1:
Multiple gas guide paths are merged into a single integrated gas guide structure with a unified gas supply channel. This allows gas to be supplied simultaneously to all guide paths through one common channel, ensuring synchronized bubble release while maintaining coverage across multiple portions of the filtration membrane.
Solution Approach 2:
The single gas guide structure serves multiple functions: it distributes gas to multiple guide paths, maintains uniform gas flow distribution, and ensures synchronized operation. This multi-functional design achieves both wide coverage and precise synchronization without requiring separate control systems for each path.
2Manufacturing precision
If gas supply speeds to multiple gas guide paths are made uniform, then bubble release synchronization is improved, but the device complexity increases
Solution Approach 1:
Multiple gas supply channels are merged into a single common gas supply channel that distributes gas to all guide paths simultaneously. This eliminates the need for multiple independent control systems, reducing device complexity while ensuring uniform gas supply and synchronized bubble release.
Solution Approach 2:
The common gas supply channel creates equipotential gas distribution by providing equal pressure and flow conditions to all guide paths. This passive equalization approach achieves synchronized bubble release without requiring active control mechanisms, thereby simplifying the overall device structure.

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 enables simultaneous and uniform release of bubbles across a filtration membrane, enhancing scrubbing efficiency and membrane cleaning effectiveness.
Implementation Method 1
A gas is supplied from the outside into the liquid in a liquid storage path, floats in the liquid, and is stored in the upper portion of the liquid storage path. As the storage amount of the gas in the liquid storage path increases, the gas eventually enters the gas guide path from the upper portion of the liquid storage path. In the gas guide path, the gas moves to the below while pushing down the liquid in the gas guide path, and is directed toward the folded-back portion of the gas guide path. The gas that has reached the folded-back portion of the gas guide path is connected to the gas in the subsequent gas storage chamber, and floats at once while pushing up the liquid existing on the downstream side of the folded-back portion. Then, the gas is released as bubbles from the opening on the outlet side of the gas guide path.

AI summary
A bubble generation device capable of causing bubbles to hit filtration membranes almost simultaneously includes a housing having side plates and a top plate fixed to the side plates; bubble release ports disposed therein and arranged along a longitudinal direction of the top plate; and a bubble release chamber disposed in the housing and communicated with the bubble release ports. A folded-back path is formed by at least a folded-back plate and an inner plate disposed therein. One end and another end, respectively, of each of the folded-back plate and the inner plate in the longitudinal direction, are fixed to one of the two side plates and another of the two side plates, which face each other. One side and another side, respectively, of the folded-back path in the lateral direction are communicated with the bubble release chamber and a gas storage chamber.
