Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the end member is connected to the zeolite separation membrane by fitting or butting with heat-shrinkable film, then the structure is simple, but reverse pressure causes the end member to come out
Solution Approach 1:
The connection structure is divided into multiple functional components: an insertion portion with external threads on the end member, corresponding internal threads in the housing, and a sealing portion. This segmentation allows each component to perform its specific function while working together to prevent dislodgment under reverse pressure.
Solution Approach 2:
The end member is pre-assembled with the zeolite separation membrane before installation into the housing. The insertion portion is inserted into the membrane end in advance, and the sealing portion is positioned beforehand, ensuring proper alignment and sealing before the membrane is secured in the housing.
2Reliability
If the tubular member is fixed to the fixing member by screwing, then the connection is secure, but thread formation and screwing work take much time and labor
Solution Approach 1:
The connection system is segmented into the end member with integrated threading features and the housing with corresponding threaded receptacles. This allows the threading to be formed once during manufacturing rather than requiring field assembly, reducing labor time while maintaining secure connection.
Solution Approach 2:
The invention replaces complex multi-step mechanical assembly operations with pre-formed threaded connections that can be installed in a single operation. The external and internal threads are formed during manufacturing, eliminating the need for time-consuming thread formation and screwing operations during assembly.
3Productivity
If the zeolite separation membrane is exposed to fluid flow, then separation function is achieved, but vibration occurs causing abnormal sound and sealing deterioration
Solution Approach 1:
The support plate and sealing portion are designed to preemptively counteract vibration forces before they can cause damage. The support plate provides structural stabilization, and the sealing portion with its flexible material absorbs vibrational energy, preventing abnormal sounds and sealing deterioration while maintaining separation function.
Solution Approach 2:
The sealing portion acts as an intermediary between the zeolite separation membrane and the housing. Made of flexible material, it mediates the interaction by absorbing vibrational forces and maintaining sealing contact, thereby preventing vibration transmission that would cause abnormal sounds and sealing failure.
4Reliability
If damaged tubular separation membranes are replaced, then system reliability is restored, but operation must be stopped for a long time
Solution Approach 1:
The zeolite separation membrane is segmented into a modular design where the end member with insertion portion can be independently replaced. This allows damaged membranes to be quickly swapped by removing and replacing individual end members without complex disassembly, minimizing operational downtime while restoring system reliability.

AI summary
An object of the present invention is to provide a separation membrane module in which an end member is prevented from coming out even at the occurrence of a reverse pressure or the like. The invention relates to a separation membrane module which is equipped with a cylinder-shaped housing and a tubular separation membrane and which takes out a fluid which has permeated the tubular separation membrane. An end pipe is connected to one end portion of the tubular separation membrane; the end pipe is supported by a support plate which is disposed so as to traverse the housing; and an end plug is connected to the other end portion of the tubular separation membrane. The separation membrane module is further equipped with a coming-out preventive member.
