Flexible Sealing Coupling With Torque Compensation for Duct Tightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid distribution duct coupling systems suffer from deformation and loss of tightness due to fluid pressure, causing the sealing screws to deviate and lose their position, leading to defects in the coupling.
Innovation Solution
Incorporation of circumferential compensation means, including additional screws and transversal joining shafts with elastic rings, to counteract the deformation caused by fluid pressure, ensuring the sealing screws return to their original position and maintain optimal coupling functionality.

Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid closure assembly is used to ensure structural stability, then the coupling maintains its shape, but the sealing screw deviates under fluid pressure causing loss of tightness
Solution Approach 1:
The closure assembly transitions from a rigid structure to a dynamic flexible structure that can adapt its shape. The flexible closure body is designed to deform elastically under fluid pressure, allowing the sealing screw to maintain its sealing position while the overall structure remains stable through controlled deformation rather than rigid resistance.
Solution Approach 2:
The material properties of the closure assembly are changed to provide flexibility. The closure body is made from flexible material that can undergo elastic deformation, changing its physical state from rigid to compliant, allowing it to absorb pressure-induced stresses without causing screw deviation.
2Reliability
If additional compensation means are added to counteract torque, then the sealing screw position is maintained, but the device complexity increases
Solution Approach 1:
The compensation function is merged into the closure body itself rather than being a separate mechanism. The flexible closure body inherently provides torque compensation through its elastic deformation characteristics, combining the sealing function and the compensation function into a single integrated component.
Solution Approach 2:
The flexible closure assembly serves itself by automatically compensating for torque effects through its inherent flexibility. When fluid pressure causes the sealing screw to experience torque, the flexible closure body deforms to counteract this torque, maintaining screw position without requiring external compensation mechanisms.
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 flexible closure assembly effectively prevents excessive deformation and maintains the integrity of the sealing coupling, ensuring optimal operation and tightness by compensating for the torque induced by fluid pressure.
Implementation Method 1
circumferential means for compensation of the torque that the pressure of the fluid can cause on the screw joining the respective members... providing an elastic closure system that avoids an excessive and unrecoverable deformation of the closure
