Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closing devices for gas conduits fail to quickly and efficiently change flow rates, often causing turbulence, noise, and potential damage due to inadequate sealing and size constraints, while also being difficult to retrofit into existing systems.
Innovation Solution
A closing device with a base body and pivotable closing elements that are positively locked to each other, allowing for rapid transition between flow and blocking positions, featuring a compact design with a small extension in the gas flow direction and modular construction for easy integration into existing systems.

Engineering Contradiction Analysis
1Length of moving object
If the closing device is made compact with small extension in gas flow direction, then the size constraint is satisfied, but the sealing reliability may be compromised due to insufficient space for effective sealing mechanisms
Solution Approach 1:
The closing device is divided into multiple closing elements (at least two) that can be arranged in series along the gas flow direction. Each closing element contributes to the overall sealing function, allowing the device to achieve reliable sealing while maintaining a compact overall extension by distributing the sealing function across multiple smaller components rather than requiring a single large sealing mechanism
Solution Approach 2:
The closing elements are arranged not only along the gas flow direction but also in a radial or circumferential arrangement around the gas passage. This multi-dimensional arrangement allows the closing elements to work together to provide effective sealing across the entire gas passage cross-section while maintaining a compact axial extension, effectively utilizing space in multiple dimensions rather than just extending in the flow direction
2Stability of the object's composition
If the closing elements are positively locked to each other, then the structural stability is improved, but the device complexity increases due to additional locking mechanisms
Solution Approach 1:
The closing elements are designed with self-locking features that automatically engage when the closing elements are positioned adjacent to each other. The complementary bounding sides are shaped such that they naturally interlock under the influence of gas pressure or spring forces, eliminating the need for external locking mechanisms. The structure itself provides the locking function, achieving structural stability without adding device complexity
Solution Approach 2:
The locking function is merged with the sealing function of the closing elements. The same bounding sides that provide the sealing surface also provide the positive locking engagement. By combining multiple functions into a single structural feature, the device achieves structural stability without requiring separate locking mechanisms, thereby avoiding increased device complexity
3Productivity
If the closing device allows unhindered gas flow in open state, then the flow efficiency is improved, but the resistance to back pressure when closed may be insufficient
Solution Approach 1:
The closing device uses multiple closing elements that can be arranged to provide both wide opening for unhindered flow and sufficient closing force. When open, the closing elements are positioned to maximize the gas passage cross-section. When closed, multiple elements working in parallel provide cumulative sealing force and back pressure resistance, achieving both flow efficiency and sealing strength
Solution Approach 2:
The closing elements are designed with composite structural features combining flexible sealing surfaces with rigid support structures. The sealing surfaces can deform to conform to the gas passage walls for effective sealing under back pressure, while the rigid portions maintain the structural integrity and positioning. This composite design enables both unhindered flow when open and sufficient back pressure resistance when closed
