Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ventilation systems face challenges in adjusting volume flow effectively across different operating pressures due to the complexity and cost of controllable valves, which are susceptible to damage and require additional components to handle turbulent flow patterns.
Innovation Solution
A tube insert with a base body and closure elements that adjust the cross-sectional area of the pipe to control fluid flow, allowing for adjustable volume flow without the need for valves, using a combination of connection channels and closure elements made from flexible materials to achieve laminar flow and precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If controllable throttle valves are used to adjust volume flow at different operating pressures, then volume flow control is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The base body is divided into multiple connection channels (at least two, preferably 3-20 channels) that can be independently closed by individual closure elements. This segmentation allows precise volume flow adjustment by selectively closing specific channels, replacing the need for complex adjustable throttle valves while maintaining ease of operation.
Solution Approach 2:
The invention extracts the essential flow control function from complex adjustable valves and implements it through a simple base body with multiple connection channels and basic closure elements. This removes unnecessary valve components while preserving the core volume flow adjustment capability.
2Ease of operation
If controllable throttle valves are used to adjust volume flow, then volume flow control is improved, but manufacturing cost increases
Solution Approach 1:
The base body and closure elements are designed as simple, inexpensive components that can be mass-produced using conventional manufacturing methods. The closure elements are basic blocking components rather than complex valve mechanisms, significantly reducing manufacturing cost while maintaining volume flow control functionality.
Solution Approach 2:
Instead of manufacturing expensive adjustable valves, the invention uses multiple identical or similar connection channels and closure elements. The base body can be mass-produced with standardized channels, and closure elements are simple replicas that can be manufactured economically in large quantities.
3Ease of operation
If valves are used in turbulent flow conditions, then volume flow control is achieved, but susceptibility to damage and errors increases
Solution Approach 1:
Instead of trying to make valves resistant to turbulent flow damage, the invention inverts the approach by using simple closure elements that are inherently resistant to damage. The closure elements are basic blocking components without moving parts or sensitive mechanisms, making them immune to turbulent flow-induced damage while still achieving volume flow control.
Solution Approach 2:
The closure elements are designed to function autonomously in turbulent flow conditions without requiring additional protective mechanisms or complex valve designs. The simple geometric shape and material properties of the closure elements allow them to withstand turbulent flow naturally, eliminating susceptibility to damage.
4Ease of operation
If adjustable throttle elements are included in valves, then volume flow adjustment is improved, but production costs and susceptibility to errors increase
Solution Approach 1:
The base body is divided into multiple connection channels (at least two, preferably 3-20 channels) that can be independently closed by individual closure elements. This segmentation allows precise volume flow adjustment by selectively closing specific channels, replacing the need for complex adjustable throttle valves while maintaining ease of operation.

Implementation Method 1
the cross-sectional area of the tube through which fluid can flow is reduced to the desired extent by inserting the closure element into the connecting channel of the base body
Implementation Method 2
The controlled passage of the fluid through the tube insert according to the invention reduces the turbulence and the fluid flow leaving the tube insert approximates a laminar flow pattern overall
