Existing gas flow measuring devices for building ventilation systems are cumbersome to handle when adjusting ventilation systems, requiring manual positioning and lacking efficient attachment mechanisms.
Innovation Solution
A gas flow measuring device with a fastening interface for detachable quick-fixing to a gas outlet opening, featuring a movable vane for measuring gas flow deflection, and a combination with a gas outlet opening using a matching counter-mounting interface, preferably with magnets, allowing tool-free separation and easy attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning is used to hold the measuring device in front of a gas outlet opening, then the device can be positioned for measurement, but the handling becomes cumbersome and time-consuming
Solution Approach 1:
The mounting interface is divided into two separate parts: a fastening interface on the measuring device and a counter-fastening interface on the gas outlet opening. This segmentation allows the measuring device to be quickly attached and detached without tools, resolving the contradiction between ease of operation and time loss during positioning.
Solution Approach 2:
A magnetic mounting interface acts as an intermediary mechanism between the measuring device and the gas outlet opening. The magnet and ferromagnetic material create a quick-connect device that enables tool-free attachment and detachment, significantly improving handling ease while reducing positioning time.
2Ease of operation
If a fastening interface with magnet and ferromagnetic material is used for quick attachment, then tool-free attachment is achieved, but the device complexity increases
Solution Approach 1:
The mounting interface serves multiple functions: it provides secure attachment during measurement, enables quick detachment for relocation, and requires no additional tools or complex mechanisms. By integrating the magnet and ferromagnetic material directly into the interface, the design achieves multi-functionality without proportionally increasing complexity.
3Reliability
If the measuring device is permanently installed within a flow guide, then stable measurement is achieved, but the adaptability to different gas outlet openings is reduced
Solution Approach 1:
The measuring device transitions from a permanent fixed installation to a dynamic, movable configuration. The detachable mounting interface allows the device to be easily moved between different gas outlet openings while maintaining measurement stability during use, thus achieving both reliability and adaptability.
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
Facilitates precise and temporary positioning without manual handling, simplifying the measurement process and improving handling efficiency by enabling tool-free attachment and detachment.
Implementation Method 1
it can also be that the mounting interface includes a magnet and the counter-mounting interface at the gas outlet opening is simply formed from ferromagnetic material, in particular from magnetizable metal
Implementation Method 2
the measuring device has a vane around which the gas flow is directed and which is movably mounted... by measuring the deflection of said vane
