Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional air duct passage is used to connect the measuring device to the air vent, then the measuring device can be positioned remotely, but air leakage and turbulence occur that adversely affect measurement precision
Solution Approach 1:
The air ducting system is divided into multiple modular air duct units that can be connected together. Each unit has standardized coupling ends, allowing the system to be segmented into manageable sections that can be assembled and disassembled. This segmentation enables precise fitting to the air vent geometry while maintaining airtight connections throughout the duct passage.
Solution Approach 2:
The air duct units are designed with universal standardized coupling ends that can connect to various measuring devices and air vent configurations. This universality allows the same duct unit design to be used in different measurement scenarios, ensuring consistent airtight performance across multiple applications while eliminating the need for custom-fitted ducts for each measurement setup.
2Reliability
If multiple custom air duct designs are manufactured for different measuring devices, then each device can be optimally connected, but manufacturing and storage costs increase
Solution Approach 1:
The air duct units feature standardized coupling ends that can universally connect to different measuring devices and air vent types. This universal design allows a single air duct unit to serve multiple functions and compatibility with various devices, significantly reducing the number of different duct designs that need to be manufactured and stored while maintaining reliable connections.
Solution Approach 2:
The system is segmented into standardized modular units with uniform coupling interfaces. This segmentation allows for mass production of identical or limited-variant duct units that can be combined in different configurations, reducing manufacturing complexity and inventory requirements compared to producing custom-integrated solutions for each device type.
3Ease of operation
If the air ducting system uses non-standardized components, then each component can be optimized for its specific function, but system complexity and assembly difficulty increase
Solution Approach 1:
The air ducting system is divided into multiple air duct units with standardized coupling ends. Each unit can be independently manufactured and optimized for its specific function, yet the standardized interfaces simplify assembly by ensuring compatibility across all units. This segmentation with standardization reduces system complexity despite functional diversity.
Solution Approach 2:
The coupling ends are designed to enable dynamic assembly and disassembly of the air duct units. The standardized interfaces allow for quick connection and detachment without requiring complex alignment procedures or specialized tools, making the system adaptable and easy to operate while maintaining functional optimization of each unit.

AI summary
An air ducting system is provided for ducting an air flow emerging from an air vent, which serves to introduce an air flow directly into a passenger compartment of a vehicle, to a measuring device for measuring of at least one parameter of the air flow. The measuring device includes at least one collector unit for collecting the air flow emerging from the air vent, which can be arranged on the air vent in such a way that a contact face of the collector unit completely encloses at least one outlet aperture of the air vent. In order to improve a measurement of at least one parameter of the air flow, the air ducting system comprises at least two air duct units of different design, either of which can be connected to and non-destructively detached from the collector unit.
