Method for measuring air flow from a ventilation valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring air flow from ventilation valves are unreliable and require additional tools, leading to inconsistent measurement results due to the need for a separate probe and lack of standardization in measurement location.
Innovation Solution
A measuring hose is attached directly to the end of the hollow spindle on the ventilation valve's truss, allowing for standardized air flow measurement without a separate probe, enhancing the structure's rigidity and enabling free positioning of the front plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate measuring probe is used to measure air flow, then measurement can be performed, but the measurement location cannot be standardized and additional tools are required
Solution Approach 1:
The patent combines the air flow measurement function directly into the ventilation valve structure by integrating a measuring hose connection into the spindle assembly. This eliminates the need for separate measuring probes and standardizes the measurement location at the spindle end, thereby improving measurement reliability while reducing setup complexity
Solution Approach 2:
The patent introduces a measuring hose as an intermediary component that connects directly to the spindle of the ventilation valve. This hose serves as the measurement interface, allowing air flow measurement at a standardized location without requiring additional probing tools, thus resolving the contradiction between measurement precision and device complexity
2Ease of manufacture
If the ventilation valve structure is simplified, then ease of manufacture improves, but structural rigidity and robustness decrease
Solution Approach 1:
The patent merges the hollow spindle function with the truss structure by fastening the spindle directly into the truss. This integration maintains structural rigidity and robustness while simplifying the overall valve design and manufacturing process, as the spindle becomes part of the existing structural framework rather than a separate component requiring additional support
